This is an interesting book to translate to English. Glebsky is trying to determine the gender of Brune for the half of the book and this involves trying to make him/her to talk about oneself in the past. In Russian verbs are inflected with gender only in the past tense so somebody speaking about oneself in the past will have to inflect verbs with one's own gender but there is no gender specific grammar for the present and future.
Did they do something clever in the translation or just dropped this plot line?
