Out today are four new adventures told by the Doctor's nearest and dearest - his assistants, his friends, his companions. With Polly and dinosaurs, Leela meeting the Second Doctor and Ruth Matheson saving the world with Zoe, these new stories aren't to be missed!

Four new adventures from the era of the Second Doctor await Jamie McCrimmon, Polly Wright, Ben Jackson, Leela and Zoe Heriot in Doctor Who The Companion Chronicles: The Second Doctor Volume Two – out now.

The Curator’s Egg by Julian Richards

Zoltan Clarkson (Eccentric Billionaire, Cybernetics Tycoon, Museum Curator) had a dream of a domestic dinosaur in every home. He bought the empty county of Dorset to work on this dream and develop cyborg dinosaur hybrids in a safe, contained environment.

With the Doctor and Ben chasing monsters at sea, Polly has only a socially awkward scientist and the world's friendliest dog to help her prevent the rise of the ultimate predators…

Dumb Waiter by Rob Nisbet

The Doctor and Victoria attend a civilised garden party. But their genial hostess, Mrs De Winter, is convinced that the garden conceals a secret; something about Carlos the head waiter who never speaks.

The hidden truth can be glimpsed by people less accustomed to the mask of politeness and cake. People like Jamie. And people like Leela, the mysterious warrior of the Seventeen…

The Iron Maid by John Pritchard

The TARDIS has arrived in France in the fourteenth century – a time of devastation and despair. In an empty church beside a crowded graveyard, Zoe meets a woman who claims to see a dreadful future waiting for the world.

The Tactics of Defeat by Tony Jones

In the rain-swept jungle of Belize, Captain Ruth Matheson and Zoe Heriot are both about to discover just what sacrifices they are prepared to make when faced with a seventeenth century threat that might just spell death for millions of innocent people.

Does the end justify the means? Sometimes winning feels like exactly like losing…
