Farewell

Original Story

Puzzle situation

There's an important ceremony tomorrow, so I went to bed early. However, around midnight, I faintly heard a crisp sound of metal clashing and then two sets of footsteps, one following the other. When I woke up in the morning, my doorstep was surrounded by people, and there were five corpses on the ground. After uncovering the truth, I sent them to where they belonged.
