The Alienist, Caleb Carr
Perfect for a Rainy Day Because: This smart, gloomy thriller doesn’t really have that “sunny day” kind of feel. Plus, Carr uses rain very effectively as scenic background.
Plot: It’s the late 1890’s, and NYC police have just discovered the country’s first serial killer. A team of experts, including a brilliant therapist/scientist, a wannabe female detective, and a re-imagined (and badass) Theodore Roosevelt as the then-NYC police commish set out to find the killer.
