The Agent's Redemption (Special Agents at the Altar, Book 4) (Mills & Boon Intrigue)

After six years hunting The Bride Butcher, FBI agent Jared Bell is as determined as ever to find the ruthless murderer. So when the killer strikes again, he’ll stop at nothing to bring closure to the case—and the first victim’s sister, Rebecca Drummond. Including staging an engagement to lure the madman into a trap...

It’s been years since their torrid rendezvous, but as Jared’s fake fiancée, Becca can no longer ignore their attraction. Or the secret she’s been keeping from him. For now, she needs to focus on bringing her sister's killer to justice—and insist on using herself as bait to do it.
