The American strode angrily towards the door.

“We will see,” he said, determinedly.

Outside a soldier was standing.

“What does this mean?” he asked, in as repressed a tone as he could muster. “Why will you not let my man do as I bid him?”

“I have been ordered by my commanding officer, your Royal Highness,” he answered.

“Ordered to what?” cried Grey.

“Ordered, your Royal Highness, to permit no one to leave the Flag Tower.”

And he saluted again.
