The new bestseller from the Cartier Diamond Dagger winner and author of the bestselling, Darkness and Light and Gone to Ground.

On Valentine's Day, Lynn Kellogg was shot and survived. The teenage girl standing next to her was less fortunate.
Recently promoted to Detective Inspector in the city's Major Crime Unit, Lynn's rescue of a badly-beaten fifteen-year old from eastern Europe links her to an international investigation into people trafficking and gun smuggling, and teams her up with SOCA — the Serious and Organized Crime Agency — for the first time. Just when everything seems to be progressing smoothly, things start to go wrong, leaving Lynn with serious doubts about the integrity of the SOCA officers in charge. And when DI Charlie Resnick rouses himself from near-retirement to lend a hand, he finds he's blocked at every turn.

Finally, it needs the intervention of Jack Kiley, former cop and soccer player turned private eye, before a way can be found through a miasma of murder and betrayal with mortal danger at each and every turn.
