The artwork for the eighth series of the Fourth Doctor Adventures is out now.

The Fourth Doctor Adventures Series 8: The Syndicate Master Plan starts with The Sinestran Kill by Andrew Smith, in which aliens have become involved in the London crime scene in 1978. Frank Skinner (Mummy on the Orient Express, Callan) plays DCI Scott Neilson while Glynis Barber (Blake’s 7) is Kathy Blake.

New companion Ann Kelso takes a trip into history in The Enchantress of Numbers by Simon Barnard and Paul Morris, as she and the Doctor meet Ada Lovelace (Finty Williams), the daughter of Lord Byron and a Victorian computer pioneer. But what are the bird-masked strangers that are stalking the local village?

Ann’s first trip into space then takes her to the Planet of the Drashigs, where writer Phil Mulryne throws the Doctor, Ann and K9 into a theme park where different species of Drashigs are about to run wild. Fenella Woolgar (The Unicorn and the Wasp) plays Vanessa Seaborne.

The box set ends with The False Guardian, which leads into the Fourth Doctor Series Eight Volume 2’s first adventure Time’s Assassin. Both scripts written by Guy Adams, and guest starring John Shrapnel, Blake Ritson and Jon Culshaw.

In Fever Island by Jonathan Barnes the TARDIS lands on a misty, mysterious island where scientists are conducting strange experiments, and all may not be as it seems. Gethin Anthony (Game of Thrones) plays Jason Vane. The season ends with a four-part story, The Perfect Prisoners by John Dorney. Ann Kelso’s investigations are reaching their climax, and the Doctor will have to make one of the hardest decisions of his many lives....

The Fourth Doctor's new companion in The Syndicate Master Plan is set to make a huge impression on his life… Welcome Ann Kelso (played by Jane Slavin), 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… 

“We actually created the role for Jane,’ says David Richardson, producer. ‘Tom and Jane work brilliantly together - there’s an instant, indefinable chemistry between them every single time they record together at the studio. In real life, Jane just naturally feels like one of the Fourth Doctor’s companions - and so it was inevitable that eventually she would play one…”

“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!”
