Be still my heart. Here is one of those once in a blue moon, beautiful, timeless, memorable, heart-warming stories that you’ll want to read over and over and treasure. You might even find a small person to share it with. I’m certain that they would love it too.

Hermelin is a smart little mouse with a flair for typing and a knack for solving mysteries. It is not long before his detective skills have been put to use to help every resident in Offley Street. He may be small in stature, but he is huge
An Educated Rodent, in this case, a literate mouse, solves a number of minor mysteries in a street of houses. There is also a clever child covering the mysteries and their resolutions. A Holmes and Watson coming together. Amusing and fun to spend time on the pictures working it all out.

This is a charming book. Hermelin the mouse lives in the attic of a house in Offley Street. One day he spots some cries for help on the community noticeboard. There's a missing cat, goldfish, reading glasses, handbag and other possessions. He decides to investigate the disappearances and reunite the owners with their treasures. He communicates with them all through typewritten notes and they don't know he's a mouse until he turns up to a party held in his honour. Will they accept him as one of t ...more

Hermelin is a mouse who lives in the attic of Number 33 Offley Street. His attic is filled with books and boxes and a typewriter that Hermelin uses to write with. When Hermelin notices that the Offley Street Notices board is filled with people missing things, he knows just what he has to do. So he starts working as a mouse detective and solving the mysteries of Offley Street. He does this by noticing things and then leaving typed notes for the people to help them find their missing items. Then w ...more
Love this. Sharp-eyed kids will solve the mysteries alongside Hermelin. Detailed illustrations have that sort of Brett Helquist-y old-fashioned detail thing going on, with sweet antiquey collage elements. And Hermelin himself is the most sensitive, intelligent, and stylish mouse since Stuart Little.
Born in a box designed for cheese, Hermelin makes his home in the attic of 33 Offley Street. The residents are very busy individuals, and Hermelin decides to put his wits to work in solving several small mysteries for the human inhabitants of the building. He sees notices seeking lost objects and pets, and proceeds to quickly type out notes informing their owners of their whereabouts. The grateful residents throw a party in his honor, hoping to meet this wonderful detective, but only one of them ...more

After making his home in the attic of an apartment building, Hermelin, a small mystery-solving mouse, notices the building notice board covered with notices of missing items. Hermelin sets out to help return lost items by writing notes to the various apartment tenants, helping to recover a missing bracelet, purse, teddy bear, and more. When the tenants throw a party in the mysterious Hermelin's honor, he's touched, until the attendees scatter in a panic at the sight of a mouse. When Hermelin dis ...more
This book is so cool! I love how the illustrations have tons of details, you could find something new in this book every time you read it. The story is really funny and sweet too. The ending left it open for a sequel which I hope is going to happen.
Skye: "I like how the details on the first pages are clues to help you solve the mysteries." Felix: "I like it because it's a mouse. Mice are sneaky!" Mini Grey is always a hit in our house. Love her illustrations!

I had to read this for a memory test in grade 6. We had to remember like, every picture and sentence.

Why do all stories about a mouse take place in Paris? Lol - and they all have a re-occuring theme - a mouse that helps people out and then they are all appaled by mice and hate them.

I personally don't hate mice. They're just trying to survive in this world like we are.
Hermelin is a rodent that lives on Osprey street and spends all his time observing his neighbors so that when things go missing he is able to solve the case. But there is one resident that may be observing Hermelin! What will he do when he's found out?

I got this one for me because it looked like a fun little mystery book where my nephew and I could talk about all the little bits of writing that were added. He didn't understand what a typewriter is (haha!) he kept asking if it was a computer... S

Really good book, it was really fun to read. I was sad when no one liked him and he felt alone but I am glad though that he found a friend in the end.
Very clever! My children loved solving the mystery by looking at the illustrations.

