All families have secrets. This one died for them.

When D.I. Matthew Denning is called to a house fire in North London, he expects a tragic accident. Instead, he and D.S. Molly Fisher arrive at a scene of unimaginable horror: the bodies of the Galloway family—Brian and Ellie, their adult children Simon and Amber, and nine-year-old grandson Caleb—lying dead in the ruins.

But the fire didn't kill them.

Forensics confirm the family was murdered before the blaze, executed in their own home by an unknown killer who then tried to burn the evidence. What begins as a routine inquiry explodes into a high-stakes hunt for a psychopath who has wiped out three generations in a single night.

Denning and Fisher soon realise that the Galloways were no ordinary family. Their secrets remain tightly guarded, and someone is prepared to spill a lot more blood to keep them that way.

A tense, twist-filled London detective thriller, Blood Family is perfect for fans of Angela Marsons, Mark Billingham and Robert Bryndza.
