Phryne Fisher is back - as smart and sassy as ever.
Phryne Fisher, her sister Beth and her faithful maid, Dot, decide that Luna Park is the place for an afternoon of fun and excitement with Phryne's two daughters, Ruth and Jane. But in the dusty dark Ghost Train, amidst the squeals of horror and delight, a mummified bullet-studded corpse falls to the ground in front of them. Phryne Fisher's pleasure trip has definitely become business.
Digging to the bottom of this longstanding mystery takes her to the country town of Castlemaine where it soon becomes obvious that someone is trying to muzzle her investigations. With unknown threatening assailants on her path, Phryne seems headed for more trouble than usual.
Meanwhile, Phryne's lover Lin Chung has his own mystery to solve. Feuding families and lost gold fill his mind until he learns that Phryne herself has become missing treasure.
