The Fog at Blackwood Manor: A 1954 Detective Mystery Case File

A locked study. A poisoned tumbler of vintage port. Four airtight alibis—and a killer hidden in the coastal mist.

Step directly into October 1954 as a lead investigator for the East Coast Constabulary. Lord Arthur William Blackwood has been found dead at his mahogany writing desk inside Blackwood Manor.

The study door was firmly locked from the inside, the storm was howling over the Essex marshes, and every suspect present swears they could not have committed the crime.

This is a physical, fair-play tabletop mystery designed to be solved entirely through real forensic documents, period transit ephemera, suspect interviews, and sharp logic.

No apps, no screens—just you, a dossier of evidence, and a trail of paper clues.

What’s Inside the Case Dossier

Every component is rendered with period-accurate 1950s typography and authentic constabulary styling:



• Official Constabulary Incident Summary Sheet: Det. Insp. Miller’s preliminary scene notes detailing the locked room, timeline of discovery, and recovered physical evidence.

• County Pathologist Toxicological Summary: The confidential post-mortem memorandum establishing potassium cyanide as the cause of death and narrowing the lethal window to minutes.

• 4 Suspect Statements & Identification Mugshots: Dual-angle 1950s police photo cards clipped directly to the interrogation statements of Charles Edward Blackwood (Nephew), Miss Evelyn Clara Reed (Private Secretary), Mrs. Martha Higgins (Head Housekeeper), and Dr. Julian Vance, MD.

• Crime Scene Survey & Floor Plan: A scaled architectural draughtsman layout of the West Wing, ground-floor passages, and exterior cliff terrace.

• The Coastal Chronicle Clipping: The front-page Monday news report detailing the structural damage to the viaduct and coastal rail cancellations.

• Physical Travel Ephemera: Authentic replica British Railways platform ticket and Route 14 Omnibus stub, complete with local bus timetable extract.

• The Torn Will Fragment: A hand-torn memorandum revealing Lord Arthur’s final instructions regarding his disinherited nephew and clinic finances.

• Sealed Constabulary Findings Envelope: A wax-sealed brown kraft envelope containing the full case debrief and formal arrest warrant—strictly marked DO NOT OPEN UNTIL YOU HAVE NAMED THE KILLER.
