Whippersnapper
It’s a cat and mouse game, but the police aren’t the hunter. . .
After the initial success of the classified AI that DI Nikki Ross is secretly testing, there’s high hopes and huge pressure on her new team. But there’s a reason no one in Major Crimes wants the newest case: a John Doe with no ID, no home, no friends, not even a cup in which to collect change. Solving it is impossible enough until, with a second murder, it seems the worst is true. They’re looking at a kill signature.
Suddenly they’re up against not just a serial killer, but one who breaks all the profiling rules, one that’s devolving at an alarming rate, one that’s always one step ahead of them. And they have no clue who is running rings around them.
When Nikki finally understands what her failure means for her, it may already be too late.
Prepare to be gripped by this electrifying crime thriller as Nikki and her team delve into the warped mind of a smart and sadistic killer. Can Nikki stop the Night Killer before they take someone she can’t lose?
Wippersnapper is the second book in the pulse-pounding, tense and twisty police procedural thrillers featuring DI Nikki Ross. If you like surprising settings, a dash of humour, a side of hi-tech classified with a sprinkling of a stubborn dog, you’ll love Karen Guyler’s fast-paced unputdownable series.
