Publisher's summary
The house on Fleming's Island had been left to rot. Ever since a strange and unexplained death soon after it was built, and plagued with troubling rumours about what lurked there, it remained empty and ignored for decades until the Cult moved in. As twenty people filled its many rooms, the eerie building seemed to be getting a new lease of life.

But now it is empty again. The cult found something in its corridors... and then vanished.

Trapped on the island one dark night, the Doctor, Tegan, Nyssa and Adric look into the building's mysteries, its stories of madness and death. Their only chance is to understand what terrible thing has been disturbed here... before it consumes them utterly.

Part one
In August 1981, students Imogen Frazer and Martin Tuck take part in research on Fleming's Island off the coast of Ireland and Martin starts repeatedly saying the letter "I". Imogen fails to return to England so, in December, her boyfriend Jerome Khan travels to Ireland and reports her disappearance Constable Robert DeValley, who knows the island as a place of evil and decides to travel there.

Although Tegan is now happy to travel in the TARDIS, Adric and Nyssa attempt to program the ship to take them to Heathrow Airport in 1981 as a test whilst the Doctor is reading Black Orchid in the library. They land on top of a cliff on Fleming's Island and, after the four travellers exit, the ship falls to the ground below and a storm hits. Looking for shelter, they go to a nearby mansion where Nyssa suffers from a psychic shock as her mind is momentarily flooded with numbers and voices.

The Doctor, Adric, Nyssa and Tegan find a number of computers which interest the Doctor, but Tegan is only concerned with making their way to the TARDIS. As the mansion seems to be empty, the Doctor and Adric look for a way to contact the outside world whilst Tegan stays with Nyssa, who starts repeatedly saying "I".
