Publisher's summary
Professor Nightshade - tea time terror for all the family, and the most loved show in Britain. But Professor Nightshade's days are long over, and Edmund Trevithick is now just an unemployed actor in a retirement home, fondly remembering his past.

It's the same through the entire village of Crook Marsham - people are falling prey to their memories. At first harmlessly, and then, the bodies begin to turn up.

The Doctor and Ace arrive on the scene - but, with the Doctor planning his retirement, it may be time for Professor Nightshade to solve one last case.

Deviations from the original novel

 * The prologue and the epilogue are not included.
 * Vijay Degun, a major supporting character in the novel, is omitted from the audio adaptation. Holly Kidd, Constable George Lowcock, Jack Prudhoe and Tim Medway are mentioned but do not appear.
 * In the audio adapation, the Doctor confirms that Susan is his granddaughter. In the novel, he remains silent when Ace asks who Susan is to him.
 * The Doctor uses his sonic screwdriver in the audio adaptation but he does not have one in the novel.
 * In the novel, Robin's stepmother, Betty Yeadon, is killed by the Sentience. In the audio adaptation, Betty is Robin's mother while Lawrence is his stepfather and she is implied to have been dead for many years.
 * In the novel, the Sentience manifested in the form of Alfred Beadle when it appears to his sister Betty Yeadon. In the audio adaptation, Alf is Lawrence Yeadon's brother.
 * Hawthorne is 55 years old in the novel. He is much younger in the audio adaptation as he was a schoolboy when Nightshade was first broadcast in the 1950s.
 * In the audio adaptation, Hawthorne is given a more sympathetic treatment than in the novel, in large part because the racist dimension of the character has been removed.
 * No details of Trevithick's family are revealed.
 * Hawthorne is killed by the Sentience in the novel but survives in the audio adaptation.
 * In the novel, the Doctor refuses to allow Ace to leave and materialises the TARDIS on an alien planet instead of returning her to Crook Marsham in 1968. In the audio adaptation, the Doctor does return Ace to Crook Marsham, but she begins to have second thoughts about leaving the TARDIS. The Doctor tells her that she is faced with a difficult decision, and the audio ends ambiguously with the Doctor going into the TARDIS and leaving Ace outside to decide if she will go with him or stay with Robin.
