High Noon on Phobos

Blaze McGregor is a man of many talents. He's a raconteur, troubadour, retired gunfighter, and occasional bounty hunter--and he was down on his luck. His ship was a wreck, he had no money, he had no jobs lined up, and people all over the galaxy wanted him dead. So he'd propped himself up on a bar stool at Red Foster's tavern on Mars and was trying to drown his sorrows in fuzzy navels and get away from his troubles.
Then trouble found him. An old friend had taken up ranching on Phobos and was being plagued by some cattle rustlers calling themselves the Kinkaide Gang. Phobos could really use someone with Blaze's skills to teach these rustlers a lesson or two. There'd be some good money in it, if he could survive. Would he take the job? Well, what else is a down-on-his-luck retired gunfighter to do?
