5 Time Lords, 13 Companions, Can Anything Else Go Wrong?

The third and final instalment in the trilogy of 3D9C and 4D12C / Adventures through spacetime are balanced with the domestic lives of the usual cast of mismatched characters while they thwart intergalactic, cross-temporal, supernatural adversaries; everything ranging from killer space-squids to cults to parasitic toilet worms to invisible aliens and much more.
