From Tardis Wiki, the free Doctor Who reference
Spring-heeled Jack uses a psychic conduit on the Eighth Doctor. (DWM: The Curious Tale of Spring-Heeled Jack)
A psychic conduit was a form of mind probe that allowed the user to see the thoughts of another. Spring-heeled Jack used a psychic conduit on the Eighth Doctor. In his mind he saw Gallifrey, the TARDIS and Susan.
The Doctor turned the conduit around and saw inside his attacker's mind. He had visions of Jack's world ablaze. Penny Chapman separated the two when she attacked Jack with a gun. (DWM: The Curious Tale of Spring-Heeled Jack)
