Conspiracy Theory by Elle Keaton

He can't escape his past--or his future. Bitter and weary, homicide detective Niall Hamarsson burns his last bridge, retreating to the only place he's ever called home. But murder beats him there. Sheriff Mat Dempsey is a glass-half-full kind of guy. He returned to the island after his father drowned to take care of his mom. Life is quiet and simple, until Niall Hamarsson's return. Nothing about Niall Hamarsson is simple. Maybe Niall's childhood refuge will allow him the space to re-evaluate his future. Maybe he'll be able to keep the kind, competent sheriff at arm's length. Mat needs Niall to stay away from the investigation, he doesn't want the ex-detective muddying the waters of Hidden Harbor. Niall's not meddling so much as keeping his hand in. The case is a distraction from the unwanted memories that are popping up like weeds after a rainstorm. How long will it take for the two of them to realize they work better together than apart? In more ways than one? The Veiled Intentions series is a dual POV, slow-burn, three-act, romantic suspense about a broody introvert and a somewhat patient Sheriff as they grope their way to a happily ever after.
