"Mary Jeffers?" he asked.
"Yes?"
"Mary, are you a college graduate?"
"Yes. Who is this? Why do you want to know?"
"This is the police. It's very important. Which college did you attend?"

Because of the nature of the time trap, she was unaware of the previous conversation, and her automatic reply to the unfamiliar voice was, "Ogden? You must have the wrong number. I don't know anyone by that name."
"Don't you remember? I went to the University of Delaware with you. I remember you. You have blonde hair and—"
"No. It's brunette."
