The Unicorn Murders
Encyclopedia
The Unicorn Murders is a mystery
novel by the American
writer John Dickson Carr
(1906–1977), who published it under the name of Carter Dickson. It is a locked room mystery
(more precisely, it is a subset of that group, an impossible mystery) and features his series detective, Sir Henry Merrivale.
Both Flamande and Gasquet are masters of disguise, and no one knows what either man looks like. Blake, Merrivale and an assorted group of strangers are in an airplane that is forced to land near the Château de l'Ile, where the Comte d'Andrieu is apparently expecting visitors and offers them all his hospitality.
One of the plane's passengers falls to the ground with a hole in his forehead, as if he had been gored by a unicorn, and the area where he fell was under observation by impartial witnesses such that it seems impossible for anyone to have committed the murder.
Sir Henry must sort out the twin problems of who's really who and whodunnit.
