A guest has been murdered in the mansion. You are the detective. Somewhere in these rooms are a hidden magnifying glass, the bloodstains that mark the scene, and the bloodied weapon.

Roam the halls, examine clues, and question the guests — but tread carefully. One room's floor is stained where it happened; a guest may give it away by staring at the floor. Ask too many questions and the killer grows suspicious. Dawdle too long and you become the next victim.

Name the murderer, the weapon, and the room to close the case.
