The Secret War Spies, Codes and Guerrillas 1939-1945

'As gripping as any spy thriller. Hastings understands, better than any previous historian, that this is as much a story about human nature as it is about the mechanics of code-breaking or spycraft ... he has the novelist's eye for the telling detail ... this book works because Hastings is simply a very fine writer who is not afraid of making judgements ... Hastings's achievement is especially impressive, for he has produced the best single volume yet written on the subject' Lawrence Rees, Sunday Times
