Eaton had remained in Seattle--or near Seattle--eleven days; apparently he had been able to conceal himself and to escape attack during that time. He had been obliged, however, to reveal himself when he took the train; and as soon as possible a desperate attempt had been made against him, which, through mistake, had struck down Santoine instead of Eaton. This attack had been made under circumstances which, if it had been successful, would have made it improbable that Eaton's murderer could escape. It had not been enough, then, to watch Eaton and await opportunity to attack him; it had been necessary to attack him at once, at any cost. The attack having reached Santoine instead of Eaton, the necessity for immediate attack upon Eaton, apparently, had ceased to exist; those who followed Eaton had thought it enough to watch him and wait for more favorable opportunity. But as soon as it was publicly known that Santoine had not been killed but was getting well, then Eaton had again been openly and daringly attacked. The reason for the desperate chances taken to attack Eaton, then, was that he was near Santoine. Santoine's hands clenched as he recognized this. Eaton had taken the train at Seattle because Santoine was on it; he had done this at great risk to himself. Santoine had told Eaton that there were but four possible reasons why he could have taken the train in the manner he did, and two of those reasons later had been eliminated. The two possibilities which remained were that Eaton had taken the train to inform Santoine of something or to learn something from him. But Eaton had had ample opportunity since to inform Santoine of anything he wished; and he had not only not informed him of anything, but had refused consistently and determinedly to answer any of Santoine's questions. It was to learn something from Santoine, then, that Eaton had taken the train. The blind man turned upon his bed; he was finding that these events fitted together perfectly. He felt certain now that Eaton had gone to Gabriel Warden expecting to get from Warden some information that he needed, and that to prevent Warden's giving him this, Warden had been killed. Then Warden's death had caused Santoine to go to Seattle and take charge of many of Warden's affairs; Eaton had thought that the information which had been in Warden's possession might now be in Santoine's; Eaton, therefore, had followed Santoine onto the train.
