But to Riguepeu...
You will not find it on anything but the biggest-scale maps. It is an inconsiderable town a few miles from Vic-Fezensac, a town not much bigger than itself and some twenty kilometres from Auch, which is the capital of the department of Gers. You may take it that Riguepeu lies in the heart of the Armagnac district.
Some little distance from Riguepeu itself, on the top of a rise, stood the Chateau Philibert, a one-floored house with red tiles and green shutters. Not much of a chateau, it was also called locally La Maison de Madame. It belonged in 1843 to Henri Lacoste, together with considerable land about it. It was reckoned that Lacoste, with the land and other belongings, was worth anything between 600,000 and 700,000 francs.
Henri had become rich late in life. The house and the domain had been left him by his brother Philibert, and another brother's death had also been of some benefit to him. Becoming rich, Henri Lacoste thought it his duty to marry, and in 1839, though already sixty-six years of age, picked on a girl young enough to have been his granddaughter.
Euphemie Verges was, in fact, his grand-niece. She lived with her parents at Mazeyrolles, a small village in the foothills of the Pyrenees. Compared with Lacoste, the Verges were said to be poor. Lacoste took it on himself to look after the girl's education, having her sent at his charges to a convent at Tarbes. In 1841, on the 2nd of May, the marriage took place.
If this marriage of youth with crabbed age resulted in any unhappiness the neighbours saw little of it. Though it was rumoured that for her old and rich husband Euphemie had given up a young man of her fancy in Tarbes, her conduct during the two years she lived with Lacoste seemed to be irreproachable. Lacoste was rather a nasty old fellow from all accounts. He was niggardly, coarse, and a womanizer. Euphemie's position in the house was little better than that of head domestic servant, but in this her lot was the common one for wives of her station in this part of France. She appeared to be contented enough with it.
About two years after the marriage, on the 16th of May, 1843, to be exact, after a trip with his wife to the fair at Riguepeu, old Lacoste was taken suddenly ill, ultimately becoming violently sick. Eight days later he died.
By a will which Henri had made two months after his marriage his wife was his sole beneficiary, and this will was no sooner proved than the widow betook herself to Tarbes, where she speedily began to make full use of her fortune. Milliners and dressmakers were called into service, and the widow blossomed forth as a lady of fashion. She next set up her own carriage. If these proceedings had not been enough to excite envy among her female neighbours the frequent visits paid to her in her genteel apartments by a young man did the trick. The young man came on the scene less than two months after the death of the old man. It was said that his visits to the widow were prolonged until midnight. Scandal resulted, and out of the scandal rumour regarding the death of Henri Lacoste. It began to be said that the old man had died of poison.
It was in December, six months after the death of Lacoste, that the rumours came to the ears of the magistrates. Nor was there lack of anonymous letters. It was the Widow Lacoste herself, however, who demanded an exhumation and autopsy on the body of her late husband—this as a preliminary to suing her traducers. Note, in passing, how her action matches that of Veuve Boursier.
On the orders of the Juge d'instruction an autopsy was begun on the 18th of December. The body of Lacoste was exhumed, the internal organs were extracted, and these, with portions of the muscular tissue, were submitted to analysis by a doctor of Auch, M. Bouton, and two chemists of the same city, MM. Lidange and Pons, who at the same time examined samples of the soil in which the body had been interred. The finding was that the body of Lacoste contained some arsenical preparation.
