Perceptions (comic story)

Summary
The Doctor and his friends Ssard and Stacy Townsend, arrive in Victorian London, where they discover a spaceship which is invisible to the people of the time. They meet the ship's inhabitant P'fer'd, who is an Equinoid. He resembles a gaudily-colored horse. P'fer'd tells the Doctor that his wife M'rek'd is missing. Stacy, along with some street urchins rescue M'rek'd from a freak show. However the owner of the freak show is not himself Human, but a shape-shifting alien and Stacy and the urchins are attacked. P'fer'd is re-united with M'rek'd and the Doctor and Ssard with Stacy... apparently.
