A Stranger in Mayfair by Charles Finch

Although I hadn't gotten the exact details right, I knew the linchpin on which this mystery turns early in the book. This book seems as much concerned about how Lenox manages the conflicting pressures of Parliament and detecting as the detective work itself. I found the characters more tedious in this outing--especially because Lenox and Lady Jane (his new wife) are utterly unwilling to say anything meaningful to each other the whole book.
