The fact that Ryan Hudson, of all people, is intrinsic to this part of the story is a deft way for Nancy Drew to underline that the two are kind of alike. It’s satisfying that our heroine, currently with less than two days to live before the ghost of this same woman brutally murders her, still takes the time to stand up for her memory, highlighting the violence of what was done to her, and how that ultimately benefited the same town that now ignores her life. While there, Nancy ends up facing off with a mansplaining Horseshoe Bay tour guide, who is all too eager to declare that Odette was only memorable – and therefore only valuable – because she married a town founder. His second wife Agnes reportedly went mad and was imprisoned in the basement, and some memory of her lingers there still, a terrifying imprint that haunts the dank room where she scraped nonsensical messages on the walls. To prove it, Nancy and Bess head to the historical cottage where Captain Marvin used to live, where they discover that Odette wasn’t the only woman whose life he stole. In truth, she was murdered and her death covered up, all so that a greedy group of men could steal her fortune.
The sea shanty the group uncovered revealed her true fate, and it didn’t involve dying tragically of consumption. We already know that she was once Odette Lamar, a rich French heiress who also happened to be a brilliant businesswoman in her own right when Douglas Marvin brought her to America.
