By order of the authorities, the grave in which Madame du Bourg had been interred was opened, and the empty, broken coffin was found. This discovery fully confirmed the suspicions of the President du Bourg, and prompted him in the course he now resolved to pursue. V. Meanwhile Madame Julie de Serres, the young and lovely wife whom Captain Maurice de Serres had married abroad five years previously, and now brought to Paris for the first time, returned that day to her husband's house in a state of the utmost alarm and agitation. Pale and trembling, she begged to be conducted to Maurice, and the pair remained closeted together for several hours. At last, in outward semblance perfectly calm, she rejoined the Countess, her husband's mother, and from that day resumed the ordinary current of life as though nothing had arisen to mar its serenity. About a fortnight had elapsed since the occurrences above related, and the incident in the cemetery appeared to have been forgotten, or if remembered by the chance witnesses of the scene, it was generally supposed that the mysterious lady who had been seen by M. du Bourg merely bore a fortuitous resemblance to the President's deceased wife. But during these few days, aided by all the power in the hands of the Lieutenant-General of Police, M. du Bourg instituted a searching and systematic investigation, firmly resolved as he was to know the truth. Without in the least suspecting that their every movement was watched, Captain de Serres and his wife were surrounded with spies, who rendered a daily report of their minutest actions. Maurice having come to the conclusion that it would be imprudent to leave Paris, there was no difficulty in keeping him under constant observation. Setting to work like an experienced lawyer, M. du Bourg rapidly collected evidence of the greatest importance. Through the Minister of War, he ascertained the exact date of Captain de Serres' return to France, after his captivity and supposed death in the Indies. At the passport office he found out the day of the young officer's departure shortly after his arrival in Paris. The postillions whom he had employed on his journey to Havre were discovered and interrogated. From them it was elicited that the traveller had been accompanied to the coast by a lady closely veiled, who never left the carriage until the pair reached their destination. The name of the vessel in which M. de Serres and a lady inscribed as his cousin had taken passage to South America was ferreted out, and the ship's journal was brought to Paris. [Illustration: "SHE BEGGED TO BE CONDUCTED TO MAURICE."] Armed with these formidable proofs, the President du Bourg demanded from the High Court of Paris the dissolution of the illegal marriage between Captain Maurice de Serres and the pretended Julie de Serres, who, as M. du. Bourg solemnly declared, was Gabrielle du Bourg, his lawful wife.
