The Robber's Grave (dr. alan twist)

“Paul Halter, a forty-something Frenchman, has donned the mantle of the great John Dickson Carr and has to date produced twenty-nine novels and a collection of short stories, all replete with cunning clues, brain-twisting puzzles, and always fair-play solutions,” says his translator John Pugmire. This is the pseudonymous Halter’s fourth appearance in EQMM.
