I am not a writer but I wrote a fantasy novel as a way to relax. I am currently editing right now and I have learned a lot about grammar but I still have many questions. Sometimes I can find the answers via web searches on English/grammar sites, but this is one question for which I was unable to find an answer.
Most of the use cases would be along the lines of conversation where a persons title is used instead of their name.

- “I would be most grateful for your assistance on the matter, [C/c]onstable.”
- The [C/c]onstable nodded and sat down.
