It was now his turn to offer suggestions. A stage-driver is always a person of importance, especially in California. For the past six days Mat had found his public importance rather embarrassing. Every trip past the robbers' hiding-place had brought an avalanche of questions from curious passengers. Probably Mat Bailey had been forced to think of the tragedy more constantly than had any other person. His opinion ought to be valuable. He hesitated, and seemed loath to speak his mind. "Out with it, Mat," said Francis. "This hearing is among friends, not official. Tell us just what you think." "Well," replied Mat, "there is one circumstance you gentlemen ought to know. Up to this time nobody has mentioned it; and I hate to be the first to speak of it." Everybody's interest was aroused. After a pause Mat continued: "When the robber was going over the baggage he came to Mr. Cummins' valise, and asked, 'Whose is this?' One of the passengers spoke up and said, 'That belongs to Mr. Cummins.' Then the row began." "Who is the guilty man?" cried Francis. Mat looked embarrassed: "It wasn't a man. It was Miss Slocum." There was a moment of silence. Everybody was shocked, and trying to work out in his own mind some logical connection between the school-teacher and the crime. "That's where you've got us guessing, Mat," said one. "What can a crowd of bachelors do if you drag a woman into the case?" "And yet," said another, "what else ought we to expect? A woman's at the bottom of everything, you know." "Yes, we would none of us be here in this wicked world except for our mothers," remarked the doctor sarcastically. "How has Miss Slocum been acting since the tragedy, Mat? I must confess I can't think ill of that girl." "Well, Doctor," replied Mat, "she has acted just as you would expect an innocent girl to act. She's been all broken up--down sick a good part of the time. And I don't believe there's a man, woman, or child in Nevada City who mourns Will Cummins more than she does. That's why I hate to mention her name. And that's why I haven't said anything up to this time. But some of those cowards who looked on while Cummins was murdered have begun to talk; so you would have heard the story sooner or later anyhow. Still, I hate to mention the girl's name." "You have done right," said Francis. "The girl might have helped the robbers without intending to. Frightened out of her wits, perhaps. Somebody might question her kindly, and see what's back of this. And, gentlemen, as Bailey spends a good deal of his time at Nevada City, it seems to me he is the man to follow up this clue. Call on the girl, Mat, and see what you can find out."
