After the rooms at 221B Baker Street are set ablaze—and a mutilated corpse is discovered in the wreckage—Dr. John H. Watson is arrested and imprisoned at Coldbath Fields penitentiary. Writing from a cramped and dimly lit cell, Watson describes the mysterious events leading up to his arrest. Someone has been mailing him a series of cryptic warnings. His lifelong friend Sherlock Holmes has vanished in the raging waters of Reichenbach Falls. And Professor Moriarty’s criminal empire is expanding across Europe and throughout America.
Â
In a desperate attempt to clear his good name, Watson has compiled twelve clues that may prove his innocence, including:
Â
    • The front page of a newspaper from Thousand Oaks, California
    • A catalog of Victorian fashions and merchandise
    • An empty matchbook containing cryptic handwritten notes
    • The complete text of “The Final Problem,†Watson’s famous account of the death of Sherlock Holmes
    • Plus a theater ticket, an arrest report, a railroad timetable, and more
Â
All twelve clues have been painstakingly reproduced for this volume, along with the complete text of Watson’s manuscript and specially commissioned illustrations by Homes aficionado Clint Hansen.
