London Under – Peter Ackroyd

In a perfect meeting of author and subject, London’s finest mythologiser goes underground to explore tunnels, sewers, caverns and, most fascinating of all, lost rivers. I probably knew 60 or 70 per cent of the contents here, but I’m happy to read Ackroyd riffing away.

When I next go to London, I plan to visit the Cabinet War Rooms and to locate the grill just off Farringdon Road below which you can still here the Fleet rushing below.
