The Shadow of the Past is a story in Big Finish’s Companion Chronicles line, which features Caroline John as Dr. Elizabeth (Liz) Shaw and for this story, Lex Shrapnel as Marshall. An older, retired Liz goes to Unit Vault 75-73/Whitehall to look in to something from her time with the Doctor, she meets a young UNIT officer and tells him her tale.
A younger Liz is at UNIT when a spaceship crash is reported. She, the Doctor (the Third Doctor, as played by Jon Pertwee on the television series, Doctor Who) and UNIT troops head out to Kent to investigate. The Doctor is keen to try to rescue the pilot. Liz is a bit more cautious – insisting on contamination suits at least, and the Brigadier and company – well, this is a tale set early in the third Doctor’s time, so the Brigadier and the Doctor are still feeling each other out. Liz and the Doctor enter the spaceship – and Liz is overcome by the smell – the pilot is smeared all over the interior of the space ship.
Liz leaves and the Doctor rushes out and to his TARDIS at UNIT HQ. At UNIT, he reports another problem, a Mim invasion fleet is heading for Earth. The ship must have been a scout. Liz and the Doctor return to the control center set up by UNIT near the spaceship – only for the Doctor to remark by radio that Earth’s defenses are disabled and the Mim invasion can invade.
In the present, the older Liz explains to Marshall the properties of sponges. As long as you keep them in seawater – they can reassemble themselves. Cut them in half – and they will reunite. Whirl them into soup and they will reassemble. Even whirl two different sponges together into soup – and they will reassemble into the two original sponges – given enough time.
Picking up the story with young Liz, she and the Brigadier realise the person that invited the invasion fleet in – isn’t the Doctor. The entity reveals itself to be a huge purple beast – and attacks the UNIT soldiers and officers. The Brigadier orders Sgt. Robin to take Liz to UNIT HQ, find the Doctor, the real Doctor, and return. Liz protests but Robin insists she go with him.
At UNIT HQ, Liz realises she has a key to the TARDIS and enters. The Doctor is unconscious on the floor of the TARDIS. Liz realises the pilot of the ship wasn’t dead after all, but it attacked the Doctor, taking his shape – and as the recovering Doctor explains, it poisoned him as well. But he takes energy from the TARDIS to speed his recovery then uses the TARDIS to call the Time Lords. A man in a bowler hard and pinstripe suit appears, and Liz and Robin convince the Time Lord representative to help. The Time Lords return the Mim invasion fleet to the Mimsphere, but the representative says the Doctor and UNIT will have to deal with the Mim agent themselves.
The Doctor also explains that the Mim, as the name implies, are Mimics, shapeshifters, but they are also incredibly dangerous and violent. Liz realises that she had tried to shut down the nuclear weapons UNIT had but was dragged away by Robin – the Mim then finished her work, shutting down the weapons. But they can’t trigger a nuclear explosion in the middle of Kent.
The Doctor, Liz, and Robin return to the control center and talk to the Brigadier. They come up with a plan to get the Mim to return to it’s spaceship and to get a device inside.
As Liz explains to Marshall – that’s the spaceship here in the vault. She also mourns the death of young Robin and the other UNIT soldiers killed in the conflict. As she continues to talk to Marshall, pointing out how he reminds her of Robin – even looks like him, Marshall puts it together.
The rest is a spoiler, but you can probably guess where this one is going.
Still, I liked this Companion Chronicles story. It was a pleasure to listen to a story featuring Dr. Liz Shaw but its a bit bittersweet too, since she has subsequently passed away. That is one sad bit about the Companion Chronicles line, it can be hard listening to stories told by Doctor Who actors who have recently passed away. Shadow of the Past is a straight-forward Third Doctor story. A spaceship crashes, there’s an invasion, and I don’t think it’s a spoiler to say that UNIT and the Doctor defeat it. But it’s still a good story. The surprise at the end is a surprise, but it makes total sense once you know. Caroline John does a very good job telling the story and she plays well off Lex Shrapnel. Recommended.
