A brilliantly funny young murder mystery from a rising stand-up comedian, podcaster and filmmaker – and exciting new talent in children's fiction.

Many people go their whole lives without noticing anything that is afoot, amiss, or even untoward; without ever experiencing that toe-tingling, stomach-twisting sensation that a mystery is about to unfold. Not Bonnie Montgomery – the world’s best detective. Not that anyone (other than Grampa Banks) has heard of her… But they might have heard of the great Montgomery Bonbon, the well-dressed gentleman detective who (apart from the hat and moustache) looks suspiciously like a 10-year-old girl. Their newest case: solving the mystery surrounding a highly suspicious death at the Hornville Museum. Together they'll interview some dodgy witnesses, scour the scene for clues and – above all – hope no one notices that Bonnie and Montgomery are never in the same room at the same time...
