Twelve or fifteen?

How many chapters should my first Cozy Mystery be?

Yes, this question is like a ticky-tacky foul in basketball, more annoying than truly substantive. However, my wonky mind exists entirely in Ticky-Tacky Land, so it becomes rather an important query for a nut like me.

I’m at Chapter Ten of my Cozy. So, should I stretch it to fifteen or cut it short at twelve?… Or should I do whatever the darn well, I please? (This nut is leaning to option #3.)

Opinions?

Until tomorrow…
