IF cdoconn is actually a mime, I doubt they would have the strength to cave in the ringmaster's head. However, something heavy dropped from above...say, by an acrobat...could have killed our beloved leader.
As for me, I don't need to worry about killing anyone over some financial worries. Even if our circus goes under, my skills are such that I can always find work. But I'll miss that ringleader, really was a great boss.
So if we have 23 circus members and perhaps 4-5 wolves, what of the people who haven't spoken? Are they too busy to check the thread or too worried about incriminating themselves? And speaking of chaos, I think Dr.S seems suspiciously worried about appearing logical and non-chaotic. Perhaps to throw us off the trail?
