The Adventure of the Ecoplasmic Man

Magician Daniel Stashower claims he found this unpublished manuscript in the house of a magic expert who once knew Harry Houdini. It's accompanied by a letter from Dr. John H. Watson to Bess Houdini, dated shortly after her husband's death. The evidence starts of flimsy enough: Lestrade consults Holmes to find out if Houdini can reduce his body to ectoplasm- the matter spirits are made out of. He has already escaped from a Scotland Yard prison cell and even switched all the convicts around, and meanwhile, a signifagent, espionage-connected robbery has been pulled off were it appears the villian can walk through walls. Houdini is arrested for the crime, but he makes a dashing exit from gaol, and now he and the master detective must sleuth out who has framed "the ectoplasmic man".
