This "rediscovered" Sherlock Holmes adventure recounts the unique collaboration of Holmes and Sigmund Freud in the solution of a mystery on which the lives of millions may depend.

First discovered and then painstakingly edited and annotated by Nicholas Meyer, The Seven-Per-Cent Solution related the astounding and previously unknown collaboration of Sigmund Freud with Sherlock Holmes, as recorded by Holmes's friend and chronicler, Dr. John H. Watson. In addition to its breathtaking account of their collaboration on a case of diabolic conspiracy in which the lives of millions hang in the balance, it reveals such matters as the real identity of the heinous professor Moriarty, the dark secret shared by Sherlock and his brother Mycroft Holmes, and the detective's true whereabouts during the Great Hiatus, when the world believed him to be dead.
