The Pale Blue Eye (2023) on Netflix

A world-weary detective is hired to investigate the murder of a West Point cadet. Stymied by the cadets' code of silence, he enlists one of their own to help unravel the case - a young man the world would come to know as Edgar Allan Poe.

At West Point Academy in 1830, the calm of an October evening is shattered by the discovery of a young cadet's body swinging from a rope just off the parade grounds. An apparent suicide is not unheard of in a harsh regimen like West Point's, but the next morning, an even greater horror comes to light. Someone has stolen into the room where the body lay and removed the heart.
