Listen for: Kent working out the position of the sun to find the right spot for the silver arrow, and the stranger who is revealed to be Bart Cummings.
Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
