It was seven o'clock when he went back to his house, and let himself in softly with his latchkey. He knew that he had been walking a long time, and that he had seen the sun rise; but what streets or squares he had been walking in he did not know. He crept upstairs to his dressing-room with stealthy footsteps, and made an elaborate toilet. At eight o'clock he was seated at breakfast in the hastily-arranged dining-room, with the newspapers by the side of his cup and saucer. At nine he went into the hall to receive Dr. Jedd and Dr. Doddleson, who arrived almost simultaneously. His carefully-arranged hair and whiskers, his well made unpretentious clothes, his spotless linen, would have done credit to an archbishop. Of all the cares and calculations of his long dreary night there was no trace, except a certain dulness in his eyes, and the dark half-circles below them. CHAPTER IV. COUNTING THE COST. For four days and four nights there were fear and watching in Mr. Sheldon's house; and in all that time the master never quitted it, except stealthily, in the dead of the night, or at early daybreak, to roam in a purposeless manner he knew not where. The doctors came and went--Dr. Doddleson once a day, Dr. Jedd two or three times a day--and every one in villas adjoining and villas opposite, and even in villas round the corner, knew that the stockbroker's stepdaughter lay sick unto death; for the white horses of Dr. Jedd's landau were as the pale horse of the Pale Rider himself, and where they came was danger or death. Ah, thank God! to some they have brought hope and blessing; not always the dread answer, "You have called me in vain." Valentine Hawkehurst came many times in the day, but between him and Mr. Sheldon there could be no safe meeting; and the lover came quietly to the little gate, where a kindly housemaid gave him a little note from Diana Paget. Miss Paget wrote half a dozen little notes of this kind in the course of every day, but she never left her post in the room opposite the sick-chamber. She complained of headache, or of some vague illness which prevented her taking her meals in the dining-room, and Mr. Sheldon was fain to be satisfied with this explanation of her conduct. She was on guard; and the wretched master of the house knew that she was on guard, and that if Ann Woolper could be bought over, or frightened into compliance with his wishes, this girl would still remain, faithful as watchdog, by the door of her friend and companion. He asked himself whether by violent or diplomatic process, he could rid himself of this second watcher; and the answer was in the negative. The circle around him was a circle not to be broken.
