Then his voice dropped once more into mutterings that I could not translate, but I had heard enough to cause me to guess a great deal more, and I thanked the kind Providence that had led me to this chamber at a time so filled with importance to Dejah Thoris and myself as this.

But how to pass the old man now! The cord, almost invisible upon the floor, stretched straight across the apartment to a door upon the far side.

There was no other way of which I knew, nor could I afford to ignore the advice to “follow the rope.” I must cross this room, but however I should accomplish it undetected with that old man in the very center of it baffled me.

Of course I might have sprung in upon him and with my bare hands silenced him forever, but I had heard enough to convince me that with him alive the knowledge that I had gained might serve me at some future moment, while should I kill him and another be stationed in his place Thurid would not come hither with Dejah Thoris, as was quite evidently his intention.

As I stood in the dark shadow of the tunnel’s end racking my brain for a feasible plan the while I watched, catlike, the old man’s every move, he took up the money-pouch and crossed to one end of the apartment, where, bending to his knees, he fumbled with a panel in the wall.

Instantly I guessed that here was the hiding place in which he hoarded his wealth, and while he bent there, his back toward me, I entered the chamber upon tiptoe, and with the utmost stealth essayed to reach the opposite side before he should complete his task and turn again toward the room’s center.

Scarcely thirty steps, all told, must I take, and yet it seemed to my overwrought imagination that that farther wall was miles away; but at last I reached it, nor once had I taken my eyes from the back of the old miser’s head.

He did not turn until my hand was upon the button that controlled the door through which my way led, and then he turned away from me as I passed through and gently closed the door.

For an instant I paused, my ear close to the panel, to learn if he had suspected aught, but as no sound of pursuit came from within I wheeled and made my way along the new corridor, following the rope, which I coiled and brought with me as I advanced.

But a short distance farther on I came to the rope’s end at a point where five corridors met. What was I to do? Which way should I turn? I was nonplused.
