A woman was found dead at the bottom of a skyscraper stairwell. Her pockets held a set of keys and a crumpled grocery list. The detective rode the elevator to the 50th floor, stepped out, walked to the stairwell, and arrested the building's night watchman. Why did the detective suspect the watchman immediately?
The elevator
If the woman took the elevator to the 50th floor to use the stairs, she would have needed to press the button. However, the elevator only stops at floors where someone calls it, or more directly, a victim pushed from a high floor wouldn't have keys and a grocery list if they were just visiting; the watchman's job gave him access to push her.
