The story sees the Doctor and Leela visit Derbyshire in 1979. In an area that has a legend about a great white worm that comes our out of the rocks and eats animals. And occasionally humans.
Quickly caught up in a manhunt, the time travellers soon find bigger things are going on here. For an old enemy of the Doctor's is also in the area. They are hunting the worm as well. And the stakes are suddenly much higher....
As with all the other stories in this run the two leads are great and some of their dialogue is absolutely superb. The recreation of the style of Doctor Who at the time is as well, thanks to good music and sound design. And there are some nice little touches to create the period which should bring a smile to the face of anyone who lived through the 1970's.
This story is a rather odd mix of styles, though, and never the out and out horror one that the cover and the description might imply. The first episode, after a great start, does rather get sidetracked with a long introduction for an eccentric supporting character that does come close to getting a bit silly.
Yet there are twists and turns galore here and the story will constantly surprise you as it goes along.
The old enemy [no spoilers but anyone not wanting to know should avoid looking at the cover of the box and the cast list on the back] is played by the original actor, and they do a superb job of returning to a part they first played decades before.
As mentioned this is the start of a longer story, and that means it ends on a big cliffhanger and you will need to hear the the next release in this run to find what happens next.
So this isn't quite perfect and not the best of this run so far but there's still a lot to like about it and it's well worth a listen.
The trailer for the aforementioned next story can be found on track on the cd right after the end of part two.
And fifteen minutes [approx] of interviews with cast and crew are on the tracks after that.
