"We suspect a respected professor of being involved in a horrific deed, yet the only proof we have is anecdotal and circumstantial and none of us have any authority to do anything within legal reason."

"We're not a lynch happy vigilance committee, so we need more than righteous indignation, no matter how well place," continues Josh. "But, if we are caught in his house, we will be in the wrong, in the opinions of the law, unless we find something first."
"Is there anyone that we can all agree is trustworthy," asks Josh. "Someone we can tell that we are looking into this, so as to cover our own tails?"
