Violet and Sephora are in a better place in their relationship, though Violet continues to keep her role as Miss Hermione secret, knowing it would hurt Sephora if she discovered she was writing to her older, staid and colourless sister (Sephora's assessment, not mine).
When Miss Hermione receives a letter about a daughter who has joined an odd group, Violet decides this is the situation she'll investigate, particularly as the daughter is Sephora's friend Margaret.
Reluctantly taking Sephora with her to the group's gathering in a London park, Violet discovers that Margaret is involved with a cult called the Hermetic Order of the Children of Aed. Violet is not impressed by the look of the group, nor some of their ideas, but decides she's following the group to Nottingham, where she pretends to be contemplating joining. She meets the charismatic leader, known as Master, and his right hand Celestia, a woman who seems to convey a sense of menace, even while calmly pouring tea and welcoming people.
Despite agreeing with a few of the ideas, Violet also feels a distaste for some of the dictates of the cult, and thinks one might have led to a murder, of which Margaret stands accused, and which occurs shortly after her arrival. To Violet's surprise, during her digging into the cult's members and activities, she runs into Eli Marsh, the American detective she met during her first investigation, and whom she is attracted to.
This was a fun entry in this series. Violet remains a keen observer, and not easily duped by the trappings of the cult. She does make some mistakes, landing her in some trouble, but I knew Violet would eventually find the murderer (who wasn't hard to figure out). But what was particularly nice about this book was both sisters working together for a change, with Sephora proving she's not just a silly young person. I think there's hope for Sephora to grow some real sense. And, we also get a much better understanding of who Bunty is and it was great!
This was a fun story, and I look forward to another entry in this series.
