Sleeping with the Enemy expands on long-standing speculation that the iconic designer had a double life and was the lover of a spy, Baron Hans Gunther von Dincklage.
Alleged "revelations" in the biography include that Coco Chanel was a registered German spy (code name: Westminster, borrowed from her friend and lover the Duke of Westminster), knew Hermann Goering and Joseph Goebbels whilst holed at in the Ritz, Paris during the war, and remained a Nazi sympathiser during her lifetime. It's also claimed that Chanel went to Spain on an Abwehr spy mission in exchange for the Nazis releasing her nephew from a military camp.
Sleeping with the Enemy adds to fascination surrounding the iconic fashion designer's personal life. The biography follows the publication of Coco Chanel: An Intimate Life, earlier this month, which claimed that Chanel was a bisexual drug-taker.
Sleeping with the Enemy: Coco Chanel, Nazi Agent is available from 25 August.
