Sins Of Profession (Creatures of Sin #5)
India Harper

Lucas McAndrews loves sex. He wouldn't be a professional gigolo otherwise, although the money doesn't exactly hurt. Operating on the fringes of the law, he's had several occasions to collaborate with the police...sometimes quite willingly. Zone Six is investigating murders involving a local porn studio and needs someone intimately familiar with the sex industry as their inside man. Lucas is happy to help, especially when he meets the department’s newest recruit, the quick-to-blush Detective Mike Finesterre.
Growing attraction soon takes a back seat as Mike, not Lucas, finds himself in the limelight, and catching the eye of porn legend Long John Fenton, a man who will have things his way. Not to mention the fact that there's a murderer on the loose, one who is closer than anyone thinks...
