Teacher Tom Riddle⁵

Location: Professor Tom Riddle's House

Time: 3 AM

You carefully lower yourself from the kitchen window, trying not to make a sound. You can't see anything, as the kitchen is dark, but you can see a faint light coming from the living room. You know someone is there because you hear a slight rustling of paper and the sound of someone drinking.

You carefully walk behind a wall and look into the room, only to see a desk lamp on a bar table with an empty brown sofa. On the table there's also an empty coffee cup and a pile of papers. You realize the person who should be in the room is gone. You look around for them when suddenly you feel the tip of a wand behind you, paralyzing you.

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

Please describe what you look like.
