Partners in Crime. Jim Nash Adventures, #26

Good boy Friday is taking his masters, Maddie and Jim, out for a walk on his long leash. He veers off course into a dark alley, testing the patience of both. Refusing to come or heel when called, the usually well-behaved dog is forced to disobey. He has discovered what appears to him to be a new friend. He takes it upon himself to inform his masters by nudging the reluctant little yellow ball of fur out from the dark alley and onto the sunny sidewalk.
Jim Nash decides he wants to claim the tiny puppy as his own. Maddie Spence knows better, and is already planning the found dog poster she will produce when she gets the lost little dog home. Both plans go awry when the owner of the puppy appears on their doorstep intent on claiming her dog for herself. When Maddie heads out on an assignment that will take her away from Friday and Jim for an unknown amount of time, dog and man are forced to admit they desperately miss their partner.
To counter his loneliness, Jim is drawn into a relationship that will prove difficult to break off when Maddie returns.
