Sapphire & Steel, Assignment 5
by Don Houghton & Anthony Read (ITV, 1981)
Different writers but the usual mix of otherworldliness and off-kilter intrigue as Sapphire & Steel investigate a 50-year timeslip with built-in murder mystery. The interdimensional operatives again prove remarkably ineffectual in employing their special powers, thereby stretching the story to six episodes.