I really enjoyed reading this book. I was able to really get a feel for life in Hermelin's shoes as he went around town solving crimes and meeting the ones who had deemed him a hero. But the real reason this book is so awesome is that there are a Lot more pieces to the story than those mentioned in the main type. All the pictures of writings or messages explain what is really going on. Unfortunately, the amount of hidden detail in the pictures makes it a difficult book to read in front of a clas ...more

There's so much going on in the illustrations that come into play later in the story- I think it would work better with smaller and older (5, 6 y.o.) audiences. The first group I read to looked a little blank, but once I was more familiar with the story, and modified the text for the next group, it was far more successful. We actually weren't able to finish, but they remembered one week later and really wanted to pick it back up.
Hermelin has some great detective skills that he puts into action on Offley Street helping the apartment neighbors. I picked up this book for my neighborhood unit, and for that it fell short, especially for a picture walk for 1st grade. But, for a super cute story, with great visuals, it is easily a book children will love.
Hermelin sounds like it should be in a set with Madeline and Anatole. Alas the mouse Hermelin is named after a brand of cheese and a glance at the residents of Offley Street, assures that we are in the world of Anglo speakers. But French sounding christian names are not the end of similarities, at least not in the case of Anatole, as both are detailed books featuring quick-witted mice with excellent typing skills attempting to survive, or even flourish, alongside people who scorn their presenc ...more

Mini Grey has been such a clever author/illustrator through the years. In Hermelin, she breaks from her often fractured fairy tales and adventure tales to take on a mystery with Hermelin the mouse detective at the center of the story. In an amazing opening layout, Grey creates all the visual clues a reader needs to help solve what emerges as a series of mysteries on Offley Street. In comes the curious, observant and literate mouse Hermelin who solves them all. His literacy and problem solving sk ...more

Review originally posted on Children's Atheneum

Hermelin is a noticer. He is also a finder. He is also a mouse. The occupants of Offley Street are delighted when their missing items are found, but not so happy to learn that their brilliant detective is a mouse.

Perhaps it was The Great Mouse Detective that has given me a small soft place for detective mouses, but I absolutely loved this story. It was cute, memorable, well-drawn, that can be read over and over again. There was so much going on eac

The people of Offley Street need help! And Hermelin is just the mouse for the job. With his trusty typewriter, he helps all the people solve the little mysteries in their lives. He even helps them rescue Baby McMumbo. All it takes is a keen eye and good communication skills. But when they want to throw a thank you party for Hermelin, things go awry. He's met with the "blood-freezing scream" of MOUSE! and he is forced to flee. He is devastated to find out that they think he's a "pest." But there ...more

A delightful introduction to mystery stories, Hermelin the mouse finds he is quite apt at finding lost things and helping out the people of Offley Street. The tid-bit stories are inviting and great for older picture book readers/listeners but the plenitude of mysteries means they are short and don't allow room for investigation.

Also, the story is not entirely about solving mysteries. When Hermelin is invited to a party in his honor he scares the residents of Offley Stree

Delightful book about a mouse who can read, write, type and solve mysteries!

Hermelin lives in an attic on Offley Street and happens to see a bulletin board where human residents of Offley Street have posted notices of lost things like –

• A missing gold fish
• A diamond bracelet
• A beloved goldfish
• Reading glasses
• A black leather bag containing life savings!

Hermelin thinks to himself: “Great heavens! Just LOOK at all these lost things! These poor people of Offley Street need some HELP!” Hermeli

Hermelin is a mouse that lives on Offley Street and notices that many of her (human) neighbors are missing a variety of things by postings on the community bulletin board. She determines to help them and with the aid of her typewriter guides them to their lost items. They are so grateful they post a message on bulletin board inviting Hermelin to a party in her honor to thank her for helping them. But things don't go quite so well as planned when they see a mouse show up. Very fun story!

Great ill

Hermelin is a mouse. He's a mouse with a talent for typing and noticing details, which makes him a perfect candidate to solve several missing item mysteries that have happened in his apartment complex. The people he's helped are very appreciative, but are they really ready to meet their tiny hero?

A cute detective story that looks like it may be gearing up for a series of books. This book is set up as a feast for the eyes, but may be a challenge to read aloud because of all the disparate text box
