Interesting question! In the book The Adventures of Tom Sawyer by Mark Twain, Tom witnesses a very unusual incident.

In the book, Tom and Huck visit a graveyard, which leads to them witnessing a murder. When Tom and Huck first see Dr. Robinson and the men with him (Injun Joe and Potter), Tom and Huck believe that they are devils. However, they soon realize who the individuals are. Subsequently, the boys watch the men.

As the boys watch, Tom and Huck realize that Dr. Robinson is having Injun Joe and Potter unbury a body. After completing their task, Injun Joe begins threatening Dr. Robinson. As the text reveals:

“He [Injun Joe] was threatening the doctor, with his fist in his face, by this time.”

Subsequently, Injun Joe stabs Dr. Robinson. The boys become very alarmed and disturbed. However, they are afraid to say anything due to their fear of Injun Joe. As the text reveals:

“Why, he’d [Injun Joe] kill us some time or other, just as dead sure as we’re a laying here.”

Thus, the boys become disturbed and frightened for Dr. Robinson. Subsequently, this fear eventually incites fear for themselves and they promise not to tell anyone about the events they witnessed at the graveyard.
