Lots of great things about this disarmingly simple story, and great performances throughout. I loved the Dalek cameo, and bringing back the Nimon was a wonderful surprise.
Jim Mortimore’s music (available on his Bandcamp page) really does a good job of building the tension and carrying the atmosphere. The main players McGann, Fisher and Stephen Parring as Sebastian Grayle are all brilliant.
I think the sign of a good audio story is when talking/writing about it makes you want to listen to it again. It’s on my to-do list for tomorrow!
