The Unicorn Murders

This is an ABRIDGED version of the Sir Henry Merrivale   Locked Room mystery The Unicorn Murders.
"Mercury Mysteries are chosen from the hundreds of mysteries published every year — for their pace, literary quality and readability.  Sometimes they are reprinted in full, but more often they are cut to increase the speed of the story — always, of course, with the permission of the author or his publisher.  Cuts were made in this edition."For details see
