Agent Jack: The True Story of MI5's Secret Nazi Hunter - Softcover

Eye-opening from start to finish. Pacy, original and frequently chilling, Hutton offers a fascinating new take on the story of the Home Front (Henry Hemming, author of M: Maxwell Knight, MI5's Greatest Spymaster)

A gripping book by a talented new spy-writer which illuminates a shocking episode in our wartime history. Fans of Ben Macintyre's books will love this (Tim Shipman)

Robert Hutton's deeply researched, often astounding book describes how a loose network of homegrown fascists plotted to undermine wartime Britain, and explains the ingenious way MI5 attempted to neutralise them ... Hutton includes transcripts of eavesdropped conversations with these fanatics that would make your hair stand on end (Anthony Quinn Guardian)

Robert Hutton has written a well-researched, highly readable account of Roberts's strange undercover life (Ben Macintyre The Times)

Hutton's brilliant detective work uncovers a fascinating, and hitherto untold, story of spies, eccentrics and fanatics (Josh Ireland, author of The Traitors: A True Story of Blood, Betrayal and Deceit)

I have never encountered a stranger or more touching picture of real-life treachery: the exciting and the humdrum, the venality and the idealism, the incompetence and the expertise ... and all the while the cocktail of high-octane subversion and the low-octane muddle of workaday life. Robert Hutton is an ace researcher but, more than that, a keen and kindly student of real people (Matthew Parris)

We think we know the story of the Second World War, in which Britons were unambiguously on the side of good against evil. But along comes Robert Hutton to show us that that narrative, while comforting, isn't exactly true. We had our own fascists here, eager to do all they could to help the Nazi enemy. In this surprising, even shocking book Hutton tells the extraordinary story of Hitler's British friends - and the unlikely man who did so much to stop them. It's a truly compelling tale (Jonathan Freedland)

At a time when antisemitism is once more rearing its ugly head, this fascinating and well-researched book gives us a salutary reminder that Britain is not immune to homegrown fascist treachery (Tony Robinson)

A great book (John Crace Guardian)

In his absorbing biography Agent Jack, an unassuming Cornish bank clerk, Roberts was an unlikely hero, who set up a fifth column, posing as Jack King, a Gestapo handler, to control domestic subversives. This is a story of safe houses, drops and taped conversations, which amply illustrates Roberts' extraordinary courage (Terry Philpot THE TABLET)
