It’s 1967. The Cold War is chugging along nicely. Steed is driving a fellow agent and old school chum, Mark Crayford, to the border between East and West Germany. Uncharacteristically, Steed is wearing a flat cap instead of his usual bowler. Little does he know that his friend is about to turn traitor. Little does he know that his friend is about to try to kill him.
They get to the drop point. Steed goes towards the fence with Mark, who turns to announce his plans to defect. Then he takes a shot at Steed. Steed’s hat falls off as he flings himself the ground trying to escape Marks’ bullets. Steed shoots back, hitting Mark in the chest.
In “The Thirteenth Hole,” the bad guys are out on the links, pretending that they’re interested in their golf game. When they get to the thirteenth hole, they find an agent snooping around. Reed tells his caddy that he wants his “303” golf club. This turns out to be a rifle, with which Reed shoots and kills the agent.
Later, when Steed and Mrs Peel are heading out for their final showdown with the villains, Mrs Peel pulls a walking stick out of Steed’s golf bag. Steed says that it’s actually a sword stick, but later when they’re fighting in the villains’ hideout Steed discovers that he brought the wrong stick from home: this one is a plain walking stick, no shiny sharp objects included.
