Narrator and point of view

The short story “Tobias” is a third-person narration. The narrator is outside the plot and conveys most of the events from the perspective of an outside observer, which implies limited knowledge:

“ ‘Tobias,’ she said, coming in. She took off her nurse’s shoes and lit a cigarette. ‘Any luck?’
‘I haven’t been out all day,’ he said, then shrugged and smiled.” (p. 1, ll. 11-12)

However, the narrator also uses Tobias’ perspective from time to time. He knows what Tobias is thinking and feeling, but this does not apply to Miriam as well: “…Tobias basked in the sun, refusing to think. (…) By October she had lost her characteristic smile, and Tobias knew he would lose his position as her lover within two weeks.” (p. 1, ll. 7-10)
