About
The night shift at Greywater Major Crimes has begun. There is a file on your desk, and the truth is only as strong as the evidence behind it.
Greyline is a detective game where you do not pick the answer. You build it.
SEARCH THE SCENE
Photographs are wider than your phone: drag, zoom and hold the lens still. Clues are unmarked. Your attention is limited, and what you miss stays missed.
BUILD YOUR DEDUCTIONS
Linking two findings opens a question, not an answer. You decide which reading you believe; the game never tells you whether you are right.
QUESTION THE SUSPECTS
Every witness has composure and trust. Tells flash for seconds. Show evidence too early and the story bends around it.
DEFEND YOUR REPORT
You write the accusation from your own deductions, then face three objections and answer each with evidence you hold. The right name alone is not a strong result: method, timing and independent corroboration matter too.
STANDALONE CASES
Examine each scene, question witnesses and defend your own report with evidence.
