This is the latest in a series about cats who can talk and read, and owners who know it! Joe Grey is one of them and he calls the police when he sees a crime.
He's taking some live mice to a mother cat who can't go hunting and who needs MEAT while she's nursing, according to Dulcie, Joe's companion. As he's carrying the mice he smells blood and sees evidence of a body being dragged in the bottom of an abandoned pool. He delivers the mice, calls the police, returns to the scene, and finds that it has been cleaned up. Someone has returned and hosed down around the pool and in the pool to smooth up the dirt in it. However, the policewoman who comes notices that the hose is dripping, the walk is only partly wet, and looks for evidence. She finds blood spots!
Through the book you follow the murderer as he disposes of the body, (a wild talking cat, Sage, sees him burying it in a drain that is going to be concreted in) and thinks he's safe. He leaves and robs four houses whose owners are in vacation. You learn that he and his wife, the dead woman, make a practice of moving into a nice neighborhood for a couple of years, befriend all the neighbors, exchange house keys to feed pets, wait until the neighbors are on vacation, rob them and their own house of valuables, and leave on a trip they've told everyone about. He is an asthmatic and has left his inhaler somewhere. When he goes back looking for it he sees the cat who watched him bury his wife, panics, and throws a hammer through the window at Sage.
Sage, the wild cat, had talked to one of the 'city' cats and told her what he had seen. It gets reported to Ryan, the contractor who is doing the remodeling, and she digs up the concrete which has just been poured, calls the police before they dig for the body and find it.
The cats, Joe, Dulcie, and Kit, follow through on everything. Their prowess doesn't fail them.
The book is fun to read, and the mystery of who got killed and who did the killing is kept a secret until late in the book. I'm always waiting for the next book in this series.
