Goth Girl and the Ghost of a Mouse, by Chris Riddell

Ada Goth lives with her father in a huge house. Okay, it's more like a mansion. Ghastly-Gorm Hall, in fact. Lord Goth loves his daughter, but thinks children should be heard and not seen. So Ada wears ridiculously clumpy boots so her father can always hear her coming. That is a little strange - but then you should see their house...mansion...castle - whatever!

Ada's friends, William and Emily Cabbage, come to stay one day, and whilst playing with Ada and a ghostly mouse called Ishmael, the gang soon uncover a devious scheme that the gamekeeper, Maltravers, is plotting. With her father not paying her any attention, Ada and her friends must work together to stop Maltravers - but can they do it before it's too late?
