Brutus finds letters that are written by the Roman people who desire him to act.

In the play "Julius Caesar" by William Shakespeare, Brutus, a Roman senator, finds letters supposedly written by the Roman people. These letters express their desire for him to take action against Julius Caesar, who they believe is becoming too powerful. The letters are actually a manipulation by Cassius, who wants to provoke Brutus into joining a conspiracy to assassinate Caesar. Here are the steps:

1. Brutus discovers letters: Brutus comes across several letters that have been left for him to find. These letters are not addressed from anyone specifically, but they are written as if they are from the Roman citizens.

2. Letters express a desire for action: The letters that Brutus finds contain pleas from the supposed citizens of Rome. They express concern about the growing power of Julius Caesar and hint at the need for someone to take action to prevent him from becoming a tyrant.

3. The real author of the letters: Unbeknownst to Brutus, these letters are not actually from the Roman citizens. They have been planted by Cassius, another Roman senator. Cassius is jealous of Caesar's power and is plotting to kill him. He writes these letters to manipulate Brutus into joining his cause.

4. Brutus is swayed: The letters have the desired effect on Brutus. He is a noble and patriotic man, and the idea that his people need him to act against a potential tyrant moves him. He joins the conspiracy against Caesar, setting the stage for the tragic events that follow.
