"From the author of the Charlie Joe Jackson series comes the fourth and final book in the humorous illustrated series about a boy whose new dog may or may not be a crime-fighting vampire. The Crimebiters gang got its start with help from my crime-fighting vampire dog, Abby. But now, I'm starting to wonder if she's really a vampire at all. . . That's a mystery I'm going to have to solve on my own. The rest of the Crimebiters are pretty busy with their own stuff. Irwin's been planning an epic birthday party for the ages, Baxter's worrying about his brother enlisting in the army, and Daisy is cartwheeling her way through cheerleading practice (shudder!). There's only one person I can turn to: the best vampire fiction writer that ever lived, Elroy Evans. He's coming to the nearby COM-MIX convention and I have to ask him the question that's threatening to drive a stake through my heart. Can a dog really be a vampire?"
