After a time, at a hint from old Roger Chillingworth, the friends of Mr. Dimmesdale effected an arrangement by which the two men were lodged in the same house; so that every ebb and flow of the minister's life-tide might pass under the watchful eye of his anxious physician. Old Roger Chillingworth, throughout life, had been calm in temperament, of kindly affections, and ever in the world a pure and upright man. He had begun an investigation, as he imagined, with the severe integrity of a judge, desirous only of truth. But, as he proceeded, a terrible fascination seized the old man within its grip, and never set him free again until he had done all its bidding. He now dug into the poor clergyman's heart, like a miner searching for gold. "This man," the physician would say to himself at times, "pure as they deem him, hath inherited a strong animal nature from his father or his mother. Let us dig a little farther in the direction of this vein." Henceforth Roger Chillingworth became not a spectator only, but a chief actor in the poor minister's inner world. And Mr. Dimmesdale grew to look with unaccountable horror and hatred at the old physician. And still the minister's fame and reputation for holiness increased, even while he was tortured by bodily disease and the black trouble of his soul. More than once Mr. Dimmesdale had gone into the pulpit, with a purpose never to come down until he should have spoken the truth of his life. And ever he put a cheat upon himself by confessing in general terms his exceeding vileness and sinfulness. One night in early May, driven by remorse, and still indulging in the mockery of repentance, the minister sought the scaffold, where Hester Prynne had stood. The town was all asleep. There was no peril of discovery. And yet his vigil was surprised by Hester and her daughter, returning from a death-bed in the town, and presently by Roger Chillingworth himself. "Who is that man?" gasped Mr. Dimmesdale, in terror. "I shiver at him, Hester. Canst thou do nothing for me? I have a nameless horror of the man!" Hester remembered her promise and was silent. "Worthy sir," said the physician, when he had advanced to the foot of the platform, "pious Master Dimmesdale! Can this be you? Come, good sir, I pray you, let me lead you home! You should study less, or these night-whimseys will grow upon you." "I will go home with you," said Mr. Dimmesdale.
