I don't hate any Missy adventure, but this is a weak close to an otherwise excellent boxset. We know from the beginning that neither Missy nor the Monk will fall to the Ogrons. While other audios with similarly predictable outcomes manage to build tension, this one does not.

Perhaps the Ogrons do not work in audio. They are the opposite of the Daleks, who are made scarier in audio because their disembodied voice is scarier than the same voice embodied in a trash can. The Ogrons have a stupid voice, but the visual of a great, hulking monster-mercenary gives them weight. Here we don't have the visuals. We just have line-reads that take forever.
