This is part of a series of reviews of Doctor Who in chronological timeline order.

Previous Story: Slipback

This story is a perfect example of Big Finish being able utilise the audio format to make really unique stories. This isn't a particularly experimental story by today's standards, but it was definitely a sign of things to come. Being Nicola Bryant's first performance as Peri for Big Finish and Colin's second they slip back (pun intended) into their roles quite naturally. The setting of an audio museum is perfect and I like how it technically continues on from Slipback. The story has a really compelling mystery and the idea of a monster that takes the form of a soundwave is terrifyingly done here (unlike a certain other sound-based villain).

Unfortunately this is where my compliments end. This story could easily have been a part shorter, there's a fair bit of padding and at one point the story was practically resolved only for something to happen again. It's impressive how much this story drags at times considering it's on the shorter end of Main Range releases. The cast, while they're all alright, sound really similar. There's a lot of characters and with them sounding so alike I found it hard to tell who was who except the Doctor and Peri. It also doesn't help that they're just forgettable characters in general.

Overall, I gave this story a 7 because I was impressed at how experimental it was for the time but in retrospect it's more of a 6.
