His suspicions hesitated between Oldbuck and Sir Arthur Wardour.

The former had been at no pains to conceal a marked dislike of him--but the latter he had deeply injured; and although he judged that Sir Arthur did not know the extent of his wrongs towards him, yet it was easy to suppose he had gathered enough of the truth to make him desirous of revenge.
Ochiltree had alluded to at least one circumstance which the adept had every reason to suppose was private between Sir Arthur and himself, and therefore must have been learned from the former.

The language of Oldbuck also intimated a conviction of his knavery, which Sir Arthur heard without making any animated defence.

Lastly, the way in which Dousterswivel supposed the Baronet to have exercised his revenge, was not inconsistent with the practice of other countries with which the adept was better acquainted than with those of North Britain.

With him, as with many bad men, to suspect an injury, and to nourish the purpose of revenge, was one and the same movement.
