On the muddy banks of a tidal stretch of the Thames, a dog walker finds a bag containing human bones. Are they linked to the discovery, twenty-five years earlier, of three skeletons found in the burnt-out basement of a Chelsea mansion?
Detective Samuel Owusu is tasked with finding out. Meanwhile, in a remote corner of Wales, a woman named Lucy sees a familiar face on the news and realises the past she’s been running from has finally caught up with her.
As secrets from the Chelsea mansion resurface, Rachel, Lucy, and Henry – the survivors of that terrible summer – are drawn back together, each hiding truths that could destroy them all.
