Macbeth Act 2, Scene 4
Ross and an old man are outside Macbeth's castle discussing how Duncan's own prized horses broke out of their stalls and ate each other a few days before he was murdered. This seemed to foreshadow the king's unnatural death.
Macduff tells Ross that Malcolm and Donalbain probably bribed the guards who murdered the king because the young men have fled the castle. The way that they left suggests guilt, so Macbeth inherits the throne. Macbeth will go to be coronated and Ross will go with him. Macduff, however, is returning to his home in Fife.
