The sunshine of a fair Spring morning fell graciously on London town. Out in Piccadilly its heartening warmth seemed to infuse into traffic and pedestrians alike a novel jauntiness, so that bus drivers jested and even the lips of chauffeurs uncurled into not unkindly smiles. Policemen whistled at their posts-clerks, on their way to work; beggars approached the task of trying to persuade perfect strangers to bear the burden of their maintenance with that optimistic vim which makes all the difference. It was one of those happy mornings. At nine o'clock precisely the door of Number Seven Arundell Street, Leicester Square, opened and a young man stepped out.
