When a woman's mutilated body is discovered in a remote countryside property, Detective Kay Hunter is faced with one of the most challenging investigations of her career.

There is nothing in the victim's past to explain her brutal slaying, and no clues as to how her killer got away.

Then a second body is found in a run-down storage facility, the man's remains covered in horrific injuries that bear the hallmarks of prolonged torture.

With two families demanding justice, Kay is under pressure from her superiors to deliver a swift result - but there is no evidence to connect the two victims.

When a third victim is found just a short distance from her own incident room, Kay realises that the killer has no intention of stopping - and they already have their next victim in their sights...

A Deadly Promise is the 13th book in the Detective Kay Hunter series by USA Today bestselling author Rachel Amphlett, and perfect for readers who love fast-paced crime thrillers.
