“To Grogan’s?”

“Of course.”

“Suppose,” said Barres quietly, “I put myself under your orders and go along with you.”

The strange young man was much diverted:

“In your kind suggestion there appears to be concealed a germ of common sense,” he said. “In which particular service are you employed, sir?”

“And you?” inquired Barres, smilingly.

“I imagine you may have guessed,” said the young man, evidently greatly amused at something or other.

Sheer intuition prompted Barres, and he took a chance.

“Yes, I have ventured to guess that you are an Intelligence Officer in the French service, and secretly on duty in the United States.”

The young man winced but forced a very bland smile.
