In my newsletter, which you can sign up for here, I offered a prize (to be determined later and not of any huge value) to the first person to identify that lurking figure who, well, lurks around the library in earlier strips. I’m opening that to everyone who reads this. It’s a personage pretty much everyone has heard of, and the library theme of this comic may help you guess the medium from whence this character originates. Just contact me if you think you know. And if you do get it right, don’t tell anyone else for a few weeks.
Update: Wow, someone got it! So contest over. I have a prize idea, I’ll just have to speak to the lucky winner, someone I actually know.
