Done! After some internal debate, I ranked them based on a combination of which I felt were the best from a 'mystery' perspective, and those which I enjoyed most. Unfortuantely, given that Chapter 18 was not on the list, I was not able to rate the best mystery thus far. This makes me grievously sad with sorrow, and summing it all up with a latin phrase of prodigial wit & verve, I weep.
Seriously, though. Glad to hear things seem to be on the mend! :)
