"You want to just soak them for two hours longer than any other beans in the world.

Before he could utter a cry, Quest's left hand was over his mouth and the cold muzzle of an automatic pistol was pressed to his ribs.

The pistol pressed a little further into his side.
"Upstairs," Quest repeated firmly.

"If you utter a cry I shall shoot you." Craig turned slowly round and obeyed.
