And the next thing that happened after that was that the Heart of Gold
continued on its way perfectly normally with a rather fetchingly redesigned
interior. It was somewhat larger, and done out in delicate pastel shades of
green and blue. In the centre a spiral staircase, leading nowhere in
particular, stood in a spray of ferns and yellow flowers and next to it a stone
sundial pedestal housed the main computer terminal. Cunningly deployed lighting
and mirrors created the illusion of standing in a conservatory overlooking a
wide stretch of exquisitely manicured garden. Around the periphery of the
conservatory area stood marble-topped tables on intricately beautiful
wrought-iron legs. As you gazed into the polished surface of the marble the
vague forms of instruments became visible, and as you touched them the
instruments materialized instantly under your hands. Looked at from the correct
angles the mirrors appeared to reflect all the required data readouts, though
it was far from clear where they were reflected from. It was in fact
sensationally beautiful.

Relaxing in a wickerwork sun chair, Zaphod Beeblebrox said, ``What the hell
happened?''

``Well I was just saying,'' said Arthur lounging by a small fish pool,
``there's this Improbability Drive switch over here ...'' he waved at where it
had been. There was a potted plant there now.

``But where are we?'' said Ford who was sitting on the spiral staircase, a
nicely chilled Pan Galactic Gargle Blaster in his hand.

``Exactly where we were, I think ...'' said Trillian, as all about them the
mirrors showed them an image of the blighted landscape of Magrathea which still
scooted along beneath them.

Zaphod leapt out of his seat.

``Then what's happened to the missiles?'' he said.

A new and astounding image appeared in the mirrors.

``They would appear,'' said Ford doubtfully, ``to have turned into a bowl of
petunias and a very surprised looking whale ...''

``At an Improbability Factor,'' cut in Eddie, who hadn't changed a bit, ``of
eight million seven hundred and sixty-seven thousand one hundred and
twenty-eight to one against.''

Zaphod stared at Arthur.

``Did you think of that, Earthman?'' he demanded.

``Well,'' said Arthur, ``all I did was ...''

``That's very good thinking you know. Turn on the Improbability Drive for a
second without first activating the proofing screens. Hey kid you just saved
our lives, you know that?''

``Oh,'' said Arthur, ``well, it was nothing really ...''

``Was it?'' said Zaphod. ``Oh well, forget it then. OK, computer, take us in to
land.''

``But ...''

``I said forget it.''
