### CHAPTER THE TWENTY-NINTH
#### ANOTHER PLOT

Among my letters on the following morning was a small packet which I opened. Within was a tablet of dark-brown toilet-soap bearing the name of a well-known firm of manufacturers. With it was a typewritten letter upon dark-blue commercial paper with a printed heading. I was addressed as “H. Granfield, Esq.,” and the letter proved to be a polite intimation that as the firm in question was putting on to the market a new brand of toilet-soap, they begged me to accept with their compliments the enclosed sample. I was also informed that, if I liked it, I could purchase it of their agents, a certain firm of chemists in King Street, Hammersmith.
“Looks rather decent soap!” remarked Harry as I passed it to him, and then I re-wrapped it in its paper and placed it aside.
At eleven o’clock I sat with Rivero, Gabrielle and Harry Hambledon in the dull reception-room at Scotland Yard, that same room wherein I had given information concerning the whereabouts of Mateo Sanz.
The Superintendent who received us was a well-dressed courtly man, rather stout and elderly, who became intensely interested when I related the whole story, much as I have set it down in the foregoing pages.
The consultation was a momentous one. Rivero sat amazed when I described my chance meeting with Gaston Suzor, and the clever manner in which I had been inveigled into De Gex’s house in Stretton Street. Indeed, on comparing Gabrielle’s story with my own, I now saw that at the time I entered the house both she and the girl Engledue were in their normal health. The coffee had not then been served though Moroni had gone out of the room, no doubt to put the drug into the cup which was to be offered to Gabrielle Tennison, and which apparently was placed by mistake before the mystery-man himself. Or else the changing of the cups was to allay any suspicion that might arise in the mind of the other victim, which was perhaps most likely.
According to Gabrielle, it seemed that at the moment of her seizure Horton re-entered the room and said some words in a low tone to his master, whereupon the latter rose, left the table, and evidently went to greet me, leaving Gabrielle in Miss Engledue’s care.
Horton, even though he had been engaged in serving the dinner at the rear of the house, was apparently also on the look-out for me, and now I recollected that on my journey down from York, I had mentioned to Suzor my habit of going to visit my uncle in Orchard Street on certain evenings. He had asked me to dine with him on the seventh, but I had excused myself as my uncle would expect me that evening. He evidently held previous knowledge that the route I habitually took was through Stretton Street, hence the plot to get me within that house. Besides, it was quite likely that Suzor himself was watching for me and had sent Horton out to call me. In any case, the plot had been well-timed and elaborately thought out.
The fact was plain that Gabrielle Engledue, who had sent her luggage to the station cloak-room and was about to return to Madrid, was killed, probably by the scratch of a pin upon which orosin had been placed.
“All this is most astounding,” declared Superintendent Fletcher. “Of course, De Gex contrived that no inquiry would be made concerning the dead girl. He might have shown you the body of Miss Engledue, but he had some motive in keeping it from you, and obtaining a death certificate for the girl who was still living.”
“The motive was that he was not quite certain whether the orosin could be detected. Since then he has grown bolder, as witness the murder of the Baron van Veltrup,” I replied.
“But why should he not have shown you the dead girl?” queried the Superintendent.
“Because he no doubt wished to mystify me in case of my recovery from the effects of the drug,” was my reply. “He was not quite certain of the effect that the dose might have upon me, so in order to entirely mislead me, so that if I recovered my statements would be discredited, he showed me a girl who was still living, though to all intents dead. Indeed, I have come to the conclusion that, aided by Moroni, he purposely contrived that I should meet and recognize in Miss Tennison the girl I had been told was the dead girl Gabrielle Engledue. And I confess that I have been sorely puzzled all along that the girl whom I had seen dead was actually alive, even though her mental state was such as to show that she had met with foul play.”
“Yes,” remarked Rivero. “The plot was very cunningly conceived, especially the manner in which you were entrapped and induced to give the certificate.”
“Here is the money which De Gex gave me for my share in the crime,” I said openly, laying the bank notes upon the Superintendent’s table. “I suppose some action will be taken against me, but I am prepared to take the consequences, now that I have unmasked one of the greatest and most dangerous criminals of modern times.”
“You certainly have done that, Mr. Garfield,” remarked Superintendent Fletcher. “And I venture to think that the part which you have played in solving this problem will be taken into account when your own actions are considered.”
“It seems to me,” remarked Rivero, “that the reason the poison-maker, Moroni, evinced such a keen interest in Miss Tennison, and his reason for taking her to a number of specialists was solely in order to gain their opinions and so further study the effects of the deadly drug which he prepared.”
“I have learnt,” I said, “that Moroni was the laboratory assistant of the late Professor Orosi, the discoverer of the drug.”
“Ah! Then of course he knows the secret of its preparation, how to administer it, and in what doses,” remarked Fletcher.
“Even to-day,” I said, “I have had yet another attempt upon my life made by these scoundrels,” and from my pocket I drew the little packet containing the sample cake of toilet-soap, which I displayed to them all. Then, handling it in the thick brown paper wrapping, I took my pocket-knife and scraped the soap, quickly revealing a number of sharp steel points imbedded in it.
“You see there are sharp clippings in it! Each has no doubt been treated with orosin!” I said. “Had I washed my hands with it as a trial, they would have become scratched and infected with the deadly poison before I was aware of it.”
“Sanz has no doubt sent you that!” remarked Rivero instantly.
“Well, Hugh, it is certainly a providential escape that you discovered in time this latest plot against you!” exclaimed Gabrielle. “Really the craft and cunning of De Gex is without limit.”
“But I think, Miss Tennison, that you need have nothing further to fear from him,” said the Superintendent with satisfaction. “He has no doubt, very powerful friends, and if the evidence were not so damning and direct as that collected after so much patience and perseverance by Mr. Garfield, he might perhaps wriggle out of it. But once we have him he can hope for no escape,” he added. “And we shall arrest him before an hour is out. Fortunately he is still quite unsuspicious, though his chief fear is of Mr. Garfield, and of the ugly revelations which either Moroni or Sanz could make. Nevertheless we shall see!”
