Much like the classic Sherlock Holmes stories, forensic practioner Dr. Thorndyke\'s exploits are told by his companion Christopher Jervis. This mystery involves two cases that Thorndyke And Jervis get involved with - one a man who is apparently being poisoned, and another who is already dead, but one of his heirs wants to contest the Will. Both cases seem impossible to Jervis, but not to his mentor, Dr. Thorndyke, who sees clues where none seem to exist.
