Vintage 1996 BBC Radio Collection - Doctor Dr Who - The Ghosts Of N-Space Double Audio Cassette Set - Shop Stock Room Find. Released by BBC Enterprises in 1996 as part of their series of Dr Who on Audio Cassettes. This fantastic double audio cassette set features the story The Ghosts Of N-Space which sees Jon Pertwee return to the role of the third Doctor in this brand new adventure with Sarah Jane Smith (Liz Sladen) and the Brigadier (Nick Courtney) in this story by legendary producer Barry Letts. The Brigadier's ancient great uncle Mario seems unsurprised by the spectres which haunt his even more ancient Sicilian castle. But when the Doctor comes to investigate he finds himself faced with a danger as great as any he has yet encountered. Is the answer to be found in the past, in the corrupt alchemy of the black-hearted sorceror said to have been walled up alive for his evil deeds? Or must the Doctor - and the faithful Sarah Jane Smith - brave the realm of ghosts and face the very fiends of Hell? Includes the Limited Edition Luminous Glow In The Dark Sleeve.
