The Fourth Doctor (Tom Baker) returns alongside his companions Leela (Louise Jameson) and K9 (John Leeson) for a box set of two brand-new full-cast audio adventures from Big Finish Productions. 

In the first story, the two-part Conspiracy of Silence, the TARDIS crew are joined by the Brigadier (Jon Culshaw) as they investigate mysterious disappearances on a remote oil rig. The rig turns out to be infested by a terrifying enemy – though no one can remember them for long – the Silence (Nicholas Briggs). 

The second story in the box set is a four-part historical epic, The Last Queen of the Nile, in which the Doctor takes his companions on a trip to ancient Egypt. But this is no holiday, as they find Cleopatra’s realm on the brink of war. 

Pippa Bennett-Warner (Gangs of London) guest stars as Queen Cleopatra, alongside Michael Lumsden (The Archers) as Mark Anthony and Blake Ritson (The Gilded Age) as Octavian Caesar. 

Doctor Who – The Fourth Doctor Adventures: The Last Queen of the Nile is now available to pre-order from just £19.99 (download to own) or £24.99 (download to own + collector’s edition 3-disc CD box set) exclusively here. Please note: the collector’s edition CD box set is strictly limited to 1,500 copies and will not be repressed. 

The Fourth Doctor’s exciting new adventures are detailed below.  

Conspiracy of Silence by Jonathan Morris

Something happened to the oil rig. Something so swift and unexpected that the one hundred and fifty people aboard couldn’t summon help. Everyone who has tried to investigate has disappeared. 

So now the Brigadier is sending the Doctor and Leela. But is there anything to find there? Or is there nothing to be found there? No-one on board... but the Silence. 

The Last Queen of the Nile by David K Barnes 

The TARDIS lands a few miles from Alexandria in Egypt, where the Doctor, Leela and K9 encounter Mark Antony, returning from a military campaign. As he joins Cleopatra, they realise they are about to witness one of the most famous romances in history. 

But this romance threatens the power of Rome, where the ambitious Octavian Caesar is attempting to convince the Senate to declare war on the Queen of the Nile. A tragedy of Shakespearean proportions is about to unfold – and the time travellers are trapped in the middle. 

Producer David Richardson said: “It’s been a joy to bring the Brigadier back into the Doctor’s life this season, and in Conspiracy of Silence, he joins the Doctor, Leela and K9 on an adventure that is unforgettable. Or, given that the Silence are involved, can that even be possible? 

“And Last Queen of the Nile is a belting historical story by the genius writer David K Barnes, as the TARDIS crew encounter Cleopatra and Mark Antony in Egypt. It’s a story packed with peril, incident and drama, and a huge two-parter to end the season on.” 

Writer David K Barnes added: “I was always thrilled by those old Hollywood epics like Spartacus, Ben-Hur, and Cleopatra – those huge sets, all those costumes, lots of thesps strutting about with deliciously florid dialogue. I really loved all that and always wanted to see Doctor Who do that story. 

“And, I really like putting Leela into historical periods. The Doctor is almost godlike, stands back, gets involved in chats and jokes, but still has that Time Lord detachment. Leela doesn’t understand our history, yet she’s very much a part of it. If you put Steven or Vicki or Harry into a historical like this, they’d be horrified by the bloodshed, but Leela just gets on with it and gets straight through to the heart of the story.”
