"What line?" replied Roth.
"That one, there!" I nodded my head in the direction of an empty area of wooden floor. It was quite dusty, as though the building had been abandoned for years.
"There isn't a line there. I'm puzzled. Should there be?"
"We're early. It's not there yet..."
We weren't, as it happens, all that early. As we watched a chalk line appeared and slowly sketched out an intricate shape on the floor.
"I agree," agreed Roth, "Hey, it's the outline of a body! Like at a crime scene!"
"Ex-police artist."
"Why can't we see him?"
"Ex. He's dead. The police don't often employ ghosts. I think they are prejudiced."
We watched for a while.
"Do you think the body really did have two heads and three arms?" enquired Roth.
"I think he drew the way he felt."
