Can't go wrong with Sarah Jane! And this one, unlike all the other CDs in the two Sarah Jane series, can be listened to as a stand-alone story, whereas you really need to follow the whole series (both of them) if you listen to any of the others. Not that you can't enjoy them on their own, they are all very good, especially the one entitled Snow Blind, but this story (Ghost Town) makes not much in the way of reference to the series as a whole so you don't need to know the complete background story to enjoy this one.
Great sound effects, as ever, with Big Finish, and a good and interesting story. Great cover art too!
