Rachel Alexander and Dash Mysteries A Hell of a Dog, Book 3, (Paperback)

Someone is killing off the great dog trainers of the world--and it's up to PI Rachel Alexander and her pit bull, Dash, to collar the murderer

Rachel has just been hired as undercover security at a dog-training symposium at a posh Manhattan hotel. How can the Greenwich Village PI and her pit bull, Dashiell, turn down the hefty fee, plus free room and biscuits at the Ritz? All Rachel has to do is keep the peace among the competitive diva dog trainers who have come with their prize pooches from all corners of the globe.

She and Dash have barely infiltrated the festivities when they find out that one of the trainers, the self-proclaimed guru of a controversial obedience technique, has been electrocuted in his bathtub. The cops are calling it an accident. Until another trainer dies . . . and then another. With suspects including a dog psychic and a behaviorist to the stars, Rachel discovers that it's the humans who need to be housebroken as she and Dash bring a serial killer to heel.

A Hell of a Dogis the 3rd book in the Rachel Alexander and Dash Mysteries, but you may enjoy reading the series in any order.
