The Scarlet Boy by Arthur Calder-Marshalla

George Grantley has fond memories of his boyhood days spent at Anglesey House with his childhood playmate Charles Scarlet, happy times that came to an end with the Scarlet boy’s tragic death in an accident. Now Anglesey House stands empty, and George thinks it might be just the property his old friend Kit Everness is looking for. Scoffing at rumors that the house is haunted, Kit and his family buy the place and move in. But Charles Scarlet’s death might not have been so accidental after all, and an evil presence that lingers in the house may now have set its sights on Kit’s young daughter Rosa....

Arthur Calder-Marshall’s unusual haunted house story The Scarlet Boy (1961) is a rediscovered supernatural classic whose slow-building dread mounts inexorably until the chilling finale.
