His Partner's Wife: 3 Good Cops (Harlequin Superromance No. 998)

A cop's creed: If your partner dies, take care of his family. John McLean is a single father and a cop -- and he takes all his duties seriously. A year ago, after her husband died, he added Natalie Reed to his list of responsibilities. At first, that just meant helping around the house. Then a body is found in her den...Once he learns the victim's identity -- and his connection with Natalie's husband -- John realizes the safest place for Natalie is with him. He knows it's the honorable thing to do. But even when you're right, it isn't easy to feel good when you're falling in love with your partner's wife.
