When the narrator went on vacation to Cancun with their aunt, their aunt told them a story about what happened in a big house they were currently living in. The elderly owners of the house, who had been married for 65 years, were killed in the basement by three thieves who broke into the house while they were gone. Decades later, when the narrator and their aunt visited the basement, a large blood stain on the floor remained that had never been fully cleaned up, reminding them of the tragic event.
