Introducing...Dangerous MemoriesWhen Sarah watched her 23 year old daughter cycle away from her in Chelsea - a well-off corner of London - she had no idea it would be the last time they’d see each other for 6 years. What would make a loving child from a life of privilege sever ties with friends and family, and disappear? It turns out, Sarah wasn’t alone in losing a daughter. Something strange was happening to other young women, too.And they all had one thing in common: a kind of therapist figure - a woman they were all seeing and sharing their problems, their secrets, their fears with. But it took years for the truth of what was happening behind closed doors to emerge, and the extraordinary things this woman led them to believe.Dangerous Memories is the story of young women who wanted to be healed that became, for us, a story about the healer, and what we risk when we let someone else into our mind, and our memory.

Nikki Allan was 7 years old when she was brutally murdered. Her mother never gave up the hunt to find her killer. David Boyd was a convicted child sex offender who lived three doors down from where Nikki first went missing. So how did it take the police thirty years to find him? This is a story of class prejudice, police corruption and a shocking miscarriage of justice. Hosted on Acast. See acast.com/privacy for more information.

Christopher Allen, an aspiring war reporter, was just 26 when he was shot and killed in South Sudan. At first, it looked like another tragedy of war… a young journalist caught in the crossfire. Until, just hours after his death, his story splintered. The government claimed he wasn’t a journalist at all, but a foreign fighter – a legitimate target. Other evidence suggested he was killed on purpose for being a reporter. In this new series from Tortoise and the team behind Sweet Bobby, Pig Iron is a story about the dark seduction of war, and what really happened to Christopher Allen.  All episodes of Pig Iron are now available for free. Tortoise members and Tortoise+ subscribers on Apple Podcasts can listen to the entire series, ad-free and get access to bonus content, coming soon.
