She picked out four of the men, and ordered them to step forward; and, one by one, Nick directed each of them how to proceed after he had passed the entrance of the cavern with the men who were to follow him; and he made the directions so explicit that there was not one who had any doubt about being able to follow them.

It was as Nick had suspected it would be; that Madge did not yet trust him far enough to give him the sole leadership of one of the parties, but she directed that Handsome should go with him—and at the last moment, when they were ready to start, and after the other three parties had entered the cavern, she decided to accompany Nick's party herself.

"I may as well go along," she said. "I would like to learn something about the interior of that cavern myself, and I don't know a better way to learn it than to go with you."

And so it was that presently the detective found himself in the cavern, leading twenty-two persons, for the extra two were Madge and Handsome.

And the course that Nick had selected for himself was the one that would take him past the hiding place where he had left Patsy; for it was no part of his plan that he should give the others even a chance of an accident of finding that hiding place.

It had been shortly after eleven o'clock when Nick returned to the cabin after assisting Patsy in his escape; it was now after midnight.

There were torches and lanterns in abundance scattered among the four parties that were searching; and, in the directions that Nick had given each party, he had taken good care that they should become thoroughly lost if possible. He had an object in this, as will be seen.

The way through the cave along the route which the detective had selected to follow was smooth and even, as we already know; but Nick made it as long and as rough as possible by taking the party off into some of the side galleries as they proceeded.

He was looking for a place where he might lose some of them, and at least where he might, before the expedition was finished, succeed in separating them.

What he chiefly desired was to finally get either Madge or Handsome alone with him.
