It's winter and what better than a ghostly holler-day by the sea? But how are Tabitha Tumbly, Charlie Vapour, Humphrey Bump and the other ghosties to decide between Frighten-on-Sea and Scare-borough?

A postcard from their friend Headless Leslie decides for them: Headless is in Frighten and cannot remember how to get home. He wrote the address on the postcard, then he forgot what the address was. 'I'd lose my head if it wasn't screwed on - which it isn't.'

So the friends descend on Frighten and set off on an exciting ghostie caper, involving a haunted Frighten pier, a mysterious phantom magician, a fun fair and an extremely infuriating Headless Leslie.
