It's been confirmed that BBC Four will be showing The Hand of Fear as a tribute to the late Elisabeth Sladen.
The story was first broadcast in 1976 and marked Sarah Jane Smith's initial departure from the series.
It was the last time Elisabeth Sladen starred opposite Tom Baker (the Fourth Doctor) in Doctor Who and is possibly best remembered for its touching farewell scene, later echoed in The Sarah Jane Adventures.
Episode one of The Hand of Fear will be shown at 7.40pm on Monday 9 May on BBC Four. Episode two will follow immediately and you can catch episode three the next day on the same channel at 7.40pm. Again, it will be followed immediately by the next and final episode.
