"How long did he stand there?"
"I don't know."
"For five minutes, do you think? As long as you could count a hundred?"
"Longer than that."
"Was he young or old, tall or short?"
"He was tall. I think he must have been old, because he wore dark spectacles."
"Did your aunt and Monsieur de Maucroix observe him?"
"No. I asked my aunt when we were in the train if she had seen the gentleman with the funny spectacles, and she said no."
"Did you see him again after he left the waiting-room?"
"No."
