Puzzle (Answer below)
It was John’s birthday. He was found dead in the games room of his house. Next to his body was a note written in pencil which said “Happy Birthday, John.” The victim had a girlfriend named Molly. The police suspected Molly’s ex-boyfriend as the murderer but they could not find any obvious evidence. While searching the ex-boyfriend’s car, the police found an envelope with Molly’s address written on it. They thought they would compare the handwriting on the envelope and check it against the note.
The forensic technician in charge came in early to work the next day at 7 a.m. He looked out his window which faced east and the sun was rising. He could easily see that the writing on the envelope and note did not match, but it was then that he realized how he could prove that John was likely killed by the ex-boyfriend.
How did he do it?

Answer
The technician’s office faced east, and as the sun was coming in through the window at a low angle it showed some faint shadows on the surface of the envelope. There were words embossed on the paper. They read “Happy Birthday, John.” The ex-boyfriend did not realize that the pencil had left an impression on paper beneath the page written on.
