Is Lady Macbeth aware that Lord Macbeth killed Macduffs' family. If no, then I need a quote to prove Lord Macbeth did not inform her(if there is one)

Answer 1

I haven't read this play, and apparently others here haven't either.

Here's the best website I've found to help students read Shakespeare's plays:
http://nfs.sparknotes.com/
Click on the title of the play you want, then click on the act and scene. You'll find original Shakespearean language on the left and a modern-day "translation" on the right.

Here are several other really good websites about Shakespeare and his works and his times. Be sure to add ALL THESE to your favorites so you can find them again.
