Mr. Brock had first asked himself that awkward question on the Friday afternoon, and he was still trying vainly to answer it, alone in his own room, at one o'clock on the Saturday morning. It was then only the end of May, and the residence of the ladies at Thorpe Ambrose (unless they chose to shorten it of their own accord) would not expire till the middle of June. Even if the repairs of the yacht had been completed (which was not the case), there was no possible pretense for hurrying Allan back to Somersetshire. But one other alternative remained--to leave him where he was. In other words, to leave him, at the turning-point of his life, under the sole influence of a man whom he had first met with as a castaway at a village inn, and who was still, to all practical purposes, a total stranger to him.

In despair of obtaining any better means of enlightenment to guide his decision, Mr. Brock reverted to the impression which Midwinter had produced on his own mind in the familiarity of the cruise.

Young as he was, the ex-usher had evidently lived a varied life.

He could speak of books like a man who had really enjoyed them;he could take his turn at the helm like a sailor who knew his duty; he could cook, and climb the rigging, and lay the cloth for dinner, with an odd delight in the exhibition of his own dexterity. The display of these, and other qualities like them, as his spirits rose with the cruise, had revealed the secret of his attraction for Allan plainly enough. But had all disclosures rested there? Had the man let no chance light in on his character in the rector's presence? Very little; and that little did not set him forth in a morally alluring aspect. His way in the world had lain evidently in doubtful places; familiarity with the small villainies of vagabonds peeped out of him now and then; and, more significant still, he habitually slept the light, suspicious sleep of a man who has been accustomed to close his eyes in doubt of the company under the same roof with him. Down to the very latest moment of the rector's experience of him--down to that present Friday night--his conduct had been persistently secret and unaccountable to the very last. After bringing Mr. Brock's letter to the hotel, he had mysterious disappeared from the house without leaving any message for his companions, and without letting anybody see whether he had or had not received a letter himself. At nightfall he had come back stealthily in the darkness, had been caught on the stairs by Allan, eager to tell him of the change in the rector's plans, had listened to the news without a word of remark! and had ended by sulkily locking himself into his own room. What was there in his favor to set against such revelations of his character as these--against his wandering eyes, his obstinate reserve with the rector, his ominous silence on the subject of family and friends? Little or nothing: the sum of all his merits began and ended with his gratitude to Allan.

Mr. Brock left his seat on the side of the bed, trimmed his candle, and, still lost in his own thoughts, looked out absently at the night. The change of place brought no new ideas with it.

His retrospect over his own past life had amply satisfied him that his present sense of responsibility rested on no merely fanciful grounds, and, having brought him to that point, had left him there, standing at the window, and seeing nothing but the total darkness in his own mind faithfully reflected by the total darkness of the night.

"If I only had a friend to apply to!" thought the rector. "If Icould only find some one to help me in this miserable place!"At the moment when the aspiration crossed his mind, it was suddenly answered by a low knock at the door, and a voice said softly in the passage outside, "Let me come in."After an instant's pause to steady his nerves, Mr. Brock opened the door, and found himself, at one o'clock in the morning, standing face to face on the threshold of his own bedroom with Ozias Midwinter.

"Are you ill?" asked the rector, as soon as his astonishment would allow him to speak.

"I have come here to make a clean breast of it!" was the strange answer. "Will you let me in?"With those words he walked into the room, his eyes on the ground, his lips ashy pale, and his han d holding something hidden behind him.

"I saw the light under your door," he went on, without looking up, and without moving his hand, "and I know the trouble on your mind which is keeping you from your rest. You are going away to-morrow morning, and you don't like leaving Mr. Armadale alone with a stranger like me."Startled as he was, Mr. Brock saw the serious necessity of being plain with a man who had come at that time, and had said those words to him.

"You have guessed right," he answered. "I stand in the place of a father to Allan Armadale, and I am naturally unwilling to leave him, at his age, with a man whom I don't know."Ozias Midwinter took a step forward to the table. His wandering eyes rested on the rector's New Testament, which was one of the objects lying on it.

"You have read that Book, in the years of a long life, to many congregations," he said. "Has it taught you mercy to your miserable fellow-creatures?"Without waiting to be answered, he looked Mr. Brock in the face for the first time, and brought his hidden hand slowly into view.

"Read that," he said; "and, for Christ's sake, pity me when you know who I am."He laid a letter of many pages on the table. It was the letter that Mr. Neal had posted at Wildbad nineteen years since.
