“I did it at once, sir,” said Gregson. “I have had advertisements sent to all the newspapers, and one of my men has gone to the American Exchange, but he has not returned yet.”

“How did you word your inquiries?”

“We simply detailed the circumstances, and said that we should be glad of any information which could help us.”

“You did not ask for particulars on any point which appeared to you to be crucial?”

“I asked about Stangerson.”

“Nothing else? Is there no circumstance on which this whole case appears to hinge? Will you not telegraph again?”

“I have said all I have to say,” said Gregson, in an offended voice.
