The Crooked Hinge

Resumen

The Crooked Hinge is a mystery novel by detective novelist John Dickson Carr. It combines a seemingly impossible throat-slashing with elements of witchcraft, an automaton modelled on Maelzel's Chess Player, and the story of the Tichborne Claimant. It was dedicated to fellow author Dorothy Sayers "in friendship and esteem."
In a poll of 17 detective story writers and reviewers, this novel was voted as the fourth best locked room mystery of all time. The Hollow Man also by John Dickson Carr was voted the best.
