""Elly Griffiths truly is my Queen of Crime."
Everything has changed for Dr Ruth Galloway. She has a new job, home and partner, and is no longer North Norfolk Police's resident forensic archaeologist. That is, until convicted murderer Ivor March offers to make DCI Nelson a deal.
Nelson was always sure that March killed more women than he was charged with. Now, March has confirmed this and offered to show Nelson where the bodies are buried – but only if Ruth will do the digging.
Curious, but wary, Ruth agrees. March tells Ruth that he killed two more women and that their bodies are buried near the fens, in an area said to be haunted by the Lantern Men, mysterious figures holding lights that lure travellers to their deaths.
Is Ivor March, himself a lantern man, luring Ruth back to Norfolk? What is his plan, and why is she so crucial to it? Are the killings really over?
