to his mistress and friends; but even had the fact of the destruction of the will come to the ears of the Martignons, it is unlikely that they would have taken any steps involving the disgrace of Auguste. Castaing had enriched himself considerably by the opportune death of his friend Hippolyte. It might be made a matter of unfriendly comment that, on the first day of May preceding that sad event, Castaing had purchased ten grains of acetate of morphia from a chemist in Paris, and on September 18, less than a month before Hippolyte's death, he had purchased another ten grains of acetate of morphia from the same chemist. The subject of poisons had always been a favourite branch of Castaing's medical studies, especially vegetable poisons; morphia is a vegetable poison. Castaing's position relative to Auguste Ballet was now a strong one. They were accomplices in the unlawful destruction of Hippolyte's will. Auguste believed it to be in his friend's power to ruin him at any time by revealing his dealings with Lebret. But, more than that, to Auguste, who believed that his 100,000 francs had gone into Lebret's pocket, Castaing could represent himself as so far unrewarded for his share in the business; Lebret had taken all the money, while he had received no recompense of any kind for the trouble he had taken and the risk he was encountering on his friend's behalf. Whatever the motive, from fear or gratitude, Auguste Ballet was persuaded to make a will leaving Dr. Edme Samuel Castaing the whole of his fortune, subject to a few trifling legacies. But Auguste's feelings towards his sole legatee were no longer cordial. To one or two of his friends he expressed his growing distaste for Castaing's society.
