"What are you doing over here?"
The young man hesitated.

"You can tell me at least how long you have been in Paris?" Julien interrupted.
"Since the night, Sir Julien, when you came as far as Boulogne."
"May I ask," Julien demanded, "whether I am going to be subject to your espionage?"
The young man whose name was Foster looked blandly at a pile of luggage which was just arriving.
"I am not at liberty, Sir Julien," he said, "to explain my instructions."
Julien shrugged his shoulders.
