The Three Taps: A Detective Story Without a Moral
Ronald Knox
If it was murder, how did the murderer get through a door and leave it locked on the inside? If suicide, how did the dead man turn off the gas? A tantalizing mystery well written and not lacking the saving grace. (Ontario Library Review, 1926) (7 hr 1 min)
