I entered out of curiosity. One of the men rose and said:

“What does monsieur wish?”

“I wish to know what building this is.”

“Nothing more?”

“Why, no.”

“Then would monsieur like me to take him to the Secretary of the Bureau?”

I hesitated, and asked:

“But will not that disturb him?”

“Oh, no, monsieur, he is here to receive those who desire information.”

“Well, lead the way.”
