Peter Ackroyd is already well-known as a historian of London. As a kind of adjunct to his mammoth work on the city, here we have a comparatively slender tome on one specific aspect. Underneath the city is a world of its own, of springs, streams, Roman amphitheatres, Victorian sewers, gang hideouts, the creatures which have dwelt in its darkness from rats and eels to monsters and hosts, and last but not least the modern Underground railway system.
