Double Cross by Ben Macintyre

The True Story of the D-Day Spies

A brisk, narrative account of a British World War II counterintelligence operation that turned captured German agents into double agents and used them to feed a web of carefully crafted lies to Berlin; through vivid portraits of personalities such as Garbo, Zigzag and Brutus and the MI5 handlers who managed them, it explains how the Double Cross system and related deceptions convinced the Germans the main 1944 invasion would hit Pas de Calais, diverting attention from Normandy and helping secure the success of D‑Day.
