Claws of the Klathi! (comic story)

Summary
The TARDIS materialises in the smoggy streets of Victorian London, near the home of gentleman scientist Nathaniel Derridge. Someone has been breaking into scientists' homes and stealing invaluable equipment, and when the Doctor learns that scorched bodies have been found near the docks, he decides to investigate with Derridge's help. They find an alien spaceship lying in the riverbed; it and its robot guardian are hidden from view by the smog. When they return to Derridge's home, they are greeted by a policeman with a strange story; Caval, the reptile boy from a nearby freak show, was caught stealing from a street vendor, and when he was knocked unconscious in the ensuing struggle his body began to glow. The Doctor realises that Caval is an alien in a healing coma, and when Caval recovers, he explains that his friends the Klathi have had him stealing equipment so they can repair their ship and escape from the Earth. But when Caval describes the ship's crystalline power source, the Doctor realises that it will kill thousands of people when the Klathi re-energise it. He, Caval and Derridge rush to the Great Exhibition, where the ruthless Klathi intend to use Osler's crystal fountain to energise the power unit; the Doctor stops them and saves the visitors to the Exhibition, but the Klathi escape, still intending to take off even though the launch of the ship will destroy London. The Doctor, Caval and Derridge pursue them back to the ship, where Caval finally acknowledges the Klathi's evil, and orders his robot Batella to stop them. Batella, confused by the conflicting instructions he has been given, stumbles into the ship and explodes, killing the Klathi. Caval returns to the freak show, which is now the only home he knows.
