Geocache Description:


 

 

INTRODUCTION

 

Washington, DC

November 1940

 

Hitler has knocked the free world onto its heels as he continues his blitzkrieg across Europe. His list of conquests already includes Czechoslovakia, Poland, Denmark, Norway, France, Belgium, Luxembourg and the Netherlands. Now his army is peering across the English Channel at its next target, while Neville Chamberlain’s policy of appeasement has left Britain woefully unprepared for the coming onslaught. For several months the Luftwaffe has been bombing London nightly from its airstrips in Pas-de-Calais. A massive land invasion is the logical next step.

 

The United States is officially neutral, but president Roosevelt is doing everything in his power to assist the hawkish new Prime Minister, Winston Churchill. A massive convoy program sends boatloads of food, clothing and other supplies across the Atlantic. The Lend-Lease Act, still working its way through Congress, will extend unlimited credit to Britain for the purchase of American military hardware.

 

The covert war, however, is well underway. The U.S. Army Signals Intelligence Service (SIS) has sent a detachment of cryptography specialists to Bletchley Park to assist in the breaking of German codes and ciphers. That’s how I ended up here, doing what I’m doing now.

 

I’m Biff St. Clair, First Lieutenant, U.S. Army SIS. When I arrived at BP, the place was overflowing with kooks, misfits, longhairs and pretty-boys. They didn’t need, or want, me there. I volunteered to go back home, but that didn’t fly. They sent me instead to visit Sir Frank Nelson, head of Churchill’s Special Operations Executive (SOE), a clandestine army of kooks, misfits, longhairs and pretty-boys. Their mission: "set Europe ablaze," i.e., do anything and everything possible to disrupt Hitler’s Third Reich.

 

Not sure how I got so lucky (my whole life, so far, has been a series of lucky breaks) but SOE matched me with Mynx d’Meanor, a delectable little morsel from Singapore, a far east outpost of the British Empire. We are a team of covert “field agents.” Our mission: work behind enemy lines to help resistance groups in the Nazi-occupied countries set up secret communication networks.

 

BIFF & MYNX!


I immediately fell head-over-heels in love with Mynx – and I think the feeling is mutual. Despite that, we work together well, and have been highly effective in our first few assignments. Mynx is sharp as a razor and tough as nails, a 100-pound package of TNT with a short fuse.

 

Right now we are “on loan” to the SIS. That’s why we’re here in Arlington – waiting for our next assignment.

“Biff!” It’s the third time Mynx has slapped my wandering hands. “If you’ll keep your mind on business and help me with this, maybe we can get out of here in an hour or so!”

 

“Deal!” I agree. “One hour of intense effort, then we’re out of here!” Besides, my hands are getting sore.

 

It’s a magnificent autumn day in northern Virginia. Not a cloud in the turquoise sky, a brisk northwestern breeze. The maples are ablaze in red and yellow, which reminds me that, compliments of Lt. Col. Duncan Lee, Mynx and I have tickets for tomorrow’s Redskins-Pittsburgh Pirates game.

 

Today, however, we are stuck in this cramped office at Arlington Hall, working on the debriefing report from our last assignment. In that caper we provided radio communications for the Croix-de-Feu in their botched assassination attempt of Pierre Laval, the despised Nazi collaborator. Despite our best efforts it was a typical French operation – FUBAR from the beginning. Now, as Mynx puts it, we’ve got some ‘explaining’ to do.

 

Since lunch I’ve been lobbying Mynx to knock off early and take a bus back to DC. We both want to see the Reflecting Pool and climb Washington’s Monument. She, on the other hand, is adamant that we finish our report first. Mynx is right, of course (big sigh).

Office of the Chancellor, Berlin, Germany

Saturday 11/02/40, 11:48 PM

 

Adolph Hitler , a night owl at heart, holds his most important meetings late at night. He arrives rested and sharp, while his subordinates, having worked all day, are exhausted and want only to go to bed. This tactic helps assure their compliance with his crackpot orders and demands. Tonight the commanding officers of the Wehrmacht are assembled to hear the Fuehrer announce a plan that will shape the destiny and determine the fate of his “Thousand Year Reich.”

