Once a motor-horn blew a solo near at hand, and Pocket half recognised its note; but he did not connect it with quite another set of sounds, which grew but gradually on his ear out of the bowels of the house. Somebody was knocking and ringing at the doctor’s door, not furiously, but with considerable pertinacity. Pocket was thrilled to the marrow just at first, and flew from the open window to the landing outside his door. The house was in perfect darkness, and still as death in the patient intervals between each measured attempt to rouse the inmates without disturbing the street. It came to Pocket that it must be Baumgartner himself, gone out for something without his key; and the boy was about to run down and let him in, when he distinctly heard the retreat of feet down the front steps, and then a chuckle on the next landing as the doctor closed his bedroom door. Who could it have been? Baumgartner’s chuckle suggested the police; but in that case it was the boy upstairs who was going to have the last laugh, though a grim one, and very terribly at his own expense. He could not close an eye for thinking of it, and listening for another knocking and ringing down below. But nothing happened until the doctor returned between five and six, still with his meerschaum pipe, still in his alpaca jacket, but wearing also the goblin hat and cloak of their first meeting, to renew and intensify the animal fear that glued the boy to his bed. “It is a pity,” said Baumgartner, standing at the window which Pocket had left open. “The air is like champagne at this hour, and not a cloud in the sky! It would do you more good than lying there. It is you who are making yourself ill. If I thought you were doing it on purpose ”—and his eyes blazed—“I’d feed you like a fowl!” “It’s so likely that I should do it on purpose,” muttered Pocket, with schoolboy sarcasm. His eyes, however, were purposely closed, and they had missed the old daggers in Baumgartner’s. “You know best,” said the doctor. “But you are missing the morning of your life! Not a cloud in the sky, only the golden rain in my little garden. I suppose you have not learnt what the golden rain is at your public school? You English call it laburnum; but we Germans have more imagination, thank God!” Pocket did not open his eyes again till he had gone; next instant he had the door open too, as the doctor’s step was creaking down the lower flight of stairs. Once more Pocket ventured out upon the landing, not quite to the banisters; he trusted to his ears as before. They told him the doctor had gone into his dark-room. His heart sank. It was only for a moment. The dark-room door shut sharply. The steps came creaking back along the hall, went grating out upon the doorstep. There was another sharp shutting. Food at last!
