Years ago, a dead boy mysteriously disappeared after a bomb blast, leaving only traces of blood at the scene. Now, promising clues have shown up, but not everyone wants you to find the boy. ”Keepers of Evil” is the third part of the Hunt for Maria trilogy. 50 Clues® is an award-winning immersive puzzle game that offers the experience of an escape room, but in a format that can be played at home. —description from publisher
