The Vineyard Files

The truth is in the details.

Cooperative mystery case files. A real folder of evidence you spread across the table and solve with the people you like, at your own pace.

The Vineyard Files

A mystery you can hold in your hands and pass across a table.

Each case is a real file placed in your hands: documents, photographs, maps, notes, reports and layered clues that slowly give up the truth. Not a party game. Not a puzzle you throw away. A case you solve.

I

Real paper. Real folders.

Evidence that doesn’t sort itself, printed to be handled, spread out, argued over and pieced together.

II

A real island.

Every case is set on Martha’s Vineyard. The ferry, the harbor and the streets are part of the logic, the mood and the reveal.

III

Endings that feel earned.

Smart clue logic and twists that are surprising but fair. You don’t just read a story. You solve one.

Case 001, The Wrong Tide, is the first file. Here it is, up close.

From Case 001 · Confidential

The Wrong Tide

“The tide keeps its own record. It does not always agree with the one on paper.”

Every case opens the same way: a briefing prepared for the investigator now in possession of the file. This is the first page of Case 001, word for word.

Doc 01 · Detective briefingCase No. EPD-25-0914-H

Detective,

On the morning of September 14, 2025, the body of prominent Martha’s Vineyard businessman and donor Graham Vale was recovered along the Edgartown waterfront, hours after a high-profile charity fundraiser attended by several of the island’s most visible figures.

The official theory has shifted more than once. Statements conflict. Timelines fray under pressure.

Some investigators believe Graham Vale was killed near where he was found. Others are no longer sure that the harbor was the true scene at all.

Your task is to determine:

  1. Who killed Graham Vale.
  2. How the murder happened.
  3. Why it happened.
  4. Which pieces of evidence prove it.

How every case plays

You are reviewing a real case file. Read carefully. Trust nothing automatically.

  1. 01
    Doc 01

    Start with the briefing.

    The Detective Briefing is your invitation into the case. It tells you the setting, the victim, and what is being asked of you. Read it first, even if everything else looks more interesting.

  2. 02
    Docs 02 to 05

    Read the police file.

    Case summary, incident report, evidence inventory and the medical examiner’s report. The facts that are not in dispute. Note what stands out, but do not draw conclusions yet.

  3. 03
    Docs 06 to 15

    Get to know the people.

    Five dossiers and five witness statements. People reveal themselves not only in what they say, but in what they refuse to say, and in what they say with too much care.

  4. 04
    Docs 16 to 27

    Work the evidence.

    Phone logs, text messages, the ferry schedule, the tide chart, the harbor map, scene photographs and a case from 2016. The small details that make or break a theory.

  5. 05
    Doc 23

    Name the killer.

    Write it down on the Final Accusation Worksheet. Name the killer. Name the scene. Cite the evidence. Reconstruct the sequence in your own words.

  6. 06
    Doc 25

    Break the seal.

    Open the sealed solution and see how close you got. Not a moment before. Once you read the answer, you cannot un-read it.

The sealed Hints envelope from Case 001
If you get stuck

Four hint cards, sealed.

Open Hint One first, and only open the next if you are still stuck. None of them name the killer.

One important rule

Do not open the sealed solution before you have completed the accusation. The game is best played in order. Trust the order.

No app, no host and no narrator in Case 001. Just the case and the people willing to solve it.

Set on Martha’s Vineyard

The harbor is real. The ferry is real.

The streets are where we say they are. The people inside the file are not. Every case is set somewhere on the island, and the island is part of the logic, the mood and the reveal.
