An antique television set purchased at an estate sale airs a Western program at random times and stops playing at a suspenseful scene. Could Jennet have bought a haunted TV?

At the sale, Jennet rescues Bronwyn, a collie who will be sent to the pound if she isn't sold by the end of the day. Jennet matches Bronwyn with Charlotte Gray, whose subsequent disappearance, along with Bronwyn, leads Jennet into mystery and danger.
