"He could," Rick agreed. "But why would he want to reach the mine area?"
"Not to sell Frostola. That's for sure."
"Uh-uh. My guess is he has to reset the Blue Ghost."
"Reset it?"
"Sure. Think about it. The projector can't go on operating forever when a clock reaches nine, can it? It must need servicing and resetting."
"And loading with methyl chloride to squirt at us?"
"Too true." Rick had wondered about that. "But how does the chemical squirter work? Where is it? The projector must be close to the Blue Ghost, if the chemical came from the same place."
Scotty laughed. "You don't discourage easily, do you? We tried to find a projector beam the other night, remember? What did we get for it? A squirt in the face. No projector, no nothing."
"There has to be a projector, or an imagemaker of some kind," Rick insisted, "unless you're admitting the ghost is real."
"Where would it be located?"
