“A cruel and cunning mystery. . . . Plot-twisting, mind-altering and monstrously funny.” —The New York Times Book ReviewThe latest gripping psychological thriller from Edgar Award winner Alex MarwoodWhen a child goes missing at an opulent house party, it makes international news. But what really happens behind closed doors? Twelve years ago, Mila Jackson’s three-year-old half-sister Coco disappeared during their father’s fiftieth birthday party. Her identical twin Ruby was left behind as the only witness. The girls’ father, Sean, was wealthy and influential, as were the friends gathered at their seaside vacation home for the weekend’s debauchery. The case ignited a media frenzy and forever changed the lives of everyone involved. Now, Sean Jackson is dead, and the people who were present that terrible night must gather once more for a funeral that will reveal that the secrets of the past can never stay hidden. Perfectly paced all the way through its devastating conclusion, The Darkest Secret is one that fans of Gillian Flynn and Liane Moriarty won't be able to put down.“As much a black comedy of contemporary bad manners as psychological thriller, The Darkest Secret is a triumph and a treat.” —The Irish Times From the Trade Paperback edition.