 

After a glowing recap of their recent conquests, Hitler comes to the point and purpose of tonight’s meeting. He reveals BARBAROSSA, his codename for Germany's plan to invade the Soviet Union. It has long been the centerpiece of Lebensraum, the motivation behind his plan to dominate Europe.

 

“Generals of the Oberkommando der Wehrmacht!” he is shouting and obviously excited. “It is my dictate that we commence OPERATION Barbarossa no later than June 1st, 1941!”

 

At this the generals leap to their feet, deliver the stiff-armed Nazi salute and offer a lusty “Sieg Heil, Fuehrer!” in response.

 

FVRT URVY, ZL NFF!

 

Office of the Chancellor, Berlin, Germany

Sunday 11/03/40, 1:23 AM

 

Hitler’s midnight pep rally is over. Despite their simulated enthusiasm in his presence, the military leaders are shaken at hearing of the Fuehrer's plan to invade Russia. As the meeting adjourns they file out of the conference room in silence. A few officers gather into small groups, whispering among themselves. Most leave the building immediately. Perhaps the phrase ‘impending doom’ best describes the true feeling that permeates the crowd tonight.

 

Afterwards, General Franz Halder, head of the Army General Staff, Luftwaffe Air Marshall Hermann Goering, Foreign Minister Joachim von Ribbentrop and Abwehr chief Wilhelm Canaris, meet privately with the Fuehrer to discuss details of BARBAROSSA. Hitler, oblivious to the negative impact of his announcement, is still excited. He raves about the operation and seems to carom off the walls with uncontrolled energy. Ten minutes into his overheated monologue, the frustrated Halder raises a hand to interrupt.

 

“But mein Fuehrer,” the General objects, “with all respect, we must consider the implications of fighting a war against two mighty enemies at the same time – the Soviets to our east and the Allies to our west.”

 

The room is suddenly silent with tension – and fear. Hitler glares at Halder for a moment that seems like an eternity to those present. He is obviously upset, as much for the disruption of his soliloquy as by the nature of the comment. Halder visibly wilts.

 

“Thank you, mein lieber Halder,” his voice is dripping with vitriolic sarcasm, “for bringing this elementary fact to my attention.”

 

“You may not be aware,” he explains, “that I have been planning this operation for many years. You must understand that without American military and industrial might the Allies are but a Paper Tiger. My plan includes a brilliant strategy to neutralize the Americans before they become involved in our war.”

 

“Please Fuehrer,” General Goering interjects, hoping to soothe Hitler’s temper and put him back on track. “You must share your most ingenious strategy with us!”

 

Ja, Gentlemen.” Hitler brightens noticeably as he resumes his train of thought. “The time has come for us to review the details of this intricate operation. All of you, I am certain, are familiar with the Zimmermann Telegram

 

A sharp intake of collective breaths is followed by stunned silence as the Fuehrer delivers his own version of the half-baked scheme that contributed much to Germany’s defeat in the Great War. Only the mutton-headed Ribbentrop remains unperturbed.

 

“Who is Zimmermann?” he asks Canaris in a low whisper. “Does he work for you?”

 

 

JUNG N QBBSHF!

Foreign Ministry, Berlin, Germany

Sunday 11/03/40, 11:26 AM

 

Joachim von Ribbentrop sits behind the desk in his elegantly appointed office. Oblivious to history and the current situation, he puts the finishing touches on a message that, once delivered, will initiate a series of events leading to the destruction of Germany and Hitler’s evil empire. He places his swastika-embossed fountain pen in its holder then presses a button on the desktop intercom.

 

“Miss Gruner,” he says. “Come into my office, please.”

 

Ja, Herrminister,” a sexy feminine voice replies.

 

Seconds later the owner of that voice enters the room. Lillian Gruner is a platinum blonde bombshell, tall and shapely, with a balcony that you could recite Shakespeare from. None of this is wasted on Ribbentrop, who hired Lillian precisely for her textbook Aryan attributes.

