ACT IV Scene 3

Brutus starts reading a book, but the ghost of Julius Caesar appears, causing the flame to dim. Brutus demands to know who has entered the room, and the ghost tells him, "Thy evil spirit, Brutus" . Brutus then asks the ghost why he has come, and is told that the ghost will see him again at Philippi. The ghost leaves, and Brutus immediately wakes up everyone else in the room. He orders Lucius to go back to sleep, and tells Varrus and Claudio to inform Cassius that he should take his army and march ahead.
