See Me, Feel Me, Touch Me, Kill Me by Alina Popescu

Clients lying through their teeth, lives on the line, and family misadventures. Just an ordinary day in the life of a professional sleuth.

There’s nothing private investigator Emmett Naoki wouldn’t do for family. So when a distressed woman shows up at his office, desperate to find her twin sister, he can’t help feeling for her. Which makes it even worse when he starts suspecting her touching story is nothing but a ruse. If he only knew what she’s playing at…
Normally, Emmett would consult with his brother, Tate, or David, his boyfriend and partner at OWL Investigations. Sadly, they’ve both been keeping secrets from him, which makes them totally unreliable.
The darker this case turns and the shadier his loved ones act, the more Emmett fights his nagging need to discover the truth. He’d better decide fast if he wants to keep on digging or if it’s high time he changed careers. Again.
