Some twenty years or so before the opening of the present story, Monsieur Arnold Beroldy, a native of Lyons, arrived in Paris accompanied by his pretty wife and their little daughter, a mere babe. Monsieur Beroldy was a junior partner in a firm of wine merchants, a stout middle-aged man, fond of the good things of life, devoted to his charming wife, and altogether unremarkable in every way. The firm in which Monsieur Beroldy was a partner was a small one, and although doing well, it did not yield a large income to the junior partner. The Beroldys had a small apartment and lived in a very modest fashion to begin with.

But unremarkable though Monsieur Beroldy might be, his wife was plentifully gilded with the brush of Romance. Young and good looking, and gifted withal with a singular charm of manner, Madame Beroldy at once created a stir in the quarter, especially when it began to be whispered that some interesting mystery surrounded her birth. It was rumoured that she was the illegitimate daughter of a Russian Grand Duke. Others asserted that it was an Austrian Archduke, and that the union was legal, though morganatic. But all stories agreed upon one point, that Jeanne Beroldy was the centre of an interesting mystery. Questioned by the curious, Madame Beroldy did not deny these rumours. On the other hand she let it be clearly understood that, though her "lips" were "sealed," all these stories had a foundation in fact. To intimate friends she unburdened herself further, spoke of political intrigues, of "papers," of obscure dangers that threatened her. There was also much talk of Crown jewels that were to be sold secretly, with herself acting as the go-between.

Amongst the friends and acquaintances of the Beroldys was a young lawyer, Georges Conneau. It was soon evident that the fascinating Jeanne had completely enslaved his heart. Madame Beroldy encouraged the young man in a discreet fashion, but being always careful to affirm her complete devotion to her middle-aged husband. Nevertheless, many spiteful persons did not hesitate to declare that young Conneau was her lover-and not the only one!

When the Beroldys had been in Paris about three months, another personage came upon the scene. This was Mr. Hiram P. Trapp, a native of the United States, and extremely wealthy. Introduced to the charming and mysterious Madame Beroldy, he fell a prompt victim to her fascinations. His admiration was obvious, though strictly respectful.

About this time, Madame Beroldy became more outspoken in her confidences. To several friends, she declared herself greatly worried on her husband's behalf. She explained that he had been drawn into several schemes of a political nature, and also referred to some important papers that had been entrusted to him for safekeeping and which concerned a "secret" of far reaching European importance. They had been entrusted to his custody to throw pursuers off the track, but Madame Beroldy was nervous, having recognized several important members of the Revolutionary Circle in Paris.

On the 28th day of November, the blow fell. The woman who came daily to clean and cook for the Beroldys was surprised to find the door of the apartment standing wide open. Hearing faint moans issuing from the bedroom, she went in. A terrible sight met her eyes. Madame Beroldy lay on the floor, bound hand and foot, uttering feeble moans, having managed to free her mouth from a gag. On the bed was Monsieur Beroldy, lying in a pool of blood, with a knife driven through his heart.

Madame Beroldy's story was clear enough. Suddenly awakened from sleep, she had discerned two masked men bending over her. Stifling her cries, they had bound and gagged her. They had then demanded of Monsieur Beroldy the famous "secret."

But the intrepid wine merchant refused point-blank to accede to their request. Angered by his refusal, one of the men incontinently stabbed him through the heart. With the dead man's keys, they had opened the safe in the corner, and had carried away with them a mass of papers. Both men were heavily bearded, and had worn masks, but Madame Beroldy declared positively that they were Russians.

The affair created an immense sensation. It was referred to variously as "the Nihilist Atrocity," "Revolutionaries in Paris," and the "Russian Mystery." Time went on, and the mysterious bearded men were never traced. And then, just as public interest was beginning to die down, a startling development occurred. Madame Beroldy was arrested and charged with the murder of her husband.

The trial, when it came on, aroused widespread interest. The youth and beauty of the accused, and her mysterious history, were sufficient to make of it a famous cause. People ranged themselves wildly for or against the prisoner. But her partisans received several severe checks to their enthusiasm. The romantic past of Madame Beroldy, her royal blood, and the mysterious intrigues in which she had her being were shown to be mere fantasies of the imagination.

It was proved beyond doubt that Jeanne Beroldy's parents were a highly respectable and prosaic couple, fruit merchants, who lived on the outskirts of Lyons. The Russian Grand Duke, the court intrigues, and the political schemes-all the stories current were traced back to-the lady herself! From her brain had emanated these ingenious myths, and she was proved to have raised a considerable sum of money from various credulous persons by her fiction of the "Crown jewels"-the jewels in question being found to be mere paste imitations. Remorselessly the whole story of her life was laid bare. The motive for the murder was found in Mr. Hiram P. Trapp. Mr. Trapp did his best, but relentlessly and agilely cross-questioned he was forced to admit that he loved the lady, and that, had she been free, he would have asked her to be his wife. The fact that the relations between them were admittedly platonic strengthened the case against the accused. Debarred from becoming his mistress by the simple honourable nature of the man, Jeanne Beroldy had conceived the monstrous project of ridding herself of her elderly undistinguished husband, and becoming the wife of the rich American.

Throughout, Madame Beroldy confronted her accusers with complete sang froid and self possession. Her story never varied. She continued to declare strenuously that she was of royal birth, and that she had been substituted for the daughter of the fruit seller at an early age. Absurd and completely unsubstantiated as these statements were, a great number of people believed implicitly in their truth.

But the prosecution was implacable. It denounced the masked "Russians" as a myth, and asserted that the crime had been committed by Madame Beroldy and her lover, Georges Conneau. A warrant was issued for the arrest of the latter, but he had wisely disappeared. Evidence showed that the bonds which secured Madame Beroldy were so loose that she could easily have freed herself.

And then, towards the close of the trial, a letter, posted in Paris, was sent to the Public Prosecutor. It was from Georges Conneau and, without revealing his whereabouts, it contained a full confession of the crime. He declared that he had indeed struck the fatal blow at Madame Beroldy's instigation. The crime had been planned between them. Believing that her husband ill-treated her, and maddened by his own passion for her, a passion which he believed her to return, he had planned the crime and struck the fatal blow that should free the woman he loved from a hateful bondage. Now, for the first time, he learnt of Mr. Hiram P. Trapp, and realized that the woman he loved had betrayed him! Not for his sake did she wish to be free-but in order to marry the wealthy American. She had used him as a cat's-paw, and now, in his jealous rage, he turned and denounced her, declaring that throughout he had acted at her instigation.

And then Madame Beroldy proved herself the remarkable woman she undoubtedly was. Without hesitation, she dropped her previous defence, and admitted that the "Russians" were a pure invention on her part.
