Gun, with Occasional Music (Harvest Book)

Gumshoe Conrad Metcalf has problems—there's a rabbit in his waiting room and a trigger-happy kangaroo on his tail. Near-future Oakland is a world where evolved animals are members of society, the police monitor citizens by their karma levels, and mind-numbing drugs such as Forgettol and Acceptol are common. Metcalf has been shadowing Celeste, the wife of an affluent doctor, and perhaps he's falling a little in love with her. When the doctor turns up dead, the investigator finds himself caught in a crossfire between agents from the Inquisitor's Office and gangsters who operate out of the back room of a bar called the Fickle Muse. The novel follows Metcalf as he navigates talking animals, competing authorities, and altered social norms while pursuing the truth.
