He had nearly finished the process when a knock was heard at the door leading into the hall.

Bernard opened it, and his glance rested on Professor Puffer.

“Are you nearly ready to go down to breakfast?” asked the professor.

“Yes, sir.”

Unbidden Puffer entered the room and looked quickly towards the connecting door. He observed that the bureau had been removed. He frowned slightly, but did not refer to the matter.

“Did you sleep well?” he asked.

“Yes, sir,” answered Bernard.

“So did I. I was conscious of nothing until I woke up this morning.”

He glanced at Bernard, to see whether this statement made any impression upon him. He wished to ascertain whether Bernard had been aware of his attempted entrance during the night.

Bernard made no comment.
