"I had no chance to recognize any of them, Mr. Santoine," Eaton replied easily. "I did not see the car coming; I was thrown from my feet; when I got up, it was too far away for me to recognize any one." "Perhaps so; but were you surprised when my daughter recognized one of them as having been on the train with us?" Eaton hesitated, but answered almost immediately: "Your question doesn't exactly fit the case. I thought Miss Santoine had made a mistake." "But you were not surprised; no. What would have been a surprise to you, Eaton, would have been--if you had had a chance to observe the men--to have found that none of them--none of them had been on the train!" Eaton started and felt that he had colored. How much did Santoine know? Had the blind man received, as Eaton feared, some answer to his inquiries which had revealed, or nearly revealed, Eaton's identity? Or was it merely that the attack made on Eaton that morning had given Santoine new light on the events that had happened on the train and particularly--Eaton guessed--on the cipher telegram which Santoine claimed to have translated? Whatever the case might be, Eaton knew that he must conceal from Harriet the effect the blind man's words produced on him. Santoine, of course, could not see these effects; and he had kept his daughter in the room to watch for just such things. Eaton glanced at her; she was watching him and, quite evidently, had seen his discomposure, but she made no comment. As he regained possession of himself, her gaze went back intently to her father. Eaton looked from her back to the blind man, and saw that Santoine was waiting for him to speak. "You assume that, Mr. Santoine," he asserted, "because--" He checked himself and altered his sentence. "Will you tell me why you assume that?" "That that would have surprised you? Yes; that is what I called you in here to tell you." As Santoine waited a moment before going on, Eaton watched him anxiously. The blind man turned himself on his pillows so as to face Eaton more directly; his sightless, motionless eyes told nothing of what was going on in his mind.
