What to expect

‘All hail the new Queen of Crime!’ Heat

From the #1 bestseller and Queen of Thrillers comes a gripping suspense perfect for fans of Karin Slaughter and Angela Marsons

No one can protect you from your past…

When a young woman is found strangled in her own bedroom, DS Imogen Grey and DS Adrian Miles are plunged into an investigation to find a twisted serial killer who likes to date his victims before he kills them.

Determined to stop the horrific deaths, Imogen is forced to act as bait – but will she get caught in her own trap? As the search for the killer ramps up, attention falls on the strange new boy in town. Why does he watch his neighbours through the windows? And could the truth be closer to home than any of them realise?
