Stone went to the window. Yes, that matter was easy enough. A balcony outside the long French window was connected with the lower verandah by a spiral staircase. Any one could run up the steps and be admitted to the boudoir in perfect secrecy. Stone wondered for a moment why Bates hadn’t entered that way, and quickly realized that for a marauder to appear at the window would have frightened Miss Carrington and caused an outcry. The entrance of the Count, however, whether expected or not, would be easily effected.
If the Count were really guilty, the circumstances were all explicable. Suppose Miss Carrington had made the appointment. Would she not, in her vanity, have donned the beautiful boudoir gown and the jewels to appear attractive in his eyes? And, supposing she had playfully caught his glove as he removed it, and had half-unconsciously continued to hold it. Then the conversation alleged to have been overheard by Miss Frayne would have been addressed to him, and the remarks would be, at least, intelligible.
The snake? Ah, yes, the snake. As to that there was no hint, no clue of any sort. But then, the thing was so inexplicable, that the explanation must be easy. A clue so strange, so bizarre, must lead somewhere. That could be left to the future. Now, he must decide on his first steps.
The decision took him to call on Doctor Stanton, and the physician welcomed him warmly.
“Glad to see you, Mr. Stone,” he said; “sit down, sir, sit down. I’ve been wanting a talk with you ever since I heard of your arrival. So you’ve ferreted out the burglar already! Great work, great work indeed! And now for the real murderer. You see, sir, I’m up to the minute in my information regarding this case.”
“Glad to know it,” returned Stone. “Now, Doctor Stanton, I hope you can help me. I don’t mind admitting the thing has its baffling aspects. The burglar was easily traced, and easily disposed of. The real work, as you say, is just beginning. Will you, sir, tell me all you know of the poison that killed Miss Carrington?”
“Surely, Mr. Stone. The autopsy showed a fatal dose of aconitine. Aconite, as you of course know, is the herb, wolfsbane, of the Hellebore tribe, all the species of which are poisonous. Aconitine is an intensely poisonous alkaloid obtained from aconite. Taken in a moderate quantity, it acts as a powerful sedative, but the dose absorbed by Miss Carrington was undoubtedly fatal within half or three-quarters of an hour.”
“And she died at what time?”
“About two o’clock.”
“Proving she took the poison at about quarter or half after one.”
