The final part of my reconstruction of this mostly missing Who serial, made using stills, video clips and the surviving soundtrack (narrated by Anneke Wills).
I would like to thank Chuckberryisthecoolest for his help in sourcing high-quality clips for this reconstruction.
The surviving Episode 3 is available on DVD in the Lost in Time box set. The narrated soundtrack is available on CD from BBC Audio. Support the BBC releases!
