Hugh Ritson was content that Greta should think she had been the victim of a delusion. He was not unwilling that she should be tortured by suggestions of the supernatural. If she concluded that Paul had deceived her as to his departure from Newlands, he would not be unlikely to foster the delusion. The one thing of all others which Hugh Ritson was anxious to prevent was that Greta should be led to draw the purely matter-of-fact inference that when she thought she saw Paul she had really seen another man. But that was his own conviction. He was now sure beyond the hope of doubt that there was a man alive who resembled Paul Ritson so closely that he had thrice before, and now once again, been mistaken for him by unsuspecting persons. That other man was to be the living power in his own life, in his brother's life, in his mother's life, in Greta's life. Who was he? Left alone in the court-yard when the trap drove away, Hugh Ritson shuddered and looked round. He had laughed with the easy grace of a man no longer puzzled as he bid Greta good-night, but suspense was gnawing at his heart. He returned hastily to his room, sat down at the table, picked up the paper which Parson Christian had sent him, and read it with eager eyes. He read it and reread it; he seemed to devour it line by line, word by word. When he would have set it down his fingers so trembled that he let it fall, and he rose from his chair with rigid limbs. What he had dreaded he now knew for certainty. He had stumbled into an empty grave. He opened a drawer and took out three copies of certificates that Mr. Bonnithorne had brought him. Selecting the earliest of these in order of date, he set it side by side with the copy of the extract from Parson Christian's diary. By the one--Paul, the son of Grace Ormerod, by her husband Robert Lowther, was born August 14, 1845. By the other--Paul, the reputed son of Grace Ormerod by her husband, Allan Ritson, was an infant still in arms on November 19, 1847. Paul Ritson could not be Paul Lowther. Paul Ritson could not be the half-brother of Greta Lowther. Hugh Ritson fell back as one who had been dealt a blow. For months he had been idly hatching an addled villainy. The revenge that he had promised himself for spurned and outraged love--the revenge that he had named retribution--was but an impotent mockery.
