What are some examples of dramatic irony in the ransom of the red chief

The dramatic irony is that when Bill sends the little boy a. k. a "Red Chief" home after the 90 miles he supposedly crawled Bill said "i couldn't take it anymore Sam, i sent the boy home, he's gone", but the boy is in the tree behindd him. But bill doesn't know it.

Dramatic irony is when the audience and possibly some of the other characters know something that another character doesn't. This occurs when Bill tries to take the boy home, but Red Chief follows him back to the camp. The reader and Sam can see that the boy is still there as Bill apologizes for giving up the ransom.
