...The prison rose out of the cornfields, a concrete and steel monstrosity about as likely in this serene setting as an elephant in an igloo. The sentry couldn't help but smile at the thought. With no one else to amuse him, to distract him, to help push his days contentedly forward, he often amused himself in such ways.
...'I've done my work too well,' he thought. 'Opportunities to spill blood are so rare these days.'
This prison sentry is unlike any other. You don't want to cross him. Better that you should remain in your cell, follow the rules, and never get on his bad side.
Transgression comes at far too high a price.
