August 1903. Emma and her husband Derrick are among the men in white tie and tails and the women wearing white gowns from the House of Worth at Tessie Oelrichs’s Bal Blanc, or White Ball, at Rosecliff, her grand cottage on Bellevue Avenue.

There to cover the event of the season is young Ethan Merriman, society reporter for the Newport Messenger, the newspaper owned by Emma and Derrick. It's an utterly charming affair until a stranger intrudes flaunting a green-striped necktie and matching vest in defiance of their hostess's theme. But his fashion crime is a mere misdemeanor compared to his intention to blackmail Mrs. Oelrichs by producing a compromising document supposedly signed by Tessie over a decade ago. Insisting it's a forgery but terrified of scandal, she agrees to his terms, but the blackmailer will not live to see payday. His body is found face down in a fountain before the party's end. Beside him stands a very wet Ethan, who was seen being confronted by the man earlier in the evening. Coming to the aid of their luckless cub reporter, Emma and Derrick must sort through the white lies and blackened reputations to discover the identity of the true killer.
