"We have on Mars."

"It is an expression of the normal morbid interest in the horrifying," I said.

"There is really no justification, but the fact remains that I enjoy such tales. However, I have lost my interest now. I want to hear about you and Dejah Thoris and Carthoris, and what brought you here. It has been years since you have been back. I had given up all hope of ever seeing you again."

He shook his head, a little sadly I thought. "It is a long story, a story of love and loyalty, of hate and crime, a story of dripping swords, of strange places and strange people upon a stranger world. The living of it might have driven a weaker man to madness. To have one you love taken from you and not to know her fate!"

I did not have to ask whom he meant. It could be none other than the incomparable Dejah Thoris, Princess of Helium, and consort of John Carter, Warlord of Mars-the woman for whose deathless beauty a million swords had been kept red with blood on the dying planet for many a long year.

For a long time John Carter sat in silence staring at the floor. I knew that his thoughts were forty-three million miles away, and I was loath to interrupt them.

At last he spoke. "Human nature is alike everywhere," he said. He flicked the edge of the magazine lying on my bunk. "We think that we want to forget the tragedies of life, but we do not. If they momentarily pass us by and leave us in peace, we must conjure them again, either in our thoughts or through some such medium as you have adopted. As you find a grim pleasure in reading about them, so I find a grim pleasure in thinking about them.

"But my memories of that great tragedy are not all sad. There was high adventure, there was noble fighting; and in the end there was-but perhaps you would like to hear about it."

I told him that I would, so he told me the story that I have set down here in his own words, as nearly as I can recall them.

CHAPTER I. RAPAS THE ULSIO

Over nineteen hundred miles east of the Twin Cities of Helium, at about Lat. 30 degrees S., Lon. 172 degrees E., lies Zodanga. It has ever been a hotbed of sedition since the day that I led the fierce green hordes of Thark against it and, reducing it, added it to the Empire of Helium.

Within its frowning walls lives many a Zodangan who feels no loyalty for Helium; and here, too, have gathered numbers of the malcontents of the great empire ruled over by Tardos Mors, Jeddak of Helium. To Zodanga have migrated not a few of the personal and political enemies of the house of Tardos Mors and of his son-in-law, John Carter, Prince of Helium.

I visited the city as seldom as possible, as I had little love either for it or its people; but my duties called me there occasionally, principally because it was the headquarters of one of the most powerful guilds of assassins on Mars.

The land of my birth is cursed with its gangsters, its killers, and its kidnappers but these constitute but a slight menace as compared with the highly efficient organizations that flourish upon Mars. Here assassination is a profession; kidnaping, a fine art. Each has its guild, its laws, its customs, and its code of ethics; and so widespread are their ramifications that they seem inextricably interwoven into the entire social and political life of the planet.

For years I have been seeking to extirpate this noxious system, but the job has seemed a thankless and hopeless one. Entrenched behind age-old ramparts of habit and tradition, they occupy a position in the public consciousness that has cast a certain glamour of romance and honor upon them.

The kidnappers are not in such good odor, but among the more notorious assassins are men who hold much the same position in the esteem of the masses as do your great heroes of the prize ring and the baseball diamond.

Furthermore, in the war that I was waging upon them, I was also handicapped by the fact that I must fight almost alone, as even those of the red men of Mars who felt as I did upon the subject also believed that to take sides with me against the assassins would prove but another means for committing suicide. Yet I know that even this would not have deterred them, had they felt that there was any hope of eventual success.

That I had for so long escaped the keen blade of the assassin seemed little less than a miracle to them, and I presume that only my extreme self-confidence in my ability to take care of myself prevented me from holding the same view.

Dejah Thoris and my son, Carthoris, often counseled me to abandon the fight; but all my life I have been loath to admit defeat, nor ever have I willingly abandoned the chance for a good fight.

Certain types of killings upon Mars are punishable by death, and most of the killings of the assassins fell in such categories. So far, this was the only weapon that I had been able to use against them, and then not always successfully, for it was usually difficult to prove their crime, since even eyewitnesses feared to testify against them.

But I had gradually evolved and organized another means of combating them. This consisted of a secret organization of super-assassins. In other words, I had elected to fight the devil with fire.

When an assassination was reported, my organization acted in the role of detective to ferret out the murderer. Then it acted as judge and jury and eventually as executioner. Its every move was made in secret, but over the heart of each of its victims an «X» was cut with the sharp point of a dagger.

We usually struck quickly, if we could strike at all; and soon the public and the assassins learned to connect that «X» over the heart as the mark of the hand of justice falling upon the guilty; and I know that in a number of the larger cities of Helium we greatly reduced the death rate by assassination.
