Act 3: Suspicious Macduff

      In Act 3 Scene 4, Macduff does not make an appearance at Macbeth's dinner party which makes Macbeth feel that he is planning something against him. Since all of the guests have high standings in society and were invited to celebrate Macbeth being king, Macduff's absence is very suspicious. It makes it seem that Macduff does not accept Macbeth as king and is planning to overthrow him. Those suspicions are confirmed later on in Act 3 Scene 6 when Lennox and Lord talk about how Macduff has gone to England to find Malcolm, who is raising an army of 10,000, to bring him back to rule Scotland.
