My mind was nagging me about this title, so I went to dictionary.com and looked up "nocturne." Here's what it returned:
1. A painting of a night scene.
2. An instrumental composition of a pensive, dreamy mood, especially one for the piano.
My, my, my, this fits so well that I suspect Shayne is either an artist or a musician, aside from being a highly skilled writer. This is a sad, lonely, thoughtful, and dramatic piece. I sure hope there's a final coda already planned, because if this becomes an orphan story after this buildup, I may just break down and cry.
