These old familiar sounds that are so distinctive of green Martian life sent a thrill of pleasure surging through me. It was as one might feel on coming home after a long absence. It was amid such sounds that I had first courted the incomparable Dejah Thoris in the age-old marble halls of the dead city of Korad.
As I stood in the shadows at the far corner of the first square which housed members of the horde, I saw warriors emerging from several of the buildings. They all went in the same direction, toward a great building which stood in the centre of the plaza. My knowledge of green Martian customs convinced me that this was either the quarters of the principal chieftain or contained the audience chamber wherein the Jeddak met his jeds and lesser chieftains. In either event, it was evident that something was afoot which might have a bearing on the recent capture of Tars Tarkas.
To reach this building, which I now felt it imperative that I do, I must needs traverse the entire length of one square and cross a broad avenue and a portion of the plaza. From the noises of the animals which came from every courtyard about me, I knew that there were many people in the surrounding buildings-probably several communities of the great horde of the Warhoons of the South.
To pass undetected among all these people was in itself a difficult task, but if I was to find and rescue the great Thark I must expect even more formidable obstacles before success could be mine. I had entered the city from the south and now stood on the corner of the avenue through which I had passed and the first intersecting avenue south of the plaza. The buildings upon the south side of this square did not appear to be inhabited, as I could see no lights, and so I decided to gain the inner courtyard through one of them.
Nothing occurred to interrupt my progress through the deserted pile I chose, and I came into the inner court close to the rear walls of the east buildings without detection. Within the court a great herd of thoats and zitidars moved restlessly about, cropping the moss-like ochre vegetation which overgrows practically the entire uncultivated area of Mars. What breeze there was came from the north-west, so there was little danger that the beasts would scent me. Had they, their squealing and grunting would have grown to such a volume as to attract the attention of the warriors within the buildings.
Close to the east wall, beneath the overhanging balconies of the second floors, I crept in dense shadows the full length of the courtyard, until I came to the buildings at the north end. These were lighted for about three floors up, but above the third floor all was dark.
To pass through the lighted rooms was, of course, out of the question, since they swarmed with green Martian men and women. My only path lay through the upper floors, and to gain these it was necessary to scale the face of the wall. The reaching of the balcony of the second floor was a matter of easy accomplishment-an agile leap gave my hands a grasp upon the stone hand-rail above. In another instant I had drawn myself upon the balcony.
Here through the open windows I saw the green folk squatting upon their sleeping silks and furs, grunting an occasional monosyllable, which, in connection with their wondrous telepathic powers, is ample for their conversational requirements. As I drew closer to listen to their words a warrior entered the room from the hall beyond.
"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.
I had naturally assumed that they would return with Tars Tarkas the same way that they had come, which would have carried them away from me; but, to my chagrin, they wheeled directly in my direction as they left the room. There was nothing for me but to hasten on in advance and keep out of the light of their torch. I dared not attempt to halt in the darkness of any of the many intersecting corridors, for I knew nothing of the direction they might take. Chance was as likely as not to carry me into the very corridor they might choose to enter.
The sensation of moving rapidly through these dark passages was far from reassuring. I knew not at what moment I might plunge headlong into some terrible pit or meet with some of the ghoulish creatures that inhabit these lower worlds beneath the dead cities of dying Mars. There filtered to me a faint radiance from the torch of the men behind-just enough to permit me to trace the direction of the winding passageways directly before me, and so keep me from dashing myself against the walls at the turns.
Presently I came to a place where five corridors diverged from a common point. I had hastened along one of them for some little distance when suddenly the faint light of the torch disappeared from behind me. I paused to listen for sounds of the party behind me, but the silence was as utter as the silence of the tomb.
Quickly I realized that the warriors had taken one of the other corridors with their prisoner, and so I hastened back with a feeling of considerable relief to take up a much safer and more desirable position behind them. It was much slower work returning, however, than it had been coming, for now the darkness was as utter as the silence.
