A little mouse and his friend, Gustave, go out to play one afternoon in this darkly comic story about the sadness of losing a friend and the joy of making a new one.
The mouse''s mother has always warned the young friends not to stray too far from home. There is a cat, she says, and it is dangerous to go far away.
But danger doesn''t stop this curious pair, and soon they find themselves face-to-face with their big blue-eyed enemy. In a feat of bravery, Gustave allows his friend the chance to escape - but is gobbled up by the cat in the process. Heartbroken, the little mouse must return home - without his friend - and tell his mother what has happened.
A sweet surprise ending turns this melancholy tale of friendship into a strangely funny book.
