The Grell Mystery: A Mystery and Detective Classic By Frank Froest! AAA+++

A man is found mysteriously murdered in the study of his own house, and the investigation has not proceeded very far before the detectives discover that the body is not what of this man at all, but of some one who looks like him, while he himself has disappeared as completely as if he also had been killed... The author has condensed into his 390 pages an amazing lot of surprises, startling incidents, mysteries, baffling clues, and bewildering situations.
