The document describes a whodunit mystery involving the murder of a wealthy old man who lived alone. Clues at the scene included unopened mail, Tuesday's newspaper, and spoiled milk bottles, indicating the man had been dead for over two days. The potential suspects are the milk delivery person, newspaper delivery person, neighbor, and mail delivery person. The answer provided is that the newspaper delivery person should be the prime suspect, as the lack of delivered papers on Wednesday and Thursday suggests they knew no one living at the home could read them.
