It isn't something I considered much watching the TV ep but reading the book I keep thinking about the layout. The base is explicitly "very deep" in case there is a nuclear blast. The caves are beneath the base. Makes sense but not the impression I had #DoctorWho #CaveMonster
The police in the 1970's it turns out are particularly polite when contacting potential murder suspects... #DoctorWho #CaveMonster
All the Brigadier was missing was his own range of baseball caps #DoctorWho #CaveMonster
The first section of the book is set in the Silurian era (or whatever era it really is), as they prepare to enter the shelters. I've said this before but I would really love @bigfinish to make a series set in this era #DoctorWho #CaveMonster
