All this time, Roger Chillingworth was looking at the minister with the grave and intent regard of a physician towards his patient. But, in spite of this outward show, the latter was almost convinced of the old man’s knowledge, or, at least, his confident suspicion, with respect to his own interview with Hester Prynne. The physician knew then, that, in the minister’s regard, he was no longer a trusted friend, but his bitterest enemy. So much being known, it would appear natural that a part of it should be expressed. It is singular, however, how long a time often passes before words embody things; and with what security two persons, who choose to avoid a certain subject, may approach its very verge, and retire without disturbing it. Thus, the minister felt no apprehension that Roger Chillingworth would touch, in express words, upon the real position which they sustained towards one another. Yet did the physician, in his dark way, creep frightfully near the secret.
