Banishment from New York aboard a magnificent luxury liner should have been the wealthy socialite's ideal escape from disgrace, but everything changes when a moonlit stroll leaves Lillian the only witness to a shocking murder.

Could a hot tempered American millionaire be behind the killing? Or perhaps a certain handsome, blind pianist who guards a secret? And what does the victim's bitter wife have to hide?

Determined to answer questions no one else is asking, Lillian enlists the aid of her twin brother Felix - as often as she can drag him away from the card tables. The Crawford siblings' idyllic voyage becomes a fight for their lives, as they race to uncover the identity of a killer...before they become the next victims.
