Dan Groat
“I can’t tell you what’s in all of God’s plans, but I do know part of them. He empowers you with reason and will. Those are your strengths. That’s what gives you the chance to be great in his sight. He gave you a mind and codes to live by so you could be in charge of your own actions.”
Dan Groat, Monarchs and Mendicants

Tom Pollock
“A Caesar shift is about the simplest code in the world – perfect for the Roman emperor who’s long on secrets but short on time.
To make one, you just write out the alphabet, A to Z, then pick a secret phrase… and write it out underneath the first few letters of your alphabet, dropping any repeated letters…”
Tom Pollock, This Story Is a Lie
