[first lines] Waldo Lydecker: [narrating off screen] I shall never forget the weekend Laura died. A silver sun burned through the sky like a huge magnifying glass. It was the hottest Sunday in my recollection. I felt as if I were the only human being left in New York. For with Laura's horrible death, I was alone. I, Waldo Lydecker, was the only one who really knew her, and I had just begun to write Laura's story when another of those detectives came to see me. I had him wait. I could watch him through the half-open door. [clock chimes] Waldo Lydecker: I noted that his attention was fixed upon my clock. There was only one other in existence, and that was in Laura's apartment, in the very room where she was murdered.
