The Seventh Man by Max Brand

News of the Killing at Alder, as they call that night's slaughter to this day in the mountain-desert, traveled swiftly, and lost nothing of bulk and burden on the way; so that two days later, when Lee Haines went down for mail to the wretched little village in the valley, he heard the store-keeper retailing the story to an awe-stricken group. How the tale had crossed all the wild mountains which lay between in so brief a space no man could say, but first there ran a whisper and then a stir, and then half a dozen men came in at once, each with an elaboration of the theme more horrible than the last. The store-keeper culled the choicest fragments from every version, strung them together with a narrative of his own fertile invention, polished off the tale by a few rehearsals in his home, and then placed his product on the open market. The very first day he kept the store-room well filled from dawn until dark.

And this was the creation to which Lee Haines had to listen, impatient, sifting the chaff from the grains of truth. Down upon Alder, exactly at midnight, had ridden a cavalcade headed by that notorious, half-legendary man-slayer, Dan Barry -- Whistling Dan. While his crew of two-score hardened ruffians held the doors and the windows with leveled rifles, Barry had entered with a gun and a wolf -- a wild wolf, and had butchered ten men, wantonly. To add to the mystery, there was no motive of robbery for the crime. One sweeping visitation of death, and then the night-riders had rushed away. Nor was this all, for Sheriff Pete Glass, hearing of the tragedy, had ridden to Rickett, the county seat, and from this strategic point of vantage he was sending out a call for the most practised fighters on the mountain-desert. He wanted twenty men proved beyond the shadow of question for courage, endurance, speed, and surety in action.
