Explanation:

One day, Victor gets word that William, his younger brother, was dead. He returns immediately to Geneva (his homeland) to watch over his deceased brother and visits the place where his brother was killed. There, he sees the Creature and soon realizes that she was responsible for Willian's death. The creature after killing Willian saw that Justine, a very cherished servant of the Frankenstein household, was asleep and placed the jewel that was with Willian in Justine incriminating it.

When she arrives at home, she is informed that Justine is accused of the crime, being found with her the jewelry that the boy took before disappearing, and that was not next to the corpse. Even so, Victor is convinced that Justine is innocent, and the real culprit is his creature. But the evidence against her is strong and Justine is sentenced to death and executed for the crime. Victor Frankenstein feels guilty for having created the monster, and the secret and the guilt began to torture him. Similarly, Elizabeth feels very sad to know that Justine was executed for a crime she did not commit.
