WPC Ann Kelso joins the Fourth Doctor and K9 in The Syndicate Master Plan - and we can't wait to see what happens! The Fourth Doctor's new companion is set to make a big impact...

The Fourth Doctor Adventures – Series 8: The Syndicate Master Plan Volume 1 is out now.

When the Doctor decides to trace an anomalous energy signature on twentieth century Earth, he stumbles into an assassination attempt.

Gangland thugs are trying to murder a seemingly innocent shopkeeper, and it’s only the intervention of the Doctor and Ann Kelso – a WPC who happens to be on the scene – that prevents a tragedy.

But why do the gangsters want the shopkeeper dead? And what does this have to do with alien technology?

The first stages of a grand conspiracy are about to be revealed. And finding the answers will take Ann Kelso on a journey like no other.

Ann Kelso (played by Jane Slavin) is a police officer in 1978, who during the course of the strangest investigation of her career, happens upon an old battered Police Box and its eccentric occupant…

“Part of the excitement of Doctor Who is the secrecy surrounding everything,’’ says Jane. “For about a year now I've wanted to tweet, ‘K9 called me Mistress!’ We had to be so secretive I didn't know what I was doing myself until about two weeks before we recorded the first episode.

“Ann is everything you would want from a companion, in real life, in a TARDIS, in a crisis – she's brave and funny and absolutely up for adventure, regardless of risk. Justice is way more important than self-preservation. Let's just drop everything and zip off to a different planet without so much as a second look at Earth! She's either brilliantly brave or mad as a bat!”
