This is a line from "Der Vorleser" by Bernhard Schlink:

Eines frühen Abends im Februar hörte ich eine Amsel singen.

One early evening in February I heard a blackbird singing.

eines (masc+genitive+singular)

frühen (masc+genetive+singular)

Abends(m) (genitive+singular)

Why is the eines in the genitive? "One" is not belonging to anything.

Why isn't it like this:

einer frühen Abends

This is a sentence from one of my textbooks:

einer meiner Handschuhe fehlt

one of my gloves is missing

The "einer" in this sentence in masculine and nominative.

--- EDIT ---

Thanks for the help. I was confusing the pronoun "einer" meaning "one of" with the article "ein" meaning "a" or "one".

    Please, be more careful, unless you don't care about careless answers. Begin with the book title; it is Der Vorleser. – Björn Friedrich Apr 27 '19 at 13:26

    "einer frühen Abends" is totally wrong. Should be eines frühen Abends. – πάντα ῥεῖ Apr 27 '19 at 14:09
  • In “einer meiner Handschuhe”, “einer” just means “one”, The “of” is expressed by the genitive in “meiner Handschuhe”. – Carsten S Apr 27 '19 at 20:03
