"I am merely measuring the chances," he said steadily. "I am satisfied with life as I find it; I do not believe that there is anything wrong with me; I see at least the possibility of death and nothing to be gained by submitting to an operation."

"Then," she said again wearily, "there is no way out."

"But there is! My way, not the one you have thought of. You have stumbled upon a thing which you must forget; that is all. Give me the free swing to finish Jim Galloway, to complete certain other undertakings. Promise me that you will do this; in return I will promise you not to . . . ."

"Not to commit another theft?" She set the matter squarely before him. "Can you promise that, Rod Norton? Could you keep the promise were it once made?"

"Yes."

"No! You could not. You don't understand or you won't understand. You would obey the impulse which would come just as certainly as the sun will rise and set again. So I can neither accept your promise . . . nor give you mine."

"You will tell what you have guessed?"

"Rather what I know! Even if you were my own brother. . . ."
