Bored by the lack of crime in Quietville lately, Jimmy's vampire dog, Abby, has chewed up his mother's entire shoe collection, and so his parents have insisted in enrolling Abby in obedience training, and the longer it goes on the more "normal" (and boring) she becomes--but when mysterious things start happening to Jimmy's lacrosse team, he and his friends (the Crimebiters) realize they need to get Abby back to her crime fighting ways.

Middle schooler Charlie Joe is proud of his success at avoiding reading, but eventually his schemes go too far.

Jimmy Bishop likes crime fighters, vampires, and dogs, and he does not care for his new babysitter, so he is delighted when his new dog, Abby--who sleeps during the day, and grows huge fangs at night--turns out to be a crime-fighting, vampire dog, who also does not like the babysitter.
