As they approached the ridge of higher ground they became aware that it seemed to be circular — a crater about a hundred and fifty yards wide. Round the outside of the crater the sloping ground was spattered with black and red lumps. They stopped and looked at a piece. It was wet. It was rubbery.
With horror they suddenly realized that it was fresh whalemeat.
At the top of the crater's lip they met Zaphod.
"Look," he said, pointing into the crater.
In the centre lay the exploded carcass of a lonely sperm whale that hadn't lived long enough to be disappointed with its lot. The silence was only disturbed by the slight involuntary spasms of Trillian's throat.
"I suppose there's no point in trying to bury it?" murmured Arthur, and then wished he hadn't.
"Come," said Zaphod and started back down into the crater.
"What, down there?" said Trillian with severe distaste.
"Yeah," said Zaphod, "come on, I've got something to show you."
"We can see it," said Trillian.
"Not that," said Zaphod, "something else. Come on."
They all hesitated.
"Come on," insisted Zaphod, "I've found a way in."
"In?" said Arthur in horror.
"Into the interior of the planet! An underground passage. The force of the whale's impact cracked it open, and that's where we have to go. Where no man has trod these five million years, into the very depths of time itself ..."
Marvin started his ironical humming again.
Zaphod hit him and he shut up.
