Sent by the mysterious Kro’ka into a jungle environment, The Doctor, Charley and C’rizz get more than they bargained for especially as the spectre of death surrounds the harshly oppressive jungle environment The Doctor, Charley and C'rizz have found themselves in their continued hunt for the TARDIS. They soon find themselves upon a waterfall - much to the delight of Charley who it seems has faired much worse in their trek in the jungle.

Eighth Doctor

 Unbeknown to The Doctor and his two companions they are not completely alone. As well as finding a completely decomposed skeleton they are also being watched by a Major Koth the leader of a rebel training camp preparing itself for an oncoming war.

 Charley, in her attempts to recover from the effects of their trip through the jungle, becomes separated from The Doctor and C'rizz just when a team of soldiers, who are searching for Koth, escort The Doctor and her fellow companion away into some nearby caves. But Charley on watching all this from a hiding place finds herself in the company of a jaded-yet-broadminded scientist - which turns out to be fortunate as she has just been attacked by a deadly plant that results in a very painful cure.

 Exploring the caves The Doctor is mentally attacked when a powerful creature tries to connect with his mind with pure rage. Still being tracked by Major Koth The Doctor and the team of soldiers are they themselves taken captive when they become to close to Koth’s secret base.

 The Doctor and his companions soon learn that the respected authoritarian figure of Major Koth has withdrawn into the savage jungle after a command decision was taken not to inform him of the death of his family in an atrocious attack so he could continue to perform his duties to the best of his abilities without distraction. Koth therefore has turned away from his own civilisation.

 But not everything is what it seems at Major Koth's rebel training camp. Why does an underground river of blood turn suddenly into one of acid and why do dead soldiers decompose so quickly? Why has the blood of innocents been spilt and who really is the enemy? Could The Doctor this time be completely wrong in his deduction of current events? Charley and C'rizz think he is and as events unfold it seems that they might be right.

 The Doctor taking on an assumed identity to further his investigations on what Major Koth is really up to manages to gain the confidence of Koth’s loyal followers. But Koth instinctively sees The Doctor's weaknesses and uses them to turn The Doctor’s friends against him in pursuit of his goals. But other forces are having an effect on those in the caves preventing free thoughts and making everyone want to stay and not leave - even The Doctor seems at first to be effected and is acting against his normal character.

 When the extent of Major Koth's manipulation is finally revealed The Doctor learns that the cave system is not what it seems and that they are all in grave danger of either being eaten alive or being forced to murder each other for the pleasure of another.

 Forced to co-operate otherwise he will lose everything - his companions and his TARDIS - has The Doctor realised to late that amongst the dark caverns of this unknown world he has encountered a creature that he can’t defeat and that maybe he has finally met his match. Or will he and his companions be able to escape in the TARDIS?

 But maybe this is too much to ask for in the Divergent Universe especially when a very old foe is manipulating things…

On the Back Cover:

 

 Deep underground, an army of light prepares itself for the oncoming war.

 The Doctor's used to winning. Stumbling in, reading the face of the enemy, and then beating the odds… but what if this time he's got it wrong? Charley and C'rizz think he has.

 Stripped of all that is familiar, just who is The Doctor? Major Koth thinks he knows.

 Lost among the dark caverns of an unknown world, has The Doctor finally met his match?

 I ORIGINALLY WROTE THE SCRIPT for The Twilight Kingdom almost two years ago, in the summer of 2002. Memories of 11 September were still vivid

 Thanks, Mum.

 Not surprisingly, some of that fear and anxiety crept into the play you’re about to hear. Don’t get me wrong, there’s no deep message here or indeed any profound political statement being expressed, but grief is perhaps the most powerful of all emotions. It’s something that binds us all, and it’s remarkable how varied our responses can be...

 What I’m rather pompously trying to say is don’t expect a gag fest. However, in deference to the ghost of Doctor Who Past you will find at least one wobbly set -you’ll know it when you get to it.

 Finally a word of thanks to all at Big Finish - I was trying to recreate something of the spookiness that so grabbed me as a child. With an actor as terrific as Paul McGann in the lead, so ably assisted by India and Conrad, the dose thing really was to drop them all into hell...

 Will Shindler was introduced to the Big Finish team via two of its most popular authors, Paul Cornell and Robert Shearman. It was Rob who actually introduced Will to producer Gary Russell in a cafe in London’s Oxford Street and Will’s ideas immediately resonated with the producer’s plans for this third Eighth Doctor run.
