Sergius smiled again. He was getting somewhere, and he let the hand holding the envelope pull back slightly, just out of Slater's grip. "I would like a list of your clients, Mr. Slater. Supply me with information concerning patronage of any of your establishments. Names, and the frequency of which they visit. That is simply all. Of course, for your help as well as this..." He said, lifting the hand again, and opening up the envelope carefully, taking out the folded sheets of paper, unfolding them while his eyes remain on Slater. "I would furnish you with funds for your trouble. Say... one hundred of your British pounds?"
He stops again, glancing over the list of names, now unfolded in his hand. "Are you interested, Mr Slater?"
