Something is rotten in the town of Widget, and Rags-n-Bones knows it's all his fault. Ever since he snitched that avocado from Miss Ascot's pack, things have been going wrong. Armed with a handful of memories he never realized he had, Rags-n-Bones searches for a way to put right whatever he did to Widget in the past. If only he knew what it was! Unfortunately, the only person who seems to have answers is a half-mad youth that only Rags can see.
Widget is also suffering from a ghost infestation that has the townsfolk almost as spooked of outsiders as they are of actual spooks. While Rags-n-Bones seeks answers in the past, Ascot offers the town leaders her service as an exorcist, only to be handed an ultimatum: banish the ghosts or be banished herself!
Who's meddling with Widget? To catch the culprit, Ascot and Rags-n-Bones must match wits with a shifty sorcerer, a prissy ex-governess, and a troublingly attractive captain before the town consigns itself to the graveyard of history.
