question:  Why couldn't most people tell Matilda where Haron lived?
context: She had been known to say that there are over a billion men in the world, a goodly percentage of whom are eligible bachelors, and that the right one would come along simply because she had been waiting for him. She would read them carefully and then read them again, looking for the masculine names which, through a system known only to Matilda, had an affinity to her own. The name—Haron Gorka: its oddness was somehow beautiful to Matilda. Cedar Falls was a small town not fifty miles from her home, and she'd get there a hop, skip, and jump ahead of her competitors, simply by arriving in person instead of writing a letter. Matilda knew he would peer over his glasses and answer questions grudgingly. Matilda asked him where she could find Haron Gorka. First place, I don't know any Haron Gorka—" Matilda kept the alarm from creeping into her voice. Matilda did, only they didn't know any Haron Gorka, either. It turned out that no one did: Matilda tried the general store, the fire department, the city hall, the high school, all three Cedar Falls gas stations, the livery stable, and half a dozen private dwellings at random. As far us the gentry of Cedar Falls was concerned, Haron Gorka did not exist. If she could not find Haron Gorka, that was one thing; but she knew that she'd rather not return home and face the widow Penshaws, at least not for a while yet. Certainly a man as well-educated as Haron Gorka would be an avid reader, and unless he had a permanent residence here in Cedar Palls, one couldn't expect that he'd have his own library with him. This being the case, a third-rate collection of books was far better than no collection at all, and perhaps the librarian would know Mr. Haron Gorka.
output:  he hadn't been in Cedar Falls for long
options:  he was a very secretive person  he hadn't been in Cedar Falls for long  he wanted to hide from the interested women  he used another name when out in public
