Jon Culshaw reads a thrilling novelisation of the 1976 audio adventure in which the Fourth Doctor and Sarah Jane face an aquatic menace.
A scientific expedition has disappeared from the bed of the Thames Estuary, where a giant meteorite had previously landed. Nearby, the Doctor and Sarah Jane are attacked by a vast, roaring creature.
The Doctor is reminded of his encounter with the marine denizens of the planet Pesca, and soon his worst fears are confirmed.
Strange meteorites are landing all over the world, and the Pescaton invasion has begun.
Jon Culshaw reads Victor Pemberton's much-expanded novelisation of his own original script, with accompanying sound design.
Reading produced by Morrison Ellis. Sound design by Oliver Denman. Executive producer for BBC Audiobooks: Michael Stevens
