A Fatal Waltz: Tasha Alexander

This was the 3rd of the Lady Ashton series. In this one she is engaged to Colin, but is introduced to a past love of his while at a gathering at a politician's house. The Politician is murdered during a hunting accident while all are gathered at his home. The suspect is Ivy's, Emily's best friend, husband. At the party the politician and the husband had a spectacular falling out. While the husband, Brandon, is in prison he requests Emily uncover the truth. Her discoveries lead her to Vienna where she is stalked by a murderer, though not the one she wants, and meets with other murderers. She discovers that Colin is still in love with his past girlfriend and feels both relief and sorrow when she is eventually "silenced". Emily is surprised to learn the murderess was actually closer to home than she originally thought. The wife of the murdered man was the culprit. She found out he was responsible for her brother's death, and he was the last of her family left when she was an orphaned girl.
