It's Christmas and a serial killer is leaving human remains everywhere in Cambridgeshire. And every time there is the same strange message: #PMK6
The investigation is taken over by detective Washington Poe and Tilly Bradshaw, who are faced with a case where nothing makes sense. Why were some of the victims anesthetized while others had a horrific, agonizing death? Why does their only suspect deny anything they can unquestionably prove and confess things that hadn't even crossed their minds? And why did all the victims take time off from work exactly the same two weeks three years ago?
When an FBI agent gets involved, things take an even darker turn, as she doesn't believe Poe is dealing with a serial killer, but with someone much, much worse: someone who calls himself The Curator.
And nothing will ever be the same again. . .
The Curator, which was shortlisted for the 2021 CWA Gold Dagger, is the third gripping case of detective Washington Poe.
