Murder in the Irish Channel - Greg Herren - Bog

It begins as a simple missing persons case-a young MMA fighter's mother has mysteriously disappeared. But as New Orleans private eye Chanse MacLeod starts digging around, he discovers that she is the leader of a group fighting the powerful Archdiocese of New Orleans over the closing of two churches. As the trail leads from corrupt church officials to powerful real estate developers to the world of cage fighting, Chanse soon realizes there are a lot of powerful people who want to make sure she stays gone-and don't have a problem with getting rid of a pesky gay private eye.
