A Killer in the Family

A woman uploads her DNA online, searching for her father—but the man who contacts her is Detective Chief Inspector Jonah Sheens. From the acclaimed author of Little Sister, this endlessly twisty crime novel asks: What might a family do to protect or expose a serial killer in its midst?

When the police found the first body, left on a bonfire in the forest, they worried it had the hallmarks of a serial killer.

Now, as they find the second, they know for sure.

Panic about the "Bonfire Killer" quickly spreads through the  sedate suburban area of Southampton. Women are urged not to travel alone at night, and constant vigilance is encouraged among the local residents. But single mom Aisling Cooley has a lot to distract her: two beloved teenage sons and a quest to find her long-lost father, whom she hasn't seen since she was a teenager.

After much debate, she decides to upload her DNA to an ancestry website. When she gets a match she is filled with an anxious excitement that her questions about her father's disappearance from her life might finally be answered.

But to her horror, it's not her father who's found her. It's a detective.

And they say her DNA is a close match for the Bonfire Killer. . . .
