Deviations from televised story

 * The Shadow is an extra-dimensional ghost resurrected by the Black Guardian from one of the Doctor's enemies.
 * The Shadow's planet is an asteroid that resembles a medieval castle on the inside.
 * The planet is littered with trap doors.
 * The Doctor argues that the brief moment the Key was complete, the real White Guardian would have sorted everything out.
 * Drax mentions The Doctor's exile to Earth. He also mentions purchasing a second-hand TARDIS instead of stealing one, like the Doctor and their other classmates had done, and went into repair and maintenance.

Writing and publishing notes

 * This story was released as an audiobook read by John Leeson.
 * Producer John Nathan-Turner thought the cover artwork poor.
 * Second and final appearance of the Mary Tamm version of Romana on a Target range cover and the only one based on a photo reference. It was also the last appearance of any incarnation of Romana on a Target novelisation as Lalla Ward's image did not appear on any of the first editions of the Target novels featuring her version of Romana (although she was featured on later editions of some books).
