Following in the bestselling steps of Robson Strangest series, London is now given the Strangest treatment.Packed with amazing things you didn't know about the capital, such as the fact that it's still forbidden to run, carry an umbrella or whistle in Burlington Arcade. There's a tiny, working jail cell that looks like a fat lamppost, situated at the southeast corner of Trafalgar Square, that still has a direct phone link to Scotland Yard. The entrance to Buckingham Palace that faces down the Mall is actually the back door, not the front.
