Basil is the Sherlock Holmes of the mouse world. He listens in on the cases of the great Sherlock Holmes at 221B Baker Street, to learn at the feet of the master. Then Basil can use that knowledge to solve mysteries among the mice of the world. When danger calls, Basil is on the case with his trusty friend, Dr. Dawson, at his side.

In this book, Dawson and Basil are traveling to find an ancient island. There is a legend that tiny cats were once ruled by benevolent mice on this isolated island. However, evil Ratigan is also on the hunt, and it's a race to see who will discover the lost island first.

I love this story so much! I have always been a fan of the Great Mouse Detective cartoon, so I was delighted to discover that the movie was based on a book series. The writing is charming, the story is exciting, and the mystery is full of wild clues that only Basil can figure out. I also loved the adorable illustrations that bring the characters to life.

This chapter book would be perfect for young readers ages 6-10 who are starting to read on their own, but it is also enjoyable for older children to read. I loved reading it even as an adult!
