I am plotting a crime mystery novel. I have the story and gist in place. It should have the "whodunit" element. I want to use Third person multiple pov narrative(more than 6+ povs). I've seen it done (but not in mystery) by having the character name at the beginning of a chapter.
Now my dilemma, how do I get around keeping the killer/killers a suspense while using such an approach. Are there any other ways to incorporate the pov I want, without giving away the name of the character. It is okay if the reader knows its the killers pov (just not who he/she is).
Maybe by a clear depiction of the criminals dark opinion? Or by altogether avoiding character names before chapters, and letting the reader figure out who's pov it is(but I feel it would be confusing, with 6+ povs).
Any input, suggestions and experience with using 3rd person multiple povs is welcome.
