The nice men at P&O are worried. A succession of jewelry thefts from the first-class passengers is hardly the best advertisement for their cruises. Especially when it is likely that a passenger is the thief. Phryne Fisher, with her Lulu bob, green eyes, cupid's bow lips, and sense that the ends justify the means, is just the person to mingle seamlessly with the upper classes and take on a case of theft on the high seas - or at least on the S.S. Hinemoa, on a luxury cruise to New Zealand. She is carrying the Great Queen of Sapphires, the Maharani, as bait.
Phryne Fisher is called in to investigate the mysterious death of a famous author and illustrator of fairy stories. Seductive flapper and brave gal about town, Phryne Fisher, is called in to investigate the mysterious death of a famous author and illustrator. Working undercover in a women's magazine, Phryne's personal life is thrown into chaos when she is summoned by her lover's family.
Phryne Fisher is on holiday. She means to take the train to Sydney (where the harbour bridge is being built), go to a few cricket matches, dine with the Chancellor of the university and perhaps go to the Arts Ball with that celebrated young modernist, Chas Nutall. She has the costume of a lifetime and she's not afraid to use it. When she arrives there, however, her maid Dot finds that her extremely respectable married sister Joan has vanished, leaving her small children to the neglectful care of a resentful husband.
The redoubtable Phryne Fisher is holidaying at Cave House, a Gothic mansion in the heart of Australia's Victorian mountain country. But the peaceful surroundings mask danger. Her host is receiving death threats, lethal traps are set without explanation, and the parlour maid is found strangled to death. What with the reappearance of mysterious funerary urns, a pair of young lovers, an extremely eccentric swagman, an angry outcast heir, and the luscious Lin Chung, Phryne's attention has definitely been caught.
Running late to a gala performance of Gilbert and Sullivan's Ruddigore, Phryne Fisher meets some thugs in dark alley and handles them convincingly before they can ruin her silver dress. She then finds that she has rescued the handsome Lin Chung, and his grandmother, who briefly mistake her for a deity. Denying divinity but accepting cognac, she later continues safely to the theatre where her night is again interrupted by a bizarre death onstage. What links can Phryne find between the ridiculously entertaining plot of Ruddigore, or the actors treading the boards of His Majesty's Theatre?
