Referring to a note which he had made on the previous evening, Hal turned to pages 251-2, the part of the book which had fallen open three times in succession when he had examined it in Gerard's rooms, and noted that it was the Atchinson, Topeka & Santa Fe time-table, westbound. Evidently the missing merchant had invested in a copy of the Guide rather than run the risk of leaving telltale time-tables around his apartment, but he had overstepped himself by referring to only one portion of the book. "Not the first time that a crook has been just a little too clever," mused Preston, with a smile. "If it had been an old copy, there wouldn't have been any evidence--but a new book, opened several times at the same place, can be made to tell tales--his honor, the chief of police, to the contrary." It was clear, therefore, that Preston had three leads to work on: Anna Vaughan, a large, beautiful woman, well-dressed and with an affection for white mice; the clue that Gerard was somewhere in the Southwest and at least the first names of fourteen men and women connected with the gang. But right there he paused. Was there any gang? The dates of the various disappearances tended to prove that there wasn't, but the messages received by Gerard certainly appeared to point to the fact that others were connected with the conspiracy to defraud. Possibly one of the clerks who had been connected with the Gerard stores would be able to throw a little light upon the situation.... It wasn't until Hal interviewed the woman who had acted as cashier and manager for the second store that he found the lead he was after. In response to his inquiry as to whether she had ever heard the missing proprietor speak of any of the persons mentioned in the wires, the cashier at first stated definitely that she hadn't, but added, a moment later: "Come to think of it, he did. Not as people, but as trunks." "What's that?" exclaimed the operative. "Trunks?" "Yes. I remember sometime last spring, when we were figuring on how much summer goods we ought to carry, I mentioned the matter to Mr. Gerard, and almost automatically he replied, 'I'll wire for Edna and Grace.' Thinking he meant saleswomen, I reminded him that we had plenty, particularly for the slack season. He colored up a bit, caught his breath, and turned the subject by stating that he always referred to trunks of goods in terms of people's first names--girls for the feminine stuff and men's for the masculine. But Edna and Grace weren't on your list, were they?" "No," replied Preston. "But that doesn't matter. Besides, didn't the two trunks of goods arrive?" "Yes, they came in a couple of weeks later." "Before Mrs. Vaughan came to town?" "Oh yes, some time before she arrived."
