Variation on the Jekyll and Hyde theme of good and evil forces in one man, as John Talbot, sensitive and somewhat priggish writer, devilled throughout his life by his complete antithesis, Tunstall, kills him. But Tunstall's evil genius lives on in Talbot, who grows increasingly like the dead man,until he too finds his retiring little victim. His obsession turns to madness, and Tunstall's widow turns him from murder to suicide. Well done, with more sex than one associates with Walpole. This belongs in the gallery of pathological horror stories, of which his Portrait of a Man with Red Hair was the start. Setting -- coastal town near Polchester.
