She paused, placing her hand upon her panting breast.

“When she returned,” she continued at last, for the nervousness which had agitated her at first gave place to strength and confidence, “her first question was of Hartmann. I told her of his request, and how I had acceded to it, giving him a bottle of the wine she had so generously ordered for me. She grew livid in an instant, and stood speechless, glaring at me as though she would strike me dead. Then rushing up to the room she drew back the panel and called him by name. There was no response. In an instant she knew the truth. Without uttering a single word to me, but ordering the servants to close the house as we were going away for a week or two, she made instant preparations for departure, and after seeing everything securely bolted and barred, she left with a trunk on a cab for Fulwell Station, while I, with my small trunk, took refuge with my friends the Blains, with whom I have since remained.”

“But the motive of that secret assassination at Phillimore Place?” I asked, astounded at her story.

“Only within the past few days have I discovered it,” she answered. “The crime was planned with extraordinary care and forethought. If it were not for this confession which you have wrung from me, the police would never, I believe, have elucidated the mystery. The reason briefly was this. Coulter-Kerr was an Englishman living in Calcutta, who had been left a great indigo estate in the North-West by his uncle, and had returned to England with a view of selling it to a company. The estate, one of the finest in the whole of India, realised a very handsome income, but both he and his wife preferred life in England. Blain, being a speculator and promoter of companies, besides an importer of wines, having been introduced to him, conceived a plan of obtaining this magnificent estate, and with that object had approached Hartmann who in his turn had enlisted the services of Madame Damant, both of them being very desperate characters. Hartmann lived in London, and was supposed to be the most expert toxicologist in the whole world, while Madame was a woman whose previous adventures had earned for her great renown in certain shady circles on the Continent.

“Blain, it appeared, had already been out to India to visit the estate, and on his return had paid a couple of thousand pounds deposit, agreeing to purchase it privately of Kerr for two hundred thousand pounds—the valuation made upon it by a valuer whom he had taken up with him from Bombay—and then to turn it into a company. A date was arranged when the money should be paid over at the house in Phillimore Place in exchange for the deeds duly executed, Hartmann, in whose experiments Kerr was so interested, to be present to witness any document necessary. In accordance with Blain’s request the deeds were therefore prepared beforehand and executed, and all the papers relating to the transaction placed in order in the large deed-box in which they had been brought from India. In accordance with the cunningly-devised plan, Blain called upon the Kerrs on the afternoon arranged—the afternoon of the day of the tragedy—and found Kerr ready with all the legal papers and receipts duly executed. Blain, however, was profuse in his apologies, stating that, owing to some slight difficulty with his bank, he was unable to draw that day, but would do so on the day following, and would return at the same hour. The Kerrs, on their part, expressed regret that they could not ask him to remain to dinner, but explained that they had no servants.”

Again she paused. Her story held us all speechless.

“I have already explained how the Kerrs afterwards visited me and took tea, and the terrible tragedy which followed. Hartmann was, without doubt, concealed in that house at the time, watching for the unfortunate man’s end, and without delay secured the deed-box and all the receipts and papers, carrying them next door, searching the body of the man, and placing certain things in his pockets, namely, the forged banknotes and the penny wrapped in paper, which would puzzle the police, while Blain had caused that same evening to be posted from the Grand Hotel in Paris, a letter to the man now dead, addressed to Drummond’s Bank, expressing satisfaction at the termination of the negotiations, and acknowledging the safe receipt of the deeds and transfers from the messenger he had sent. This was, of course, to carry out the fiction that for several weeks he had been in Paris on business connected with the floating of the company, and to enable him to prove an alibi if ever required. Blain, when in India, took good care that it should be widely known that he intended to purchase the estates, so that his sudden possession would not be considered strange. There was a man, it afterwards transpired, who was actually staying at the Grand in Paris in the name of Blain, and he had posted the letter, while I further discovered that this ingenious swindler had actually borrowed the sum of two hundred thousand pounds for three days to pass through his bank, so that he might show that he had paid for the property.”

“Then Blain is in actual possession of the deeds, which only require the stamp of the courts in India for the property to become his?” Boyd observed.

“Yes,” responded my beloved. “But the fear that you have discovered the dead man’s identity has hitherto prevented him taking possession or raising money on the deeds. He has placed them somewhere in safety, I suppose, and is now most likely out of the country.”

“Absolutely astounding!” I gasped. Then, on reflection, I inquired the meaning of the cards which had so puzzled us.
