It was cold comfort. That the man Larby was following me I was confident, and that he meant to rob me I was at first convinced. Small solace, therefore, in the thought that if the worst befell me, and my boy at home died for want of his father, who lay robbed and murdered in those desolate wastes, my Government would exact a claim in paltry dollars.

My next thought was that the man was merely watching me out of the country. That he was aware that I knew his secret was only too certain; that he had betrayed my knowledge to the authorities at the capital after I had parted from them was more than probable, and it was not impossible that the very men who had taken bribes of me had in their turn bribed him that he might follow me and see that I did not inform the Ministers and Consuls of foreign countries of the murder of the American in the streets of Fez.

That theory partly reconciled me to the man's presence: Let him watch. His constant company was in its tormenting way my best security. I should go to no Minister, and no Consul should see me. I had too much reason to think of my own living affairs to busy myself with those of the dead American.

But such poor unction as this reflection brought me was dissipated by a second thought. What security for the man himself, or for the authorities who might have bribed him—or perhaps menaced him—to watch me would lie in the fact that I had passed out of the country without revealing the facts of the crime which I had witnessed? Safely back in England, I might tell all with safety. Once let me leave Morocco with their secret in my breast, and both the penalties these people dreaded might be upon them. Merely to watch me was wasted labor. They meant to do more, or they would have done nothing.

Thinking so, another idea took possession of me with a shock of terror—the man was following me to kill me as the sole Christian witness of the crime that had been committed. By the light of that theory everything became plain. When I visited the Kasbah nothing was known of my acquaintance with the murdered man. My bribes were taken, and I was allowed to leave Fez in spite of public orders. But then came Larby with alarming intelligence. I had been a friend of the American, and had been seen to speak with him in the public streets. Perhaps Larby himself had seen me, or perhaps my own guide, Alee, had betrayed me to his friend and "brother." At that the Kaid or his Kaleefa had raised their eyebrows and sworn at each other for simpletons and fools. To think that the very man who had intended to betray them had come with an innocent face and a tale of a sick child in England! To think that they had suffered him to slip through their fingers and leave them some paltry bribes of fifty pounds! Fifty pounds taken by stealth against twenty thousand dollars to be plumped down after the Christian had told his story! These Nazarenes were so subtle, and the sons of Ishmael were so simple. But diamond cut diamond. Everything was not lost. One hundred and twenty-five miles this Christian had still to travel before he could sail from Barbary, and not another Christian could he encounter on that journey. Then up, Larby, and after him! God make your way easy! Remember, Larby, remember, good fellow, it is not only the pockets of the people of Fez that are in danger if that Christian should escape. Let him leave the Gharb alive, and your own neck is in peril. You were the spy, you were the informer, you were the hotheaded madman who led the attack that ended in the spilling of Christian blood. If the Sultan should have to pay twenty thousand dollars to the Minister for America at Tangier for the life of this dead dog whom we have grubbed into the earth in a garden, if the Basha of Fez should have to pay forty thousand dollars to the Sultan, if the people should have to pay eighty thousand dollars to the Basha, then you, Larby, you in your turn will have to pay with your life to the people. It is your life against the life of the Christian. So follow him, watch him, silence him, he knows your secret—away!

Such was my notion of what happened at the Kasbah of Fez after I had passed the gates of the city. It was a wild vision, but to my distempered imagination it seemed to be a plausible theory. And now Larby, the spy upon the American, Larby, my assassin-elect, Larby, who to save his own life must take mine, Larby was with me, was beside me, was behind me constantly!

God help you, my son, God help you! Larby! O Larby! Again, again!

What was I to do? Open my heart to Larby; to tell him it was a blunder; that I meant no man mischief; that I was merely hastening back to my sick boy, who was dying for want of me? That was impossible; Larby would laugh in my face, and still follow me. Bribe him? That was useless; Larby would take my money and make the surer of his victim. It was a difficult problem; but at length I hit on a solution. Father, you will pity me for a fool when you hear it. I would bargain with Larby as Faust bargained with the devil. He should give me two weeks of life, and come with me to England. I should do my work here, and Larby should never leave my side. My boy's life should be saved by that operation, which I alone knew how to perform. After that Larby and I should square accounts together. He should have all the money I had in the world, and the passport of my name and influence for his return to his own country. I should write a confession of suicide, and then—and then—only then—at home—here in my own room—Larby should kill me in order to satisfy himself that his own secret and the secret of his people must be safe forever.

It was a mad dream, but what dream of dear life is not mad that comes to the man whom death dogs like a bloodhound? And mad as it was I tried to make it come true. The man was constantly near me, and on the third morning of our journey I drew up sharply, and said:

"Larby!"
