Claudia takes the handset. "Doctor, what could cause a

There is a pause. "The medical term is dementia,"
the voice comes back. "Deteriorated mentality. Something is preventing

"Something -- such as what?"
The doctor's voice is calm. "Something that can cross
the blood-brain barrier." Pause. "First we must consider metal poisoning..."
The voice fades into static.
