A USA Today bestseller! “[Penrose] mixes well-thought out mysteries, early forensic science, great details of the era and a slow burning attraction creating a compulsive read.” —The New York Public Library A thrilling new mystery novel from the acclaimed author of Murder at Queen’s Landing, perfect for fans of Deanna Raybourn and Anne Perry! In the fifth installment of Andrea Penrose’s acclaimed, atmospheric mystery series, the upcoming marriage of the Earl of Wrexford and Lady Charlotte Sloane promises to be a highlight of the season, if they can first untangle—and survive—a web of intrigue and murder involving the most brilliant scientific minds in Regency London… One advantage of being caught up in a whirl of dress fittings and decisions about flower arrangements and breakfast menus is that Charlotte Sloane has little time for any pre-wedding qualms. Her love for Wrexford isn’t in question. But will being a wife—and a Countess—make it difficult for her to maintain her independence—not to mention, her secret identity as famed satirical artist A.J. Quill? Despite those concerns, there are soon even more urgent matters to attend to during Charlotte and Wrexford’s first public outing as an engaged couple. At a symposium at the Royal Botanic Gardens, a visiting botanist suffers a fatal collapse. The traces of white powder near his mouth reveal the dark truth—he was murdered. Drawn into the investigation, Charlotte and the Earl learn of the victim’s involvement in a momentous medical discovery. With fame and immense fortune at stake, there’s no shortage of suspects, including some whose ruthlessness is already known. But neither Charlotte nor her husband-to-be can realize how close the danger is about to get—or to what lengths this villain is prepared to go . . .

An exquisite seaside resort, an eccentric group of British aristrocrats on holiday, and rich 1930's detail lay the setting for this stupendous debut mystery of manners by a young librarian

By the New York Times bestselling author of The Bone Clocks and Cloud Atlas | Longlisted for the Man Booker Prize Selected by Time as One of the Ten Best Books of the Year | A New York Times Notable Book | Named One of the Best Books of the Year by The Washington Post Book World, The Christian Science Monitor, Rocky Mountain News, and Kirkus Reviews | A Los Angeles Times Book Prize Finalist | Winner of the ALA Alex Award | Finalist for the Costa Novel Award From award-winning writer David Mitchell comes a sinewy, meditative novel of boyhood on the cusp of adulthood and the old on the cusp of the new. Black Swan Green tracks a single year in what is, for thirteen-year-old Jason Taylor, the sleepiest village in muddiest Worcestershire in a dying Cold War England, 1982. But the thirteen chapters, each a short story in its own right, create an exquisitely observed world that is anything but sleepy. A world of Kissingeresque realpolitik enacted in boys’ games on a frozen lake; of “nightcreeping” through the summer backyards of strangers; of the tabloid-fueled thrills of the Falklands War and its human toll; of the cruel, luscious Dawn Madden and her power-hungry boyfriend, Ross Wilcox; of a certain Madame Eva van Outryve de Crommelynck, an elderly bohemian emigré who is both more and less than she appears; of Jason’s search to replace his dead grandfather’s irreplaceable smashed watch before the crime is discovered; of first cigarettes, first kisses, first Duran Duran LPs, and first deaths; of Margaret Thatcher’s recession; of Gypsies camping in the woods and the hysteria they inspire; and, even closer to home, of a slow-motion divorce in four seasons. Pointed, funny, profound, left-field, elegiac, and painted with the stuff of life, Black Swan Green is David Mitchell’s subtlest and most effective achievement to date. Praise for Black Swan Green “[David Mitchell has created] one of the most endearing, smart, and funny young narrators ever to rise up from the pages of a novel. . . . The always fresh and brilliant writing will carry readers back to their own childhoods. . . . This enchanting novel makes us remember exactly what it was like.”—The Boston Globe “[David Mitchell is a] prodigiously daring and imaginative young writer. . . . As in the works of Thomas Pynchon and Herman Melville, one feels the roof of the narrative lifted off and oneself in thrall.”—Time
