I'm nearly finished with
Bookplate Special, the third (of four) in Lorna Barrett's "Booktown" series, featuring mystery bookshop owner Tricia Miles, set in the town of Stoneham, NH ... which was dying until a local magul had the idea of turning the unused downtown stores into bookstores of different genres (mystery, history, food, etc.).
Tricia and her sister Angelica come from a wealthy family, and have lots of loot from previous marriages, but at least Angelica runs two businesses (cookbook store and separate restaurant), as well as having a book under contract. Tricia seems arrogant about having gone to Dartmouth, as well as deciding that the local sheriff is nasty to her because she's "jealous" of Tricia's looks. In this book, Sheriff Wendy Adams has turned over the homicide case (third body Tricia has found in the same small town in barely a year!) to a male staff member instead, basically washing her hands of the bookseller. Tricia keeps meddling at every turn, and then feels aggrieved that Captain Baker finally blows up! She's really become incredibly self-absorbed at this point; she may be (relatively) good looking and wealthy, but her spoiled background ("After all the money my father spent on Ivy League educations, he'd be horrified to see me now!" - she was washing dishes at her sister's place for a few minutes - once!) seems like rather a turn-off to me!
