Neither the outer gate nor the front door showed any marks of violence. The key was in the lock of the door, inside. Not a single bar had been wretched; the locks, shutters, and bolts were all untampered with. The walls showed no traces that could betray the passage of the criminals. The chimney-posts, of red clay, afforded no opportunity for ingress or escape, and the roofing was sound and unbroken, showing no damage by violence.

On entering the first-floor rooms, the magistrates, the gendarmes, and Bibi-Lupin found the widow Pigeau strangled in her bed and the woman strangled in hers, each by means of the bandana she wore as a nightcap. The three thousand francs were gone, with the silver-plate and the trinkets. The two bodies were decomposing, as were those of the little dog and of a large yard-dog.

The wooden palings of the garden were examined; none were broken. The garden paths showed no trace of footsteps. The magistrate thought it probable that the robber had walked on the grass to leave no foot-prints if he had come that way; but how could he have got into the house? The back door to the garden had an outer guard of three iron bars, uninjured; and there, too, the key was in the lock inside, as in the front door.

All these impossibilities having been duly noted by Monsieur Popinot, by Bibi-Lupin, who stayed there a day to examine every detail, by the public prosecutor himself, and by the sergeant of the gendarmerie at Nanterre, this murder became an agitating mystery, in which the Law and the Police were nonplussed.

This drama, published in the Gazette des Tribunaux, took place in the winter of 1828-29. God alone knows what excitement this puzzling crime occasioned in Paris! But Paris has a new drama to watch every morning, and forgets everything. The police, on the contrary, forgets nothing.

Three months after this fruitless inquiry, a girl of the town, whose extravagance had invited the attention of Bibi-Lupin’s agents, who watched her as being the ally of several thieves, tried to persuade a woman she knew to pledge twelve silver spoons and forks and a gold watch and chain. The friend refused. This came to Bibi-Lupin’s ears, and he remembered the plate and the watch and chain stolen at Nanterre. The commissioners of the Mont-de-Piete, and all the receivers of stolen goods, were warned, while Manon la Blonde was subjected to unremitting scrutiny.

It was very soon discovered that Manon la Blonde was madly in love with a young man who was never to be seen, and was supposed to be deaf to all the fair Manon’s proofs of devotion. Mystery on mystery. However, this youth, under the diligent attentions of police spies, was soon seen and identified as an escaped convict, the famous hero of the Corsican vendetta, the handsome Theodore Calvi, known as Madeleine.

A man was turned on to entrap Calvi, one of those double-dealing buyers of stolen goods who serve the thieves and the police both at once; he promised to purchase the silver and the watch and chain. At the moment when the dealer of the Cour Saint-Guillaume was counting out the cash to Theodore, dressed as a woman, at half-past six in the evening, the police came in and seized Theodore and the property.

The inquiry was at once begun. On such thin evidence it was impossible to pass a sentence of death. Calvi never swerved, he never contradicted himself. He said that a country woman had sold him these objects at Argenteuil; that after buying them, the excitement over the murder committed at Nanterre had shown him the danger of keeping this plate and watch and chain in his possession, since, in fact, they were proved by the inventory made after the death of the wine merchant, the widow Pigeau’s uncle, to be those that were stolen from her. Compelled at last by poverty to sell them, he said he wished to dispose of them by the intervention of a person to whom no suspicion could attach.

And nothing else could be extracted from the convict, who, by his taciturnity and firmness, contrived to insinuate that the wine-merchant at Nanterre had committed the crime, and that the woman of whom he, Theodore, had bought them was the wine-merchant’s wife. The unhappy man and his wife were both taken into custody; but, after a week’s imprisonment, it was amply proved that neither the husband nor the wife had been out of their house at the time. Also, Calvi failed to recognize in the wife the woman who, as he declared, had sold him the things.
