LENNOX: Good night—may the king recover soon!
LADY MACBETH: A kind good night to all.
MACBETH: Blood will have blood, they say. The dead will have their revenge. Gravestones have been known to move, and trees to speak, to bring guilty men to justice. The cleverest murderers have been brought forth by the mystical signs made by crows and magpies.
What time is it?
LADY MACBETH: That time when one cannot tell if it is night or morning.
