Medicus

Why it’s on the list: First of Downie’s Gaius Petreius Ruso mysteries — a Roman army doctor posted to Britannia, detective fiction built on the daily texture of an imperial garrison town.

Where I saw it: In the reply thread to @moseskagan’s question, “What historical fiction should I read next? (Bonus points for something involving building or trade, rather than violence)” (April 13, 2025) — a crowd-sourced list Kyle recovered by hand and saved to his Apple Note “Books To Read”; the full set of replies lives on What historical fiction should I… (tweet). It was listed there as “Medicus by Ruth Downie”.
