The Thinking Machine

Two women killed in a fourth floor room locked from the inside, with no way in and no way out. The story that invented the detective and the impossible crime at once.

Edgar Allan Poe

A woman is attacked in a sealed chamber and her assailant vanishes from a corridor watched at both ends. A young reporter solves what the police cannot.

Gaston Leroux

A man is found with his throat cut in a bedroom bolted from within. The first full length novel built entirely on the locked room problem.
