Two chilling stories weave into one in Joseph Glass's stunning new novel of suspense.

The testimony of Dr Susan Shader, Chicago PD's forensic psychologist, has condemned to death killer Calvin Wesley Train - his plea of insanity is blown apart by her evidence that he is a very sane manipulator. And this is something that Train will never forget. But Susan is soon onto an even more disturbing case - there has been a series of murders near Chicago's Loop by a killer nicknamed The Undertaker. The victims have been stabbed and are all found in body bags. But there is also one more remarkable clue - there is blood from someone other than the victim in their wounds. As Susan races to catch The Undertaker before he strikes again, a newly released prisoner called Calvin Wesley Train plots to capture Susan . . .
