Sorry for the multiple posts, my vision has a hard time reading black on white. Your punctuation is excellent, and not overused, making for a nice read , my eye’s ride the waves easily.
One thing, a pet peeve. I love that you use the sparingly. But your line, “Aye, sir,” came the reply, might be changed to his. You have already identified who the is in your first sentence i.e. male, so it might be relevant, to identify or not to identify. Or, did you mean to write, Harking looked at the RO, shaking his head ?, that would clear it up too.
Harking looked at the RO, shaking his head wouldn’t work, because that indicates it was Harking who shook his head. It wasn’t. It was the RO communicating, nonverbally, that there was nothing to report.
I think this may be the first time I’ve ever seen someone get pedantic over the use of the word ‘the’. In this case, it was not a grammatical mis-step, but rather a specific stylistic choice (and one, I might add, that sees fairly common and regular use in literature).
