Wiggins had foreseen this, and to guard against this necessity he had himself done all in his power to search after the missing man. He had put the case in the hands of detectives, who had carried on an investigation in all quarters, and in every possible way; but to no purpose, and with no result. When at length the authorities came, he informed them of his search and its failure, but assured them that he still believed that Captain Dudleigh was alive. His theory was that, being heavily in debt, he had taken this mode of eluding his creditors, and after causing it to be believed that he was dead, he had quietly disappeared, and was now enjoying himself somewhere on the Continent. No one else, however, shared this opinion, and those who came to the search had no doubt that the missing man had been murdered. So they instituted a regular search over the whole estate. They began with the Hall, and went through every part of it. Then they turned their attention to the grounds These were extensive, and it seemed probable that somewhere among the groves or swamps the remains might be found. They searched the chapel and the vaults. They dragged the pond in front of the house. In all this Wiggins lent his active assistance toward furthering the ends of justice, but at the same time retained the firmest conviction that it was a trick of Dudleigh's, and that he was now in foreign parts.

At length some of those who had been going the rounds of the wall returned to the house, carrying something, the sight of which produced a profound excitement. It was the hook and rope by which Edith, had sought to escape. They found it hanging upon the wall, and every one recognized at a glance the intention of this rope-ladder. But the thing that produced the strongest excitement was something else. They had found it lying among the grass at the foot of the ladder, having evidently been dropped by some fugitive as an impediment, or thrown away as useless. It was a dagger, which, from being so long exposed to the weather, was covered with rust, but was still sharp and deadly.

This dagger seemed at once to confirm the general impression. It showed that one of the fugitives of that night—the one who had escaped—had been armed with a deadly weapon. Every one knew who the one was who had escaped. Every one had already suspected her. Her wild flight, her terrible agitation, her long illness—all had been known. What else could cause such a state of things but the dread remembrance of some dark crime? And now this dagger lay before them, the silent proof of the guilt of her who had left it there.

Upon Wiggins the effect was crushing. His tongue was paralyzed. He kept aloof after that, with despair on his face, and surveyed the proceedings at a distance. Not so Mrs. Dunbar. All this time she had been feverish and agitated, sometimes following the officers, at other times retiring. Upon her the sight of that dagger acted like something that confirmed the worst of her fears, and she burst forth into wild wails and lamentations. She then urged the officers to renewed search, and finally told them all about her own discovery of the empty rooms on that eventful morning, and the singular behavior of the dog.

The mention of this created new excitement, and they at once asked where the dog now was.

Mrs. Dunbar did not know. The dog had disappeared most mysteriously, and they had seen nothing of him for a long time.

They then asked to be taken to the place where the dog had stationed himself. Mrs. Dunbar, still wild with excitement, led the way there. Arriving at the spot, they examined it narrowly, but found nothing. It was grass, which had not been touched for years. No body lay buried beneath that old turf, as was plainly evident. They then went to the out-houses, toward which Mrs. Dunbar told them the dog had kept his face, turned for some time when she had first seen him; but here they found nothing whatever.

It was now late, and they began to think of retiring, when suddenly one of the party, who had been walking in the rear of the stables, gave a call which drew them all in that direction. Upon reaching him they found him standing at the edge of a pit, which looked like an old well. Over this there was still the frame of what had been the well-house, and the well itself was very deep. Kneeling, they all peered into the black depths beneath them, but discovered nothing. One of them dropped a stone, and the sound far below showed that the bottom lay at least sixty or eighty feet from the surface.

“How long since this well has been used?” asked the sheriff.

“Many years,” said Mrs. Dunbar.
