Evelyn is great, but I find The Marian Conspiracy
so-so outside of its fabulous introduction for her.
is indeed a good Cyberman story.
Everyone praises the bejeezus out of The Holy Terror
, but I have not heard it yet. My favorite standalone audios with Colin Baker are probably Davros
. The Condemned
and Arrangements for War
are excellent, too, but slot into complicated story arcs.
