Bookshop owner and maid of honor Addie Greyborne vows to catch the killer who crashed her best friend’s wedding . . .
 
It promises to be Greyborne Harbor’s wedding of the year. The impending nuptials of Serena Chandler and Zach Ludlow will take place aboard his family’s luxurious super-yacht, currently moored in the harbor and the talk of the town. But on the day of the wedding, a man’s body washes up on the beach with no ID, only a torn page from a book in his pocket. As owner of Beyond the Page Books and Curios, bibliophile Addie is called in to identify the book, but she cannot.
 
The morning following the extravagant ceremony, a second body washes ashore and Addie has a sinking feeling that the two deaths are connected. While the guests are held on the yacht as the police investigate, at least Addie can peruse Zach’s father’s rare books library on board. A copy of Agatha Christie’s first Hercule Poirot novel, The Mysterious Affair at Styles, provides a clue that the killer may still be on the ship—but narrowing down the suspects without becoming the next victim may prove a truly Herculean task . . .
