Titles for the Mystery Prologue. Number 1

Yup.

The first one I've thought up was, "The Big Small World."
This is for the idea that the main character has stated in the prologue "The world we know is huge, I mean, massive. But the actual world we exist in, the circles we twirl in, the footsteps we make, the places we go, the city that we live in... All these are really quite small."
I really hope you use my title. Either one. If not, I will still read this book. It appears to be good work.
