Graham Ison Make them pay

Detective Chief Inspector Brock is called out to a burnt-out camper van in Richmond, Surrey.

The van contained two badly burned and very dead bodies.

At first thought to be an unfortunate fire, Brock and his assistant, Detective Sergeant Dave Poole, discover the truth: a double murder has been committed.

As enquiries progress, it becomes clear that the dead couple were on the wrong side of the law, and Brock finds himself investigating not just a double murder, but a financial crime with international implications.
