Publisher's summary
A curse on this damned reef — and curse the Doctor who brought us here!

Drawn by the siren call of a distress beacon, the TARDIS crash-lands on an uncharted time reef. However, the Doctor, Nyssa and Brewster are not the only mariners marooned on this barren rock. Commander Gammades and his crew of returning war heroes have been similarly shipwrecked, as has the beautiful but mysterious Lady Vuyoki.

But there's something else here, too. A thing of darkness which crawls blindly across the surface of the reef hunting for prey: the Ruhk.

Cast

 * The Doctor - Peter Davison
 * Nyssa - Sarah Sutton
 * Thomas Brewster - John Pickard
 * Commander Gammades - Nicholas Farrell
 * Lady Vuyoki - Beth Chalmers
 * The Ruhk - Sean Biggerstaff
 * Lucor - Sean Connolly

Individuals

 * Lady Vuyoki lives inside a giant jar, which she referred to as her bridal urn. It has been in her family for generations.
 * While the TARDIS was in his possession, Brewster passed himself off as the Doctor.
 * Lucor gives the Doctor the nickname "Blondie." Even after his true identity is revealed, he continues to refer to him as such.
 * The Ruhk is a blind avian lifeform from another dimension which the crew of the Gamma believes feeds on carrion.
 * Brewster sold the crew of the Gamma the TARDIS' fault locator, conceptual geometer, food machine and power lens unit. It cost the crew most of the Gamma's treasure trove. The Doctor informs them, however, that this equipment will not function outside of the TARDIS. After selling them the equipment, Brewster departed in the TARDIS, marooning the Gamma's survivors on the Time Reef.
 * The Doctor uses baler twine to help make his way through the TARDIS.

TARDIS

 * Among the equipment rendered missing by Brewster's meddling with the TARDIS is a food machine, the fault locator, the conceptual geometer, temporal navigation unit and the power lens unit.
 * The Doctor accuses Brewster of interfering with the TARDIS' inner dimensions and is furious that Brewster is wearing his shirt, which he obtained from the TARDIS wardrobe.
 * Without the conceptual geometer, the internal dimensions of the TARDIS cannot be maintained. Its removal greatly destabilises the interior, and leads to its eventual collapse as the TARDIS arrives on the Time Reef, following the alarm on the conceptual geometer.

Continuity

 * From the Doctor and Nyssa's perspective, five months have passed since Brewster stole the TARDIS and marooned them in 1867. (AUDIO: The Haunting of Thomas Brewster)
 * The Doctor notes that the TARDIS' food machine (TV: The Daleks), fault locator (TV: The Edge of Destruction) and conceptual geometer (TV: The Horns of Nimon) are all missing.
