A TALL, pleasantly ugly, youngish sort of man, with very large hands and feet, stood gazing out from an upper window into Little Oakfield Street, which is in the southwestern district of London and lies off the Haymarket, in mid-afternoon of a chilly day in May. Beneath him, and on the opposite side of the street, was an outfitter's shop, and, eyeing the display in the shop window as well as he could at this height and distance, he meditated over buying ties. There was nothing else to do, it appeared, so why not go out and buy ties?
