In <em>Macbeth</em> by William Shakespeare<em>, </em>Lady Macbeth is not involved in the plot against Banquo.
Although Lady Macbeth supports the idea of removing Duncan, she is not part of the plan to murder Banquo. <u>She knows about Macbeth's ambition for more power; however, she is not completely aware of how far her husband would go to achieve his goal</u>. Therefore, Lady Macbeth remains "innocent of the knowledge" when it comes to Macbeth's plan to murder Banquo.
