He ate well, if simply, and treated himself to a small bottle of a noted champagne. At half-past seven, meaning to give Devar ten minutes' grace, he ordered coffee and a glass of green Chartreuse. As a time-killer, there is no liqueur more potent, but, regarded in the light of subsequent occurrences, it would be hard to say exactly how far the cunning monkish decoction helped in determining his wayward actions. Undoubtedly, some fantastic influence carried him beyond those bounds of calm self-possession within which everyone who knew John Delancy Curtis would have expected to find him. His subsequent light-headedness, his placid acceptance of a mad romance as the one thing that was inevitable, his ready yielding to impulse, his no less stubborn refusal to return to the beaten path of common sense—these unlikely traits in a character gifted with the New England dourness of purpose can only be explained, if at all, as arising from some unsuspected hereditary streak of knight-errantry brought into sudden and exotic life by the good wines of France.

Be that as it may, at twenty minutes to eight he paid what he owed, lighted a cigar, donned his hat, and, still carrying the overcoat, was walking to the office to leave word about the key, when his attention was attracted by the peculiar behavior of the man who had pushed against him at the cigar counter.

This person, apparently obeying a signal from another man of his own type who had just emerged from the elevator, hastened from the café, and the two ran to the door. Now, the weather had been mild during the afternoon, and the revolving shutters of the doorway were folded back to allow of the overheated hall being cooled. A porter stood there, and it was ascertained afterwards that, noticing a certain air of flurry and confusion about the foreigners, he asked if they wanted a taxi. They gave no heed, but continued to gaze up and down the street, as though they awaited someone. Equally did they seem to expect, or dread, an apparition from the hotel. It would have been hard to pick out, at that instant, two persons more singularly ill at ease in all New York.

Curtis saw that the clerk, now at his desk, was engaged with a lady, so he strolled to the door, being rather interested in the excited antics of the pair on the sidewalk. He had just passed through the door when an automobile dashed up, and he fancied, though he could not be quite sure in the half-light, that the chauffeur nodded to the waiting men. The porter opened the door of the automobile, and a young man in evening dress, and carrying an overcoat, leaped out. Obviously, he was in a desperate hurry, and Curtis heard him say in French:

"Don't stop the engine, Anatole. I shall be but one moment."

At that instant the two foreigners sprang at him. One, swinging the porter off his feet, seized the newcomer's right arm, and, helped by his comrade, endeavored to force him back into the vehicle. The effort failed, however, so the second desperado drew a knife and plunged it deliberately into the unfortunate man's neck. It was a fearsome stroke, intended both to silence and to kill, and, with a gurgling cry, its victim collapsed in the grip of his assailants.

Curtis, though almost stupefied by the suddenness of the crime, did not hesitate a second when he caught the venomous gleam of the knife. Throwing aside his coat, he rushed forward, but he had to cross the whole width of the pavement, and the murderers, realizing that the capture of one or both was imminent, thrust the inert body in his way. The chauffeur, who must have seen all that happened, had already started the car, the two men scrambled into it, and all that Curtis could do was to run after it and shout frantically to the driver of a taxi coming in the opposite direction to turn his vehicle and block the roadway.

The man understood, but was naturally slow to risk a sharp collision merely at the order of an excited gentleman in evening dress. He stopped quickly enough, but, by the time his help was available, pursuit was hopeless; the one thing Curtis could do he had done—while running up the street he had deciphered the number of the car, X24-305.

Before Curtis rejoined the dazed hall-porter a small crowd had gathered, and it was difficult to get near the body lying on the curb. A man picked up an overcoat, and Curtis, cool and clear-headed now, took it, and appealed to him, if he knew where the nearest doctor lived, to run thither at top speed. The man obeyed him instantly.

"Meanwhile, let me see to the poor fellow," he said. "I am not a doctor, but I know enough about wounds to say whether those scoundrels have killed him or not."
