Very few authors these days use an omniscient point of view, so I find it quite jarring when an author writing in third person restricted suddenly tacks an omniscient sentence onto the end of a scene or chapter as a cheap way of creating suspense.
When you’re writing in third person restricted, the reader only knows what the character knows. That said, it’s a foul to have the main character step out of a house, get in his car and drive off, and then follow that with Bob didn’t see the man in the woods across from his house taking pictures.
If Bob didn’t see it, it can’t be in the book.
I’m reading a black ops book by a name author who writes a lot of these novels, and he’s been cheating on his point of view with these kinds of sloppy POV deviations throughout the book. I’m used to them, but I don’t like them. And I wonder why the line editor at his publishing house let them get into the published copy.
