The bestselling author of Girl Waits with Gun brings the real-life escapades of the famous crime-fighting Kopp sisters to life in this extraordinary novel that is "perfect for book groups" (Booklist). Deputy sheriff Constance Kopp stands up to the “morality” laws of 1916, defending the independent young women in her prison against dubious charges when no one else will. From the patriotic Edna Heustis, who left home to work in a munitions factory, to the sixteen-year-old runaway Minnie Davis, these and other publicly shamed women who were packed off to a state-run reformatory find an unlikely ally in Constance, who uses her authority — and occasionally exceeds it — to investigate and defend them at all costs. But it's Constance's sister Fleurette who forces her to reckon with her own ideas of how a young woman should and shouldn't behave. Set against the backdrop of World War I, and drawn from true characters and events, this novel is timeless in its themes of justice and equality, and is sure to delight fans of historical and detective fiction alike.

Life after the war takes an unexpected turn for the Kopp sisters, but soon enough, they are putting their unique detective skills to use in new and daring ways. Winter 1919: Norma is summoned home from France, Constance is called back from Washington, and Fleurette puts her own plans on hold as the sisters rally around their recently widowed sister-in-law and her children. How are four women going to support themselves? A chance encounter offers Fleurette a solution: clandestine legal work for a former colleague of Constance’s. She becomes a “professional co-respondent,” posing as the “other woman” in divorce cases so that photographs can be entered as evidence to procure a divorce. While her late-night assignments are both exciting and lucrative, they put her on a collision course with her own family, who would never approve of such disreputable work. One client’s suspicious behavior leads Fleurette to uncover a much larger crime, putting her in the unlikely position of amateur detective. In Miss Kopp Investigates, Amy Stewart once again brilliantly captures the women of this era—their ambitions for the future as well as the ties that bind—at the start of a promising new decade.

“A colorful and inventive adventure tale.”—Washington Post “It’s True Grit, New York style.”—New York Post “One of the best mystery novels of the year: wonderful and very entertaining.” —New York Journal of Books “Stewart deftly combines the rough-and-tumble atmosphere of early twentieth-century New York City with the story of three women who want to live life on their own terms.” —Library Journal, starred review In 1915, lady cops were not expected to chase down fugitives on the streets of New York City. But Constance Kopp never did what anyone expected. Constance and her sisters aren’t living the quiet life anymore. They’ve made headlines fighting back against a ruthless silk factory owner and his gang of thugs. After Sheriff Heath sees Constance in action, he appoints her as one of the nation’s first female deputies. But when a German-speaking con man threatens her position—and puts the honorable sheriff at risk for being thrown in his own jail—Constance will be forced to prove herself again. Based on the Kopp sisters’ real-life adventures, Girl Waits with Gun introduced the sensational lives of Constance Kopp and her sisters to an army of enthusiastic readers. This second installment, also ripped from the headlines, takes us farther into the riveting story of a woman who defied expectations, forged her own path, and tackled crime along the way. “A fast-moving, craftily written novel.”—BookPage “[An] irresistible madcap adventure.”—PopSugar “Stewart leaves the reader wondering about one mystery still developing unsolved . . . Readers will just have to wait—impatiently, no doubt—for book No. 3.”—Boston Globe

NATIONAL BESTSELLER. The first in the Kopps Sisters Novel Series, Girl Waits with Gun is an enthralling novel based on the forgotten true story of one of the nation’s first female deputy sheriffs. Constance Kopp doesn’t quite fit the mold. She towers over most men, has no interest in marriage or domestic affairs, and has been isolated from the world since a family secret sent her and her sisters into hiding fifteen years ago. One day a belligerent and powerful silk factory owner runs down their buggy, and a dispute over damages turns into a war of bricks, bullets, and threats as he unleashes his gang on their family farm. When the sheriff enlists her help in convicting the men, Constance is forced to confront her past and defend her family — and she does it in a way that few women of 1914 would have dared. A New York Times Editors' Choice “A smart, romping adventure, featuring some of the most memorable and powerful female characters I've seen in print for a long time. I loved every page as I followed the Kopp sisters through a too-good-to-be-true (but mostly true!) tale of violence, courage, stubbornness, and resourcefulness.”—Elizabeth Gilbert

Constance Kopp, America’s first female deputy sheriff, is back in another unforgettable romp by Historical Writers' Association-longlisted international bestseller Amy Stewart. While transporting a woman to an insane asylum, Deputy Kopp discovers something deeply troubling about her story. Before she can investigate, another inmate breaks free and tries to escape. In both cases, Constance runs instinctively toward justice. But 1916 is a high-stakes US election year, and any move she makes could jeopardize Sheriff Heath’s future — and her own. Constance’s controversial career makes her the target of political attacks. With wit and verve, book club favourite Amy Stewart brilliantly conjures the life and times of the real Constance Kopp to give us this ‘unforgettable, not-to-be messed-with heroine’ (Marie Claire).

The fearless Kopp sisters are back in another unforgettable romp by HWA-longlisted international bestseller Amy Stewart. It’s 1917, and the US Army is marching to join its allies in the First World War. Constance Kopp and her sisters may not be soldiers, but that doesn’t mean they can’t do their bit. All over America, women are banding together to create military-style training camps, and so the Kopp sisters leave their farm in New Jersey to learn some army discipline. In Kopp Sisters on the March, the women of Camp Chevy Chase face down the scepticism of the War Department, the double standards of a scornful public, and the very real perils of war. Once again, Amy Stewart has brilliantly brought a little-known moment in history to light.

Split apart by the war effort, the indomitable Kopp sisters take on saboteurs and spies and stand up to the Army brass as they face the possibility that their life back home will never be the same. The U.S. has finally entered World War I. Constance, the oldest of the Kopp sisters, is doing intelligence work on the home front for the Bureau of Investigation while youngest sister and aspiring actress, Fleurette, travels across the country entertaining troops with song and dance. Meanwhile, at an undisclosed location in France, Norma oversees her thwarted pigeon project for the Army Signal Corps. When her roommate, a nurse at the American field hospital, is accused of stealing essential medical supplies, the intrepid Norma is on the case to find the true culprit. Determined to maintain their sometimes-scratchy family bonds across the miles, the far-flung sisters try to keep each other in their lives. But the world has irrevocably changed—when will the sisters be together again? Told through letters, Dear Miss Kopp weaves the stories of real-life women a century ago, proving once again that “any novel that features the Kopp sisters is going to be a riotous, unforgettable adventure” (Bustle).
