“You have all the precedents on your side,” he admitted at length. “It is your right to prosecute if you choose to do so. Yet I venture to predict that you will be exceedingly sorry if you bring Morgan McNabb to Tennessee and extort his confession--a confession which will necessarily be made public. Besides, there is a much easier way in which you can apprehend his principal.” “Are you willing to indicate the way?” snapped Tregarvon. “Not altogether willing; no. You are at heart a much flintier young man than you appeared to be when we first met, Mr. Tregarvon. It is an inheritance from some one of your Cornish forebears, I imagine. But I have allowed myself to be overpersuaded. You have your car here?” “Yes.” “I shall ask you to drive me. Will you trust me that far?” Tregarvon rose, smiling grimly. “I shall have you for my hostage. If you are about to have me ambushed, I shall make you share my risk. Do we go at once?” Hartridge limped to a closet and found his overcoat, and Tregarvon helped him to put it on. Then he gave the temporary cripple an arm through the laboratory corridor and down the stair. At the steps he lifted Hartridge bodily into the mechanician’s seat of the car. As yet there had been no hint given of their destination, but when he took his place behind the wheel Tregarvon asked for driving directions. “Westward, on the cross-mountain road,” was the brief reply, and no other word was exchanged until the swiftly driven machine was approaching the intersection of the cross-road with the west-brow pike. Then Hartridge said: “To your left,” and Tregarvon had a sudden sinking of the heart. A mile away he could see the lights of Westwood House, and a great fear rose up to unsteady his hand as he made the turn out of the cross-road. Tregarvon’s fear was realized in some measure when, at Hartridge’s direction, the car made a second left-hand turn into the Westwood grounds and was brought to a stand before the door of the old mansion. “I have obeyed you blindly thus far,” he said, as he was lifting Hartridge out of the car. “But now you must tell me. Is it Judge Birrell?” “Wait,” said the schoolmaster, and Tregarvon helped the lame man up the steps and steadied him while he groped for the knocker. Before he could knock, the door opened silently under the hand of the judge’s daughter, and Tregarvon again gave Hartridge an arm to help him over the threshold. Though the hall was but dimly lighted he saw at once that there had been a pitiful change in Richardia. There was the shadow of a deep grief in her eyes when she greeted him, and the hand that she gave him was nerveless and cold. He had never seen her in black before, and that, and the chill of the great hall and the grave silence of his car companion, made him feel as if he had entered a house of mourning.