 

He once brought Lillian to a meeting at the Chancellery, hoping to impress Hitler with his new trophy. Ribbentrop was shocked to find instead that the Fuehrer was highly aggravated by her presence. He is, in fact, a lifelong misogynist who, by all accounts, lives a life of strict celibacy. The following day Hitler sent Ribbentrop a note, stating that Miss Gruner is not to attend future meetings.

 

Ribbentrop is too dim to realize it, but Lillian has an IQ that, if it were a bowling score, would easily crown her the PBA champion. She hides her powerful intellect from most people, using her stunning appearance as camouflage. In recent days, however, she has revealed her hopes and fears to the fatherly Wilhelm Canaris, over wine and candlelight dinners. He has much larger plans for Lillian – as a future Abwehr agent.

 

“Miss Gruner,” despite his baser instincts, Ribbentrop has always maintained a proper formal relationship with Lillian. “Please apply my special cipher to this message, then have it transmitted as soon as possible.”

 

“I will do this immediately, Herrminister.” She turns on a stiletto heel.

 

SNZBHF GI NPGERFF

“And Lillian,” He eyes her sternly. “This is highly confidential. You must return the original to me.”

 

Ja, Herrminister,” Lillian leaves the room to begin her task.

 

“Herrminister ist solch ein Dummkopf!” Lillian thinks as she returns to her desk in the outer office. She pulls a red leather journal from the wall safe hidden behind a larger-than-life-sized portrait of Die Fuehrer. Sometimes she wonders if that penetrating gaze can read her mind. She knows for a fact that her phone is bugged and that there is a microphone hidden in the base of the lamp on her desk. Ribbentrop tells her that this is merely standard Gestapo procedure.

 

Lillian pins the message to a small typist’s easel then opens her journal to the substitution table corresponding to today’s date. She looks at Ribbentrop’s message for the first time. On the second reading her hands begin to tremble and small beads of perspiration appear on her upper lip. She struggles to regain her composure as she returns the book and the message to her wall safe. Then she taps on Ribbentrop’s door.

 

Herrminister,” there is a slight strain in her voice. “I am going to lunch now. May I bring something back for you?”

 

Danke Fräulein Gruner,” Ribbentrop looks up and flashes a brief smile. “You are kind to think of me, but I must leave soon for a luncheon with Air Marshall Goering at Carinhall. I will be out for the rest of the day.”

 

Sehr gutter Herrminister,” with this news she relaxes somewhat. “Your message will be transmitted within the hour.”

 

“That will be sufficient,” he returns his attention to the report he is reading.

 

Lillian dons sensible shoes and her knee-length ermine coat then ventures out into the grey blustery weather. She walks several blocks then turns into a narrow side street. There she enters a phone booth and dials a number that is etched into her memory. She lets the phone on the other end ring twice then hangs up. Seconds later the pay phone rings. She picks up the handset and puts it to her ear.

 

Canaris,” a gravelly man’s voice. Lillian’s knees go weak.

“What a great game!” I leap to my feet as "Slingin’ Sammy" Baugh completes yet another forward pass. “GO REDSKINS!! YEAH!!

 

“I don’t understand,” Mynx complains. “Why do they keep hitting each other?”

 

“Like I told you,” I’ve tried to explain this to her before. “It’s a contact sport. Uniquely American – What!?” a sharp tap on the shoulder disrupts me in mid-sentence.

 

“You two. Come with me, please.” A gruff-looking Army sergeant motions us toward the nearest exit.

 

We jump to our feet and follow the soldier to a Jeep that sits idling at the main entrance. We know enough not to ask questions when the military summons. The sergeant grinds the transmission into gear, roars out of the parking lot and turns south onto Georgia Avenue.

 

It’s a long ride on a chilly day and the Jeep has no heater to speak of. Soon Mynx and I are huddling in the back seat for warmth. We find a heavy wool blanket in the back and wrap ourselves in it. One thing leads to another and pretty soon we’re necking passionately. I’m clumsily unbuttoning buttons and struggling to unsnap those pesky little snaps. Mynx is writhing with anticipation, which only makes my job more difficult.

