|| A head injury requires a mandatory health check. That's Naval intelligence's standard procedure. Covert operative David Trevellyan doesn't like procedure. But he goes along to get along. He agrees to a hospital stay and an MRI. Then someone stales his boots. Mistake. Trevellyan decides to keep himself in the hospital until justice is served. His bosses don't share his priorities, so, in trademark fashion, he takes matters into his own hands. The trap he sets slams shut with ruthless efficiency. But Trevellyan finds he's caught more than a thief. He's stumbled into a complex, multi-layered conspiracy designed to cause incalculable diplomatic damage. For the first time in his career Trevellyan must operate in his home territory. He approaches the task with his customary vigor. But between criminals on one side and regulations on the other, he's more isolated than ever. And as a virtual stranger in his own land, with the body-count rising and his time running out, he's soon facing the soul-searching question: Is he doing more harm than good?
