By a curious coincidence, None at all is exactly how much suspicion the ape-descendant Arthur Dent had that one of his closest friends was not descended from an ape, but was in fact from a small planet in the vicinity of Betelgeuse and not from Guildford as he usually claimed.
Arthur Dent had never, ever suspected this.
This friend of his had first arrived on the planet some fifteen Earth years previously, and he had worked hard to blend himself into Earth society — with, it must be said, some success. For instance he had spent those fifteen years pretending to be an out of work actor, which was plausible enough.
He had made one careless blunder though, because he had skimped a bit on his preparatory research. The information he had gathered had led him to choose the name “Ford Prefect” as being nicely inconspicuous.
He was not conspicuously tall, his features were striking but not conspicuously handsome. His hair was wiry and gingerish and brushed backwards from the temples. His skin seemed to be pulled backwards from the nose. There was something very slightly odd about him, but it was difficult to say what it was. Perhaps it was that his eyes didn’t blink often enough and when you talked to him for any length of time your eyes began involuntarily to water on his behalf. Perhaps it was that he smiled slightly too broadly and gave people the unnerving impression that he was about to go for their neck.
He struck most of the friends he had made on Earth as an eccentric, but a harmless one — an unruly boozer with some oddish habits. For instance he would often gatecrash university parties, get badly drunk and start making fun of any astrophysicist he could find till he got thrown out.
Sometimes he would get seized with oddly distracted moods and stare into the sky as if hypnotized until someone asked him what he was doing. Then he would start guiltily for a moment, relax and grin.
“Oh, just looking for flying saucers,” he would joke and everyone would laugh and ask him what sort of flying saucers he was looking for.
“Green ones!” he would reply with a wicked grin, laugh wildly for a moment and then suddenly lunge for the nearest bar and buy an enormous round of drinks.
Evenings like this usually ended badly. Ford would get out of his skull on whisky, huddle into a corner with someone and explain in slurred phrases that honestly the colour of the flying saucers didn’t matter that much really.
Thereafter, staggering semi-paralytic down the night streets he would often ask passing policemen if they knew the way to Betelgeuse. The policemen would usually say something like, “Don’t you think it’s about time you went off home sir?”
“I’m trying to baby, I’m trying to,” is what Ford invariably replied on these occasions.
In fact what he was really looking out for when he stared distractedly into the night sky was any kind of flying saucer at all. The reason he said green was that green was the traditional space livery of the Betelgeuse trading scouts.
Ford Prefect was desperate that any flying saucer at all would arrive soon because fifteen years was a long time to get stranded anywhere, particularly somewhere as mindboggingly dull as the Earth.
