You have condoned a felony and you have aided the escape of a murderer; for I cannot doubt that any money which was taken by James Wilder to aid his accomplice in his flight came from your Grace's purse."

The Duke bowed his assent.

"This is indeed a most serious matter. Even more culpable in my opinion, your Grace, is your attitude towards your younger son. You leave him in this den for three days."

"Under solemn promises——"

"What are promises to such people as these? You have no guarantee that he will not be spirited away again. To humour your guilty elder son you have exposed your innocent younger son to imminent and unnecessary danger. It was a most unjustifiable action."

The proud lord of Holdernesse was not accustomed to be so rated in his own ducal hall. The blood flushed into his high forehead, but his conscience held him dumb.
