Social Graces — Wendy Soliman

When a marquess's affair with a leading actress ends in murder it threatens to bring the integrity of the entire British aristocracy into disrepute. Lord Chichester persuades Jake Morton, the Earl of Torbay, to clear his name. Sophia Larson, the dead actress's sister, is equally determined to prove the marquess's guilt.
Thrown together with Otto Milton, an aspiring barrister and one of Jake's trusted vigilantes, they delve into the murky world of London theatre land and unearth a number of alternative suspects, all of whom had reasons to want Connie Saville dead. Sophia, is out of her depth mixing in such elevated company and fights her inappropriate feelings for Otto, convinced that nothing can come of them.
Olivia Morton, Jake's countess, also befriends Sophia but is unable to stop her from rashly placing herself in danger in an effort to reveal the identity of the killer. Will Otto be in time to save Sophia from her own impetuosity…
