The Four Musketeers1974

D'Artagnan:
[reciting from memory the letter Richelieu wrote giving Milady de Winter permission to kill Buckingham, d'Artagnan and Constance, as Richelieu reads the actual note which D'Artagnan has handed him] "By my order and for the good of the state, the bearer has done what has been done."

Cardinal Richelieu:
Hm. One should be careful what one writes... [he tears up the note] and to whom one gives it. I must bear those rules in mind.
