The Lost Secret

English teachers and students of a certain age may remember The Lost Secret, a BBC Education video course from 1986.

It tells the story of a man who has lost his memory and who encounters a gang, led by the sinister Professor Sline. The cast includes Miranda Richardson and Vladek Sheybal.

The course is aimed at lower-level students. There are 11 episodes of 13 minutes, each focusing on particular language points.

The videos are currently available on archive.org and YouTube.
