Again the newcomer rasped out his warning, and Gray, too, added his voice, saying: "Leave him to me, old man. This is my quarrel." As he spoke he moved around the end of the table, but the mantled figure halted him with an imperious jerk of the head. Without in the slightest diverting his steady gaze, Tom snapped: "Hands off, stranger! I won't have you buttin' in, either. I don't allow anybody to interfere with me when I'm eating." Gray was checked less by the exasperation, by the authority in the speaker's tone, than by the fact that the entire complexion of the affair had changed. The ruffian, who had entered so confidently, was no longer the aggressor; a mere look, a word, a gesture from this aged, unknown person had put him upon the defensive. More extraordinary still was the fact that his power of initiative was for the moment completely paralyzed, and that he was tortured by a deplorable indecision. He was furious, that was plain, nevertheless his anger had been halted in mid-flight, as it were; desperation battled with an inexplicable dread. He raised his hands now, but more in a gesture of surrender than of threat. "Don't come any closer," he cried, hoarsely. "Don't do it, I tell you! _Don't--do it!_'" There was no longer any thickness to his tongue; he spoke as one quite sober. When for the third time that malevolent voice repeated, "I don't allow anybody to interfere with me when I'm eating," the solitary onlooker felt an absurd desire to laugh. During intensely dramatic moments nervous laughter is near the surface, and there was something rigidly dramatic about the methodical, sidling advance of that man half crouched behind his overcoat. Tom, as he had been called, gave Gray the impression of Death itself marching slowly forward to drape that black shroud upon his cowering victim. Brief as had been the whole episode, already passers-by had halted, staring faces were glued to the front windows of the cafe. Well they might stare at those two tense figures, one advancing, the other retreating, as if to the measures of some slow dance. [Illustration: "DON'T COME ANY CLOSER. DON'T DO IT, I TELL YOU!"] But the tempo changed abruptly. The desperado's back brought up against the swinging kitchen door; it gave to his weight and decision was born of that instant. With a cry he flung himself backward, the spring door snapped to and swallowed him up with the speed of a camera shutter; then followed the sound of his heavy rushing footsteps. "Hell!" exclaimed the old man. "I had his buttons counted!" With the words he let fall his overcoat, and there, beneath it, Gray beheld what he had more than half suspected, what indeed was ample cause for the quarrelsome stranger's apprehension. Held close to the owner's body was what in the inelegant jargon of the West is known as a "dog leg." The weapon, a frontier Colt's of heavy caliber, was full cocked under the old man's thumb; the hand holding it was as steady as the blazing eyes above.
