It Walks by Night: A Locked-Room Mystery Featuring Henri Bencolin

A brutal murder has been committed behind locked doors, and every piece of evidence points toward a man who cannot possibly be responsible.

Henri Bencolin, the formidable head of the Paris police, is drawn into a case involving a wealthy duchess, a vanished husband, a grotesque disguise, and a killer who seems able to pass through walls. As fear spreads through the household, Bencolin must separate superstition from deception and uncover the method behind an apparently supernatural crime.

Filled with Gothic menace, psychological tension, and one of John Dickson Carr's earliest impossible mysteries, It Walks by Night introduces readers to a detective whose insight is matched only by the darkness of the crimes he investigates.
