It was not, Santoine was certain, Eaton's presence in the study which had so astounded Blatchford; Wallace and Eaton had passed days together, and Blatchford was accustomed to Eaton's presence in the house. Some one whom Blatchford knew and whose name Santoine also would know and whose presence in the room was so strange and astonishing that Blatchford had tried to prepare Santoine for the announcement, had been there. The man whose name was on Blatchford's tongue, or the companion of that man, had shot Blatchford rather than let Santoine hear the name. The blind man stirred upon his bed. "Do you want something, Mr. Santoine?" the nurse asked. The blind man did not answer. He was beginning to find these events fit themselves together; but they fitted imperfectly as yet. Santoine knew that he lacked the key. Many men could profit by possessing the contents of Santoine's safe and might have shot Blatchford rather than let Santoine know their presence there; it was impossible for Santoine to tell which among these many the man who had been in the study might be. Who Eaton's enemies were was equally unknown to Santoine. But there could be but one man--or at most one small group of men--who could be at the same time Eaton's enemy and Santoine's. To have known who Eaton was would have pointed this man to Santoine. The blind man lay upon his back, his open, sightless eyes unwinking in the intensity of his thought. Gabriel Warden had had an appointment with a young man who had come from Asia and who--Warden had told his wife--he had discovered lately had been greatly wronged. Eaton, under Conductor Connery's questioning, had admitted himself to be that young man; Santoine had verified this and had learned that Eaton was, at least, the young man who had gone to Warden's house that night. But Gabriel Warden had not been allowed to help Eaton; so far from that, he had not even been allowed to meet and talk with Eaton; he had been called out, plainly, to prevent his meeting Eaton, and killed. Eaton disappeared and concealed himself at once after Warden's murder, apparently fearing that he would also be attacked. But Eaton was not a man whom this personal fear would have restrained from coming forward later to tell why Warden had been killed. He had been urged to come forward and promised that others would give him help in Warden's place; still, he had concealed himself. This must mean that others than Warden could not help Eaton; Eaton evidently did not know, or else could not hope to prove, what Warden had discovered. Santoine held this thought in abeyance; he would see later how it checked with the facts.
