The Marquess of Gorsewall Manor by Adella J. Harris

After being caught up in a raid on a molly house, Thomas Brook escapes on his way to the pillory. Collapsing from exhaustion on the moors of Yorkshire, he's rescued by the handsome Lord Elmsby and taken to Gorsewall Manor. As he recovers, Lord Elmsby offers him a position cataloging the library. It would be an ideal situation, isolated, with a handsome, solitary lord and servants who don't ask many questions, except for the strange sounds in the corners of the library and the feeling he's being watched. And then a body is found on the moors, a body that could be the long missing fiancee of Lord Elmsby, and Thomas must find out the truth of what happened at Gorsewall Manor. A gay - m/m Regency romance, 82,000 words, print version 315 pages
