What’s it about?
The story.
When a priceless treasure vanishes from the Hornville Museum and a night guard is found dead behind a locked door, the town of Widdlington needs the world's greatest detective. Enter Montgomery Bonbon: an unusually short gentleman in a shabby raincoat, with a bristling moustache and an accent from somewhere vaguely European. Nobody suspects that beneath the disguise is ten-year-old Bonnie Montgomery, who cracks cases with the help of her ice-cream-van-driving Grampa Banks. Sifting real clues from red herrings, Bonbon must work out how a thief slipped in and out of a sealed room, and unmask a culprit hiding in plain sight. Alasdair Beckett-King serves up a genuinely fair-play whodunit with jokes on every page and Claire Powell's characterful illustrations throughout. Pitched as Knives Out for kids, it's a comedy-mystery that teaches young readers how detective fiction actually works while keeping them laughing to the final reveal.
Fit check
Right for your child?
Where it lands by age
A comedy-mystery that suits confident readers of about 7-11 reading alone, and works beautifully read aloud to 6-9s who enjoy following the clues together. The tone is cosy and bloodless despite the murders, so it stays comfortable for younger or more sensitive readers.

Why they love it.
Why kids love it
Bonnie fools every grown-up in Widdlington by gluing on a moustache and becoming the great Montgomery Bonbon, then out-thinks them all. Spotting the real clues among the red herrings before the reveal feels like cracking the case yourself, and Grampa Banks and his ice-cream van are the perfect sidekick.

- Having a wise mentor
Why parents love it
Beckett-King plays fair: the clues really are all there, so children learn how detective fiction works while they laugh. The prose is sharp and quotable, the pace never sags, and Claire Powell's illustrations keep even hesitant readers turning pages of a satisfyingly meaty mystery.
