The frozen body of a man is discovered in a used car yard on the hottest day of the year, his face contorted by fear and pain.

 Detective Kay Hunter and her team are assigned the case, but when they find out who the victim is, their worst fears are realised.

 There is another man missing – but is he a victim, or a killer?

 With time running out and witnesses afraid to talk, Kay is thrust into one of the most challenging investigations of her career to date.
