Series Five of The Fourth Doctor Adventures begins today with a rocking new story for the Doctor, Romana and K9.

Get into the Season 17 spirit with a brand new story starring Tom Baker, Lalla Ward and John Leeson. Doctor Who: Wave of Destruction finds the travellers with a mystery to solve in 1960's London – where a Pirate Radio station may hold the key to humanity's doom...

A modulated frequency wave cancellation signal isn’t something that the Doctor and Romana expect to detect in 1960s London. But then they don’t expect to find Professor Lanchester, the man who invented it, lying unconscious. Or MI5 investigating.

With the help of MI5 Agent Miller, Lanchester’s daughter Jill, and his nephew a pirate radio DJ called Mark, the Doctor, Romana and K-9 investigate. They soon discover that there is more at risk than they imagined, and an alien invasion is about to begin.

Can the Doctor identify and defeat the aliens in time? Will Romana manage to find a recombinant transducer before it’s too late? And how will K-9 cope with his new job?

Written by Justin Richards and starring Tom Baker, Lalla Ward, John Leeson, Karl Theobald, Phil Mulryne, Alix Wilton Regan and John Banks, Doctor Who – The Fourth Doctor Adventures: Wave of Destruction is available to buy and download today from the Big Finish website.
