I loved this novel! The past of the new foreign secretary Sir Henry Cunningham is the basis for the three deaths that occur in the story. The first death is the murder of sixteen-year-old Amelia Hardcastle while at a ball celebrating the coronation of King George and the arrival of the Cunninghams. Amelia was thrown off of a balcony while wearing a beautiful amethyst colored dress and it was initially thought to be either a suicide or an accident. However, the position of the body doesn't show suicide. Her autopsy shows injuries to her head which happened before she fell.
Sir Henry dies in his sleep a few days later. Again, the position of his body shows he probably was killed and poison becomes the leading reason for his death. The powers that be would like these deaths to be swept under the rug but Curran will not let that happen. Then Lady Cunningham's maid is killed, further intensifying Curran's investigation.
There’s also a secondary plot that involves the search for some jewel thieves that will be fraught with personal danger for Robert Curran which is a given in the series. Curran always gets injured at least once in each book in the series. The personal relationship between Harriet and Curran has been developed over the course of 5 books and reaches new heights in Agony in Amethyst. I don't want to be a spoiler but the author gives us a very satisfactory finish for these characters.
The writing is superb as usual. You have to think hard about the evidence as it is presented and wonder how the clues come together. The perpetrators are not obvious until the end of the book, mainly because there are alot of villains to choose from. Through Curran we get to see a thorough police investigation. There are several intriguing twists to weigh in determining the whodunnit, which I was unable to figure out.
I am sad that the author has no plans to continue this series. She made this same statement after book number 3 but we are lucky to have received books 4 and 5. She did not say that we have seen the last of the Harriet and Curran characters though. Perhaps we will see them again in the future. The author has left that possibility open.
5 out of 5 stars.
