Harry Houdini visited Aberdeen in July 1909 while on a tour of Europe. As well as performing, he came to Aberdeen to pay homage to his hero John Anderson - The Wizard of the North - who died in 1874. Houdini had his picture taken by Anderson's grave stone which still stands in the rear of St Nicholas Kirk graveyard.
The cache location is midway between the Palace Theatre [Bridge Place] where Houdini performed, and the city harbour. The story goes that there were still a few tickets left for his show and, as a man with a significant ego, Houdini wanted a sell out show, so he staged an impromptu and very public stunt. No official permission had been requested for this stunt and so none was given. After a wee walk around the city he had gathered a large crowd that recognised and followed him to the harbour where he was shackled by his assistant. He jumped into the water only to emerge unharmed a few minutes later, his show sold out a few minutes after he got out of the water.
Sit on this low wall, facing the road under the three trees, the cache is behind you.
