We thought you might enjoy listening to the latest season of the BBC’s global investigations podcast World of Secrets: Searching for Soldier Dad. In this first episode of the season, we meet Cathy. Cathy is 10 years old when she starts asking questions. Why don’t I have a father? The secret her mum Maggie is forced to reveal changes everything. Years later, when lawyers and a geneticist turn up in their hometown in Kenya to take DNA samples, Maggie hopes they can help her finally learn the truth. In this investigation, we follow as a team of lawyers and a leading geneticist travel to Kenya to help locate the British soldiers who fathered children then vanished. We witness the groundbreaking legal and scientific detective work used to find the missing dads.    What’s at stake is more than the reputation of the British army and the UK’s post-colonial legacy. The mixed-heritage children have in some cases been ostracised by their communities and denied a chance of British citizenship since birth – something which could transform their lives. Searching for Soldier Dad is a BBC Long Form Audio production for the BBC World Service. Listen to the full series, wherever you get your BBC podcasts.
