Mr. Heathcote recompensed the police-officer handsomely for the very little he had done; and so they parted, M. Drubarde vastly pleased with his client, but still better pleased with himself. He was a man whose benign consciousness of his own value in the social scale mellowed with advancing years. Having been thus abandoned by both his gifted coadjutors, Edward Heathcote worked on by his own lights. There was one person, he told himself, who might be able to assist him--one person whose chief desire in life must be to see the murderer of Marie Prévol and her lover brought to his doom. Among the few scraps of information which Trottier had given to his friend there was the fact that the dowager Baronne de Maucroix, the widowed mother of the murdered man, was still living. She resided at her château in Normandy, where she led a life of strictest seclusion, devoting herself to acts of charity and to the severest religious exercises. It was in the hope of obtaining an interview with this lady that Heathcote left Paris upon the very morning on which Miss Meyerstein telegraphed the news of Hilda's flight. He had no letter of introduction, no credentials to offer to Mdme. de Maucroix, except the one fact of his keen interest in the after-fate of her son's murderer. There was some audacity in the idea of so presenting himself before a venerable recluse of ancient family, a woman who, according to Sigismond Trottier, had been distinguished in her youth for pride and exclusiveness; a woman who had ranked herself with the Condés and the Mortemarts, who had ignored the house of Orleans, and loathed the Imperial rule. The château of the Maucroix family was about five miles on the eastward side of Rouen. It was situate on low ground, a little way from the banks of the Seine--an imposing pile of Gothic architecture, guarded by a moat, and approached by an avenue of funereal yews. The surrounding landscape was flat and uninteresting. The broad bright river, winding in bold curves across the level meads, with here and there a willowy islet, gave a certain charm to scenery which would otherwise have been without a redeeming feature. Far off in the distance the chimney-shafts and spires of Rouen rose dark against the gray October sky. Edward Heathcote felt the depressing influence of those level fields, the gloom of that dark avenue and sunless day. It seemed to him as if he were going into a grave, a place whence life and hope had fled for ever.
