In the episode titled The Man Who Walked Behind from Incredible but True, we are introduced to Kathleen O'Rourke, who has a routine of walking down the narrow road known as Nohead Lownen to the village post office every Monday morning. On one particular June morning, she is approached by her neighbor, Molly Donovan, who expresses concern about her missing brother, Patrick. Molly asks Kathleen to check for any letters at the post office, and Kathleen readily agrees, not knowing that this seemingly mundane task will lead her into an unsettling experience.
