Hehe. It's so shameful :) Congrats to winner and thanks Slaugh for his another mystery GA. As well as to allowed me to embarrass much myself :)
Next time I should be more careful when posting via phone.

Thanks for the contest and for the final reveal of all that data!

You really put a ton of work into making this fly! Big thanks and +100!

Just busting on ya in fun! I hope it came across that way! Good showing, mate!

Yay! :P

Well, 4 mistakes in 55 eliminations... That's about 93% correct, I think. I think I can be satisfied with myself. :)

BTW, if anybody cares, here's my private WIP elimination list. Yes, I've eliminated Flail mistakenly. :P

PS: Thanks again to _Slaugh_ for the exhaustive statistics. :)

Awesome! Congrats all around to the investigative team.

Things will be much more peaceful around the GOG Manor with this case in the books. Or at the very least, a number of us will have a lot more free time on our hands ;)
