It’s 1927 in Galveston, Texas—the “Sin City of the Southwest.” Jasmine (“Jazz”) Cross is an ambitious 21-year-old society reporter for the Galveston Gazette who tries to be taken seriously by the good-old-boy staff, but the editors only assign her fluffy puff pieces, like writing profiles of bathing beauties. The last thing Jazz wants to do is compare make-up tips with ditzy dames competing in the Miss Universe contest, known as the “International Pageant of Pulchritude and Bathing Girl Revue.”
She’d rather help solve the murders of young prostitutes who turn up all over town, but city officials insist on burying the stories during Splash Day festivities. After Jazz gets to know the bathing beauties, she realizes there’s a lot more to them than just pretty faces and figures. Jazz becomes suspicious when she finds out the contest is also sponsored by the Maceos, aspiring Beach Gang leaders and co-owners of the Hollywood Dinner Club, where the girls will perform before the parade and pageant.
Worse, her half-brother Sammy Cook, owner of the Oasis, a speakeasy on a rival gang’s turf, asks her to call in a favor from handsome Prohibition Agent James Burton—an impossible request that could compromise both of their jobs and budding romance. While Agent Burton gives her the cold shoulder, she fends off advances from Colin Ferris, an attractive but dangerous gangster who threatens Sammy as well as Burton. In the end, she must risk it all to save her friends from a violent killer hell-bent on revenge. Inspired by actual events. (Sequel to Flappers, Flasks and Foul Play)
