Keith Mansfield began his career as a writer and publisher working for Robert Maxwell - he never got round to starting a pension. Having studied mathematical physics at Trinity College, Cambridge, his career followed the expected route so now he writes children's fiction and scripts light entertainment programmes for popular television. Along the way, he's published a few books for Oxford University Press, Pearson and the British Film Institute, as well as helping to create The Science of Spying at London's Science Museum.
