"I am going to tell you nothing of the kind," answered Dr. Westbrook.
"I can find no symptoms of disease. You have a very fair lease of life,
Mr. Dale, and may enjoy a green old age, if other people would allow
you to enjoy it."
"How do you mean?"
"I mean that if I can trust my own judgment in a matter which is sometimes almost beyond the reach of science, the symptoms from which you suffer are those of slow poisoning."
"Slow poisoning!" replied Douglas, in almost inaudible accents. "It is impossible!" he exclaimed, after a pause, during which the physician waited quietly until his patient should have in some manner recovered his calmness of mind. "It is quite impossible. I have every confidence in your skill, your science; but in this instance, Dr. Westbrook, I feel assured that you are mistaken."
"I would gladly think so, Mr. Dale," replied the doctor, gravely; "but I cannot. I have given my best thought to your case. I can only form one conclusion—namely, that you are labouring under the effects of poison."
"Do you know what the poison is?"
"I do not; but I do know that it must have been administered with a caution that is almost diabolical in its ingenuity—so slowly, by such imperceptible degrees, that you have scarcely been aware of the change which it has worked in your system. It was a most providential circumstance that you came to me when you did, as I have been able to discover the treachery to which you are subject while there is yet ample time for you to act against it. Forewarned is forearmed, you know, Mr. Dale. The hidden hand of the secret poisoner is about its fatal work; it is for you and me to discover to whom the hand belongs. Is there any one about you whom you can suspect of such hideous guilt?"
"No one—no one. I repeat that such a thing is impossible."
"Who is the person most interested in your death?" asked Dr. Westbrook, calmly.
"My first cousin, Sir Reginald Eversleigh, who would succeed to a very handsome income in that event. But I have not met him, or, at any rate, broke bread with him, for the last two months. Nor can I for a moment believe him capable of such infamy."
