This is the hundred and seventeenth release from Big Finish in their range of full cast audio adventures starring classic Doctor Whos. It stars Peter Davison as Five. There are four episodes, roughly 25-30 minutes each, complete with original theme music between each, and cliff hanger endings. Two episodes per disc on 2 discs, and a short booklet with some pictures of the cast and production notes. There are some interviews with cast and crew at the end of each disc. This is the start of a trilogy of adventures called Key2Time, following up on the Fourth Doctor's adventures with that artefact, and Five's brushes with the Black Guardian.
Five finds himself separated from Peri and confronted by a mysterious girl. Soon he is whisked off on an adventure to find the Key to Time once again, though this time there is a bit of urgency about the job as the universe is about to come to an end. What follows is an interesting tale in which the origins of the Ice Warriors is explored for the first half, then an interesting little run around in the second half. It's an interesting story, if a bit weak at times. The inherent dignity of the Ice Warriors and their origins story carries most of it, the rest is standard running about getting into and out of scrapes.
An unpromising start to the trilogy, but manages to keep the interest. Actually, on reflection it's not that bad, it's just that compared to the previous few releases featuring Five (the Brewster trilogy) it feels a bit overshadowed and I was expecting a bit more.
Three stars overall.
