St. Kilda's streets hang with fairy lights. Tea dances, tango competitions, lifesaving demonstrations, lantern shows, and picnics on the beach are all part of the town’s first Flower Parade. And who should be Queen of the Flowers but the Honourable Phryne Fisher? It seems that the lovely Phryne has nothing to do but buy dresses, drink cocktails, and dine in lavish restaurants. Unfortunately, disappearances during this joyous festival aren’t limited to the magic shows. One of Phryne’s flower maidens has simply vanished. And so, Phryne is off to investigate aided by Bert and Cec and her trusty little beretta. When her darling adopted daughter Ruth goes missing, Phryne is determined that nothing will stand in the way of her investigation.
