The Willoughby's—Timothy; his twin brothers, Barnaby A and Barnaby B; and their little sister, Jane—are old-fashioned children who adore old-fashioned adventures. Unfortunately, the Willoughby parents are not very fond of their children, and the truth is that the siblings are not too keen on their parents either.

Little do the Willoughby kids know that their neglectful mother and father are hatching an evil plan to get rid of them! Not to worry—these resourceful adventurers have a few plans of their own. But they have no idea what lies ahead in their quest to rid themselves of their ghastly parents and live happily ever after.

"The tone of this darkly dry pastiche is consistently witty, and it's chock-full of accessible parodic references to...classic children's texts...Lowry crafts a tidy plot."-The Bulletin,starred review
