The business which had taken Mr. Byrd to Monteith kept him in that small town all day. But though he thus missed the opportunity of attending the opening of the inquest at Sibley, he did not experience the vivid disappointment which might have been expected, his interest in that matter having in some unaccountable way subsided from the moment he saw Imogene Dare take the cars for Buffalo. It was five o'clock when he again returned to Sibley, the hour at which the western train was also due. In fact, it came steaming in while he stood there, and, as was natural, perhaps, he paused a moment to watch the passengers alight. There were not many, and he was about to turn toward home, when he saw a lady step upon the platform whose appearance was so familiar that he stopped, disbelieving the evidence of his own senses. Miss Dare returned? Miss Dare, who but a few hours before had left this very depot for the purpose, as she said, of making a visit of more or less length in the distant city of Buffalo? It could not be. And yet there was no mistaking her, disguised though she was by the heavy veil that covered her features. She had come back, and the interest which Mr. Byrd had lost in Sibley and its possible mystery, revived with a suddenness that called up a self-conscious blush to his hardy cheek. But why had she so changed her plans? What could have occurred during the few hours that had elapsed since her departure, to turn her about on her path and drive her homeward before her journey was half completed? He could not imagine. True, it was not his present business to do so; and yet, however much he endeavored to think of other things, he found this question occupying his whole mind long after his return to the village hotel. She was such a mystery, this woman, it might easily be that she had never intended to go to Buffalo; that she had only spoken of that place as the point of her destination under the stress of her companion's importunities, and that the real place for which she was bound had been some spot very much nearer home. The fact, that her baggage had consisted only of a small bag that she carried on her arm, would lend probability to this idea, yet, such was the generous character of the young detective, he hesitated to give credit to this suspicion, and indeed took every pains to disabuse himself of it by inquiring of the ticket-agent, whether it was true, as he had heard, that Miss Dare had left town on that day for a visit to her friends in Buffalo. He received for his reply that she had bought a ticket for that place, though she evidently had not used it, a fact which seemed at least to prove she was honest in the expression of her intentions that morning, whatever alteration may have taken place in her plans during the course of her journey. Mr. Byrd did not enjoy his supper that night, and was heartily glad when, in a few moments after its completion, Mr. Ferris came in for a chat and a cigar.
