Cheap Whiskey and Sad Women

Clint is asked by Bat Masterson to meet him in Louisville, Kentucky.  The Gunsmith arrives first, and while waiting for Bat to arrive, is asked by a local distillery owner to invest in his product. Even more, he'd like to put Clint's picture on the label. Clint is advised by a friend, Mad McCall, not to invest. Soon after, McCall is shot from ambush. Was the bullet meant for him or for Clint? And did it have anything to do with Clint's refusal? Clint wants to find out before they try again.
