There are no real spoilers here by the way, I'm still not a hundred percent sure whodunit (oh I do amuse myself sometimes!) but the images do give the victim away if you look carefully. Consider it fair warning.
I have 8 main characters, including the victim, plus one or two minor ones, and each main character has his or her own character development page in my NaNo file... The characters are slowly starting to round out, but it takes a staggering amount of thought to remain consistent-ish. Just reminds me how incredibly complicated real people are! Anyhow, real or not I hope that these 8 are enough to keep me going for 50000 words!
