This book is about Beebo his friend Mop and the hamster Hector.
The illustrations are wonderful and Beepo is an inventor who does not want to work in the Paris underground. He inherits a house and they all work night and day to restore it.
When it is finished two men tell them they have to leave as the government want to build a block of flats in its place.
They try to battle by scaring the workers away but this fails and they end up climbing into space.
This is one of my favourite books from my childhood and now my young children love it also despite it very travelled and tatty state!
