From multi-million-selling Joy Ellis, one of Britain's best-loved crime writers, with over twenty number-one bestsellers.

Meet Detective Nikki Galena. She will stop at nothing to avenge her daughter. Under the brooding skies of the Lincolnshire Fens, she pursues the most vicious criminals.

A serial killer on a poisonous mission pushes Nikki and her team to breaking point.

Revellers are flocking into Greenborough for the yearly Dark Greenborough Festival, a three-day event celebrating local folklore, superstition and the darker side of life.

What the public doesn't know is that there has been a warning sent to the police: "Greenborough will be a very dangerous place this year." The anonymous letter ends with the Latin phrase, Mors certa, hora incerta: Death is certain, the hour uncertain.

Detective Nikki and her team soon discover this is no hoax, as people start dying from what appears to be alcohol poisoning. As the deaths get more horrific, Nikki realises they have a serial killer in their midst.

She and her team are in a desperate race against time before more people die.

The Setting

The Lincolnshire Fens: great open skies brood over marshes, farmland, and nature reserves. It is not easy terrain for the Fenland Constabulary to police: with remote Fen villages, dangerous and often misty lanes, and poor telephone coverage. There are still villages where the oldest residents have never set foot outside their own farmland. A visit to the nearest town is a major event. But it has a strange airy beauty to it, and above it all are the biggest skies you've ever seen.

This totally gripping mystery is perfect for fans of L.J. Ross, Angela Marsons, J.D. Kirk, Elly Griffiths and Ann Cleeves.
