usive gathering at Newport, Rhode Island's Beacon Rock mansion hits stormy seas in the summer of 1900 when reporter Emma Cross, a lesser Vanderbilt, discovers a drowned corpse in Alyssa Maxwell's tenth Gilded Newport Mystery...

As a reporter, Emma is used to covering Newport's social events. But this time she is appearing on the arm of her fiancé, Derrick Andrews, at a small but exclusive gathering of the New York Yacht Club at Beacon Rock, the Grecian-inspired summer "cottage" of Edwin and Elizabeth Morgan. The members--which include cousin and Yacht Club Commodore John Pierpoint Morgan and widow Lucy Carnegie, the first woman to be admitted to the Club--are there to discuss their strategy for the next America's Cup Challenge, to be held in New York Harbor the following summer.

But it's Emma who must come up with a strategy when she discovers a woman's body bobbing against one of the hulls of the boats moored at the base of Beacon Rock. After the woman is identified as the missing daughter of a yacht designer, the police--with the exception of Emma's friend Detective Jesse Whyte--hastily conclude she is a suicide, perhaps to quiet any scandal for the Morgans. But Emma suspects the woman was murdered and begins to sort through a who's who of sportsmen, boat crews, and the Newport elite in search of a stone-cold killer . . .
