This is Big Finish release 154 - The Witch from the Well.
The eighth Doctor and Mary Shelley get caught up in a seventeenth century witch hunt which gets more complicated when the fast return switch on the Tardis separates them by 400 years.
This story didn't quite hit the heights of The Silver Turk but it is very good. There's a nice creepy element to the mystery of the titular witch. Personally I could have done with that mystery carrying on for a bit longer before the science fiction solution is revealed, but that is just my preference for spooky ghost stories.
There is only one problem with these eighth Doctor stories and it's the music. I assumed that Big Finish were using the appropriate theme music for each doctor and that this was the music from the TV movie. But as Paul from the TimeVault podcast pointed out on my previous post this is actually a remix.
When Channel 4 did their countdown of the 100 scariest moments they included the original Doctor Who theme music as an entry in its own right. The rock journalist Alexis Petridis described it then as a perfect piece of music, and I agree. That's not to say that I don't like the updated versions for the subsequent Doctors, I actually enjoy all of them apart from the movie version. If you want to listen to an interesting run through of all the theme tunes up to the tenth Doctor then check out Tom Dillahunt's Podcast Who and, in particular, his episodes 40, 41 and 42.
Anyway, this soft rock of version of the theme tune is the worst version out there, it really spoils the cliffhanger endings to the four episodes in this story. But let's look past that and give this Big Finish story 3.5 out of 5 Radiophonic workshops. Next up I'm jumping back in the Big Finish timeline and will be listening to Neverland.
