They usually work in pairs, a talker and a lookout. The lookout never says a word, but was surreptitiously attentive of the surrounding. The talker had a silver tongue and a voice to rival Morgan Freeman and James Earl Jones. The man could sell brass knuckles to Ghandi. He could talk a turtle out of its shell. If he spoke in a coal mine, diamonds would tinkle from the ceiling. He buttered her up like a Sunday roll. She never had a chance.
