"The trainer at a stables is involved in doping and Gideon appears at a race meeting.

Episode 25: The Rhyme and the Reason
"A couple of teenagers have to catch the bus home from a day in the country after their scooter is wrecked by bikers. VOT568, an AEC Reliance/Duple miraculously appears on service to 'Blackdown' - filming could have been around Denham - I don't know where ITC filmed. There is no evidence of ownership but VOT was new to Bakers, Bordon in 1959 - one of a pair, the other being VOT678." (noted by Stuart Turner, screencap by stronghold)
