Murder by the Book / Beyond the page bookstore mystery, Book 1.
(Book)

Addie Greyborne loved working with rare books at the Boston Public Library. She even got to play detective, tracking down clues about mysterious old volumes. But she didn't expect her sleuthing skills to come in so handy in a little seaside town. Addie left some painful memories behind in the big city, including the unsolved murder of her fiance and her father's fatal car accident. After an unexpected inheritance from a great aunt, she's moved to a small New England town founded by her ancestors back in colonial times, and living in spacious Greyborne Manor, on a hilltop overlooking the harbor. Best of all, her aunt also left her countless first editions and other treasures providing an inventory to start her own store. But there's trouble from day one, and not just from the grumpy woman who runs the bakery next door. A car nearly runs Addie down. Someone steals a copy of Alice in Wonderland. Then, Addie's friend, Serena, who owns a nearby tea shop, is arrested for killing another local merchant. The police seem pretty sure they've got the story in hand, but Addie's not going to let them close the book on this case without a fight.
