Diamonds, Dunes, & Death - Port Sunset Mysteries

I'm Millie Wentworth and I never thought I'd be involved in another murder, but here I am smack dab in the middle of a crime wave at the swanky resort where I'm Assistant General Manager. It started with a major diamond heist and ended with a dead body on the beach. When one of my grandmother Lulu's group of fun-loving septuagenarian friends is a prime suspect it's time for Lulu's Crew, Spud the corgi, and me, to get sleuthing and uncover the real criminals.
And because dodging mobsters, international jewel thieves, and solving crimes isn't stressful enough, my hypercritical parents are in town too. My mother doesn't approve of Lulu and me in the best of times, and these are decidedly not the best of times. Plus she's already planning my imaginary wedding to my kinda-sorta boyfriend Scott. All I need to do is catch a murderer plus a jewel thief and survive my parents' visit.
No problem, right?
