Something foul has befallen the Bagthorpes! Their holy, healthy cousins are coming to stay. The Bagthorpe children can imagine nothing worse and vow to get rid of their unwanted guests no matter what it takes. And what they think it will take are spiders in their salads and creepy crawlies in their hair, not to mention maggots in their meals and mould on their mattresses. But the Bagthorpe cousins are made of unexpectedly strong stuff. They're not going to be put of quite as easily as that . . .
