Escape's "The Notebook" is set in the Dakota Terrritory during the Black Hills Gold Rush in the mid 1870's. It is a tale of two prospectors who are stalked by claim jumpers...and that's about all that happens until the end of the episode. "The Notebook" is a story about pursuit and, ultimately, escape, but does not include a happy ending. It isn't that kind of story.
"The Notebook" was transcribed under the direction of Antony Ellis from a story by William J. Radcliff. No short story under this title by that author can be found. So, it is possible that it was scripted for radio from an unpublished work.
As the episode opens, two prospectors, Robbie and Mac, have broken camp and are on their way to Deadwood to file their claim. Suddenly, a whiskered man in the distance shoots at them...and it isn't the first time. He wants their claim and he will kill to get it.
Mac asks Robbie if he is ready to kill protect their claim, but Robbie can't give him an answer. Is the gold worth it? The whiskered man and his boss seem to think so. They are relentless in their pursuit.
