"Yes. It was on receipt of the letter from Kobita that Souvaroff sent for you and requested you to put the obituary notice in the papers, in order that when the Siberian official came to claim his daughter's hand, he could convince him of her death. But this plan was not carried out quickly enough. Kobita arrived on the night of your visit, and was received by Prascovie's father, who stated that she had gone to call upon a friend in the vicinity, and offered to send his servant to direct him to the house in question. To this Prascovie's admirer had no objection, and, shaking Souvaroff warmly by the hand, wished him _au revoir_, and started off, accompanied by the servant, in search of the imaginary neighbour. The hand-shaking proved fatal, for he had not walked far before he fell dead. The whole thing had been carefully planned, and the trusty servant, who had been instructed how to act, extracted everything from the dead man's pockets that would lead to identification. Hence his burial in a nameless grave." "Do you assert that he was murdered?" "Yes. We were in possession of all these facts, but refrained from causing Souvaroff's arrest, because it was not a wise policy to expose to the London public that Russia had established a bureau of secret police in their midst. Prascovie and her father hid for some months, and we lost sight of them until she called upon you, and accompanied you in disguise to Siberia. Once or twice you very narrowly escaped being apprehended; indeed, on one occasion orders were telegraphed to Tomsk for the arrest of your companion and yourself, because the declaration on your passport regarding `Ivan Ivanovitch' was known to be false. By the intervention of a high official, however, the order was countermanded, and you were allowed to pass." "What has become of Prascovie's father?" I asked in astonishment. "Surely he was not Kobita's murderer, for the man died of heart disease." "You are mistaken. He died of Obeah poison. Souvaroff, who was once a consul in Hayti, knew of the secret poison which the natives extract from the gecko lizard, and which cannot be detected. So deadly is it, that one drop is sufficient to produce a fatal result, and the manner in which he administered it was somewhat novel. He prepared to receive his enemy by allowing the nail of the forefinger of his right hand to grow long, afterwards thinning it to a point as fine as a needle. Upon this point he placed the poison, and kept a glove on until Kobita's arrival. Then, in wishing him adieu, he pricked the skin of his victim while shaking hands with him, producing an effect similar to syncope." "Where is Souvaroff now?" "Dead. He returned to Petersburg as soon as his daughter had left with you, but was arrested and placed in solitary confinement in the Fortress. While there, he wrote a confession of the murder, and afterwards committed suicide." "And will they arrest Prascovie?"
