I can understand people's wariness about Big Finish re inventing or re interpreting classic Sci fi like Dr Who or Blake's 7, but their Star Cops series are excellent and seamlessly carry on where the TV show left off. Six episodes comprises the second BF series mostly set on Mars.
2.1 The New World by Andrew Smith
Nathan, Devis and Kenzy arrive on Mars after a six-month journey from Earth. They’ve come to set up a Star Cop base, but Mars is a very different environment from the one they’re used to on the Moon. They have their work cut out to convince some colonists of the need for law enforcement. They have no powers, no guns, and few friends.
Nathan sees an opportunity to prove their worth when there are reports of water thefts and disorder at a colony near Olympus Mons. He and Kenzy are invited to investigate, unofficially. Then a body is discovered, and the Star Cops have to work fast to prevent tensions escalating into further violence.
2.2 The Shadow of This Red Rock by Una McCormack
Nathan and Kenzy find themselves marooned in the Martian desert with a prisoner whose friends will soon arrive to attempt a violent rescue. Help arrives in the form of a reclusive colonist. Soon they’re all being chased across the desert by the prisoner’s friends, who seem able to anticipate every effort to shake them off.
Meanwhile, Devis has his own troubles. An attempt to come to his friends’ rescue goes wrong, and he finds himself at the mercy of colonists who hold his life in their hands.
Matters will come to a head in a perilous stand-off on the four-mile-high cliffs of the Mariner Valley canyon.
2.3 Whatever Happened to Gary Rice? by Guy Adams
After the Star Cops receive a cryptic message about a man who may once have worked at a colony in the Argyre Basin, they make their way there to investigate. They find a co-operative community that thrives by growing an organic food source, which it sells to other colonies. But no-one seems to remember the man the Star Cops are looking for.
Nathan visits a neighbouring scientific research base, where nutritionist Dr Julienne Grainger has information that may resolve the mystery of the missing colonist.
As the Star Cops get closer to discovering the truth, there are those who are prepared to kill to keep it secret.
2.4 Bodies of Evidence by Andrew Smith
On the moon, shortly before Nathan, Kenzy and Devis leave for Mars, disaster strikes when the shuttle Ganymede crash lands on the lunar surface.
The tragedy becomes something more sinister when Priya finds dismembered bodies hidden in the shuttle. But attempts to investigate are obstructed by higher authorities on Earth.
Before Nathan departs for Mars, he instructs Priya and Paul to investigate the crash, in defiance of his superiors’ orders. If they don’t find the evidence they need, it could be the end of all their careers.
2.5 Human Kind by Helen Goldwyn
A scared medic, on the run from her colony, seeks the help of the Star Cops. She offers information about a crime, but she demands legal immunity, and guarantees for her safety before she’ll talk.
A visitor from Earth seems particularly determined to stop the Star Cops gaining a foothold on Mars and calls a meeting of colony leaders in an attempt to end their efforts once and for all.
When one of his officers is kidnapped, Nathan begins to wonder who he can trust on this planet.
2.6 The Highest Ground by Andrew Smith
The conspiracy is revealed, and its leader is desperate to silence the Star Cops.
An armed squad closes in on Nathan, his officers and their Martian allies, leading to a siege in the shadow of Olympus Mons, the highest mountain in the solar system. And a violent confrontation on its slopes.
It’s time for some to decide where their loyalties truly lie before it’s too late...
