That Night on Thistle Lane by Carla Neggers
Librarian Phoebe O’Dunn lives in the small New England town of Knight’s Bridge and is quite content with her orderly and practical life. Until she finds a hidden room in the attic of her library packed with beautifully made vintage dresses and Hollywood costume replicas. Inspired by her find she plans a vintage fashion show, but first lends two of the dresses to her sister and her best friend so they can attend a masquerade ball in Boston. Swept up by her discovery she also secretly uses a ticket to the ball herself and dresses like a princess in a gown which would have fit perfectly in the movie Titanic. At the ball she dances with a gorgeous stranger dressed as a swashbuckler. Will she ever see her dancing partner again? Does she want to? Who was he? And who created the dresses? Why was the sewing room hidden so well in the library attic?
While there is romance, like many of Neggers’ books this is romance suspense. There are two mysteries (which of course turn out to be intertwined) concerning the characters in the novel, neither of which is too mysterious nor threatening, but that is not the impression at first. This is the second in the series taking place in this small town and you know there will be quite a few more.
