  • The best espionage novel you've ever read

    Huffington Post
  • There is much to relish, from its revival of the sexy spy (this time female) to its mischievous portrayal of Putin

    John Dugdale, The Sunday Times
  • As authentic a spy novel as you are ever apt to read, rendered in exciting prose by a master who helped craft the rules by which spying is conducted. A ten-cloak, ten-dagger read

    Washington Times
  • Matthews is the insider's insider. He knows the secrets. And he is also a master storyteller

    Steve Berry, New York Times bestselling author of The Patriot Threat
  • A sequel that's every bit as good as his début . . . Authentic tradecraft, a complex plot that steadily builds tension, and credible heroes and villains on both sides make this a standout
