Scrooge McDuck finished counting his three cubic acres of cash in his Money Bin and went to collect his grandnephews from Emily Quackfaster. She had offered to mind the boys for the day at her workplace. Surely they couldn't have got into any trouble.. could they?
Scrooge arrived at the building and suddenly saw a problem. 10 floors with 100 rooms on each floor.. How was he ever going to find them?
He took a minute to think. The most obvious would be Room 598 but that seemed too easy. He could rule out Room 611.. and the boys would never be in Rooms 371 or 648. Room 797 perhaps? Just as he was about to take the lift to Room 797 on the 7th floor, Emily Quackfaster handed him a piece of paper:

"The swines! Up to mischief after all." said Scrooge.
"Yes I tried to keep an eye on them while I was working but one of them hatched a plan" Emily replied.
"Well they aren't that smart.. I know exactly which room they are in."
Scrooge went up the 5th floor feeling rather smug that he had worked out the note. He found the room he was looking for and on it was another piece of paper. "Blast those pesky grandnephews! Well, they won't get the better of me!"

Scrooge McDuck took another moment to think and then headed back to the lift. A minute later he was getting out of the 8th floor and looking for the next room. He could see the next piece of paper on approach and was chuffed the boys hadn't fooled him.

Hah! Easy! Scrooge McDuck said to himself. Off he went back to the lift and this time got off at the 4th floor. He didn't have to walk far at all to spot another note on another door. His heart sank wondering when this charade would be over.

After a little bit of head-scratching, Scrooge worked out the clue and headed for the lift, getting out on the 2nd floor this time. Once he found the right room he was relieved to read this was the last message. It read "τους κανόνες σχετικά με το πώς οι λέξεις αλλάζουν τη μορφή τους και συνδυάζονται με άλλες λέξεις"

Luckily Scrooge McDuck was a classics graduate. He translated it and worked out which room to go to, this time on the 4th floor. Once there he was expecting to find the boys. Instead there was another note... "Given the theme, we'd have thought you would've worked out we've been in Room 26 all along!
An exhausted and humiliated Scrooge headed for the lift once more.. A hunt without treasure at the end was pointless in his eyes and now he had to deal with three gloating grandnephews laughing at him! Oh well, he thought to himself, at least I can count all my money again in the morning.
