Branching character views are pretty much stapple of any novel. Multiple parallel plot threads are actually part of a definition of novel, at least in Poland.The game will always shadow the books, no matter how much it tries to stand on its own -- certain things that are outside the conventions of gaming will follow in suit of this -- such as branching character views. I believe the Witcher books (only read the two English ones) have such scenes, but unfortunately I cannot recall.
The thing is that game is a different medium with it's own rules, strengths and limitations. If ou actually control the protagonist, you should, generally be limited to protagonist's knowledge (with a few permissible exceptions if they can't really affect your behaviour) and you should be limited to controlling this protagonist and at most his immediate allies in the same area if it's required by gameplay (party based cRPGs). Stennis or Henselt when they duke it out don't really fit such criteria.
