When Priscilla runs into long-time friend Kitty Merrick, mystery starts to unfold. Kitty has just arrived on Martha’s Vineyard to check on her Aunt Katherine, who has stopped responding to her attempts at communication. Priscilla accompanies Kitty to the town hall, where they learn that Katherine has died. But Kitty isn’t convinced that’s truly the case, and she and Priscilla set out to learn what has actually become of her aunt.
Priscilla suspects there is more to a mysterious stranger than he is letting on when he starts asking questions about the missing Katherine. Meanwhile, Miss Caroline Waterman, Katherine’s best friend and former-socialite-turned-recluse, has announced she is selling acres of prime real estate— and a valuable private museum collection she’s gathered over the years. Will Priscilla be able to uncover the truth behind all these secrets and bring about the reunion—or the closure—her friend needs?
