A huge furry creature bounded through the door with his lunch tray. It was grinning like a maniac.
Prostetnic Vogon Jeltz was delighted. He knew that when a Dentrassi looked that pleased with itself there was something going on somewhere on the ship that he could get very angry indeed about.
Ford and Arthur stared about them.
"Well, what do you think?" said Ford.
"It's a bit squalid, isn't it?"
Ford frowned at the grubby mattress, unwashed cups and unidentifiable bits of smelly alien underwear that lay around the cramped cabin.
"Well, this is a working ship, you see," said Ford. "These are the Dentrassi sleeping quarters."
"I thought you said they were called Vogons or something."
"Yes," said Ford, "the Vogons run the ship, the Dentrassis are the cooks, they let us on board."
"I'm confused," said Arthur.
"Here, have a look at this," said Ford. He sat down on one of the mattresses and rummaged about in his satchel. Arthur prodded the mattress nervously and then sat on it himself: in fact he had very little to be nervous about, because all mattresses grown in the swamps of Squornshellous Zeta are very thoroughly killed and dried before being put to service.
Ford handed the book to Arthur.
"What is it?" asked Arthur.
