"No, Rudolph," said the Professor. "There was nothing to be seen or deduced from anything that happened at that time. I was nearest to Mr. Bruce, Miss Carnforth was nearest to Vernie. Neither of us saw anything suspicious or of unexplainable intent." "And yet Mr. Bruce was poisoned," said Wise, glancing from one face to another. "And I feel positive Miss Reid was also poisoned. She must have been. What else could have killed her, like that?" "True enough," and Braye nodded his head. "But do you think an examination of her body, after all this time, could prove that?" "Whether it could or not," said Wise, "we want to recover the body if possible. My theory is that it must have been thrown in the lake. If it was taken away through the revolving column, what else could have been done with it? To bury it would have been to risk discovery. And Zizi's experience----" "Are you sure, Mr. Wise, that Zizi's experience was truthfully related? May she not have been hysterically nervous, and imagined the whole thing? I've heard of such cases." "Who put you up to that idea, Miss Carnforth?" said Wise, very quietly, and Eve flushed and turned aside, remaining silent. Pennington Wise's theory proved the true one. The men employed to drag the lake at Black Aspens succeeded in finding the body of Vernie Reid. A bag of bricks had been tied to the ankles, in the same manner as described by Zizi, and the little form had been sunk in almost the same place that Zizi had been flung into the water. Reverent hands carried the body to the house, and later it was examined by a skilled physician from New York City. He reported that death had ensued upon the girl's arm being scratched with some sharp implement, which had been previously dipped in a powerful poison. As this was the same physician who had passed the final judgment on the cause of Mr. Bruce's death, his report was listened to with confidence and belief. "You must know," he said, to the awed group, "that about last March, a plot was formed against some high officials in England. These diabolical plans included the use of extremely poisonous drugs. By a most culpable oversight the names and descriptions of these poisons crept into the public press, and since then, several attempts at their use have been made, mostly, I am glad to say, without result. "But, it is clear to me, that the murderer of these two people, Mr. Bruce, and the child, Vernie Reid, used the poisons I have told you of." "I read about them," said Pennington Wise. "They included a rare drug only to be obtained from South America."
