This is the first time I've come across such a phrase (in a novel) and I
couldn't find an explanation through an internet search.

question
meaning phrases
What does the phrase "そうくるんですか" mean?
Let's consider the following situation that Alice and Bob play Japanese chess.
Alice expected what Bob do next, but Bob's next move was beyond her
expectations.Then, maybe Alice said そうくるんですか to Bob.  
  
そうくるか/そうくるんですか/そうきたか are used when something unexpected happened to narrator.
Also, そうこなくっちゃ means that’s what I wanted to hear.

answer
In this case a direct parallel English expression comes to mind:

> "So it has come to that"
>
> そう(that)くる(come to)んです[explanatory]か

But as other users have pointed out, you should provide better context or no
one will be able to give you a satisfying answer.
