“I will give you proof,” she said. “Three days ago Sir Walter Bullivant and Mr Macgillivray told you to come here tonight and to wait here for further instructions. You met them in the little smoking-room at the back of the Rota Club. You were bidden take the name of Cornelius Brand, and turn yourself from a successful general into a pacifist South African engineer. Is that correct?” “Perfectly.” “You have been restless all evening looking for the messenger to give you these instructions. Set your mind at ease. No messenger is coming.

You will have nothing in the world to do except to let the life soak into you, and, as I have said, keep your eyes and ears open.” “But you must give me some clue as to what I should be
