Clara Wieland recounts the heartbreaking tale of her family in a detailed letter to a friend. Her father, a deeply religious man plagued by guilt for ignoring a missionary call, fell into a profound depression, ultimately meeting a tragic end. In a fateful visit to his meditation temple, he was inexplicably consumed by flames, muttering about an unseen force before he passed away. Not long after, Clara's mother died, leaving Clara and her brother Theodore as wealthy orphans cared for by a nurturing aunt.

Young Love and Familial Bonds

The siblings grew up alongside Catharine Pleyel, a charming and affluent young woman who captured Theodore’s heart. Their ensuing marriage allowed Wieland to inherit half of the family’s fortune, with Clara receiving the other half. Despite having their own homes, Clara lived close by, maintaining a lively and warm social connection with her brother and sister-in-law. The trio enjoyed long conversations, often held in the temple where their father had perished, though Theodore had a penchant for discussing morbid topics, much to Clara and Catharine’s discomfort. The circle was soon joined by Catharine's jovial brother Henry, whose cheerful nature contrasted with Theodore's somber demeanor. While Theodore embraced religious convictions, Henry valued intellectual freedom, yet their friendship remained unscathed by their philosophical differences.

Whispers of the Supernatural

As the family expanded with additional children, both biological and fostered, a bizarre incident pierced their idyllic life. One day, as Theodore approached the temple, he heard what seemed to be his wife’s voice warning of impending danger. Rushing back to the house, he found his wife had never left, and others confirmed her presence. While the family dismissed the voice as an oddity, Theodore became obsessed, unable to shake its chilling effect.

The Ghostly Voice

With news of a European inheritance, Henry encouraged Theodore to travel abroad with him, planning to reunite with a baroness who held his affections. During a persuasive walk one evening, they were interrupted by a voice, again Catharine’s, announcing the baroness's death. The impossibility of Catharine being there, coupled with later confirmation of the baroness's demise, left Theodore convinced of a supernatural intervention.

A Stranger’s Intrusion

In the wake of these eerie events, Clara encountered an enigmatic stranger, Carwin, whose appearance was disheveled yet whose voice was captivating. Over time, Carwin integrated into their group, dismissing the mysterious voices as harmless pranks. However, Clara's peace was shattered when she overheard two sinister voices plotting her murder. Terrified, she fled to Theodore's home, collapsing at his doorstep. Strangely, her brother and Henry were alerted by another mysterious voice, compelling them to her aid.

Dangerous Accusations

Henry insisted on staying at Clara’s home to protect her from unseen threats, yet the warnings continued, suggesting danger from her own brother. Meanwhile, Carwin, known to Henry from Spain, became a regular visitor. Tensions escalated when Henry, believing himself spurned by Clara, accused her of immoral behavior with Carwin. Devastated, Clara was unable to convince him of her innocence as she learned of Carwin's unsavory reputation. Her despair deepened upon receiving an ominous note from Carwin, prompting a reluctant meeting. However, upon arriving home, Clara discovered Catharine murdered, her lifeless body on Clara's bed.

The Tragic Unraveling

Theodore, acting erratically, entered the room, his speech exalted, pleading against performing the "sacrifice" demanded of him. The horror multiplied when Clara learned that her brother had also killed his own children. Taken to the city by friends, Clara gradually uncovered the full nightmare: Theodore, guided by a supposed divine voice, believed he was fulfilling a sacred duty by sacrificing his family. He felt no remorse, only...
