Alternate history with Romans. Our protagonist Aquilla has been summoned to Radea, his commanding officer.
"Yes, Aquilla." He glanced at me, then at a sheet of paper I recognised as my report into the death of an elderly citizen of Alexandria. "What does 'killed while obstructing the legion's business' mean, this time?"
"Cavalry ran him down, sir."
Contradictory orders had given the old man no clue which way to jump.
Radea got up and came round his desk. I stood too, and he slapped me in the chest with my report.
"I've had four 'obstructions of the legion's business' from you of late. Be clearer in future. And more careful."
"These frequent incidents involving civilians...are they to do with your suspicion that they're all spies?"
"Not all of them, sir. Just some."
Prevailing opinion in the Twelfth regarding those who gathered to watch us drill ran thus: old men were veterans, reliving their glory days; boys and youths had a soldier for a hero; women were on the hunt for a husband. The Twelfth's lack of imagination infuriated me; they got annoyed when I drove off their admirers. [And the rest were probably spies.] [I would move this paragraph down two lines. The impact of the next two lines is diminished because the reader has to go back and see what Radea means by "Not all the Incidents?" We have such short attention spans.]
"Not all [of] the incidents?"
"Not all of the civilians, sir."
He flung the report back onto his desk. "I want an explanation."
Very nice. I'm not crazy about "I want an explanation." It sounds like you want to give the reader an explanation, so you get a character to request one. From a commanding officer, I'd expect something more like "This is going to stop. Is that understood?" Of course, I don't have the full context.
