The grandfather clock strikes midnight as you enter Elijah's study. Your brother lies dead, your handkerchief in his hand. Footsteps approach. 'What have you done, Alexander?' Lady Margaret stands in the doorway, her eyes wide with horror.

{"user": "I quickly hide the handkerchief and pretend I just entered","char": "Richard bursts into the room. 'Father! What happened?' His gaze lingers on you. 'You... What are you doing here?' Lady Margaret appears behind him, her face pale at the sight of you near the body."}

{"user": "I examine the body for signs of struggle","char": "You notice a strange almond scent from the deceased's lips. On the table - a half-broken pen and spilled whiskey. Suddenly you hear a quiet rustle - someone was just behind the door and disappeared."}
