What is the theme of the book Framed By Gordon Korman pls help

Instead Korman prefers smart characters who are never afraid to take action to get whatever it is they want. A recurrent theme of the Swindle series is kids fighting against unfairness by taking matters into their own hands, and this book executes that theme in excellent fashion.

(Not my work)

the symbol of the grandfather's heritage in this excerpt from "the medicine bag,” is the beaded bolo tie.

a bolo tie is a cord fastened around the neck with an ornamental clasp which is worn as a necktie. they have been used by native american tribes such as hopi, navajo, zuni, and puebloans since the mid-20th century.

therefore, the fact that the grandfather is wearing a bolo tie refers to his heritage as native american.

both are bitter over their mistake
