A narrative investigation about family secrets, tested friendships and a room that should have stayed locked.

case summary / 17-B

Every mystery
leaves a mark.

Lia finds a strange envelope at home. Inside, an old photograph and the number 17 point to a forgotten place at Horizon School: Locker 17 and, beyond it, room 17-B.

From there, every choice changes what she truly knows. Opening the envelope, telling Maya, examining the locker, searching the library or confronting her mother: nothing appears magically later. The clues build a different investigation for every player.

Between family dinners, old corridors and scenes in the basement, Lia meets a teacher hiding information, a principal trying to stop the search, and new witnesses: Augusto, Rafael and Clara. Even her mother's word search can reveal a letter, an envelope or the number 17.

At the final trial, you gather evidence and decide who to trust. The culprit may be Mother, Maya, the principal, the teacher, Augusto, Rafael, Clara or the mysterious figure. You may be right, accuse the wrong person, accuse no one or find the last envelope and reach the Complete Truth.
