On hearing this, you may be sure I drew closer to the table, and looked over the shoulders of the men at the map below.

"As you see," said the lecturer, with renewed interest as he observed this addition to his audience, "it started in Constantinople, made its appearance next in Southern Russia and the Balkan States. Two days later a case was notified from Vienna and another in Prague. Berlin was the next city visited, then Wittenberg, then Hamburg. France did not become infected until some days later, and then the individual who brought it was proved to have arrived the day before from Berlin. Yesterday, according to the official returns, there were twelve hundred cases in France, eighteen thousand in Austria, sixteen thousand in Germany—of which Hamburg alone contributes five thousand three hundred and fifty—while in Italy there have been three thousand four hundred, in Spain and Portugal only two hundred and thirty, while Turkey and Russia have forty-five thousand, and thirty-seven thousand three hundred and eighty, respectively. Greece returns seventeen thousand six hundred and twenty, Holland seven thousand two hundred and sixty-four, Belgium nine thousand five hundred and twenty-three, while Denmark completes the total of Europe with four thousand two hundred and twenty-one. The inferences to be drawn from these figures are apparent. The total number of deaths upon the Continent up to midnight last night was one hundred and fifty-nine thousand eight hundred and thirty-eight. The nations most seriously affected are Turkey and the countries immediately surrounding her, namely, Greece, Russia, and Austria. Germany follows next, though why Hamburg should contribute such a large proportion as five thousand three hundred and fifty I must admit it is difficult to see. England hitherto has stood aloof; now, however, it has broken out in London, and three hundred and seventy-five cases have been notified up to eight o'clock this morning."

On hearing this, the men standing round him turned pale and shuffled uneasily upon their feet. As for myself, I might have been changed to stone, so cold and so incapable of moving was I. It was as if a bandage had suddenly been removed from my eyes, enabling me to see everything plainly and in its proper light.

"The returns for our own country," continued this indefatigable statistician, without noticing my condition, "are as interesting as those from the Continent. I have filed everything already published, and have applied the result to this map of London. The two cases that occurred in Norfolk, the porter in Norwich, and the stationmaster at Tebworth Junction, I omit, for the reason that they tell us nothing. Of the cases notified in this city, careful inquiries on the part of the authorities have elicited the information that twenty-five spent the evening at the Antiquarian Club last night, seventy-one at the Fancy Dress Ball at Covent Garden, while, strangely enough, no less than thirty-seven can be proved to have been among the guests of the Duchess of Amersham at her ball in Carlton House Terrace. The others are more difficult to account for, being made up of costermongers, homeless vagrants, street hawkers, and others of the same class."

I could bear no more, but stumbled from the room like a drunken man out into the hall beyond. A servant, thinking I was ill, hastened to inquire if he could be of any assistance to me.

"Get me a cab," I faltered huskily.

The man ran into the street and blew his whistle. A hansom drove up, and I made my way into the street and scrambled into it, scarcely knowing how I managed it, and then fell back upon the cushions as if I were in a fit. The cab sped along the streets, threaded its way in and out of the traffic with a dexterity and a solicitude for my safety that was a more biting sarcasm than any lips could utter. What was my safety to me now? Knowing what I knew, I had better, far better, be dead.

The dreadful secret was out. In less than five minutes the mystery of two months had been solved. Now I knew the meaning of the spot I had discovered upon my arm on the morning following my terrible adventure in the Pyramid; now I could understand my illness in the desert, and the sudden death of the poor Arab who had nursed me. In the light of this terrible truth, everything was as clear as daylight, and all I wanted was to get back to Park Lane and find myself face to face with Pharos, in order that I might tax him with it, and afterwards go forth and publish his infamy to the world. Fast as the man was driving, he could not make his horse go fast enough for me. Though at first my blood had been as cold as ice, it now raced through my veins like liquid fire. A feverish nervousness had seized me, and for the time being I was little better than a madman. Regardless of the passers-by, conscious only of the vile part I had been induced to play—unwittingly, it is true—in his unbelievable wickedness, I urged the driver to greater speed. At last, after what seemed an eternity, we reached our destination. I alighted, and, as I had done in Hamburg, paid the cabman with the first money I took from my pocket, and then went up the steps and entered the house. By this time the all-consuming fire of impatience which had succeeded the icy coldness of the first discovery had left me, and was succeeded by a strange, unnatural calm, in which I seemed to be myself, and yet to be standing at a distance, watching myself. In a voice that I scarcely recognised, I inquired from the butler where I could find his master. He informed me that he was in the drawing-room, and I accordingly went thither in search of him. I had not the least notion of what I was going to say to him when I found him, or how I should say it, but I had to relieve my mind of the weight it was carrying, and then——Why, after that, nothing would matter. I opened the door and entered the room. The sunshine was streaming in through the windows at the further end, falling upon the elegant furniture, the embroideries and draperies, the china, and the hundred-and-one knick-knacks that go to make up a fashionable drawing-room. Of Pharos, however, there was no sign. In place of him Valerie rose from a chair by the window and greeted me with a little exclamation of delight. Then, seeing the look upon my face, and the deadly pallor of my complexion, she must have realised that something serious had happened to me, for she ran forward and took my hands in hers.

"My darling!" she cried, with a look of terror upon her face, "what has happened? Tell me, for pity's sake, for your face terrifies me!"

The pressure of her hands and the sight of those beautiful frightened eyes gazing up into mine cut me to the heart. Overwhelmed with sorrow as I was, she alone of all the world could soothe me and alleviate the agony I was suffering. It was not possible, however, that I could avail myself of her sympathy. I was dishonoured enough already, without seeking to dishonour her. Here our love must end. For the future I should be an outcast, a social leper, carrying with me to my grave the knowledge of the curse I had brought upon my fellow men. I tried to put her from me, but she would not be denied.
