"You may as well."

"It's yours, sir," he said. Then he added in a low tone: "I'm—I'm sorry, sir."

For answer he suddenly felt a forceful clutch on his arm.

"The Princess has been kidnapped," cried Ruxton, in a voice deep with passionate intensity. "Do you understand? She was waiting at her house there for that message. Nothing but force would have caused her to leave it until she received that message."
