    Mail on Sunday
  • ‘Compelling new biography… Hemming has done a wonderful espionage job of his own, scouring obscure files to bring long-hidden agents and their exploits to light. It is also a gripping portrait of an era, now long gone, when the establishment could accommodate such extravagant oddness.

    Daily Telegraph
  • Henry Hemming has found a peach of a subject... Full of new material, fresh interpretations and uncompromising integrity... He has managed the great feat of producing a rattling good read that is also a major piece of revisionist history

    Richard Davenport-Hines, Wall Street Journal
  • Hemming has written a very readable, thoughtful and comprehensive account

    Alan Judd, Literary Review
  • I raced through Henry Hemming's book, constantly having to remind myself that it wasn't a work of fiction. It really has everything you'd want from a great espionage story: incredible agents risking their lives; the highest possible stakes, with the safety of the world hanging in the balance; and at its heart a complicated, mercurial spy master in Maxwell Knight spinning an ever more intricate web.

    Matt Charman, Oscar-nominated screenwriter of 'Bridge of Spies'
