Is it okay to write a novel in past and present tense? I'm talking about changing tenses in different chapters. I've written a crime novel which is narrated in first person/past tense by the criminal and the detective who is trying to catch him. I thinking about changing the criminal's part so that it remains in first person, but in presence tense while the part of the detective remains in past tense. I wonder if this ok with agents and publishers.Is it ok to write a novel in the first person except the narrator doesn't speak?
Is it ok to write a novel in the first person except the narrator is dead?
Is it ok to write a novel in which the main character must solve his own murder?
How about an entire novel without the letter "e"
I'm sure you've intuited by now that my answer is you can do almost anything you want in a novel as long as it works.
And by works, I mean it tells a story that holds my attention and entices me to read on.
If writing in past and present tense for different characters serves the story, do it.
I don't pick up a manuscript and run down a checklist of items to try to reject it summarily.
I pick up a manuscript, open it to page one and start reading. If I get to page 50, I put it down and ask myself if I want to keep reading.
I don't say "wow, he shifted tenses, that's bad." I say "I don't give a rats asterisk about what happens next" OR I think "pick up that ms and get back to reading, I can't wait to find out what will happen next."
There are a lot of good novels written in two tenses for just the reasons you list in your question.
Don't worry about whether it's ok to do it. Worry about whether the story is served by it.
