I highly recommend this book. I've gotten into reading lots of historical fiction mysteries from many eras of British history (Roman, Elizabethan, Georgian, Victorian, Edwardian) but this is a slightly different animal. Written as if it's a recounting of a crime in Scotland in the 1860s, complete with explanations, transcripts, various experts, you almost feel like it must have been an actual event. It isn't a thriller, it's a slow simmering work of intrigue and social commentary. For a while, I thought I was reading Peter May's Black House work because it's very similar. But this work is a reader's delight. I liked it.
