Dear Mary | 31 May 2018
Q. I work at a desk by a window which looks out on to the street where I live. I am disturbed by the sight of the same Englishman strolling past the window innumerable times per day. I know most of my neighbours and he is not one of them. Who is he? I can’t think of a reasonable way to ask him, nor do I wish to encourage a friendship, but this mystery is beginning to obsess me. — I.D., London W11 A. Put some marketing bumf into an envelope and address it to, for example, ‘John Brown’ with your street name and postcode, but the house number missing.
