Charlotte Holmes—aka Sherlock Holmes—becomes entangled in a puzzling missing person case that hits close to home for her beloved Mrs. Watson in this Victorian-set mystery from the USA Today bestselling author of A Ruse of Shadows. It’s been three years since Charlotte Holmes struck a decisive blow against Moriarty's operations in Britain, three years of relative calm and benign developments. In a buoyant mood, everyone gathers at Lord Ingram's seaside cottage in North Devon for what promises to be a perfect summer holiday. Until Mrs. Watson receives an invitation from Mrs. Carstairs, her long-estranged sister, to attend a house party nearby. Mrs. Carstairs has married spectacularly well. She is the mistress of a great manor, a doyen of all domestic arts, and still an unforgettable beauty. Now she clamors for a reconciliation with her sister. Mrs. Watson does not trust Mrs. Carstairs' motives. Yet she cannot help but feel tremors of the old admiration for this once-beloved sister. Then Mrs. Carstairs disappears without a trace. The next day a woman is discovered floating on the waves, her build and coloring matching those of Mrs. Carstairs. But her husband insists that the corpse fished out of the Bristol Channel cannot be his wife. So where is the real Mrs. Carstairs? Would she have purposely dragged Mrs. Watson into a murder investigation? Or was it Sherlock Holmes' involvement that she needed from the very beginning?

USA Today-bestselling author Sherry Thomas decided years ago that her goal in life is to write every kind of book she enjoys reading. Thus far she has published romance, fantasy, mystery, young adult, and three books inspired by the martial arts epics she grew up devouring. Her books regularly receive starred reviews and best-of-the-year honors from trade publications, including such outlets as the New York Times and National Public Radio. A Study in Scarlet Women, A Conspiracy in Belgravia, and The Hollow of Fear, the first three entries in her gender-bending Lady Sherlock historical mystery series, are all NPR best books of the year. The Magnolia Sword, her 2019 release, is the first young adult retelling of the original Ballad of Mulan in the English language. Sherry emigrated from China at age 13 and English is her second language. “Sherry Thomas has done the impossible and crafted a fresh, exciting new version of Sherlock Holmes. From the carefully plotted twists to the elegant turns of phrase, A Study in Scarlet Women is a splendid addition to Holmes’s world. This book is everything I hoped it would be, and the next adventure cannot come too soon!” —Deanna Raybourn, New York Times bestselling author “Thomas weaves a lush, intricate fantasy world around a gorgeous romance that kept me riveted until the very last page. What a breathtaking journey!” (Marie Lu, New York Times bestselling author of the Legend series ) "Sherry Thomas is the most powerfully original historical romance author writing today."—Lisa Kleypas, New York Times bestselling author Visit Sherry at her website Follow Sherry on twitter Find Sherry on Facebook
