Like a good brie, you feel Hermelin will only improve with age.

Grey's work is intricate and stylish, the images often as wordy as the narrative itself.

Grey's pictures are nostalgic, comic, decorative and dramatically composed, and invite budding detectives to pay attention.

It's rare to find such a talented illustrator who can tell a gripping, original tale so effortlessly.

Fans of Grey's work will once again relish the hectic pace of her storytelling, its humour, its intertextual allusions, its typographical playfulness and its general layout.

Mini Grey's extra details and clues in her artwork are always so entertaining and hopefully this is just the beginning for this charming and astute mouse and his detecting friend Emily.

It's full of hilarious tiny details, which our sharp-eyed hero - and clever parents and children - can spot to solve the mysteries.

This is picture book storytelling at its best. Text and illustration perfectly integrated so that the eye moves easily across the page and the attention is held. Every page is carefully designed allowing different perspectives, creating excitement and movement through the juxtaposition of whole page and split page spreads as well as techniques adopted from graphic novel or film. There are not enough picture books that can reach older children. This is one - and it is a delight.

This is an utterly delightful book, packed with quirky text and illustrations and reall unusual.

How can you not want to read this book over and over again? How can you not want to share it with everyone you meet?

Mini Grey is as skilful as ever as she unravels a complex, tragic and very funny story through action-packed illustrations, captions and speech bubbles.

A gentle, entertaining story.
