It's the end of everything! Two renegades join forces to face an ancient conspiracy in Big Finish's blockbuster release, starring Sylvester McCoy, Geoffrey Beevers and Alex Macqueen.

The Doctor Who Main Range brings you a new full-cast adventure every month, starring one of the original actors to play the Doctor on television! Featuring fantastic new creations or the best-loved monsters from the past of the series, these stories are perfect for Doctor Who fans young and old.

Our 213th Main Range release is the gripping finale to our trilogy focusing on the Doctor's arch-enemy – The Two Masters! Geoffrey Beevers and Alex Macqueen's evil Time Lords take on the universe, with Sylvester McCoy's Seventh Doctor caught in between! Listen to the trailer below:

The future is dying. All over the universe, gaps are beginning to appear. From the space lanes terrorised by the rag-tag remnants of the once-mighty Rocket Men, to the empire of the Gorlans, stricken by a terrible civil war. Gaps in space/time, portents of the end of everything.

Only three beings might prevent it. The Doctor, a renegade Time Lord from Gallifrey. The Master, another renegade Time Lord from Gallifrey. And another Master, yet another renegade Time Lord from Gallifrey.

One Doctor. Two Masters. What could possibly go wrong?

Written by John Dorney and starring Sylvester McCoy, Geoffrey Beevers, Alex Macqueen, Lauren Crace, Russ Bain, Esther Hall, James Garnon and Neil Edmond, Doctor Who: The Two Masters is available to buy on CD and download now.

Peoples of the Universe, please attend carefully. The message that follows is vital for your listening pleasure. Doctor Who: The Two Masters contains plot-twists and surprises from the very beginning. Avoid spoilers and listen at once! You have been warned....

A longer than usual running time for this four part adventure means that behind-the-scenes interview could not be included on the disk - but all Big Finish customers can download them seperately from their accounts at no additional charge!
