Three doors down: a murder, a mother and a thirty year investigation
In May 2023 David Boyd was found guilty of the brutal murder in 1992 of seven year-old Nikki Allan. Sharon Henderson, Nikki’s mother, called for a public inquiry into why it had taken the police so long to find and convict her daughter’s murderer.
When Nikki was murdered, Sharon was a single mother of four living in Wear Garth, a rundown housing estate in Sunderland. David Boyd lived a few floors above Sharon in the same block. He was known to the police. He was the kind of offender who should have been caught.
Three doors down tells the astonishing story of Sharon Henderson’s thirty year campaign to get justice for her daughter’s killing. It shines a light on police behaviour and their treatment of working class women. It’s a personal tale of trauma and resilience in the face of systemic police failure, that couldn’t be more timely.

Introducing...Dangerous Memories
When 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. The first 2 episodes are out now and released weekly. To binge-listen to all 6 episodes ad-free from today, subscribe to Tortoise+ or download the Tortoise app
