Dr. Who: Invisible Enemy: #93 / K9 Company: Girl's Best Friend

THE BRAIN OF MORBIUS The TARDIS is infiltrated by the Swarm - a space-borne intelligence that wishes to spread itself across the universe - and the Doctor is infected by its nucleus. The ship then materialises on Titan, one of the moons of Saturn, where the human occupants of a refuelling station have also been taken over. The Doctor eventually collapses as a result of his infection, but first manages to relay to Leela the coordinates of a local hospital asteroid. At the Bi-Al Foundation, based on the asteroid, Professor Marius clones the two time travellers, miniaturises the clones using the relative dimensional stabiliser from the TARDIS and then injects them into the Doctor's body in the hope that they can find and destroy the nucleus.K9 AND COMPANY: A GIRL'S BEST FRIEND Sarah pays a Christmas visit to her Aunt Lavinia's house in the village of Moreton Harwood.
