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 of the ends justifying 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.
It's a well-written book, by its Australian author. I'm actually only half-way through, but it's enjoyable. You like the character of Phrynne and her maid, Dot, and the 1920s milieu is well drawn.
However, as is my way when reading a mystery, I have peaked at the end, and while it is a satisfactory ending in many ways (as two plots are entwined in one), one of the two is illogical, although I can't explain why without giving the plot away.
I shall put a spoiler and then explain the problem.
SPOILER
The jewel thieves go on cruise after cruise, robbing people...but someone on board knows that they are the jewel thieves, and forces them to hand over the jewel, which they then sell and give the proceeds to a needy person (done dirt by the person who originally owned the jewel.) It's uncertain, to me, anyway, whether the 10% handling fee referred to is given to the thieves, for their trouble, or taken by the person who knows about them. Presumably the 10% fee goes to the thieves...why else would they continue to steal jewels on the cruises when they weren't allowed to keep the proceeds????
