“You seem very confident of success,” observed The Phantom.
“Our success is already assured. In a few days I shall be wealthier than I ever before dreamed of being. Some people scoff at money, but it is an excellent thing for all that. All my life, while pursuing my scientific investigations, I have had my eye on what you Americans call the main chance. I never dreamed that I should realize my hopes through an accidental discovery. Ever hear of the datura plant?”
The Phantom shook his head.
“It grows in great profusion in my native soil, the Malay States, but it can be transplanted or produced almost anywhere. It is an odd plant, from four to six feet high, with wide-spreading branches and black flowers that are shaped like trumpets. Children have been known to die after eating the seeds, which are very poisonous. A few years ago, after an extensive tour in Europe, I returned to my native land and was called upon to treat a child who had eaten a great quantity of the seeds. It was then I made the discovery that shall make me a wealthy man in a few days. It was a mere accident, but isn’t our whole life a series of accidents?”
He smiled philosophically, for he had quite recovered from the effects of his recent humiliation.
“If you will permit me to explain a little further,” he went on, “I think you will understand how invincible we are and how foolish it is for you to oppose us. The poisonous property of the datura plant is known as daturin. It is a very curious drug. Its active principle is a mixture of a kind of atropine and hyoscyamine, but the true nature of the component alkaloids has never been fully determined. It is one of the mysteries of nature. Among the symptoms of datura poisoning are hoarseness, dryness of the mouth, dilation of the pupils, disturbed heart action, bad memory, and a curious vocal affection that produces involuntary laughter. No chemical antidote had been either known or suggested until I made my accidental discovery. It has suited my purpose to keep that discovery to myself.”
There was an elated smirk on his face, and The Phantom turned away in disgust.
“I came to America,” continued the doctor in oily tones, “and by mere chance made the acquaintance of our remarkable Mr. Shei. I shall not weary you by reciting all the details. I happened to mention my discovery to Mr. Shei, and his brilliant mind immediately conceived the idea of putting it to a highly profitable use. Like all great things, his plan was simplicity itself. His theory was based on the fact, so aptly stated by yourself last night, that the average run of mortals can be most effectively controlled through the factor of fear. He suggested that if a deadly malady were communicated to a number of wealthy men, they could easily be persuaded to pay almost any price for a sure antidote, especially if the antidote were the exclusive property of an individual or an organization.
“That was the beginning of the idea. It required quite a little elaboration. The chief factors in the plan were the poison and the antidote. The antidote was in readiness, but the poison had to be so adjusted that it would produce death within a specified time unless the antidote were administered meanwhile. If the plan was to succeed, we must be in a position to tell the subjects that they would die within a certain number of days unless they paid our price for the antidote. You probably know, since you appear to be an educated man, that the ancient Chinese knew how to adjust poisons so as to produce death within a certain time. All my life I have been making special studies along that line, and my discoveries proved very valuable in connection with Mr. Shei’s project. Yet, for a long time, I was unable to adjust the poison with sufficient accuracy. With Mr. Shei’s assistance I fitted up a laboratory here and began making additional researches. It was necessary to have human subjects for the experiments, and Mr. Shei furnished me several. Two or three, who were inoculated in the early stages of the work, failed to react properly to the antidote, and one or two of them were unfortunate enough to die.”
“You murdered them, in plain words,” suggested The Phantom curtly.
