The Platinum Floor
A junior executive is found dead in the executive washroom. An investigation into the final 90 minutes of the executive floor is initiated, cross-referencing physical access logs, digital trails, and the accounts of senior partners to reconstruct a timeline from competing records and statements.
Initial Crime Scene
The corridor's blue-white fluorescent tubes hum at a low, constant frequency, casting sterile light on polished floor tiles that reflect distorted, moving patterns. A key card swipe log prints from the security desk thermal printer, its soft whirring the only mechanical sound. The scent of ozone and warm electronics drifts from the sub-basement. Three visual markers dominate: the row of RFID scanners lining the office doors, the analog CCTV unit with its single red recording light in the corner, and the encrypted email headers flickering on a distant terminal screen.
Crime Scene Environment
Lighting is sterile and blue-white, sourced from high-frequency fluorescent tubes. Humidity is low and controlled, with a cool, dry air temperature maintained by the central ventilation system. Acoustic density is moderate, characterized by the constant hum of server cooling fans, the low drone of the ventilation system, and the periodic, soft chirp of key card readers.
Investigation Constraints
Biometric key card scanners (RFID/NFC), encrypted internal comms (proprietary closed-circuit email/pager), physical server room logs (thermal printouts), corporate internal memos (printed & carbon-copy), analog CCTV with limited digital timestamping, encrypted file storage (mainframe access codes).
