S1·E11 Short Straw

Upset that Dan refuses to recind a 10 p.m. curfew he's put on all the saloons in town, the three saloon owners draw straws to see who gets the 'short straw'. That man is the one who is supposed to kill Marshall Troop. Instead, he hires a killer whom Dan knows and recognizes in the cafe. The rest of the show is spent trying to figure out who he's there to kill - and who paid him to do it.
