My first ever entry into fanfiction, this was written in script format, which a fair number of people were using at the time, because I wasn't yet confident in my ability to write prose descriptions.

I think the comedy parts of this more or less hold up over time, though some of it is unnecessarily crude. The serious bits, not so much; the two villains (the killer, and the person who set him off) are rather cliche. Oh well, live and learn.
