Locked Rooms: The Three Coffins; To Wake the Dead; The Skeleton in the Clock (Mystery Guild Lost Classics Omnibus);

Dust jacket notes: Of all the Golden Age crime writers, John Dickson Carr was considered the greatest practitioner of the impossible-crime mystery - a.k.a. the locked-room murder. What many consider his masterpiece, The Three Coffins, was named as the best locked-room mystery of all time by a panel of Carr's peers. It contains Dr. Gideon Fell's famous locked-room lecture,' which set the gold standard for this genre. In To Wake the Dead, mystery writer Christopher bets a friend that he can swindle a hotel. Instead he finds himself in a hotel room with a murdered woman, who happens to be the wife of his cousin - a cousin who, just two weeks prior, was killed in the exact same manner. Sir Henry Merrivale gets involved with a psychic researcher in The Skeleton in the Clock. And he soon learns it's never a good idea to go ghost hunting in the execution shed of an old prison."
