Die Twice: Andrew Grant

Cooler than Bond. Deadlier than Bourne. The second spy thriller in the David Trevellyan series.
Obliged to leave New York City in the aftermath of his previous mission, David Trevellyan is summoned to the British Consulate in Chicago. To the same office where, just a week before, his new handler was attacked and shot by a Royal Navy Intelligence operative gone bad. Assigned the task of finding the rogue agent, and putting an end to his treacherous scheme, Trevellyan soon finds that once again his only hope of saving countless innocence lives lies not within the system, but in his instinctive believe - you're bound to do what's right, whatever the personal cost may be.
