At Risk - Stella Rimington

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.
