People are flocking to Ghastly-Gorm Hall from far and wide to compete in Lord Goth's Literary Dog Show.

The esteemed judges are in place and the contestants are all ready to win. Sir Walter Splott is preparing his Lanarkshire Lurcher, Plain Austen is preening her Hampshire Hound and Homily Dickinson and her Yankee Poodle are raring to go. But there's something strange going on at Ghastly-Gorm--mysterious footprints, howls in the night and some suspiciously chewed shoes.

Can Ada, the Attic Club and their new friends the Vicarage sisters (Charlotte, Emily and Anne) work out what's going on before the next full moon?
