А этот молоденький, маленький, в очках... Митя вот только фамилию его позабыл, но он знает и его, видел: это следователь, судебный следователь, "из Правоведения", недавно приехал.
And that small young man in spectacles.... Mitya forgot his surname though he knew him, had seen him: he was the "investigating lawyer," from the "school of jurisprudence," who had only lately come to the town.
