Berenice

"Berenice" is a short horror story by Edgar Allan Poe, published in 1835. The story follows a man named Egaeus who is preparing to marry his cousin Berenice. He has a tendency to fall into periods of intense focus during which he seems to separate himself from the outside world. Berenice begins to deteriorate from an unnamed disease until the only part of her remaining healthy is her teeth, which become the object of Egaeus' obsession. Berenice is buried, and Egaeus continues to contemplate her teeth.
One day Egaeus wakes up from a period of focus with an uneasy feeling, and the sound of screams in his ears. A servant startles him by telling him Berenice's grave has been disturbed, and she is still alive; but beside Egaeus is a shovel, a poem about "visiting the grave of my beloved" and a box containing 32 blood-stained teeth.