 

“I’d like to know who designs women’s clothes,” I complain. “It certainly wasn’t a man!”

 

“You just need more practice, Silly!” Mynx giggles. She is like putty in my hands at times like this.

 

“Play time is over!” the sergeant grinds the little Jeep to a halt. “This is the end of the line!”

 

After a quick rearrangement of clothing, we enter Lieutenant Colonel Duncan Lee’s office at the SIS training camp, near Quantico. I still have vivid, though mixed, memories of my days here.

 

“Mynx! Biff! Great to see you both again!” Lee ushers them into his office.

 

“Hope you enjoyed the football game.” An aide enters with sandwiches and coffee. “How about a snack?”

 

“Sounds great!” I grab a bologna and cheese on wheat. “So was the game.”

 

“I don’t understand that sport at all,” Mynx complains. “Why is it called football, anyway?”

 

“That is confusing,” Lee admits. “But frankly, I brought you two down here to discuss something even more confusing – and possibly much more important.”

 

“Fire away, Dunc.” I say, munching on the sandwich. “I’m all ears.”

 

“This just came in today,” he scans a telegram as he speaks. “The details are still sketchy, but it looks like we’ve got Nazis smuggling gold into the southeastern US.” Suddenly he’s got my complete attention … and Mynx’s.

 

“That’s all we know at the moment.” He studies the report more closely then looks up. “The FBI says Abwehr agents are landing all along our southern Atlantic and Gulf coasts. They’re rowing to shore in rubber rafts launched from U-boats.”

 

“Saboteurs?” Mynx asks.

 

“Maybe,” Lee continues. “They’ve found a dozen rafts already. All Kriegsmarine issue.”

 

“What about the gold?” I ask.

 

“This morning they captured a couple of these spies near Biloxi. Each was carrying about twenty-five pounds of rare gold coins.” Lee lays the paper back on his desk. “They also had maps directing them to a small village in Tennessee.”

 

“Sounds like,” I conclude, “We’d better take the last train to Clarksville and check it out.”

 

“White House, actually.” Lee smiles at the future pun.

Alastair Denniston, head of the Government Code and Cypher School (GC&CS), stirs his tea absentmindedly as he skims the summary of wireless messages deciphered during the night. A light tap on the door derails his train of thought.

 

“Good morning, Peter.” Denniston motions Peter Calvocoressi, one of his most talented cryptanalysts, to a nearby chair. “A spot of tea, my boy?”

 

“Thank you, Sir,” waving it aside. “Couldn’t hold another drop, if you know what I mean.”

 

“Indeed.” Denniston squirms uncomfortably. TB (tiny bladder) is a terrible affliction, common amongst middle-aged British men.

 

“Here’s an interesting catch, Sir,” Calvocoressi passes a paper across the desk. “Just in from Beeston Bump.”

 

“Hmm… what do you make of it, Peter?” Denniston examines the enciphered communication thoughtfully. “Could it be another in the BONIFACE series?”

 

“Perhaps,” Peter replies. “But I’m not so sure.”

“The man is truly deranged!” Pushing aside the Fuehrer’s latest orders to Abwehr, Wehrmacht Field Marshall Walther von Brauchitsch sits at his desk groaning, head in hands.

 

“That’s why we must stop him for good.” The Admiral sits calmly, smoking a pungent Turkish cigarette. “We cannot allow Die Sphinkter to destroy our Fatherland.”

 

Canaris retrieves his orders, tucking the paper into his suit coat pocket. The chief of Abwehr, the German intelligence service, rarely wears his uniform, except at official military functions.

 

“An insane plan, Wilhelm!” von Brauchitsch recalls. “We all know that the Zimmermann debacle led to our defeat in the Great War. This is essentially the same tactic. We can only expect the same result!”

 

“All the more reason why we must revive the conspiracy, Walther.” Canaris rises and places a bony hand on the General’s shoulder. “This time we must keep our nerve and our wits about us. We will talk again soon.”

 

Canaris glides silently across the plush carpet and disappears behind the dark mahogany door.

