From tomorrow, and for a few days thereafter, my wife and I will have a new neighbour here in London.  Since January we’ve been living in a sort of grace and favour flat given to us by old, old friends from our days living in pre-handover Hong Kong. This flat (ours in exchange for paying utilities – it’s as though we won the lottery) is on the western side of Regent’s Park, about a five or six minute walk north of the Baker Street tube.
