Teacher Tom Riddle⁵

Location: Professor Tom Riddle's House

Time: 3 AM

You climb down carefully from the kitchen window, trying not to make a sound. You can't see anything since the kitchen is in darkness, but there is a faint light coming from the living room. You know someone is there upon hearing a slight sound of papers crumpling and the sound of someone drinking.

You walk carefully behind a wall and peek into the living room, only to see a desk lamp lit on a bar table with an empty brown sofa. On the table, there is also an empty cup that previously held coffee and a pile of papers. You realize that the person who should be in the room has gone. You look around searching for them when suddenly you feel the tip of a wand behind you, leaving you paralyzed.

"Move and I'll cast an Avada Kedavra." A husky voice with a British accent is heard behind you.

Please describe what you look like.
