I am not a good writer but I do have some suggestions (as a reader):
First of all, I have to say, I cannot really pick a title by the text given- maybe if I had the chance to read the full story- I'm sure it's great.
A short, catchy title- maybe one word that describes the main character, a word (or short phrase) that sums up the THEME of the story, or just the first name of the character, OR a word that is frequently repeated during the story.
The name of the character as the title- e.g. The strange case of [insert name here] << of course, that's inspired by some books...
The name of the character AND- e.g. [insert name here] and the [insert object here]
The PLACE setting of the story- e.g. Murder in [insert place name]
OK... I am out of ideas, gomen
As I said, I am all out of ideas (gomen again). I am not a proficient writer. Those are just some ideas to get you started.