The statuesque young beauty and the wizened old sailor make an incongruous couple as they sit in a private booth at the restaurant of this luxurious hotel. The Admiral’s comforting presence begins to make Lillian feel that she is doing the right thing, after all. The champagne reinforces her sentiment.

 

“Did you bring Ribbentrop’s message, my dear?” Canaris asks.

 

“Yes,” Lillian replies, pulling a slip of paper from inside her pushup bra. “I copied it word-for-word and hid it here.”

 

“Excellent!” without a glance he tucks the paper into his coat pocket. “You are a resourceful young lady.”

 

“Everyone thinks I’m just a ‘dumb blonde,’” she replies. “I don’t bother to contradict that impression. Frankly, I prefer to have people underestimate me.”

 

“A clever strategy,” Canaris strokes her hand lightly. Then he turns serious.

 

“You must understand,” he continues, “that by coming here tonight you are committing yourself to the Conspiracy. There is no turning back.

 

“Yes, Admiral.” She nods her assent. “After reading Ribbentrop’s message I am convinced that this plan will devastate Germany!”

 

“You speak the truth, my child,” Canaris whispers. “As of this moment you no longer work for that idiot Ribbentrop. You now work for the Conspiracy. We must destroy Hitler before he destroys us all!”

Mynx and I are rested, well fed and finally warm again, after Sunday’s Jeep ride. Duncan Lee is supposed to brief us on our new assignment sometime this morning. We’re sitting in an empty office on pins and needles, like a couple of kids waiting in line to see Santa Claus at Macy’s.

 

Ho! Ho! Ho!” I give her my best St. Nick imitation. “What do you want for Christmas, little girl?” Mynx hops on my lap and throws her arms around my neck.

 

“First I want a nice big juicy kiss!” She plants her soft red lips on mine and offers a long, wet smooch that sets the tone for the rest of this interview.

 

“Air!” I pant. “Santa needs air!”

 

“Next I want diamonds!” She kisses me again. “Diamonds the size of radishes!”

 

Ho! Ho! Ho!” Santa is beginning to smell a rat. “That’s a pretty tall order from such a tiny lass!”

 

“And furs!” Another kiss. “Preferably silver fox.”

 

“Hey! You must think Santa is made of money, or something!”

 

“You better believe it, Big Boy!” She’s moving in for the kill. “And if Santa wants what Mynxy’s got, then Santa better give Mynxy what she wants!”

 

I’m on thin ice here and we both know it. What I say next could have a big impact on my future sex life – and my wallet. Think, Biff! Don’t blow it!

 

Just then, a knock at the door – I’m saved, for the moment. Mynx gives me a dirty look then hops down to answer it.

 

“Zip up your fly, Santa.”

 

She throws open the door and there stands Duncan Lee. He steps cautiously into our office. In his hand, a manila folder stamped with words ‘Top Secret’ in bright red ink.

 

“Should I come back later?” he asks.

 

“No, no!” I straighten my tie. “We’ve been waiting for you. Trying to guess what our next assignment will be.”

 

“Wait no longer,” he says. “The information we need just came through a few minutes ago.”

 

We gather around the desk as Duncan pulls a telegram out of his folder and spreads it out before us.

 

“This is the key to our puzzle,” he says. “We believe that this message, once you decipher it, will give us some clues to what the Krauts are doing here.” He pauses. “That’s the first part of your assignment.”

 

“You want us to crack this code?” I’m somewhat incredulous. “We’re field agents, Duncan. Don’t you have more qualified people to work on this for us?”

 

“Well, yes… and no.” He explains. “My staff is covered up trying to track the Japanese fleet in the Pacific.”

 

“And BP?” Mynx asks.

 

“They intercepted this same message yesterday morning on the wireless and passed it on to us,” Lee explains. “But they’re busy – and they say this is an American affair.”

 

Note: the British have cut all of Germany’s undersea communication cables, so it must rely on radio to send and receive messages beyond its borders. The Y-Station at Beeston Bump plucked this encrypted message from the airwaves on Sunday when the Foreign Ministry broadcast it in Morse code from their powerful transmitter in Berlin. The German Embassy in neutral Portugal received the message then relayed it by commercial telegraph to Ambassador Thomsen in Washington, DC. The FBI intercepted it at this point, as they routinely monitor all incoming foreign cable communications. They passed it on to US military intelligence, which forwarded it to SIS for action.

