Death of a Dishonorable Gentleman is the first in the Lady Montfort series by Tessa Arlen. Per SYKM, it was a finalist for the 2015 Agatha Award for Best Historical Novel. It has dropped to $1.99 at Kindle and Kobo US. I haven’t read any books in this series, but have read and enjoyed both of Arlen’s later Poppy Redfern books.
