Synopsis for Buck Marshall: "Death Message"
The sheriff introduces Buck to Vanter, a rancher whose partner, Hanser, was murdered. The two ranchers owned the Diamond V range. Their borders were right next to the Rolling N ranch which often led to clashes, due to Hanser's refusal to sell the land. Buck is shown into Hanser's office, where he was shot while reading the paper. The bullet traveled upward through the victim's shoulder blade, no one outside had heard anything. On the desk, Buck notices someone had made pencil marks in the margins of the newspaper. He takes it with him. Vanter said that they had only owned the ranch for a year. Before then, Hanser was a telegraph operator. Buck rides out to the Rolling N territory, spending the night at a hotel. Inside he sees Lefty Logan, an ex-con, whom he is told by the clerk has been working for the Rolling N and had been staying at a camp up in Gopher Valley for the past few months. Buck has his next lead.
In Gopher Valley, Buck finds a cabin where Lefty was staying and stakes it out. The first day, Lefty leaves in the morning to make his rounds, and no sign of him is seen until dark. Buck becomes suspicious, so on day two he follows him at a distance. The trail eventually leads out of the woods to an open field, so Buck hangs back and watches. Logan disappears into an arroyo. Buck is about to follow when a bullet whizzes past his head. He rolls behind a boulder and fires a return shot. Waiting a few moments to ensure that his attacker is dead, Buck continues to follow Logan's trail. A camp is set up in the gully, Logan and another man are loading bags of chopped steer meat onto saddles. The bags, Buck noticed, are marked with the Diamond V symbol. He gains the high ground from a ledge just above the men and holds them up.
The sheriff gets a surprise visit later that day as Buck brings the two men into his office. Logan belongs to a gang that supplies shifty meat packers that wish to remain off the record. The sheriff tells Buck that his boys just found Vanter's body an hour ago. With a bullet in his head. Buck deduces that Vanter was the one who had shot at him before. After some pushing, Logan confirms that Vantor had hired them to rustle the steer off of Diamond V's ranch. Vanter had made a deal with Rolling N, to try to force Hanser to sell the land. Buck took out the newspaper from before. He pointed at the marks and explained that Hanser's experience as a telegraph operator helped him leave a dying message. When decoded, it read "Vanter shot me."
