A terrorist is targeting Britain. And to make matters worse it’s an “invisible”-- Mi5-speak for someone traveling under a British passport. Virtually impossible to find before it’s too late.
The job falls to Liz Carlyle, the most resourceful counter terror agent in British intelligence. Tracking down this invisible is a challenge like none she has faced before. It will require all her hard-won experience, to say nothing of her intelligence and courage. Drawing on her own years as Britain's highest-ranking spy, Stella Rimington gives us a story that is smart, tautly drawn, and suspenseful from first to last.
