I couldn't put this book down. Our heroine, Kiera aka Lady Darby has been rusticating in her sister's home since her husband's death and scandal involving his activities. Greatly maligned and object of scorn by the rather catty gentry visiting her sister's home for a house party, she finds herself in a middle of a murder. The investigator, Sebastian Gage, appears to be a rakehell son of a competent investigator and Kiera is dubious of Sebastian's abilities. However, he proves that there is more than to him than his father's reputation. There are a lot of twists and turns. It was very enjoyable and I look forward to reading the next novel in the series.
