A Death Ruled Too Quickly
Detective Arthur Grayson, Male, 44, was found dead in his study flat on the morning of November 9th. The official ruling came fast: suicide by hanging. His colleagues at City PD say that's impossible.
Grayson had spent three weeks buried in the Hollow Crown Murders — a mass killing at the Hollow Crown pub on Halloween night that left five people dead and no witnesses willing to talk. He was, by all accounts, three days from closing the case.
"He called me the night before. Said he finally had something solid. Said someone was wearing one of the hats."
— Statement attributed to Detective Elias Mercer, November 9th, 1956.

The Hollow Crown Murders — Background
Five Dead. No Motive. No Witnesses.
On the night of October 31st, five people were killed at the Hollow Crown pub. The victims had no known connection to each other. Police initially suspected a robbery gone wrong, but nothing was taken. The killings were methodical. Deliberate. Someone chose that pub, that night, and those five people.
Grayson had been working a theory: the victims were not random. They were placed there. His notes suggest he had identified a suspect — but his case folder was found empty when officers arrived at his flat. The pages are missing.

The following items were recovered during investigation. Study carefully.
Five persons were found dead late Thursday evening at the Hollow Crown public house on Maret Street, in what investigating officers are describing as the most shocking act of violence the city has seen since the war years.
The deceased — none of whom have yet been formally identified pending notification of next of kin — were discovered by the landlord, Mr. T. Greer, at approximately ten o'clock in the evening, when he returned from the cellar to find the bar in disarray.
"I heard nothing," Mr. Greer told this correspondent. "The wireless was on. When I came up they were all… it was quiet. Too quiet."
Police arrived at 10:14 PM. A Metropolitan spokesman confirmed that five adults, three male and two female, were pronounced dead at the scene. Cause of death has not been disclosed pending post-mortem examination. No weapon was recovered.
Sources within the department have indicated the victims appear to have known one another, though this has not been confirmed officially. A receipt recovered from the scene suggests the group had been drinking together at a single table for some hours prior to the incident.
One detail has particularly troubled senior officers: bar staff report that a sixth person — described only as a man in a flat cap who paid the bill — departed the premises approximately twenty minutes before the killings were discovered. This individual has not yet been identified or traced.
"We are pursuing all lines of inquiry," a police spokesman said on Friday morning. "We would ask that anyone with information come forward at the earliest opportunity."
A reward of five pounds has been offered for information leading to an arrest.
Who removed the pages from Graysons notebook? The notebook was on Grayson's desk when PC Walsh arrived at 6:04 AM. The estimated time of death is between 11 PM and 1 AM. That is a window of five to seven hours in which someone — not necessarily the killer — had access to that flat and those pages.
The notebook pages are missing. The case folder is empty. Someone knew exactly what Grayson had written and exactly which pages to take. That level of knowledge suggests either direct involvement — or someone else watching the investigation from the inside.
Who removed the pages from Arthur Grayson's notebook? And what did they contain that was worth the risk of returning to the scene?

Dorian Law
Gender / Age
Male, 38
Occupation
Freelance Logistics Consultant
Address
11 Ashford Terrace, City Centre
Law has lived here six years, working independently for unnamed clients. Neighbors call him polite but private—the kind of man who habitually ducks his head under low doorframes. His name surfaced twice in the Hollow Crown canvass, though he denied any connection to the pub. He was unusually cooperative during his interview, looming over the desk as he politely leaned down to sign his statement.
⚠ During interview, Law volunteered that he "doesn't own hats — never has." No officer had asked about hats. Investigators questioned Law regarding cigarette remnants recovered from Grayson’s study. Law admitted he had recently attempted smoking “out of curiosity,” but described the experience as “disgusting” and claimed he abandoned the habit immediately. He further stated he had purchased a cheap ashtray days prior solely for the attempt.

Female, 31
Occupation
Investigative Journalist — City Evening Post
Address
Flat 9, Colston House, Briar Road
Frey had been investigating the Hollow Crown Murders independently — ahead of police — for a piece she claims was never published. She knew Grayson personally: two confirmed meetings at a café near the precinct. A note found in Grayson's coat reads: "H.F. knows more than she said — do not approach directly."
⚠ Telephone exchange records confirm a three-minute call between Frey’s residence and Grayson’s flat at 11:47 PM on November 8th — minutes before Grayson’s estimated time of death.

