To answer directly: The Beast in Me takes place primarily in a wealthy, wooded suburban neighborhood setting around Oyster Bay, New York, where the neighboring real estate mogul Nile Jarvis moves in next door, triggering the tense cat-and-mouse dynamic with the author Aggie Wiggs. What this means contextually:

• Setting focus: The series centers on the neighborhood and adjacent properties in the Oyster Bay area, mixing private home interiors with the surrounding upscale, tree-lined exteriors.
• Atmosphere: The location choice—affluent suburb with a sense of secrecy and wealth—amplifies the psychological tension between Aggie Wiggs and Nile Jarvis.
• Narrative geography: While the core action unfolds in the immediate vicinity of Aggie’s home and Nile’s residence, occasional scenes extend to related nearby locales tied to the mystery around Nile’s past and his wife’s disappearance.

If you’d like, I can tailor this to a specific aspect (e.g., how the setting influences character dynamics, or how the location impacts suspense and plot progression).
