1. Mr. Smith asked Karen to stay at his house and watch over his niece Alice while he was away for the night, as he feared riots were possible.
2. That evening, Karen and Alice heard hundreds of angry voices and marching feet outside approaching the house. They realized a group was planning an attack.
3. When a weapon dropped outside and the dog barked, the group resumed marching away. Karen calmly suggested to Alice that it was time for bed, having likely scared off the group.
