“No. Long before the enactment of the tragedy, this woman and her myrmidons, Victor Bérard and Pierre Rouillier, alias Chavoix, had discovered who Glanville was, and also that he had a brother who would inherit the estate in the event of his decease. Yet the plot does not seem to have occurred to them until after his imprisonment. My husband arrived in England several days earlier than I expected—”
“And they murdered him?”
“Yes. From place to place they followed him until a fitting opportunity occurred, and, as you are aware, they carried out their evil design in an omnibus in a clever, audacious manner that baffled the police. The murder remained a mystery, and it was not until several months afterwards that I succeeded in obtaining conclusive evidence proving that either Valérie or her accomplice, Bérard, assassinated him. They were unaware that I had married him, for I had returned to Paris and gone upon the stage again. But I afterwards accepted a London engagement, and set myself to watch the development of their skilfully concocted plans.”
“But what was their object in taking his life?” Hugh inquired, bewildered by the extraordinary narrative.
“It was quite plain. Immediately after our marriage, before we left the chapel, I told Douglas that it was Valérie who had killed Nicholson, and not himself, as he believed. The reason I did so was in order that he should see how he had been tricked, and the announcement, I feel sure, transformed his love for her into deadly hate. Before he left ‘La Nouvelle’ I believe he managed to write to her explaining that he had discovered her treachery, and announcing his intention of seeking revenge. It was the knowledge that he had discovered her secret that first prompted them to murder him. Their design was a deep one, to ultimately obtain your money. They saw that it was impossible for Valérie to marry Douglas after what had occurred, while on the other hand it was obvious that if they killed him the estate would pass to you, and Valérie could afterwards marry you for the sole object of obtaining possession of the money. They believed, too, that if Douglas died, Valérie’s secret would be safe, therefore what greater incentive to commit the murder could there have been?”
“Could they not have obtained his money without taking his life?” asked Hugh.
“No. The preservation of the secret of Valérie’s guilt was to them of vital importance, for while Douglas lived he would always have her in his power. She little thought, however, that it was I who had witnessed her crime and told Douglas the truth. She felt confident that by killing him she would be free.”
“And that she did, alas!” Trethowen added bitterly. “Ah! you have little idea of the terrible extremities to which they resorted in order to ensure the success of their nefarious plot. Indeed, the conspiracy was a devilish one; they hesitated at nothing. They had no money when Valérie commenced to allure you by her crafty smiles, and you would never imagine how they obtained sufficient to make you believe she was wealthy.”
“How did they? Tell me.”
“Rouillier—whom you know as Chavoix—is an adroit swindler, and to his ingenuity the credit for it is due. Some months previously he had insured his life for a large amount, and having made a holograph will bequeathing the money to an imaginary person named Chavoix, he then succeeded in finding a poor, destitute Frenchman in Soho who slightly resembled himself. Aided by Bérard and Holt he drugged his victim, placed his own card-case and letters in his pocket, and flung him from a train on the District Railway. The insensible man was run over and killed. The body was discovered much mutilated, and the insurance company, believing that he had fallen from the train, paid the money over to Pierre, who was already living in a secluded village in Belgium, and who had taken the name of Chavoix.”
