A Son of Perdition by Fergus Hume

As Montrose had stated to Alice, his flight was looked upon as a tacit admission of guilt. Up to that moment Enistor had not been quite certain that Douglas was the culprit, as the young man had never given him the impression that he was one likely to proceed to such extremities. But this sudden disappearance could only mean that he had done so, therefore Enistor very naturally concluded that Montrose had been infuriated by Don Pablo's bitter tongue into revenging himself hastily. Probably he now regretted that haste, but whether he did so or not mattered little to the Squire. All that the master of Tremore knew was that his enemy was now at his mercy, and he intended to take full advantage of the opportunity. His first step was to inform the Perchton Inspector of that fatal visit to the cottage.

Then, very speedily, the hue and cry was out, and for miles round the police explored the country. There was no doubt in any one's mind as to the actual truth. The threats of Montrose, his presence at the cottage at the time when the crime had taken place, and now the unexpected disappearance -- these things showed that Douglas and none other was the guilty person. The next day every one was searching far and wide for the criminal, and Enistor was so vindictive that he offered a reward he could ill afford for the capture of the unfortunate young man. This he did to gratify the hatred which had existed for many incarnations, and also because he believed that when Montrose found it was impossible to escape the gallows, he would make over his wrongfully inherited money to Alice. And once Alice was in possession of the income, her father felt convinced that he would be able to handle the same. It was a very plausible plan, and Enistor worked hard to carry it out.
