It Takes Two to Mango by Carrie Doyle

It's all fun in the sun until someone turns up dead
After Plum Lockhart's job as a travel magazine editor is eliminated in corporate cuts, she decides she's sick of cold winters in NYC and fruitless swiping on dating apps—what she needs is a dramatic change of scenery. On a whim, she accepts a job as a villa broker and moves to a beautiful Caribbean island.
However, paradise isn't as perfect as it seems: the slow pace of island life, the language barrier, and a cutthroat office rival make Plum question leaving her old life behind. But when a client is found dead in the jacuzzi of Casa Mango—a property Plum manages—she knows she's really in a jam. With a killer loose on the island Plum will have to deal with a stonewalling police chief, a string of baffling clues, and a handsome Director of Security to solve this deadly case!
