EDMUND: How, my lord, I may be censured, that

to think of. 
CORNWALL: I now perceive, it was not altogether your
brother's evil disposition made him seek his death;
but a provoking merit set a-work by a reprovable
badness in himself.
EDMUND: How malicious is my fortune, that I must 
repent to be just! This is the letter he spoke of,
which approves him an intelligent party to the
advantages of France. O heavens! that this treason
were not, or not I the detector!
CORNWALL: Go with me to the duchess. 
EDMUND: If the matter of this paper be certain, you
have mighty business in hand.
CORNWALL: True or false, it hath made thee earl of
Gloucester. Seek out where thy father is, that he may

in my course of loyalty, though the conflict be sore
between that and my blood.
CORNWALL: I will lay trust upon thee; and thou shalt 
find a dearer father in my love.
