Irish Black: Wes O'Brien Private Detective, Book 1 (Unabridged‪)‬

Eddie Sutherland is dead. Normally, Detective Wes O'Brien wouldn't care about another dead drug dealer, but he may just be the man who killed him. Thrown off the force and under investigation, Wes is called upon privately to look into a cheating spouse case. The one thing he wanted to avoid. Only this case turns into a double homicide with Wes the only witness. Diving deeper into the murder, Wes soon finds himself teamed with a mentally unstable bounty hunter, embroiled in crooked politics, and working against the clock to solve the murders before he becomes the killer's next victim.
