Known as Quinn Martin's Tales of the Unexpected but released in the UK as Twist in the tale.
Every episode was a different story with often horror or supernatural elements. The pilot was a remake of cape fear - and probably the best version of this story. There was also a remake of the episode of the Invaders (also an earlier Quinn Martin tv series) and although all the episodes where fun, the one I remember fondly was 'A hand for Sonny Blue' about an American Football player that has a hand transplant. Unfortunately it has a mind of its own.
The twists were sometimes disappointing and you are left thinking WHAT? !!!! but that didn't stop you looking forward the next episode. Ran too short (8 episodes) and there were more episodes planned. Despite one of the most requested shows for a DVD release, this still remains something we are still waiting for. Several of the episodes were repeated on cable tv channels but nowadays it seems to be overlooked or forgotten. Pity, as 1970's telly at its best.
