Roger Borniche (born 7 June 1919) is a French author and former detective of the Sûreté nationale. Borniche was born in Vineuil-Saint-Firmin, Oise. He started as a singer, but his fledgling musical career was interrupted by the German invasion of 1940. To make a living, he took a job as a store detective. In 1943, he joined the Sûreté nationale as Inspector to avoid being shipped to a forced labour detail. Assigned to hunt the Resistance, he instead helped partisans escape from occupied France. He deserted in 1944, only days before the D-Day invasion. Upon the liberation of France in August, he was reinstated to the Sûreté nationale and assigned to enforce France's abortion laws. The next year, he was transferred to a homicide unit.
