Although there was no case, the prosecution was obstinately persisted in, not merely because the law officers were full of prejudice, but because, if they failed to secure conviction, they would be liable to a counter action for their high-handed abuse of legal powers. As has been said, no pains were taken at the first discovery of the death to examine the spot or investigate the circumstances. It was all the better for the prosecution that nothing of the kind was done. Had the police approached the matter with an open mind, judging calmly from the facts apparent, they would have been met at once by an ample, nay, overwhelming--explanation. There can be no doubt that Marc Antoine Calas committed suicide. The proofs were plain. This eldest son was a trouble to his parents, ever dissatisfied with his lot, disliking his father's business, eager to take up some other line, notably that of an advocate. Here, however, he encountered the prejudice of the times, which forbade this profession to a Protestant; and it was his known dissatisfaction with this law that led to the conjecture--and there was little else--that he wished to abjure his faith. At last Marc Antoine offered to join his father, but was told that until he learnt the business and showed more aptitude he could not hope for a partnership. From this moment he fell away, took to evil courses, frequented the worst company, was seen at the billiard tables and tennis courts of Toulouse, and became much addicted to gambling. When not given to debauchery he was known as a silent, gloomy, discontented youth, who quarrelled with his lot and complained always of his bad luck. On the very morning of his death he had lost heavily--a sum of money entrusted him by his father to exchange from silver into gold. All this pointed to the probability of suicide. The Calas themselves, however, would not hear of any such solution. Suicide was deemed disgraceful and dishonourable. Sooner than suggest suicide, the elder Calas was prepared to accept the worst. One of the judges was strongly of opinion that it was clearly a case of [Illustration: JEAN CALAS TAKING LEAVE OF HIS FAMILY. (_From the Painting by D. Chodswiecke, 1768._)] _felo de se_, but he was overruled by the rest, who were equally convinced of the guilt of the Calas. Not a single witness of the 150 examined could speak positively; not one had seen the crime committed; they contradicted each other, and their statements were improbable and opposed to common sense. Moreover, the murder was morally and physically impossible. Was it likely that a family party collected round the supper-table would take one of their number downstairs and hang him? Could such wrong be done to a young and vigorous man without some sort of struggle that would leave its traces on himself and in the scene around?
