Thanks to their plucky governess, Miss Penelope Lumley, Alexander, Beowulf, and Cassiopeia are much more like children than wolf cubs now. They are accustomed to wearing clothes. They hardly ever howl at the moon. And for the most part, they resist the urge to chase squirrels up trees.

So while Ashton Place is being restored, Penelope, the Ashtons, and the children take up residence in London. As they explore the city, Penelope and the Incorrigibles discover more about themselves as clues about the children’s—and Penelope’s own—mysterious past crop up in the most unexpected ways. . . .
