The best cliffhanger ever?

It's been one of the most elusive of the Big Finish plays for me to track down, but I managed to finally get a copy of 'Doctor Who and the Pirates' using the 'used & new' link from Amazon.
I've just finished listening to disc one and, whilst I do not wish to give away any details, the cliffhanger at the end of episode 2 just has to be one of the best Doctor Who episode endings ever written.
Big Finish have been producing original Doctor Who for quite a few years now and have produced some outstanding plays but if you've never listened to this play, I can certainly recommend this one.
