It seems like your ideas with the shoes went in the same direction, taking them as a symbol of death, even more, a symbol of a transitional stage between life and death. You both have a dead main character, who is not just dead but in the in-between, for both the shoes are part of the step from one world into the other (literally for Mandle's protagonist; in the form of a realisation for Baron's).
Baron: I'm not enterly sure what happened with Detective Brenner. It's clear she's dead and it's clear she hasn't realised this at the beginning of the story and that the shoes tip her of, not just to her death, but to who she is to some degree. But how did she die? How did Hal die? (If he actualy died - "gone" could, technically, also mean that he left) The two most likely scenarios are that she either shot herself or that Hal killed her, but there are a few other possibilities as well. It's not clear.
The story is very philosophical in nature, musing about life and death and the futility of existence and in this aspect it is very well done. I think it would work even better if we had known Brenner for a few scenes longer, maybe even one where she is still alive.
The revelation in the end could also be a bit stronger. Detective Brenner knows who she is (as the text is from her point of view and she is referenced by name), yet she can't make the connection to the Name Yulia Kosovich without seeing the name on her keyring? I do love the very last sentence though. I can't tell why, but it feels very strong.
Mandle: This story feels incomplete - which it is, as you said yourself. There are just too many loose ends for it to work the way it is. I'd love to read the full version, to see how it matches with the speculations and ideas that formed in my mind as to how the story would and should continue.
When re-reading, after reading your comment, I thought about ways that could turn this into a complete story without the need for a lot of re-writing, that is also not very time-consuming. I'll just put them here, mainly as a thought experiment:
- Remove the framing devise of the protagonist telling his story to someone. You necessarily need to come back to this to avoid a loose end, and we don't want to write more here for now.
- Remove all references to Jacob. It's impossible to resolve this plot thread in such a short story as long as you want to keep the general structure intact.
- Shift the protagonists personality slightly, to make him more of an egostic asshole. That's the part that needs the most rewriting, but we already have him attacking the Angel of Death, so it will fit with this part of the story
No brother to rescue and a generally unpleasent personality changes the tone of the ending, but turns it into a proper ending. The protagonist basically conquered death and starts a new "life" without a care in the world. This obviously changes the whole tone and feeling of the story, but it would make it into a complete one without a whole lot of re-writing.
The way the story is right now - I like the writing and the descriptions und the tone (more than I would in the edited version I suggest above) but there's just too much missing. It feels incomplete because it is and that makes it difficult judge. Normally, I would say there are loose ends (obviously) or the end feels rushed or somesuch, but that is all due to it not being finished. I'd say it's worth working on and completing it, though.
Baron wins for me this round.
