Black Heart — Anna-Lou Weatherley

When the body of a man is found with his wrists slashed in a London hotel room, it appears at first to be a tragic suicide. But Detective Dan Riley suspects there is more to this case than meets the eye and the pathology report confirms his worst fears -- the victim was poisoned and suddenly Dan is dealing with a murder inquiry.

Then he makes a disturbing discovery, uncovering links between the victim and a woman calling herself Goldilocks on an online dating site. Is she seeking revenge or something more?

Still grieving the devastating loss of his girlfriend and unborn child in a car accident two years ago, Dan throws everything he has into the investigation. Yet just as Dan begins to piece together the clues of this complex case, the body of a woman is found in her bed with identical wounds.

Dan is on the trail of a twisted individual who is much closer than he realises. Can he overcome his own demons and stop the killer before it's too late?

An all-consuming and totally unputdownable read that will have you holding your breath to the very last page. Perfect for fans of Rachel Abbott, Robert Bryndza and Karin Slaughter.
