"When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth."

In this final collection of Sherlock Holmes adventures, the intrepid detective and his faithful companion Dr. Watson examine and solve twelve cases that puzzle clients, baffle the police, and provide readers with the thrill of the chase.

These mysteries involve an illustrious client, a Sussex vampire, the problems of Thor Bridge and of the Lion's Mane, a creeping man, and the three-gabled house. All these cases test the bravery of Dr. Watson and the brilliant mind of Mr. Sherlock Holmes, the greatest detective we have ever known.
