trenchard. What on earth made you stay in the firm once you knew?
edward does not answer for a moment.
edward. I thought I might prevent things from getting any worse. I think I did . . well, I should have done that if he'd lived.
trenchard. You knew the risk you were running?
edward. [bowing his head.] Yes.
trenchard, the only one of the three who comprehends, looks at his brother for a moment with something that might almost be admiration. Then he stirs himself.
trenchard. I must be off. Business waiting . . end of term, you know.
booth. Shall I walk to the station with you?
