The Murder Exchange — Simon Kernick

When ex-mercenary Max Iversson accompanies a nightclub owner to an ill-fated rendezvous in a deserted north London industrial estate, it turns out to be not so much a set-up as a bloodbath. Three men have been shot, the briefcase Iversson has been guarding is empty--and he wants to know why.

So begins a hunt for answers that will take him into direct conflict with Detective Sergeant John Gallan--and take both men into very dangerous territory.
