The Spectre of Lanyon Moor (audio story)

 was the ninth story in Big Finish's monthly range. It was written by Nicholas Pegg and featured Colin Baker as the Sixth Doctor, Maggie Stables as Evelyn and Nicholas Courtney as Brigadier Lethbridge-Stewart.

It was the first Doctor Who audio story to feature the Brigadier and the first "official" meeting of the Sixth Doctor and the Brigadier with the actors playing their characters. Nicholas Courtney had previously played the Brigadier in audio form in the two audio radio plays The Paradise of Death and The Ghosts of N-Space opposite Jon Pertwee and Elisabeth Sladen.
