"I knew it!" Peter whispered, under his breath.

"You interest me," Sogrange replied. "May I know whom I have the honour of addressing?"

"You can call me Burr," the man announced; "Philip Burr. Your names it is not our wish to know."

"I am afraid I do not quite understand," Sogrange said.

"It was scarcely to be expected that you should," Mr. Philip Burr admitted. "All I can tell you is that, in cases like yours, I really prefer not to know with whom I have to deal."

"You speak as though you had business with us," Peter remarked.
