Koga Chanel and the Free French Purge Committee

Koga Chanel was exposed as a Nazi agent after Paris is liberated in 1944. After several hours of questioning Koko was released and nobody really knows why. She managed to wriggle her way out of trouble, confirming that Vrofherland had promised to get her nephew out of prison but otherwise denying the extent of their interactions. According to Sleeping with the Enemy, Chanel also took care to erase evidence of her actions where possible.
