"Yes, I think so, but she will not be out late. Otherwise, she would have taken the latchkey."
"Good. I will call upon her about ten o'clock. What time are you supposed to return?"
"About nine-thirty or ten, but I could go back earlier."
"You must not do that on any account. It might arouse suspicion if you did not stay out till the usual time. Be back by nine-thirty. I will arrive at ten. Mr. Hersheimmer will wait below in a taxi perhaps."
