I'm currently reading Death on Windmill Way by Carrie Doyle. This book is the first in the Hampton's Murder Mystery series.
Antonia Bingham has finally escaped from an abusive husband in California and is starting over across the country. With a love of cooking and not much experience, Antonia bought the dilapidated old Windmill Inn in the Hamptons and poured all of her money, sparing no expense, into refurbishing it into a high end inn and restaurant. What she soon discovered, however, was not only that her money was running out, but all previous owners of the inn had died under suspicious circumstances. Was there some inn owner killing lunatic on the prowl? Not trusting the police, her abusive ex-husband was a cop, Antonia starts looking into the previous owner's death. Will her questions cause a killer to act once more or will Antonia be able to save her own skin and bring a murderer to justice?
