The suitcase was badly rusted, and took Erika several attempts, but it yielded and sagged open as she unzipped it. Nothing could prepare her for what she would find inside...

When a battered suitcase containing the dismembered body of a young man washes up on the shore of the river Thames, Detective Erika Foster is shocked. But it's not the first time she's seen such a brutal murder...

Two weeks earlier, the body of a young woman was found dumped in an identical suitcase. What connects the two victims? As Erika and her team set to work, they quickly realise they are on the trail of a serial killer who has already made their next move.

Yet just as Erika starts to make headway with the investigation, she is the target of a violent attack. Forced to recover at home, and with her personal life falling apart, everything is stacked against her, but nothing will stop Erika.

As the body count rises, the case takes an even more twisted turn when the twin daughters of Erika's colleague, Commander Marsh, are suddenly put in terrible jeopardy. The stakes are higher than ever before, but can Erika save the lives of two innocent children before it's too late? She's running out of time and about to make a disturbing discovery...there's more than one killer.

Brilliantly gripping, Cold Blood will have you hooked from the first page and holding your breath to the heart-stopping and shocking ending.
