I'm starting a new series by Ruth Downie (an author I've never read before), four novels of which I picked up in hardback at the library book sale for a dollar apiece. This first one is called Medicus and it's the first in the series (published in 2006) so I shouldn't have too much trouble with the others I bought, given there are some books missing between them. But as it's a mystery series, I assume each book will be more or less standalone as far as not needing to have read all of the previous ones.
In any case, the main character is a down-on-his luck doctor in ancient Roman times, off to his new duties in the faraway land of Brittania, where he'll apparently rescue a young slave and soon after get involved in a series of murders involving prostitutes. I enjoy ancient Roman historical fiction and I've taken to mysteries, so this should be a good mixture of the two.
