There's a razor-thin line between adoration and hatred in Philip Caveney's haunting thriller.

Mark Tyler is a bestselling horror writer, and countless readers are awaiting his next novel featuring Black Wolf. When Mark receives a note from an American fan, he unwisely writes straight back. But his friendly gesture provokes a deluge of increasingly strange letters. Clearly the man is an obsessive who identifies much too closely with the novel's violent supernatural hero.

Distracted by personal problems, Mark fails to notice the mounting psychosis of his 'number one' fan. He cannot know that a small US town is already terrorised by a spate of bizarre deaths dubbed 'the wolfman murders'. Nor can he predict that London will soon suffer its own sequence of grisly killings. Will the author fall prey to a monster of his own creation?
