Search - Sick of Shadows (Edwardian Murder Mysteries, Bk 3)

If you missed the first novel in this series, get it right away. Snobbery with Violence introduced the Edwardian heroine Lady Rose Summer. Her second appearance is, if anything, even wittier and more amusing than the debut.
Captain Harry Cathcart and Lady Rose Summer have entered into an engagement of convenience-convenient for Rose, who wants to avoid being sent to India with all the other failed debutantes. Despite her considerable good looks, Rose's sharp intellect and radical ideas have served to repel her would be suitors.
Unfortunately, even a pretend engagement cannot save Rose from trouble. Bored with endless parties, teas, and balls, she befriends Dolly Tremaine, a beautiful young girl newly arrived from the country and overwhelmed by the demands of the Season. Rose is delighted to have a protégée but their friendship is cut tragically short when Dolly is found floating in a river. Harry is summoned immediately to help solve the mystery of Dolly's death, and to keep Rose from being the murderer's next victim.
