This is part of the Melanie Travis series. It is the first one I read, and now I'm going back to try to read them all. There are interesting facts about Dog shows. Melanie is a divorced Mom who teaches and shows standard poodles.
Amateur sleuth and single mother Melanie Travis (Watchdog, etc.) and her show poodle, Faith, return in a mundane canine cozy centered around the prestigious Howard Academy in Greenwich, Conn., where Melanie is a full-time tutor. School caretaker Eugene Krebbs, an unsavory school fixture, is found dead in his tool shed, stabbed with a pitchfork. Now, along with juggling Faith's dog shows and dealing with the unexpected arrival in town of her fiancee?'s ex-wife, Melanie finds herself drawn into the investigation. As part of the school's pageant committee, she is charged with searching through the Howard family papers in the school basement, where she discovers a painting and a 60-year-old diary that may hold the clues to Krebbs's death.
