From the write up for book 1.
Lily Bard is a loner. Fiercely protective of her independence, she concentrates on her karate skills and her work as the proprietor of a cleaning and errand-running service, and pays little attention to the town around her. When her landlord is murdered, though, she looks like the prime suspect. Uncovering the real killer may be the only way to prove her innocence, and Lily realizes that she must focus on the other residents of tiny Shakespeare. Her job gives her easy access to people's private lives, and she begins to snoop, finding plenty of skeleton-filled closets, and exposing herself to the unwanted attentions of a murderer.
