Shrewsbury by Stanley J. Weyman

That the villain expected nothing so little as to see the man he was preparing to ruin, I can well believe; and equally that the ordeal, sudden and unforeseen, tried even his iron composure. I have heard that after glancing once at the Duke he averted his eyes; and thenceforth looked and addressed himself entirely to the end of the table where the King stood. But, this apart, it could not be denied that he played his part to a marvel. Known to more than one as a ruffling blade about town, who had grown sober but not less dangerous with age and the change of times, he had still saved some rags and tatters of a gentleman's reputation; and he dressed himself accordingly, insomuch that, as he stood beside Sir John, his stern set face, and steadfast bearing, made an impression not unfavourable at the set out.

Nor when bidden by the King to speak and say what he knew, did he fall below the expectations which his appearance had created, though this was probably due in some measure to my lord's self-control, who neither by word nor sign betrayed the astonishment he felt, when a man to whom for years past he had only spoken casually, and once in six months as it were, proceeded to recount with the utmost fullness and particularity every detail of the journey, which, as he said, they two had taken together to Ashford. At what time they started, where they lay, by what road they travelled -- at all Smith was pat. Nor did he stop there; but went on to relate with the same ease and exactness the heads of talk that had passed between Sir John and his companion at the inn.
