A brand new offering from the award-winning author-illustrator of the OTTOLINE books Ada Goth is the only child of Lord Goth. The two of them live together in the enormous Ghastly-Gorm Hall, which is so big that they hardly ever see each other. Lord Goth believes that children should be heard and not seen, so Ada has to wear large clumpy boots around the house so that he can hear her coming. This makes it hard for her to make friends and if she’s honest, she’s rather lonely. Then one day William and Emily Cabbage come to stay at the house, and together with a ghostly mouse called Ishmael, they begin to unravel a dastardly plot that Maltravers, the mysterious indoor gamekeeper, is hatching. Ada and her friends must work together to foil Maltravers before it’s too late!
