CASE 01 / MURDER
The Second Carbon
An archive director is found dead before a meeting with the trustees. Four visitors have an explanation. The records tell a different story.
A photograph appears to place one visitor safely in reception. A badge list points elsewhere. Work through statements, passage records and a disputed invoice to explain the killing and find the document the director meant to preserve.

WATCH BEFORE YOU BUY
Step inside The Second Carbon.
This is the actual ten-second opening from the Digital Edition, with original instrumental music. Press play to watch; use the player to mute or adjust the volume.
The game itself is a reading-and-deduction investigation. The clip sets the scene; it contains no clues or solutions.
Prefer paper? The included Print Edition needs only 14 investigation pages, in black-and-white on A4 or US Letter. Keep hints and answers on screen.
