I knelt to examine the floor, and there it was, in tiny writing, quite fresh it seemed, scratched with a pin or maybe just a fingernail, in the corner where the darkest shadow fell: Nolite te bastardes carborundorum.

I didn’t know what it meant, or even what language it was in. I thought it might be Latin, but I didn’t know any Latin. Still, it was a message, and it was in writing, forbidden by that very fact, and it hadn’t yet been discovered. Except by me, for whom it was intended. It was intended for whoever came next.
