Her encrypted phone is your only crime scene. Expose the truth.

A contractor is dead. The certificate says cardiac arrest. Her phone says otherwise.

A radio host vanished hours before going live with the biggest secret campus had ever heard.

A 19-year-old vanishes mid-storm, leaving her phone behind and 47 seconds of missing footage. Her final warning: don't trust the person who finds her.

A student is found dead in a locked, undisturbed apartment. No weapon, no forced entry. One notification is still on the screen: "You shouldn't have looked."

A man is dead on a kitchen floor, and nobody called for help for nineteen minutes. Both witnesses' phones are completely honest — and neither one is enough.
No simulated clues or abstract mini-games. You navigate an exact recreation of the suspect's smartphone — examining voice memos, text threads, GPS logs, and deleted notes.
