With her debut novel, At Risk, Rimington introduced us to Liz Carlyle--a smart, impassioned MI5 (MI-5) intelligence officer whose talents and ambitions are counterbalanced by an abiding awareness of her job's moral complexities. Here, we are plunged back into her high-stakes, high-tension world. Liz has always been particularly skilled at "assessing people," and when one of her agents reports suspicious meetings taking place at an Islamic bookshop, she trusts her instinct that a terrorist cell is at work. Her boss, Charles Wetherby, Director of Counter-Terrorism, immediately puts a surveillance operation into place. But then Wetherby suddenly takes her off the case: he has received a tip-off that a mole--a "secret asset"--has been planted in British Intelligence. As her colleagues work to avert an impending terrorist strike, Liz is charged with the momentous task of uncovering and exposing the mole before it's too late.--From publisher description
