33D STUDY. The room holds a table and a dead body.
On the table are a candlestick, a lead pipe, a dagger, a rope, a wrench, and a pale stain where a strange shaped metal object used to lie.
The body is wearing a black lab coat with a name tag labeled "Doctor". Buried in the spinal column is an odd piece of metal, a cylinder roundly tapered at one end.
The fireplace is actually a secret door, leading to Room 33G via a teleporter. It is activated by pulling on a torch bracket, the only one in the room.
