Let me recap the story from the beginning......
Slippage, that's a term that's used to mean leave port in a ship or to lose time. I have certainly done that. Some Slovenian or a Croatian scuffer caught me, red handed almost. I hadn't hurt anyone and all I stole was a box from an empty house. A box long forgotten by its true owners I thought and to whom the contents were precious, I understood. I was paid well to fetch it but my benefactor never saw a return. This investigator heard I was planning the heist and laid in wait for me in secret. He wasn't interested in justice, I don't think, greed was the thing that drove him and still does. I felt him close to me as I left the scene and was able to quickly hide the stash before he closed in. Upset that he hadn't caught me with the box he had me framed as a common thief and I served a spell for the crown. Actually I served some and was given some on the tag that I am wearing now. That is one of the reasons I am not looking for the box myself but hoping you will help me find it. I cannot leave a 5 mile area and I have a curfew after dark. I made a map and have hidden it in a box in some woods but I wont tell you here where to find it. Instead I have devised a number of box locations some of which will give you clues to the maps' location and some that will give you information about the final stash. Read everything carefully and you will have the rewards you deserve. I cant go get the map myself, as the guy that put me away is still watching me like a hawk and hoping I will lead him to the stash. The Palm is a term used by some to indicate that an artefact has been surreptitiously disposed of or concealed to keep its location a mystery.
I know I ran further South West before I came across a major road and blagged a lift towards town. As we crossed the M40 and joined the A41, I managed to throw a canister away containing a number clue to the final hoard location. It was must have been a windy day, because there is no way I could throw the container that far unaided but it is located just under a 1000 feet from the coordinates above besides a footpath and near a bend in a local road.
