The air-conditioning in the luxury office in Bangkok was humming. Ruan Hong and his people were sitting in the booth on the east side, banging the table and smashing bowls. I walked over and knocked on the table and said that a box of 1982 lager beer cost 388,000 baht. He jumped up on the spot and shouted, who are you trying to fool me? Gao Jin stood beside me in a straight posture, his sleeves brushing against the edge of the bar. When the toe of my boot touched Ruan Hong's lapel, I glanced down - half an inch of the sheath of the knife on his waist was exposed.
