Forbidden Waters, published 15th January 2026, Bloomsbury Raven
It starts with the knife.
Found at the bottom of a hidden lake in the Norfolk Broads, covered in blood and heart tissue so fresh the water hasn’t yet washed it all away. What salvage diver Cam Killick has found is a murder weapon from a very recent crime – but how do you solve a murder without a body?
The remoteness of the setting is itself a clue. Only a handful of people know the location of the lake, let alone how to access it. But no sooner have Cam and DS Claire Rogers started working through this ready-made suspect pool than one of them disappears.
The ripples from Cam’s discovery have disturbed a dangerous predator, one who knows the water even better than Cam himself. The question now is what they want – and how many more people will die before Cam can stop them?
A serial killer is on the loose in Norfolk in this breathtaking thriller from ‘the master of the stone-cold twist’, perfect for fans of Elly Griffiths, Peter James and Ann Cleeves.
