"Come, Tan Gama," he cried, "we are to take the Thark before Kab Kadja. Bring another with you."

The warrior addressed arose and, beckoning to a fellow squatting near, the three turned and left the apartment.

If I could but follow them the chance might come to free Tars Tarkas at once. At least I would learn the location of his prison.

At my right was a door leading from the balcony into the building. It was at the end of an unlighted hall, and on the impulse of the moment I stepped within. The hall was broad and led straight through to the front of the building. On either side were the doorways of the various apartments which lined it.

I had no more than entered the corridor than I saw the three warriors at the other end—those whom I had just seen leaving the apartment. Then a turn to the right took them from my sight again. Quickly I hastened along the hallway in pursuit. My gait was reckless, but I felt that Fate had been kind indeed to throw such an opportunity within my grasp, and I could not afford to allow it to elude me now.

At the far end of the corridor I found a spiral stairway leading to the floors above and below. The three had evidently left the floor by this avenue. That they had gone down and not up I was sure from my knowledge of these ancient buildings and the methods of the Warhoons.

I myself had once been a prisoner of the cruel hordes of northern Warhoon, and the memory of the underground dungeon in which I lay still is vivid in my memory. And so I felt certain that Tars Tarkas lay in the dark pits beneath some nearby building, and that in that direction I should find the trail of the three warriors leading to his cell.

Nor was I wrong. At the bottom of the runway, or rather at the landing on the floor below, I saw that the shaft descended into the pits beneath, and as I glanced down the flickering light of a torch revealed the presence of the three I was trailing.

Down they went toward the pits beneath the structure, and at a safe distance behind I followed the flicker of their torch. The way led through a maze of tortuous corridors, unlighted save for the wavering light they carried. We had gone perhaps a hundred yards when the party turned abruptly through a doorway at their right. I hastened on as rapidly as I dared through the darkness until I reached the point at which they had left the corridor. There, through an open door, I saw them removing the chains that secured the great Thark, Tars Tarkas, to the wall.

Hustling him roughly between them, they came immediately from the chamber, so quickly in fact that I was near to being apprehended. But I managed to run along the corridor in the direction I had been going in my pursuit of them far enough to be without the radius of their meagre light as they emerged from the cell.
