You make sure you are well hidden in the bushes and then wait for Victor and the mystery man to arrive.
Victor arrives first and stands around for a few minuets, occasionaly glancing at his watch. Eventually a darkly dressed figure appears from the bushes. His face is covered by a mask, but his voice sounds familiar.
"Are you prepared?" Victor asks the man.
"Yes" he responds, "I have all the required information right here in my costume," he says as he pats the side of his chest. "By the end of the night they will gladly sign over everything."
"Excellent," Victor says,"but don't let anyone onto who you really are. It could ruin everything."
"Don't worry, I'll be discreet at during the party. Nobody will notice me. But don't foget our deal. Part of that fortune is rightly mine."
"Don't worry, you'll get more than your fair share," Victor says. "Now get to work."
Victor then enters the Mansion, the mysterious figure vanishes into the night.
