The latest Lost Stories release from Big Finish gives us an end to the current Colin Baker trilogy that we’ve been enjoying.

The First Sontarans promises to be an unforgettable story regarding Sontar’s potato resembling warmongers and their beginnings.

Due to the nature of the secrets held within the story, Producer David Richardson has a favour to ask of all the listeners who purchase this adventure:

“You’ll discover the secret of the Sontarans – and it’s a secret so significant that I hope listeners will help us keep it under wraps until everyone gets a chance to hear it…”

Here’s a little preview for you:

“1872. After finding a strange signalling device on the moon, the Doctor and Peri travel to the depths of the English countryside to track down the source of its transmissions. But they’re not the first aliens to arrive on the scene.

Old enemies of the Doctor are drawing their battle lines in the forest and the local humans will be lucky to escape the conflagration unscathed.

For hidden within this village is a deadly secret – a secret that could destroy the entire Sontaran race… and reveal the terrible mystery of their creation.”

The First Sontarans stars Colin Baker, Nicola Bryant and Dan Starkey and can be purchased for £14.99 on CD or £12.99 via download from www.bigfinish.com.
