Lolita by Vladimir Nabokov

By the time I reached Beardsley, in the course of the harrowing recapitulation I have now discussed at sufficient length, a complete image had formed in my mind; and through the-always risky-process of elimination I had reduced this image to the only concrete source that morbid cerebration and torpid memory could give it.

Except for the Rev. Rigor Mortis (as the girls called him), and an old gentleman who taught non-obligatory German and Latin, there were no regular male teachers at Beardsley School. But on two occasions an art instructor on the Beardsley College faculty had come over to show the schoolgirls magic lantern pictures of French castles and nineteenth-century paintings. I had wanted to attend those projections and talks, but Dolly, as was her wont, had asked me not to, period. I also remembered that Gaston had referred to that particular lecturer as a brilliant garçon; but that was all; memory refused to supply me with the name of the chateau-lover.
