The Slaying of the Boredom Monsters

Half term, day two - and I'm bored already. That's probably a good sign, means I want to get back to school and do more teaching. Anyhow, to kill some time, I've been designing some new puzzles. I'll fire them up here over the next few days... if I remember, of course.

Here's your first one! First correct solve wins a pint! You can give me your answer (do) in the comments, by email (idlemichael@gmail.com), or harrassment in #perplexorum on IRC.



Good luck - I think it's a stinker!
