Mud, Pap Blossom's loyal dog, has never been in so much trouble before. The school hamster Junior brought home for the weekend is missing, and all the evidence points right to Mud. Considering the circumstances there's only one sensible thing for a dog to do--head under the porch and refuse to come out.
In the meantime, mysteries are cropping up all over. Maggie Blossom and Ralphie find their friend Mad Mary's bag and cane by the side of the road. Since they know she'd never leave them behind without putting up a fight, they are pretty sure something terrible has happened. Vern Blossom and his friend Michael seem to know something about it, but they aren't telling. They think someone is out to kill them. There's rarely a dull moment at the Blossoms', but with the disappearances, a possible kidnapping, and maybe even a murder or two, this weekend promises to be the most exciting ever.
