A killer is hiding in plain sight, like a snake in the long grass...

When Dr Nell Ward stumbles across a woman's body amongst the purple heather on Furze Heath, she was on the lookout for nests of poisonous adders.

But something is lurking out here far more dangerous than vipers.

A cold-blooded killer is on the loose and this is not his first victim. As DI James Clark begins to investigate, a pattern emerges pointing towards this being the work of a serial killer. Every victim shares the same physical characteristics - all of which are a match to Nell herself.

As Nell is pulled into a tightly coiled mystery, she can't help feeling someone is tracking her every move...

Can she unmask the murderer before they strike again?
