In Cold Blood - S3.E12

Don Carlos comes to Bordertown to oversee the bounty hunter he has hired to eliminate Jack Craddock, but Jack intervenes by confiscating the money that was intended to pay the bounty. Unaware that she is placing Jack in danger, Marie returns the money to the Don in the hopes that he will leave town peacefully. Instead, he forwards the money to the killer, leading to a fatal shootout between the two men.
