In THE ALIENIST: ANGEL OF DARKNESS, Sara Howard has opened her own private detective agency and is leading the charge on a brand-new case. She reunites with Dr. Kreizler, the formidable alienist, and John Moore, now a New York Times reporter, to find Ana Linares, the kidnapped infant daughter of the Spanish Consular. Their investigation leads them down a sinister path of murder and deceit, heading towards a dangerous and elusive killer. As in The Alienist, the series shines a light on the provocative issues of the era — the corruption of institutions, income inequality, yellow press sensationalism, and the role of women in society — themes that still resonate today.
