Another book in the Patel and Pardoe series, two London detectives that are given the more unusual cases that crop up to solve. When there are a series of violent crimes one thing links them. Witnesses say that the perpetrators were not all there, as in their head was missing, or their feet, or they were only half a person; the right half. It's not any easy case to get into as all the forensic evidence is old, as in the weapon is 80 years old and cigarette butts haven't been made since World War 2.

But slowly they work their way into the case and realise they have to become just as violent as the perpetrators they are chasing to be able to solve the case.

There is a lot of horror and bodies in this book but it's an enjoyable read and what one would expect from the author.
