Thus it would be easy to explain afterward how great good fortune had kept Miss Mercedes in the city that night—and thus, when Isabel Benton appeared in her place in the world, any difference of character or appearance might easily be accounted for because of the horrors and the terrible losses through which she had passed.

Thus, the reader will understand, the culmination of Paul Rogers’ plotting would be achieved, and while the real Mercedes Danton was quietly put to death, the pseudo Mercedes—Isabel Benton—would appear in her place, in the enjoyment of her fortune and in the exercise of her prerogatives.

All this hellish plan was developed to Tom Morgan—or shall we confess at once what the reader already knows, and saw that he was really Tom Danton?—during the late afternoon and early evening of the eventful day upon which it was to happen.

And when he would have started away at once to warn his sister and his brother of the awful peril that hung over their heads, even if he was compelled to acknowledge his identity in order to do so, he was detained. Not because anybody suspected him of showing any interest in the affair other than that terrible interest which they all enjoyed, but because of the careful plans of their leader who had arranged for the conduct of every separate man with the care of a general in ordering a concerted attack upon the enemy.

This and that group of men were to start for the rendezvous at stipulated times, and they were to meet at specified points so that there could be no miscarriage of plans—and Tom Danton’s orders offered him no opportunity of starting out until nine o’clock.

Fortunately, however, he was to go alone, and he planned that at least he could get his sister and his parents out of the house before it was attacked.

But, oh, the long hours of waiting until the time for his start for the scene of the crime came around. But when he did start, there was no delay in his going.

And up at the Fells, one man sat in a rustic seat under a lattice where he was in deep shadow, waiting and watching for he knew not what.

That one man was Nick Carter, who knew nothing of the plot, or of the drug, which was at that moment being prepared for those who were in the house.

And Nick Carter, with only Burglar Tom Morgan for his aid, was to face all that crew of sixty-five human devils, upon murder and rapine bent.
