John Dickson Carr lays on the macabre atmosphere again in this follow-up to It Walks by Night, in which Inspector Bencolin attempts to piece together a puzzle involving a disappearing street, a set of gallows which mysteriously reveals itself to a number of figures traipsing through the London fog, and the bizarre suggestion that a kind of fictional bogeyman, Jack Ketch, may be afoot and in the business of wanton execution. An early gem from one of the great writers of the classic crime genre. This edition also includes the rare Inspector Bencolin short story `The Ends of Justice`.
