Cooper Vengeance (Mills & Boon Intrigue)

Cooper had left no stone unturned when investigating a cold case that hit much too close to home. Or so he'd thought. Thanks to small-town deputy Natalie Becker, new evidence had surfaced that might lead J.D. closer to the truth. But Natalie had a stake in this situation, too, and claimed that joining forces was their best strategy–and their best hope. Problem was, after years of working alone to solve a seemingly unsolvable crime, J.D. found himself distracted by his beautiful partner and her passion for doing the right thing. He'd never met anyone like her and that scared him as much as this unidentifiable madman...until Natalie was made his next target.
