“My sister, too, has suffered terrible anguish,” Dora said. “She knew from the first that her husband was an assassin, yet to remove suspicion from him and avoid the terrible scandal, she was compelled to act a part that was to her revolting. That she had no thought for Gilbert and that she was faithful to her husband I am confident, yet in order to obtain confirmation of her suspicions of Fyneshade’s schemes she was compelled to court the friendship of Markwick, the man she most hated, while her husband, to avert suspicion that he had murdered Sternroyd, affected to be jealous of his confederate.”

“But my marriage,” I said, “it is astounding.”

“The plans of this base pair were indeed deeply laid and ingeniously formed,” she went on. “The crafty manner in which you were entrapped and wedded is but one illustration of their marvellous ingenuity and utter unscrupulousness. In securing the handsome revenue from my mother’s estates they provided for every eventuality, but by a conspiracy of circumstances Gilbert Sternroyd obtained knowledge of their secret, of how they had compelled me to pose as Markwick’s wife, and how they had married you to my dead sister. He sympathised with Mabel as wife of this titled adventurer, and, in order to rid her of him, intended to give him up to the police. My stepfather saw that only by death could he be silenced, and he therefore foully murdered him. Yes, Stuart, your marriage was an amazing one, secured by a scoundrel whose influence was far-reaching; but even that event was not one whit more astounding than those that followed.”

“True,” I said, amazed and bewildered at her disclosures.

“Towards me, also, Fyneshade has acted desperately, with double cunning.” Dora exclaimed fiercely, turning to me. “You remember on that night when, for the first time after your strange marriage, you visited the ghostly deserted house in Gloucester Square, I was there also. I knew that Fyneshade, supposed to be in Paris, was in hiding there, so I entered determined to face him and obtain liberty for Sybil, for Jack, nay for all, by compelling him to fly from the country and renounce all claim to return. I was prepared to offer him secrecy in exchange for this. But he detected us. He felled you from behind and dragged you down to the cellar, while he also stunned me, causing concussion of the brain; then locked me in that inner room. Probably I should have gone hopelessly insane and eventually starved had you not discovered me.”

“His villainy is revolting,” I exclaimed angrily. “His own action led to my discovery of the body, but I confess these disclosures put a complexion on the affair such as I had never dreamed;” and turning to Sybil, who had slowly risen and passed to the window, I asked, “Tell me the reason you are now constrained to make this confession.”

The air from the garden fanned her pale cheeks soothingly. She was leaning forward gazing fixedly across the lawn, but turned slowly at my words, and I saw her face was as beautiful as when we had first met.

“Because I no longer fear,” she answered calmly, and one would have doubted that this was the same woman who had been so wildly agitated only a few moments previously, she spoke so quietly. “Yesterday the French Government adopted an amnesty to political offenders, therefore the warrant cannot now be reissued against me. As to the ingenious fraud to which I have been a party, I can prove that I was merely a tool in the hands of these two malefactors who held me in their toils. From this moment I renounce the name of Markwick, to which I have no right, and again resume my maiden name, Sybil. I may be prosecuted—well, I am ready to take my trial—I—I am ready to face all, if only I can think that you believe me innocent, Stuart—if only I may dare to hope we may even be man and wife.”

Next second she was in my embrace, sobbing again with her head upon my shoulder.

“Rest assured,” I said tenderly, “that the innocent shall not suffer, and upon the guilty shall fall punishment swift and certain. If it becomes necessary for you to face a criminal trial, remember that I love you just as fondly as I have ever done.”
