Sapphire & Steel, Assignment 6
by P. J. Hammond (ITV, 1982)
The series’ much-vaunted 4-part conclusion. Hammond takes his characters out in style, concocting an eerie, unsettling scenario for Sapphire and Steel (and Silver) to unravel. Unfortunately, the trap’s convoluted outer layer proves unconnected to the springing of the more deadly trap within.
