“And yet you think you know everything.”

The Baron was content to reflect that there was not much that escaped him, and this trifling ignorance was temporary. “I heard,” he said, “that the Princess was in the habit of meeting a man in the chapel, but the identity of the lover was, possibly from motives of delicacy, withheld from me. It was my business to discover who was hidden in the organ.”

“May I ask how you came to suspect my hiding-place?”

“I heard of your being shut up in the organ the previous night.”

“What?” Udo was surprised out of his sullen humour. “I shut up in the organ? Never in my life till to-day.”

The suspicion in his father’s mind that he had been deluded became a certainty. “So,” he exclaimed, without betraying the slightest discomfiture, “then if you speak the truth, my dear Udo, we have both been prettily tricked.”

Udo’s face grew darker. “How tricked?”

The Baron shrugged. “Our Princess has a lover, and you, my boy, are not he.”

“Who is he?” Udo demanded with vicious eagerness.

“Ah, that is what I must know, shall know in a few hours,” his father replied grimly. “He will not enjoy your immunity.”
