The Process

How It Works

Each mystery unfolds like a real investigation, phase by phase.

01

Open the Case

Review initial evidence: crime scene reports, witness statements, and the first wave of clues.

02

Solve Puzzles

Hidden codes and patterns within the evidence unlock new phases of the investigation.

03

Dig Deeper

Each unlocked phase reveals new letters, transmission logs, and secrets. Cross-reference everything — the truth hides in the details.

04

Accuse

When you have the full picture, name the killer, the method, and the motive. You only get one shot — make it count.

The Evidence

Real Clues, Real Investigation

Every piece of evidence is designed to feel authentic.

Witness Statements

Read through official testimony, complete with rubber stamps, ruled lines, and typewriter text. Spot the inconsistencies.

Personal Letters

Handwritten correspondence on aged parchment, complete with coffee stains and fold marks. The personal lives of your suspects hold secrets.

Official Documents

Death certificates, inventory audits, and background checks. The bureaucratic paper trail often holds the critical detail everyone else missed.

Radio Transmissions

Green-on-black terminal readouts with flagged frequencies and coded messages. Something is being hidden in the static.

Physical Evidence

Torn notes, smuggling schedules, and gambling IOUs — displayed on evidence mats with numbered tags, just like the real thing.

Medical Reports

Toxicology results, inventory audits, and clinical findings. The science doesn't lie — but someone is hoping you won't read closely enough.
