The Banshee Raiders

They came out of the blackness of night, wailing like messengers of death, extracting life from the ex-vigilantes of Flintlock, Montana. Their death list had eight names on it, and only their own deaths can prevent them from killing those men. Clay Murdock had a reputation as a lawman and a tracker. He finds the last man murdered by the raiders. He knew their tracks were not from ghosts - even if they did vanish into thin air. Determined to stop the bloodshed, Clay discovers that one of the raiders might be a young woman - the very woman he's fallen in love with
