A supernatural thriller by Arthur Conan Doyle. English original edition. An absorbing tale in which Doyle skillfully blends mysterious with the supernatural. Revolving around the paranoid Major Heatherstone, his mounting fears, and three mysterious monks, this tale will captivate you till the very end. Conan Doyle's creation of the logical, cold, calculating Holmes, the "world's first and only consulting detective," sharply contrasted with the paranormal beliefs Conan Doyle addressed in this short novel. Conan Doyle's early interest in both scientifically supportable evidence and certain paranormal phenomena exemplified the complex diametrically opposing beliefs he struggled with throughout his life.
