Showing Necessary Action (The Precinct: Bachelors in Blue) by Julie Miller

Going undercover to take down murderous gun smugglers is what Duff Watson lives for. Until he tracks the ring to a Missouri farm . . . and meets paramedic Melanie Fiske. Now the KCPD detective has another critical task: Winning over the curvy redhead who tempts him yet who he can’t let himself trust.

Something about the protective ex-soldier makes Melanie believe he can help her find out the truth about her family. And the desire Duff awakens feels like the real thing. But when Melanie’s life is threatened, can she keep trusting—and loving—a man who lives a life of dangerous deception?
