Work trips to “the city of lights” turn dark, as the extent of Mohamed Al Fayed’s power and control becomes clear. Staying in the historic Villa Windsor in Paris should have been a dream come true, but the women are left terrified. This season of World of Secrets is about sexual abuse. And this episode contains some of the most graphic descriptions. For a list of organisations in the UK that can provide support for survivors of sexual abuse, go to bbc.co.uk/actionline. Presented by Cassie Cornish-Trestrail and Shaimaa Khalil, and produced by Neal Razzell and Sally Abrahams. The editor is Matt Willis. It’s a Long Form Audio production for the BBC World Service. Special thanks to series consultant, Keaton Stone, director Erica Gornall and executive producer, Mike Radford.
