Sonia, smiling in contempt, said,—
“The denunciation will be your own condemnation.”
“Why? What have I to lose?” he asked indignantly. “Your life. The police have not yet forgotten the tragedy at ‘The Nook.’”
He glared at her open-mouthed.
“Perhaps it may be well at this moment to recall some facts that you may have found convenient to forget,” she went on ruthlessly, while I, standing beside Ella, drank in eagerly every word. “You will remember where you reduced the stolen document to cipher, imitating Dudley’s handwriting on the telegraph forms. It was at my house. The envelope containing the agreement had been opened in the ‘cabinet noir’ at the Embassy, the intention being to replace it at the Foreign Office. But it was I who broke the seal. In your hurry you left the document behind, and even when you returned two hours later, your mind was so full of other things that you did not remember it; so I gummed down the cut edges, and sent it afterwards to Elizaveta. When you came the second time you had with you a pair of men’s gloves. Whose they were I knew not, but you got me to sew inside the index-finger of the left hand a tiny, jagged splinter of glass, and upon that glass, when you thought I did not observe you, you smeared some of that fluid that Ruyandez, the Haytian merchant, had given me long ago. That poison I kept locked away in a small cabinet, but many months before I had shown it to you and explained that it was some of that used by the Obeah men, and so rapid was it in effect that one single drop would cause paralysis of the heart within five minutes without leaving any trace of poison. You obtained a key to that cabinet, for when I had gone from the room on that afternoon I watched you unlock it, take out the reed containing the decoction, and prepare the glove.”
“Liar!” gasped Beck. “I didn’t touch it.”
“The glove,” she continued, “belonged to Dudley Ogle. That day Elizaveta had told him that you, a member of the English Parliament, was the chief of Russian spies, and you feared lest he should expose you, as no doubt he would have done if you had not, with cowardly cunning, taken his life.”
“Murderer!” cried Ella, amazed. “You—you killed him! Ah! I suspected it. Tell us, Sonia, how it was accomplished.”
“The gloves this man brought to my house were a pair he had taken up by mistake when at Shepperton on the previous evening. For cool and desperate plotting, the manner in which he killed the man he feared was astounding, for, having introduced into the finger of the glove the tiny piece of glass, he, during that evening at ‘The Nook,’ took out his victim’s gloves from his overcoat in the hall and replaced them by those prepared. When Dudley left to walk home he bade farewell to you, and at once proceeding to put on his gloves, received a scratch on the finger so slight as to be almost unnoticeable, yet within five minutes the effects of the poison had reached his heart, and he was beyond human aid.”
“Amazing!” I cried, regarding my whilom friend with intense loathing as he stood before us, his face a ghastly hue.