Constantine Butcher

Male, 45
Occupation
Former Bouncer — currently unemployed
Address
22B Greywell Street
A regular at the Hollow Crown for nearly a decade. Knew the staff and many regulars by name. Physically imposing — tall, broad, typically wears a dark coat. Two prior arrests on record. A witness described someone matching his exact description leaving the pub via the side door at approximately 9:50 PM on the night of the murders.
⚠ A Mireille No.7 cigarette stub was recovered from Grayson's flat. Butcher smokes Mireille No.7 — however, an officer noted the stubs appeared unsmoked at the filter end, as if stubbed out quickly. Butcher also has an unexplained 40-minute gap in his alibi.
POI — 004
Missy Lopez
Gender / Age
Female, 27
Occupation
Pharmacy Technician — Aldgate Chemist
Address
Flat 2, 38 Pennywort Lane
Lopez came to attention because her name appeared on a handwritten list in Grayson's recovered notes — context unknown. No prior record. No known connection to the victims. Worked a late shift the night of October 31st at the Aldgate Chemist, a four-minute walk from the Hollow Crown. Visibly distressed during her interview.
⚠ Lopez left work at 9:47 PM but did not arrive home until 10:52 PM. She gave three different explanations for the gap. The truth remains unconfirmed. Officers also noted Lopez is unusually tall and broad in build compared to other women, a detail that may be relevant to eyewitness descriptions of a large figure seen near the rear streets that evening.
Alibi Review
Cross-reference with evidence filesDorian Law
Partially Verified"I was home all evening on October 31st. I ordered food — the receipt will confirm. I didn't go out at all that night."
Food delivery receipt timestamped 7:14 PM confirms his location early evening only. No evidence places him at home between 9 PM and midnight. On second questioning, his account shifted from "never been" to "not in years" regarding the Hollow Crown — a contradiction he did not flag himself. Investigators additionally noted traces of dried mud along the outer heel and sole of Law’s boots during interview. When questioned, Law claimed he had slipped near a construction alley several streets from his residence earlier that evening. Officers briefly considered whether the residue could relate to the unidentified bootprint recovered from Grayson’s study, though no definitive comparison was made. He volunteered, unprompted, that he "doesn't own hats." No officer had raised the subject.
Harper Frey
Partially Verified"I was at my bureau all night on November 8th, working on a manuscript draft. My Remington typewriter was clattering the entire evening. I didn't leave the flat."
A local courier confirmed delivering a fresh typewriter ribbon to her flat at 11:30 PM, and neighbors report hearing the keys until midnight—consistent with her stated alibi. However, the building's switchboard log shows an unlisted outgoing call was placed from her flat at 11:47 PM, but the operator's record of the destination trunk was deliberately torn out. Frey claims it was an accidental disconnection. Grayson's coat note — "H.F. knows more than she said" — suggests he had concerns about her prior to his death. Her knowledge of the investigation appears to exceed what she disclosed.
Constantine Butcher
Alibi Gap Confirmed"I wasn’t anywhere near the Hollow Crown that night. Spent the evening round Rory’s listening to the football broadcast. Left my place at seven and didn’t get back until well after midnight."
Initial testimony from Rory Nance supported Butcher’s account. During a second interview conducted on November 11th, Nance admitted Butcher had left the flat for approximately forty minutes shortly after 9 PM and returned visibly agitated. Butcher later dismissed the discrepancy, claiming he had “forgotten the walk entirely.” The unexplained absence places him within travelling distance of the Hollow Crown during the estimated time of the murders. Additionally, cigarette remnants recovered from Grayson’s study were identified as Mireille No.7 — a French brand reportedly favoured by Butcher. Investigators noted the cigarettes had been lit but barely smoked, suggesting the smoker left abruptly or was interrupted mid-conversation. During follow-up questioning, Butcher mentioned having slipped along a muddy side street while returning to Rory Nance’s flat that evening, resulting in visible dirt along the heel of his boots. Officers briefly considered whether the mud could correspond with the unidentified bootprint recovered from Grayson’s study, though no formal match was established.
Missy Lopez
Gap Unexplained"I finished my shift just before ten and walked straight home alone. I didn't see or hear anything."
Timekeeping records from her employer confirm she left work at 9:47 PM. However, multiple witness accounts place her arrival home at approximately 10:52 PM — over an hour unaccounted for. Her explanations for this gap have been inconsistent across three separate interviews. She became visibly distressed during questioning and requested the interview be ended early. Her name appears in Grayson’s personal notes without clear context. Investigating officers noted her emotional response appeared more consistent with shock or grief than deception. During initial questioning, Lopez stated that her boots were “covered in mud” after leaving work and that she had left “muddy footprints everywhere” along her route home. No corresponding trail was ever recovered or formally documented by responding officers.
