When is a talkative chair not a talkative chair?

When it's an alien shower curtain. Or a stumpy git in a pith helmet.

But, underwhelming as they are, the Vardans still plan an Invasion of Time by conquering pound-shop Gallifrey – a land of medicinal jelly beans, powerful ping pong balls and walnut-chomping dropouts.

Its denizens include Chancellor Borusa who's more put-upon than Tom Baker's beer mat and Castellan Kelner who's slimier than a newly-painted Myrka. And, of course, a prototype Romana who's qualified to wield a screwdriver but can't hack it in the university of life, even with a bumper pack of Giant Smarties at her side.

The Doctor shouts, K9 snarks and Leela shacks up with an innocent bystander, while the surprise Sontarans stomp about, searching in vain for a jellied eels stall.

But did Jim and Martin find the story an all-conquering triumph or was it just an unwelcome invasion of their time?

Listen to find out.

The lads also review the audiobooks of The Doomsday Weapon and The Edge of Destruction.
