Told from viewpoint of multiple characters over a 6 year span of time in late 1890s. A wealthy prominent man, Bay, has just been murdered and his wife, Annabelle, gone missing from a costumed ball they were hosting at their newly built mansion on the Hudson in NY. Bay's sister Janie and an investigative reporter search for answers. We see the background story of Bay and Annabelle who met 6 years earlier in England and learn of their childhoods as well. There are some surprises along the way and the coroner's inquiry. Both Annabelle (is she Georgie or is she really Annabelle??) and Bay have some enemies in the background despite their storied lifestyle so you are kept guessing until the end as to what happened. A little slow moving at times and lots of Shakespeare references which I didn't always get, but well written with a good story and good ending.
