"But I know the man."

"Who is he?"

"I asked his name a few days ago. His name is Woodford Dunne. He is not an officer—a bank clerk, I think, or possibly a traveling salesman. One thing is certain: he was not trailing your man, not trailing any one."

"Our danger may be greater than you imagine."

"Nonsense!"

"I say yes."

"How?"

"Are you dead certain that man Woodford Dunne is not in this club to shadow you?"
