Door with Seven Locks

Dick Martin is about to walk away from Scotland Yard forever. Inheritance secured, bags packed, the quiet life waiting. Then a dying man staggers into his final shift with a whispered warning about a door with seven locks and keys scattered across London and the countryside beyond. What begins as a courtesy investigation becomes a descent into a labyrinth where nothing is coincidental and everything is connected: a stolen library book that isn't a book at all, a missing heir presumed dead for a decade, a mansion that keeps its secrets behind a door no one can open, and a vivisectionist with no regard for the boundaries between life and death. The body count rises. The puzzle deepens. Every clue seems to lead to two more questions. But Dick Martin, that most reluctant of detectives, begins to see the pattern beneath the chaos: a fortune in gold and jewels, a claim to a title and an estate, and a scheme so audacious it would have succeeded if not for one detective who really should have been on a train to the coast. Edgar Wallace was the master of the wildly improbable plot, and "Door with Seven Locks" is him at his most gloriously overcomplicated. If you like your mysteries twisty, your detectives reluctant, and your doors impossible to open, this is exactly what you've been looking for.
