1. Presenting Condition & Physical Description
Subject M. was a 23-year-old male of aristocratic lineage, noted for his intelligence and physical beauty. The anomaly, designated Subject M-B, was located on the posterior aspect of his head, facing backwards.
Subject M-B presented with the following confirmed characteristics:
A fully developed female face, possessing classic features described in contemporaneous notes as "strikingly beautiful."
A complete set of functional facial muscles, allowing for a full range of expression, including smiling, sneering, and weeping.
Intelligent, mobile eyes that tracked observers independently of Subject M.'s own vision.
A functional vocal apparatus. Unlike common parasitic twins, M-B possessed a low, distinct voice, capable of fluent speech.
2. Case History & Behavioral Notes
The relationship between Subject M. and M-B was documented as profoundly antagonistic. Subject M. reported that M-B was "never silent," whispering throughout the night, preventing restorative sleep.
Key behavioral observations from personal staff and the attending physician, Dr. William Severs, include:
M-B's discourse was consistently described as "blasphemous," "obscene," and filled with "dreadful temptations." It allegedly recited obscure historical facts and revealed secrets about individuals in Subject M.'s vicinity, knowledge which Subject M. himself could not have possessed.
Subject M. was never observed to take nourishment, yet M-B was noted to "flush with color" or appear "pale and sullen" depending on Subject M.'s emotional state, suggesting a shared, anomalous circulatory system.
Attempts to sedate Subject M. with morphine proved ineffective at silencing M-B, which would instead sing "dissonant lullabies" while the primary subject was unconscious.
3. Theories and Hypotheses
The nature of M-B's consciousness remains the primary enigma.
Parasitic Twinning: The standard explanation is insufficient, as it does not account for the independent, antagonistic consciousness or the disparate knowledge base.
Neuropsychological Manifestation: A radical theory suggests M-B was a physical manifestation of Subject M.'s own repressed psyche or a severe dissociative identity disorder given biological form. This is considered speculative.
External Attachment: The most classified hypothesis posits that M-B is not a twin at all, but a separate entity that grafted onto the host in utero, forming a parasitic symbiotic relationship to experience the physical world.
4. Final Disposition & Post-Mortem Events
Subject M. was found deceased in his library from a confirmed overdose of laudanum, ruled a suicide. A note in his handwriting was recovered, requesting that M-B be "destroyed before my burial... lest it continues its whispers from within the coffin."
The final observation, per Dr. Severs, remains unverified but is consistent across all witness testimonies: upon confirmation of Subject M.'s death, the face of M-B was said to have contorted into a mask of "triumphant malice" for a period of several seconds before all muscular activity ceased.
All requests for a post-mortem examination were denied by the family. The body was interred in a private, unmarked vault on the family estate. All official records were subsequently sealed by order of the Crown's Privy Council.
Conclusion: The case of Edward M. represents a unique and unresolved paradox. It stands at the intersection of teratology and parapsychology. The confirmed sentience and antagonism of Subject M-B challenge fundamental understandings of consciousness and identity. The full truth was, by all accounts, buried with the subject.
