Is there going to be more? If you wouldn't mind, as you did ask for some advice in the title, I'd like to offer my modest suggestions ^.^ I felt a little lost after finishing your piece, while it was intriguing and catching, pulling the reader in well, I think it lacked information. You ended with a final statement that the crime was one of passion, and a crime of passion usually involves jealous lovers and murder, does it not? Maybe I'm wrong, and this is only a suggestion, but perhaps you could better the message of your story by adding a flashback or some fervent crazy thoughts of your character. This, I think, would help the reader understand what was about to take place. ^.^ Great start, though, and I'd love to read more!
