FRANCIS (takes the letter out of his pocket): You know our correspondent! See! I would give a finger of my right hand might I pronounce him a liar—a base and slanderous liar! Compose yourself! Forgive me if I do not let you read the letter yourself. You cannot, must not, yet know all.
OLD MOOR: All, all, my son. You will but spare me crutches.
FRANCIS (reads): "Leipsic, May 1. Were I not bound by an inviolable promise to conceal nothing from you, not even the smallest particular, that I am able to collect, respecting your brother’s career, never, my dearest friend, should my guiltless pen become an instrument of torture to you."
