Mystery of Ruby's Roulette - Rose Donovan - Bog

A secret mission to Lisbon.
A murder at the casino.
And a killer gambling on escape.
New Year's Eve, 1935.
The clink of champagne flutes mingles with the rattle of the roulette ball. Fina's on a winning streak. But just as she's about to celebrate, someone gasps, chokes, and slides to the floor.
The Portuguese police treat it as a crime passionel, but Ruby and Fina have other ideas. Could the murder be linked to the high-level jewel-smuggling operation they've been asked to investigate? Working undercover, they scope out the other guests: a handsome airman, an icy princess, a genial mathematician, a suave croupier, and a Brazilian diva with flashy frocks and a personality to match. They all have something to hide - but the truth turns out to be far stranger than Fina could ever have dreamed.
Join Ruby, Fina, Pixley, and Gayatri as they battle with profiteers, saboteurs, assassins, and a ghostly apparition on their twistiest and most captivating adventure yet!
