Nancy Allen

Nancy Allen is an American novelist and former prosecutor whose legal career in the Missouri courts directly informs her crime fiction, most notably the Ozarks-set legal thriller series featuring prosecutor Elsie Arnold and, in later collaborative work, Ruby Bozarth. Allen spent years as an assistant prosecuting attorney handling major felony cases before moving into legal academia and full-time writing, giving her courtroom scenes a level of procedural accuracy grounded in direct professional experience. She partnered with James Patterson as a co-author, contributing her prosecutorial background to Patterson's high-volume collaborative fiction while continuing to publish her own solo legal thrillers rooted in small-town Missouri settings. Her writing is noted for grounding its courtroom drama in the specific social and economic textures of rural and small-city America, a perspective less commonly foregrounded in mainstream legal thrillers. Allen has taught law and continues to write, balancing her academic legal work with an active fiction career spanning both her own original Ozarks series and collaborative Patterson projects.
