Jeremy Strong described Ivan's first Casper Candlewacks book as a "funny and engaging debut". This is the triumphant follow-up from the funniest new voice in fiction and once again unsung hero, Casper must save the day.

Most villages have an idiot but Casper's village is full of them. So being bright makes poor Casper something of an outsider.

An infamous cat burglar has struck in the village of Corne-on-the-Kobb, stealing a precious jewelled sword and kidnapping Casper’s baby sister. To make matters worse a gaggle of amateur detectives are on the case, questioning the villagers and getting in the way. Armed only with his wits, an egg-boiling lie-detecting machine and his best friend Lamp, can Casper rescue his sister and save the day?

A side-splittingly funny tale for girls and boys