 

Duncan leaves the mysterious message with us. Mynx and I are both experienced cryptologists, though I’m a bit rusty. As we study it, Mynx makes notes on her steno pad.

 

“Seems strange that they’ve left the words and sentence structure intact,” she observes.

 

“Unless it’s a clever trick,” I note, “to throw us off track.”

 

“I’m seeing the same ‘words’ more than once,” she jots down another note.

 

“You’re right!” I see them now. “OYI, CE, GL … and can I see other letter patterns repeated within the larger words!”

 

RKCYNVAF RIRELGUVAT!

The Ribbentrop Telegram

 

“Seems impossible,” Mynx observes, “that a high-level diplomat would use such a simple encryption.”

 

“Looks like Duncan had a hunch,” I pull another sheet from the folder. “Here’s a letter frequency chart for the message.”

 

PBZCNER!

 

“… Seems to support what I’m thinking,” she notes.

 

“Let’s get started,” I grab a pencil. “This won’t take long,” I hope.

 

Mynx pulls a large easel-mounted flip chart from the corner and we attack the cipher in much the same way you’d solve a cryptogram from the Sunday newspaper. Within the hour the task is finished. We both stare in disbelief at the plain text message we’ve extracted.

Admiral Canaris is skimming the morning intelligence digest when his deputy, Hans Oster, bursts through the door without knocking. Canaris waits for Oster to speak. “Must be important news,” he thinks.

 

“Admiral!” Oster barely contains his excitement. “Did you look at the note that Miss Gruner gave you last night?”

 

“No,” Canaris replies. “I already know what’s in it. That’s why I gave it to you to.”

“Take a look!” Oster hands the note back to the Admiral.

 

Canaris unfolds the faintly perfumed notepaper and stares at the clean, unadorned script for a moment. A faint smile spreads slowly across his deeply creased face.

 

“She did it, Hans.” The Admiral looks up. “She did what I asked of her.” Oster is grinning broadly.

 

“Lillian omitted the second cipher,” Canaris continues, “the superencryption that would have protected Ribbentrop’s message from the Brits and Yankees. Now Hitler is stripped naked for all the world to see.”

 

“Think of it, Admiral.” Oster sits on the edge of the desk, her note in hand. “With her simple ‘mistake,’ Miss Gruner has sabotaged the Fuehrer’s grand plan of world domination.”

 

“An innocent mistake,” Canaris agrees, “but a mistake that required much courage to commit.”

“Good work, kids!” Duncan Lee studies the message we’ve just decrypted. “I’m sure FDR will be very interested in this!”

 

“Got your bags packed?” We both nod. “Good! I’ve got a plane waiting to fly you to Fort Campbell. From there you drive to White House, Tennessee and snatch that gold from right under their noses!”

 

“When do we leave?” Mynx asks. I already know.

 

“How does now sound?” Duncan opens the door. Our friend the sergeant is standing in the hall. He motions toward his Jeep, idling outside the front door.

 

“Wait a minute, Duncan!” I’m confused. “What are we supposed to do when we get there?”

 

“That’s right,” Mynx joins in. “We don’t have enough info to find the gold.”

 

“Just go!” Duncan pushes us out the door. “Call me when you get there. I should have more news for you then.”

“That would be great!” I reply. “The name is St. Clair. We don’t have reservations.”

 

“Biff St. Clair?” the clerk pulls an envelope from his ‘Guest’ mailbox. “This came in from the telegraph office just about an hour ago.”

 

He hands me a Western Union envelope. In our room, I tear it open and unfold a telegram on the small writing desk. We examine the new message closely.

“Looks pretty similar to the Ribbentrop cipher,” Mynx suggests.

 

“Especially the first message,” I agree. “Do you still have the key we made?”

 

“It’s in my purse,” she starts digging. “In… here … somewhere – here it is!”

