Drury Lane's Last Case

Ellery Queen challenges you to solve these clues to death. A thin envelope-worth a man's life. A shattered display case-whose stolen contents a thief replaced with a strange manuscript. The murder symbol: 3HS wM … the queer cipher found to be an old mark of death. These are but a few of the baffling signs Drury Lane follows down a path of deception and murder to one of the most startling climaxes in mystery fiction.
