This is one of my favorites in the series so far, which is odd because I really don't like circuses all that much. I sorta cringe at the thought of books and art with that setting, in fact.
In this book, Phryne is approached by a lover to investigate why all kinds of misfortune is occurring at Farrell's traveling circus. She goes undercover, learns trick riding, and of course, saves the day. As she is undercover, she has to rely on her inner resources rather than her friends, staff, or money. All in all, a satisfying and fun read.