 

We discover that the second message has a different key, but this is a minor inconvenience. We soon decipher both messages and find that they contain the information we need to solve this mystery – most of the information, that is. We still have to do some old-fashioned gumshoe detective work to locate the hidden cache of gold.

 

“Mynx,” I observe. “These must be the directions that were recovered from the captured Abwehr spies.”

 

“Of course they are, silly!” I look at Mynx, but she’s not smiling. “You realize, Biff, that we have to find the secret cache and snatch the gold before someone else comes looking for it.”

 

“This could be dangerous.” I pat my trusty Walther P38, lodged securely in its shoulder holster. Mynx carries a tiny 22-caliber revolver in her purse.

 

“We better get started,” Mynx whispers. “NOW!”

 

“You’re right,” I agree. “Every minute counts!”

 

“It will be completely dark in a few minutes,” Mynx peers through a crack in the blinds. “Let’s change into our field clothes and head out.”

 

My ‘spy uniform’ consists of black wool chinos, turtleneck sweater and stocking cap. A little charcoal on the face and I’m practically invisible at night. I watch as Mynx slips into her black form-fitting jumpsuit. It accentuates her slinky feline physique. I love this job.

 

“Quit salivating!” she snaps. “Let’s go!”

 

“Right!” I concur. “We can sneak down the back stairs and out the kitchen door.”

 

UHOON! UHOON! ZR YVXR!!

 

THE MISSION

 

If you’ve managed to come this far with Biff and Mynx, dear reader, we must assume that you’re planning to solve this little conundrum. Your mission, should you elect to continue, is quite simple. You must complete the work begun by Biff and Mynx. That is:

 

  • Decipher both telegrams
  • Find the hidden cache
  • Recover the gold before it falls into the wrong hands

 

The Ribbentrop telegram describes Hitler’s secret plan to ‘neutralize’ the U.S. military and keep America out of his war in Europe. In it you’ll also discover why dozens of Abwehr agents are hiding gold coins at White House, Tennessee as part of this plan. Duncan Lee’s telegram contains the instructions found on two German spies when they are captured on American soil. These messages describe the exact location of the hidden gold.

 

Once you’ve deciphered the Ribbentrop telegram, you’ll understand why time is short. You must not procrastinate, but instead proceed immediately to recover the hidden gold. You’ll most likely encounter Abwehr spies and other unsavory characters at the cache site. They’ll be armed and extremely dangerous. Be sure to carry a pistol. A couple of concussion grenades might come in handy. You may have a real fight on your hands, so come prepared.

 

NEZRQ NAQ QNATREBHF!

 

BACKGROUND: Joachim von Ribbentrop

 

Ulrich Friedrich Wilhelm Joachim von Ribbentrop (April 30, 1893 – October 16, 1946) was Foreign Minister of Germany from 1938 until 1945. He was hanged for war crimes after the Nuremberg trials.

 

Ribbentrop is a fervent Nazi who successfully navigated the political patronage system to advance to his current position of Foreign Minister. Prior to that, he traveled across Europe for many years as a salesman of champagne, wines and spirits. As such, he speaks fluent French, English and Italian. He projects a polished demeanor that is easily mistaken for sophistication. But Ribbentrop is, in fact, an archetypical Nazi thug and arguably the most feebleminded officer in Hitler’s administration.

 

The Foreign Minister has access to Enigma encryption, a method that the British have been unable to crack, despite a massive effort. The Enigma machine is cumbersome, however, and he, like other top Nazi officials, prefers his own simpler system for private, off-the-record communications. Only Ribbentrop is so foolish to use his for official correspondence of this magnitude.

 

The logical source for a personal cipher is the Abwehr spymaster, Wilhelm Canaris. It is, in fact, almost a cottage industry for him. He happily provides these ‘boutique’ ciphers not only for Ribbentrop, but also for Goering, Heinrich Himmler, Joseph Goebbels and other top Nazi henchmen. They payoff for Canaris – he can decipher their private exchanges and keep a close eye on the darkest side of the National Socialist movement.

BACKGROUND: WILHELM CANARIS

 

Wilhelm Franz Canaris (January 1, 1887 – April 9, 1945) was a German admiral and head of the Abwehr, the German military intelligence service, from 1935 to 1944.

