Alone, I sank into the chair utterly broken down, still holding in my nervous, trembling fingers the secret document that secured the peace and welfare of the two most powerful nations on earth. I had at last discovered the hideous truth. Ella, the woman whose grace and beauty had held me enmeshed, and whom I had loved with an intensity of passion that was all-consuming, was, after all, base and worthless. Although making a hollow pretence to love me, she had cast me aside for this mysterious man who signed himself with an initial, and who met her secretly almost daily. I had been a blind, devoted idiot, I knew, but until I had watched her in Kensington Gardens I had never suspected her of infamy. It seemed, however, that she had no sense of shame, and cared nought for my dishonour or despair. Her perfidy was now revealed in all its painful reality. Ella, whom I had always regarded as pure, honest and trusting, was a woman of tarnished repute. The fact that she had the secret convention in her possession was, in itself, sufficient evidence that the mystery surrounding her was deep, and of no ordinary character. Sonia had warned me that she was my enemy, and this fact was now indeed vividly apparent. How she had become possessed of the stolen treaty was inexplicable. Full well she knew all the terrible anxiety its loss had caused me, and the sensation that its revelation had created throughout Europe. Times without number I had mentioned to her how anxious my chief was to recover the original, so that our enterprising friends in St Petersburg could have no tangible proof that it had actually existed, yet she had given no sign that she knew anything of it, much less that it actually reposed in my own drawing-room. I did not fail, in those moments of my despair, to recollect that she had been on the most intimate terms with Dudley Ogle, the man suspected to have been in the service of the Tzar's Government, and as I sat in wonderment it became gradually impressed upon me that through those many months I had been basely tricked, and that Ella herself, charming and ingenuous as she seemed, was actually a secret agent of the enemies of England.
