About this book

Put on your finest tweed suit and say bonjour to the world’s most famous and fashionable mouse detective: Monsieur Mustard. The pint-sized detective has just returned to his home city of Bath and is hungry for a new mystery to solve. 

So, when Fabio Fangtooth disappears from his restaurant, Monsieur Mustard leaps into action. What follows is a whirlwind adventure filled with clues, red herrings, funny animal characters, action, and more twists than even the twirliest of moustaches. Can the great detective crack the case before it’s too late?

This is a fabulous light-hearted detective story that channels the fussy brilliance of Agatha Christie’s Hercule Poirot, but in mouse form! Monsieur Mustard is a great hero, and readers will love the mix of pomposity and comedy that he brings to the story. 

Charley Rabbit’s text is accessible and is accompanied by plenty of characterful illustrations throughout. There are also comic style panels and full-page images in the book which break up the text even more and make the 240 pages achievable for a wide range of reading abilities.

A great detective comedy for readers of 7 and upwards, look out for more in the Monsieur Mustard series!
