A modern tale

posted by Arkham on October 29th, 2008


It was a dark and stormy night. Somewhere in the distance a dog howled. A shiny object caught Alice’s eye. A diamond cufflink! Only one person in the household could afford diamond cufflinks!

So it was the butler, after all! Alice had to warn Bob. But how could she get a message to him without alerting the butler? If she phoned Bob, the butler might listen on an extension. If she sent a carrier pigeon out the window with the message taped to its foot, how would Bob know if it was Alice that was sending the message and not Trudy attempting to frame the butler because she spurned her advances?

That’s what this book is about. Not much about character development for Alice and Bob, we’re afraid; nor do we really get to know the butler. But we do discuss how to communicate securely over an insecure medium…
