I have just one week in London, exchanging the harsh Perth winter for the UK’s summer evenings. I am surprised at just how warm it is; the decision to pack shorts pays immediate dividends for this traveller, though not for the locals who must endure the inelegant sight. There’s something comforting about the fact that one is greeted at Heathrow by a giant picture of Moira Cameron, resplendent in her Beefeater uniform.
