Medicus: a novel of the Roman Empire, by Ruth Downie

I've been reading British history for a few years now, and in preparation for my upcoming trip to London, I thought it would be fun to read some fiction set during the period of the Roman Empire. The main character of Medicus is a doctor named Ruso attached to the Roman army stationed in Deva (modern-day Chester). He comes across a man abusing an enslaved British woman and on an impulse he decides to purchase her at a bargain rate due to her broken arm. He treats her arm and as she begins to heal, Ruso becomes aware of several dead slaves, at least one of them clearly murdered. As he is unwillingly drawn into the investigation, he experiences several accidents (or were they?), a predatory boss, skyrocketing debts, and other pressures. This is the first of nine books in this series focusing on Ruso and his slave Tilla. It's well-written with a nicely-paced plot that kept me turning the pages. I'm looking forward to the next one in the series.
