I can take absolutely zero credit for the title pun— either of them. The idea of a serial killer that kills serial stories, as well as a Character Assassin, is taken from the wonderfully metafictional Thursday Next series by Jasper Fforde— well, wonderful until Book 7. Then it gets weird.
I came up with this, from concept to posting, in less than three hours, and it probably shows— there's not much 'mystery' in this 'murder mystery'. The last time I coldposted an SCP, it went over as well as a greased-up tire in San Francisco— it went downhill fast.
Hopefully you'll enjoy it. Happy contesting, y'all.
