Brodie. Yet I must make her understand...!
Mary. I am your true sister, dear. I cannot fail, I will never leave you, I will never blame you. Come! (Goes to embrace.)
Brodie (recoiling). No, don’t touch me, not a finger, not that, anything but that!
Mary. Willie, Willie!
Brodie (taking the bloody dagger from the table). See, do you understand that?
Mary. Ah! What, what is it!
Brodie. Blood. I have killed a man.
Mary. You?...
Brodie. I am a murderer; I was a thief before. Your brother ... the old man’s only son!
Mary. Walter, Walter, come to me!
