We now come to The Last Adventure, probably the biggest and most anticipated Sixth Doctor release Big Finish has ever done, the Sixth Doctor’s regeneration is one of the most infamous in the show’s history, Colin Baker, still reeling from having been fired over the phone was then approached to film a regeneration scene, a regeneration that would take place in the opening scene of the new season. Angrily and rightly he told them where to stick the offer. Now a smart producer would just forgo the regeneration and jump straight into the Seventh Doctor era leaving Six’s fate to the imagination, but instead we got Sylvester McCoy in a wig, McCoy who’s about a foot shorter and a lot slimmer than Colin Baker!

The actual cause of death of the Sixth Doctor wasn’t properly explained as the episode opened with him lying on the floor before changing. Over the years there’s been numerous attempts to explain what happened to varying degrees of success, some silly like banging his head on the console, others surreal like being murdered in his own mind by the unborn Seventh Doctor. But eventually Big Finish decided to produce The Last Adventure, the most definitive version of the Sixth Doctor’s death you’re ever likely to come across. Much like Trial of a Time Lord, this is actually four separate stories, but they can also be listened in an omnibus format from the bonus features as a single four hour story. And from the Valeyard’s perspective, it basically is a single four hour story as it revolves around his grand scheme to kill the Doctor which is carried out over various points in the Sixth Doctor’s life with different companions, culminating in the Sixth Doctor’s final adventure.

It opens with The End of the Line where the Sixth Doctor and Constance Clarke in her first appearance in Big Finish find themselves lost in a fog where they encounter multiple versions of the same train with the same passengers. It's a great showcase of the alternate realities and how bringing them together can be catastrophic, I don't enjoy this one as much as most fans do, I appreciate how they worked around involving the Anthony Ainley Master but it was done in such a contrived manner. But I still had fun listening to this, Miranda Raison effortlessly nails having a strong rapport with the Doctor helped in part by their real life friendship and the surprise appearance of the Valeyard was the highlight of the story for me
