I §1 Definition + structural principles
Mystery / noir investigation: dark procedural prose centred on uncovering what is hidden. In the Republic's universe this translates into inquisitorial investigation: suspected heresy, disappearance on a station, counter-espionage, doctrinal fraud, internal coercion. The tone is cold, paranoid, patient.
- Real procedure. The investigation follows plausible steps: record, interview, evidence collection, confrontation, Actum Gladii or absolution. No magical leaps.
- Fallible investigator. The Inquisitor or Commissar can be wrong. Can be manipulated. Doctrine guards against this, but does not exempt from duty.
- Hostile city. The classic noir “city” is here the station, the frigate, the industrial deck. Opaque geography, metal alleyways, people who know and do not tell.
- Doctrinal suspicion. The reading angle is doctrinal: what deviates, what hides, what breaks oath.
II §2 Genre-specific safeguards + technical
- Torture is not a valid investigative technique. Hard interrogation is admissible; descriptive enthusiasm for prolonged suffering is not.
- No real-person identification. Cases do not trace real crimes or real public-figure profiles.
- No real-world conspiracy theories. Fictional conspiracies stay inside the Republic's universe (rival Directorates, heretical cells, cargo syndicates).
- Possible resolution. The case may close with conviction, with Non Admittendi, or with ambiguity — but not with gratuitous nihilism. There is always an Actum even when incomplete.
Technical principles
- Sober internal voice. If first person, internal monologue in short sentences, no self-pity. If third person, strict internal focalisation.
- Probing dialogue. Short questions, long pauses. The interrogator listens more than she asks.
- Administrative detail as clue. A serial number, a bell, a manifest, a misfiled photograph.
- Atmosphere by light and sound. Weak lighting; corridor echo; ventilation hum. Noir is also ergonomy: cold chair, reheated coffee, creased uniform.
- Narrative patience. Noir does not run. Each chapter lays a layer. The revelation, when it comes, seems inevitable.
III §3 Example (interrogation)
Room three held two chairs, a table, two water glasses, and an empty ashtray no one had used in a long time. Inquisitor Ekhart entered first. She sat. She did not greet.
The witness — Ferraz, M., cargo operator, deck seven — entered three minutes later, escorted. The insignia was straight. The hands were not.
“Operator Ferraz,” said Ekhart, without raising her eyes from the dossier. “Confirm that yesterday, at the third bell, you were on deck five.”
“Confirmed, Inquisitor.” — “On duty?” — “Yes.”
Ekhart took a note. She did not comment. She turned the page. “Confirm your shift ended at the second bell.”
Ferraz hesitated half a second. It was enough. “Yes, Inquisitor.”
Ekhart set down the pen. She looked at him for the first time. “Then tell me what you were doing on deck five one bell after your shift ended.”
Ferraz did not answer. The next bell took its time. Ekhart waited.
Pro Humanitate. Semper Vigilo.
So speaks the Vigil.
