"All right, Gob." Billy says, turning to the small monster. "If Mr. Ashgrove gives you his lighter, do you promise not to eat it?"
"Yes!...Not Eat!"
"Now this would be a promise between friends Gob. You never break a promise between friends, it just not done."
"Promise!"
"Good. Mr. Ashgrove, give Gob your lighter and the wick. He can stay here and keep watch on it. Now Gob, If anything happens, you light that wick and follow it out of the library. And if nothing happens, we'll come back for you."
Gob nods his head in nervous affirmation.
"Great! Mr. Ashgrove, hand over your lighter and wick please."
