He is one of the world's most ruthless terrorists, codenamed Saladin. He plans and executes devastating attacks and then, ghost-like, he disappears.
Ten years ago he blew a plane out of the sky above New York - and now he's killed dozens in a London strike.
But one of the latest victims is related to the acting head of MI5, who knows exactly who she wants on the case: Spider Shepherd.
Dean Martin, a psychologically damaged former Navy SEAL, is the only person in the world who can identify Saladin. But Martin was killed ten years ago - wasn't he?
Shepherd must find Martin and take him back to the killing fields on the Afghanistan-Pakistan border. Revenge on the world's most wanted terrorist is long overdue, and Shepherd is determined to be the one to deliver it . . .
