"That was the statement," said the doctor, "but I'm credibly informed there is a supply secretly hoarded in this country. However that may be, I am convinced that was the means used in Miss Reid's case. This poison must be introduced under the skin, by means of a cut or scratch, whereupon, the effect is instantaneously fatal. Twenty seconds is said to be the extreme length of time for life to remain in a body after the introduction of the venom. There is a distinct scratch on Miss Reid's upper right arm, so inflamed and poisoned as to leave no doubt in the matter." "That's why the body was removed," said the Professor, "lest that scratch be discovered." "Yes," agreed Wise, "and the other victim, Mr. Bruce, was killed by having the poison introduced into his stomach." "That was a different poison," said the doctor. "That was strychnine hydrochlorate, which acts with equal speed. The evidential point is, that these two poisons were both plotted to be used in the case I mentioned in England, which, however, was foiled before it was actually attempted. The grave wrong, was the account in the newspapers, which was so circumstantial and definite as to give information to whoever cared to use it. Can any one doubt that the villain in this case, read the article I speak of, which was in several of our American papers, and made use of his ill-gotten directions to achieve his purpose?" "How did it get into Mr. Bruce's stomach?" demanded Braye. "It was secretly placed in his tea or in the cake he was eating," declared the doctor. "Don't ask me how,--or who did it. That is not my province. But whoever could plan these fearsome deeds, could find an ingenious method of carrying out his plans,--of that I'm sure." "I wish I'd been present," said Braye, again, as he sighed deeply. CHAPTER XVIII Another Confession Pennington Wise and Zizi sat in the hall talking. It was part of Wise's policy never to hold secret conclaves with his little assistant, for, he said that the people who employed him were entitled to all his suspicions or deductions as they took shape and grew in his mind. Professor Hardwick joined them as Wise was saying, "What first turned your attention to the Room with the Tassels, Ziz? Why did you move into that room to sleep?" "Because the lock was oiled," Zizi replied, her black eyes glistening. "The first time I got a chance I looked at all the locks in the house, and only two were freshly oiled, and they had been well looked after,--I can tell you." "What did that prove to you?" Hardwick asked.
