Double Agent Victoire: Mathilde Carré and the Interallié Network

Her acts of treachery were almost unprecedented in the history of intelligence, yet her involvement in the 'Interallié affair' has only warranted a brief mention in the accounts of special operations in France during the Second World War. But what motivated her to betray more than 100 members of the Interallié network, the largest spy network in France? Was she the only guilty party, or were others equally as culpable?

Drawing on material from MI5 files, Double Agent Victoire explores the events that led to her betrayal, who may have 'cast the first stone', and their motivations, as well as how the lives and careers of those involved were affected. It reveals a story full of intrigue, sex, betrayal and double-dealing, involving a rich cast including members of the French Resistance, German Abwehr and British Intelligence.
