Ben longed for a dog, but he lived in London in a back street, far from any open spaces for exercise and adventure. His grandfather had promised him a dog for his birthday, but the promise was kept twistily; Ben found himself with what seemed a foolish woolwork picture of the smallest dog of the smallest breed in the world. That started something in Ben's mind. What about a dog so small you could see it only with your eyes shut? So begin the strange adventures that end with Ben's finding his own true dog and also the green space, even in London, where they can roam together.
