"Now, Sybil Lamotte's strange flight gave proof that there was a skeleton in the Lamotte closet. I said:
"If this unseen Mr. Lamotte had planned this robbery, and if for some reason it seemed good that his daughter should elope, how well all was arranged.
"His son assisting him, they could drop down from Mapleton in their row boat; come up from the river, and, with their plans all laid, and knowing their ground, could make quick headway. Frank Lamotte's boot heel would leave just such a print, as one of the robbers left in the loose dirt beside the garden fence. Frank Lamotte would know just how to administer the chloroform. Then, Mr. Lamotte, in going to the city, ostensibly to procure the services of a detective, could easily take the spoils along; and his wife also, that she might be well out of his daughter's way. Such a man would naturally select a fellow like Jerry Belknap, who would keep up a farce of investigation, and keep away all who might, perhaps, stumble upon the truth. Frank's eagerness to be absent on this day of his sister's flight, and to assist in the search for the robbers, would be thus explained; and his anxiety concerning the contents of his sister's letter might be easily traced to a guilty conscience.
"But my theories were doomed to be laid aside for a time. Other duties claimed me and it was four weeks before I could turn so much as a thought toward W——.
"Before leaving the city, however, I had placed my wax cast of the chloroform bottle in the hands of one of my best men, and had also given him a clue upon which to work.
"My agent was wonderfully successful. He found the counterparts to the chloroform bottle, and then he began shadowing the owner of said vials. It proved to be a young woman who had formerly lived in W——, as a factory hand, but who had been transplanted to the city by Frank Lamotte.
"It is not necessary to enlarge upon the story of this girl as connected with Lamotte; but this must be borne in mind. During the time that my agent had this girl under surveillance, Frank Lamotte visited her, and, it is supposed that he removed the remaining bottles of the set, for one was afterward exhumed, in fragments, from Doctor Heath's ash heap, by the industrious Jerry Belknap, and the others have disappeared."
At the mention of this factory girl Mrs. Aliston turned her face toward Constance, its expression saying as plainly as any language could, "I told you so." But Mr. Bathurst took no notice of this, and hurried on with his story.
