THE fact was, he wanted to think. Detective though he was and accustomed to the bravado with which every sort of criminal will turn to meet their fate when fully driven to bay, there had been something in the final manner of this desperate but evidently cultured gentleman, which had impressed him against his own will, and made him question whether the suspected man was not rather the victim of a series of extraordinary circumstances, than the selfish and brutal criminal which the evidence given seemed to suggest. Not that Mr. Byrd ever allowed his generous heart to blind him to the plain language of facts. His secret and not to be smothered doubts in another direction were proof enough of this; and had it not been for those very doubts, the probabilities are that he would have agreed with the cooler-headed portion of the crowd, which listened unmoved to that last indignant burst of desperate manhood. But with those doubts still holding possession of his mind, he could not feel so sure of Mr. Hildreth's guilt; and the struggle that was likely to ensue between his personal feelings on the one side and his sense of duty on the other did not promise to be so light as to make it possible for him to remain within eye and earshot of an unsympathetic crowd. "If only the superintendent had not left it to my judgment to interfere," thought he, pacing the streets with ever-increasing uneasiness, "the responsibility would have been shifted from my shoulders, and I would have left the young man to his fate in peace. But now I would be criminally at fault if I were to let him drift hopelessly to his doom, when by a lift of my finger I might possibly turn the attention of justice toward the real culprit." Yet the making up of his mind to interfere was a torture to Horace Byrd. If he was not conscious of any love for Imogene Dare, he was sufficiently under the dominion of her extraordinary fascinations to feel that any movement on his part toward the unravelling of the mystery that enveloped her, would be like subjecting his own self to the rack of public inquiry and suspicion. Nor, though he walked the streets for hours, each moment growing more and more settled in his conviction of Mr. Hildreth's innocence, could he bring himself to the point of embracing the duty presented to him, till he had subjected Miss Dare to a new test, and won for himself absolute certainty as to the fact of her possessing a clue to the crime, which had not been discovered in the coroner's inquiry. "The possibility of innocence on her part is even greater than on that of Mr. Hildreth," he considered, "and nothing, not even the peril of those dearest to me, could justify me in shifting the weight of suspicion from a guiltless man to an equally guiltless woman."
