“You claim, then,” the young man said, “to be still within the circle?”

“Certainly!”

“You are aware that this is a very dangerous claim?”

Mr. Sabin smiled, but he said nothing. Lord Robert hastened to excuse himself.

“I beg your pardon,” he said. “I should have known better than to have used such a word to you. Permit me to take my leave.”

Mr. Sabin rose.

“I thank you, sir,” he said, “for the courteous manner in which you have discharged your mission.”

Lord Robert bowed.

“My good wishes,” he said, “are yours.”
