"Exactly! You see, the victim of a snake bite often is unable to move or speak. Doctor Blake observed that in the case of the stricken star. Her nerves were affected, resulting in paralysis of the muscles of the heart and lungs and giving us some symptoms of suffocation. Then the blood, as a result of the attack of the venom, is always left dark and liquid. That, too, I observed in the sample sent me from Tarrytown.
"The snake," Kennedy continued, "administers the poison by fangs more delicate than any hypodermic. Nature's apparatus is more precise than the finest appliances devised for the use of a surgeon by our instrument makers. The fangs are like needles with obliquely cut points and slit-like outlets. The poison glands correspond to the bulb of a syringe. They are, in reality, highly modified salivary glands. From them, when the serpent strikes, is ejected a pale straw-colored half-oleaginous fluid. You might swallow it with impunity. But once in the blood, through a cut or wound, it is deadly."
"There could be no snake in this case," I remarked. "The fangs of a serpent make two punctures, don't they; while here there was just the one scratch—"
"Of course there were no fangs when the deed was actually done," he rejoined, impatiently. "We've traced everything to the needle in the portieres and it is my belief that it was part of an all-glass hypodermic with a platinum-iridium point. It could hardly have been anything like the coarser syringe used by Werner, nor do I think it possible that the point of an ordinary needle would hold sufficient venom, since it would dry and form a coating like the incrustation on the inside of the ampulla McGroarty found."
"That was the venom?" I asked.
"Yes, I found it in the ampulla and in the stain on the portiere where the needle had pierced through."
"The towel, though—"
"Is something else. First thing in the morning we'll follow that up, as
I promised you. Meanwhile let's concentrate on motives."
A long line of private cars and taxicabs outside Jacques' testified to the popularity of the restaurant. At the door stood a huge, bulking negro resplendent in the glaring finery of his uniform. It seemed to me that people literally were thronging into the place, for it was cleverly advertised as a center of night life.
Inside, the famous darky jazz band was in full swing. There was lilt and rhythm to the melody produced by the grinning blacks, and not a free arm or foot or shoulder or head of any of them but did not sway in time to their syncopated music.
