Curiosity Killed the Cat Sitter by Blaize Clements
Really enjoyed this first-in-a-series about Dixie Hemingway. Once a Sheriff's Deputy in Florida, she's left the Department due to stress resulting from the deaths of her husband and daughter in a car accident. She now makes her living pet-sitting for people in her affluent community of Siesta Key.
When she finds a dead body in the home of one of her clients, it leads her to discover a lot of things about her fellow townspeople (murder, blackmail, child abuse) that she wishes she hadn't. Then she finds the body of that client in the woods. When other clients start avoiding her because of her connection to the deaths, she decides to investigate on her own.
Two things: 1 - the title is totally misleading: Dixie does not get killed, and
2 - hopefully, the second book in the series will tie up a lot of the loose ends that are left at the end of this one.
