Penthouse, Pools, & Poison

This story is set at a Florida upscale resort where Millie Wentworth is the assistant general manager and discovers one of her guests dead in his penthouse suite. She has little faith in local law enforcement’s ability to solve the crime, so she takes it on herself with the help of her grandmother, Lulu, and Lulu’s dog, a Welsh corgi named Spud, and her friends.

There are lots of suspects loaded with motives. There are more stories in this series as well.
