XII (Twelve)

When Robin grew up he thought he wanted to be a cavalry officer until everyone else realised that putting him in charge of a tank was a very bad idea. He then became an assistant gravedigger in London. After that he had a career frantically starting business- es (everything from dog-sitting to cigars, tuition to translation)... until finally settling down to write improbable stories to keep his children from killing each other on long car journeys.
