Book excerpt: Set in China, and ripped from today's headlines, comes a pulse-pounding debut that reinvents the spy thriller for the 21st century. A lone man, Peanut, escapes a labor camp in the dead of night, fleeing across the winter desert of north-west China. Two decades earlier, he was a spy for the British; now Peanut must disappear on Beijing's surveillance-blanketed streets. Desperate and ruthless, he reaches out to his one-time MI6 paymasters via crusading journalist Philip Mangan, offering military secrets in return for extraction. But the secrets prove more valuable than Peanut or Mangan could ever have known. . . and not only to the British.
