“Death?” he said turning at last to Rupert. “My lad, there are worse friends.”

When they came to see him, after he had fallen into a chair, his arms thrown forward on the table, they found a gash across his ribs, of which he had not spoken. He had earned it during the encounter with the sentry, before he swam the moat.

“Hard-bitten!” muttered the Governor, with frank pleasure in the man. “Hard-bitten! The Prince is happy in his servants.”

After they had carried the messenger to bed, the Governor drew Rupert apart. “See here, boy,” he said sharply, “your sense of honour is devilish nice, but it needs roughening just now. You volunteered for death? Well, the order is countermanded—or, maybe, death’s waiting for you close outside. Anyway, you go out to-night—at once.”

“I would rather see my duty that way, sir, if I could.”

“Oh, to the deuce with your scruples! You’re young, and think it a fine, happy business to die for the Prince. It’s a braver thing to live for him—through the stark murk of it, lad. Here are your dispatches.”

The Governor, at the heart of him, was glad to feel that this promising youngster, who had shown patience and gallantry in siege, should have his chance of a run for liberty. He hurried him out of the Castle and down to the edge of the moat. The night was thick with sleet and wind, friendly for the enterprise because it stifled sound.

“You can swim?” said the Governor.

“Passably, sir.”

“Then slip in, and play about like a water-rat until you find your chance to land between the sentries. Make your way into the town and hire a horse at the first tavern. They do not know you in Carlisle.”
