Former SAS trooper Dan Shepherd, now a detective in an elite undercover squad, is at the center of these hard-hitting, high-action thrillers from Stephen Leather. Scalpel-sharp suspense and as gritty as the genre gets.

A trawler in the North Sea is in trouble. Its cargo: hundreds of illegal immigrants. Dan Shepherd is sent to lead the rescue operation, and then to investigate the tragedy. What he finds is a counterfeit currency ring and a huge people-trafficking network. But the web reaches wider still, and as his investigation deepens, he discovers that the criminal proceeds are destined to finance the greatest terrorist attack of all.