 

His long career in espionage dates to World War I, where he served as an intelligence officer in the German Imperial Navy and survived several deadly encounters with MI6, the British secret intelligence service.

 

Though never a party member, Canaris originally supported Hitler’s National Socialist movement, as the best organization to fight communism and revive Germany as a nation. By 1938, however, he realized Hitler's policies would bring catastrophe to Germany and secretly began to work against the regime. His Prussian demeanor as an officer and a gentleman provides a stark contrast to the thuggish nature of most Nazi leaders.

 

Throughout WWII Canaris conspired with top Wehrmacht generals to kidnap or assassinate Hitler, then negotiate peace with the Allies. The Gestapo had long suspected him of passing military secrets to the British. In early 1944 he was arrested, tried and sentenced to death.

 

 

BACKGROUND: LILLIAN GRUNER

 

What did Lillian do with Ribbentrop’s telegram that threatens to destroy the Third Reich? In a word – superencryption. That is, she failed to superencrypt Ribbentrop’s message before it was broadcast worldwide. Superencryption would have protected Hitler’s devious plan from prying British and American eyes; long enough, at least, for the operation to have a chance for success.

 

She did this on purpose, of course, at the Admiral’s suggestion. Canaris knew that without superencryption British and American intelligence would decipher Ribbentrop’s telegram almost as quickly as would ambassador Thomsen.

BACKGROUND: DUNCAN LEE

 

Who is Duncan Lee? Few people know that the unassuming, intellectual SIS colonel is a direct descendant of General Robert E. Lee, leader of the Confederate Army and to many, a true hero of the American Civil War.

 

Even fewer realize that Duncan is the latest in an unbroken chain of General Lee’s heirs to serve as supreme commander of the Knights of the Golden Circle (KGC), a secret society founded in the 1850s promoting the secession of southern states to form the Confederacy. As such, Duncan Lee may well be considered the leader-in-exile of the long defunct Confederate States of America.

 

What dangerous game is Lee playing in this espionage adventure? Double agent? Triple agent? No one really knows, as his full role in this and other covert projects is, even today, highly classified information. We leave it to the reader to contemplate and decide.

Home again. After successfully foiling Hitler’s harebrained plan, Mynx and I are back at SOE headquarters, preparing for our next assignment. We share my apartment when we are in London, as her loft near Charing Cross has been destroyed by the Luftwaffe night raids.

 

It’s a cold rainy morning. I’m lying in bed, awake. Thinking. Listening. Mynx is curled up beside me, sound asleep. Far away across the field, the tolling of the iron bell calls the faithful to their knees to hear the softly spoken magic spells.

 

Outside my apartment the wooden floor creaks. I freeze, my senses on full alert. A faint scraping sound, then all is quiet. I rise, grab my pistol from the dresser, and creep silently to the foyer. A heavy brown envelope lies on the doormat. Relaxing, I sit at the desk and prepare to translate the familiar handwriting, encrypted in the standard OSS low-security field cipher.

“Here we go again.” Mynx reads over my shoulder, revolver in hand. “At least it should be warmer – I’ll dig out my cargo shorts!

FINAL NOTE

 

Thanks for your patience as I indulge in another literary ego trip across the vast landscape of history. I hope you enjoy the story, or at least don’t find it too painful. Please note that this is a work of historical fiction. That is, the story is set among real events, but is not part of that history. The links provide contextual background. Some may be helpful in cracking the cipher.

 

Read carefully, this story provides clues that can help you deduce the key for each encryption. Ribbentrop’s cipher is, however, both ancient and simple; with a little effort you can crack it even without the key. Mynx and Biff allude to the methods you’ll use. Follow their lead and you’ll soon be in the field, tracking down the hidden gold.

 

My past experience has proven that no matter how I try, there will be errors in this geocache. It’s inevitable. So, if you spot a mistake, or have problems cracking the cipher, or if you just need something clarified, don’t hesitate to contact me. I’ll help you any way I can, short of giving you the final coordinates.
