Continuing a decent run of Who books, this is the Seventh Doctor story which introduces Jason Kane, husband of Bernice Summerfield. I knew a lot of Jason’s later continuity from Big Finish audios, but had somehow not absorbed that he was actually from 1996. Anyway, I was delighted with his introduction to the character, whose whirlwind romance with Benny comes against a background of mildly comical terror; meanwhile the Doctor is attempting to sort out a complex conflict between three competing alien races, and Roz and Chris have a subordinate but still entertaining plot line.
We agreed exactly on this one. I also agree that ranking them was easy.
