It was interesting to read this Seventh Doctor novel at the same time as the new Fourth Doctor audio The Renaissance Man, in that both involved Victorian-ish settings which turn out to be in some way representations of an inner space. This was apparently Messingham’s first book, but it’s a good combination of insect horror, worlds within worlds, and a new figure from the Doctor’s Gallifreyan past which casts a new light on his motivations. Ghost Light with mind projections, perhaps. One of the more memorable ones.
