'The Medusa Strain' (4 Parts) by Brian Finch and Roger Price

Floating in space for hundreds of years later, Jedikiah is eventually found by a spaceship, and repaired by its captain, Rabowski. Meanwhile, in the present day, Stephen is trying unsuccessfully to develop a photograph of something he saw in Hyperspace. Curious, Carol and Stephen leave John, Kenny and Ginge, and jaunt into Hyperspace to see if they can locate anything unusual. Back on the spaceship, Robowski shows Jedikiah his captive - Peter, whose telepathic abilities are being negated by an alien creature known as a Medusa. Jedikiah tricks Peter into operating Rabowski's Time Key, and they travel back to the Tower of London on Twentieth Century Earth, and steal the Crown Jewels. When Carol and Stephen jaunt back to the Lab, they find that everyone is frozen; the two of them then find Jedikiah, Rabowski and Peter at the Tower of London, but Carol is kidnapped and taken back to Rabowski’s spaceship in the future, while on Earth, everyone comes back to life. Peter refuses to operate the Time Key again, so Jedikiah and Rabowski put Carol into the airlock and start pumping the air out, in order to force the boy to acquiesce. Peter is forced to operate the Key, but insists that he be able to use his telepathy to help in the task. Jedikiah lets him, and Peter manages to contact the Tomorrow People, telling them where they he and Carol being held. John and Stephen jaunt into Hyperspace to look for the spaceship, while Rabowski, Jedikiah and the Medusa use the Time Key to go to the underground tunnels near the Lab. Rabowski captures Ginge, but the biker manages to push the Medusa onto the electrified rail lines, killing it. Ginge is then taken back to the spaceship. John and Stephen find the spaceship in Hyperspace, but are shot by the ship’s laser. Tim jaunts them back to the Lab, where ‘he’ and Kenny use an experimental technique to bring them back to life. Jedikiah turns against Rabowski, and in a struggle the Time Key is damaged. Rabowski makes his way to where Carol, Peter and Ginge are imprisoned, and Jedikiah turns the air and heat off. John and Stephen wake up, but they and Kenny are very weak, so they have to sleep to regain their strength. Jedikiah restores life support, locks up Rabowski and takes Peter to repair the Time Key. But Peter booby-traps the Time Key, and releases Carol and Rabowski from their cages. Attempting to escape, Jedikiah and Rabowski fight, but are transported by the Time Key to the surface of Mercury. Peter then uses the Time Key to return everyone to their right time-zones.
