In front of them they heard the policeman's measured step. From the rear came the sounds of a man racing towards them. His hurried tread sounded in the quiet night like the rattle of steam feet rushing along. As they turned, the man passed them. He was panting for breath, and his clothes seemed to have been hurriedly thrown on. His braces were hanging loose, and he was struggling with his coat as he ran, suggesting the idea that he was racing and dressing himself for a wager. He did not notice the faces of the men as he passed them, but Alfred recognised him, and cried, "Why, that's Mr. Gribble!" The next moment Gribble junior was round the corner and out of sight, and the calm footstep of the watchman of the night heralded Mr. Sheldrake's friendly policeman. He touched his hat to Mr. Sheldrake, and while that gentleman held brief conference with him, his slinking hand asserted itself up his coat-sleeve, where it may be said to have lurked, thirsting for Tip. The comedy, which had been so successfully performed once before during the night, having been repeated successfully, the policeman (awaking from another little sleep) leisurely led the way, Alfred being in the rear. As they walked thus in single file, Mr. Sheldrake's thoughts, put into intelligible language, would have read thus: "That was a shrewd conclusion you came to, David, when you heard this young cub's voice, and guessed that it belonged to Lily's brother! A nice young fool he is! But he'll serve your turn, David, with that little nugget--he'll serve your turn. Make the pretty Lily grateful for having befriended her brother, and get the young fool himself quietly in your hands, and the rosy-cheeked apple falls plump into your open mouth, David--plump into your open mouth!" The contemplation of the rosy-cheeked apple falling plump into his mouth was so agreeable, that David Sheldrake smiled frequently, and in a gay and airy manner blew a kiss in the direction of Lily's house. They paused at the side door of a house of entertainment, closed according to the law, and the mystic summons of the policeman gained them admittance. "Let us have a quiet room, and some brandy-and-water," said Mr. Sheldrake to the waiter who had opened the door, and who, with his shirt-sleeves tucked up and his thick bull-neck, looked like a prize-fighter. "Policeman, you'll come in and have a drink?" "No objections, sir." The liquor having been brought, the policeman treated his conscience to "something hot," and departed to pursue his duties, ready at any moment with his slinking hand to prove himself a worthy watchman of the night and a proper guardian of the public peace.
