The Telephone Murders — James Pattinson

The caller on the telephone told Charles Rowan that he would give him a plot for his next novel. The man, who said his name was Hogan, claimed to be a murderer, and he told Rowan where to find the body. From then on, Rowan found himself drawn ever deeper into a waking nightmare - but the bodies were real enough. So who was this killer? Nobody knew, and the police were baffled. But one thing became certain: he was no friend of the writer but a deadly enemy.
