"Take it from five o'clock the afternoon it happened."

"At what time?"
"No special time. Just when I could get out there. We were going to have dinner and take in a movie. No particular picture; she said we'd pick one out of the paper at dinner."
"Go on."

I walked down the corridor to the Professor's office. His typist was knocking out some letters and there were a couple of students hanging around waiting for him to show up. How about a smoke, Lieutenant?"
