"Why did they make the carpet of this hotel’s corridors so rough that you can’t haul a body along it? Actually, I think I may just have answered my own question." — Bernice Summerfield.
Finally Paul Cornell, who is the architect of what is most great about the Virgin "New Adventures" Doctor Who novels, gets a turn... and he plunks us right smack into the center of the "Virgin-verse". We get the grim, Machiavellian Seventh Doctor, the angry, post-Dalek Wars Ace and Cornell's companion invention, Dr. Bernice "Benny" Summerfield.
If you haven't read the New Adventures, trust me, this is a very good thing.
Then, he traps this dream team in a hotel in Kent where a sinister plot is being hatched by manipulating, I kid you not, a physics sales demonstration, a New Age convention and a gathering of cross-stitch enthusiasts. This is all a lot of fun... for about 2 episodes. After that, there's a lot of running and screaming and blowing stuff up. Not in a good way.
It feels like a story that was an explosion of creativity that resolved in shrapnel instead of fireworks. The production values are a little odd with Big Finish falling back to some of their old issues with being unable to delineate certain characters from others and difficulties in visualizing the stage in which the characters are playing.
And by the end, you probably won't really care.
