The beasts of Clawstone Castle - Eva Ibbotson

Can two children foil an outrageous criminal plot with the help of some of the funniest and maddest ghosts ever invented?

Clawstone Castle is ancient and famous, but its elderly owners have no money. In its great park live a legendary herd of wild white cattle that have roamed there since the days of the Druids, and now their future is threatened. Rollo and Madlyn come to stay with their uncle and aunt and, with the help of a mysterious recluse in the castle library, they collect an impressive team of phantoms who agree to help them turn Clawstone into a tourist attraction. There's a bloodstained bride, an aristocrat whose chest is permanently gnawed by a rat, a girl who was sawn in half in a circus, a pair of feet without a body, and more. Paying visitors soon pour through the gates. But then a terrible fate befalls the cattle, and the ghosts and the children find themselves facing some very sinister enemies.
