When Martha Hale opened the storm door and got a cut of the north wind, she ran back for her big woolen scarf. As she hurriedly wound that round her head, her eye made a scandalized sweep of her kitchen. It was no ordinary thing that called her away—it was probably further from ordinary than anything that had ever happened in Dickson County.

According to my Mentor, Howard Pease, this satisfies 3 requirements:
1. Name your protagonist, your main character.
2. Mention setting, so the reader will immediately know the story’s background: a farm, a city street, a boardinghouse, a hotel, a plane. The time element is often included as an important part of the setting—the time of year, the time of day.
3. Throw out a small hook to catch the reader’s interest.
