" I came to a payphone and used the number Tatsu had given me. He picked up on the first ring. “Okay to talk?” I asked him. “Yes.” “Our man trains for his fights. Not at a regular dojo.” “I expect that is correct.” “Do you have information about where?” “Nothing beyond what is in the envelope.” “Okay. Here’s what we’re looking for. A small place. A hundred square meters, something like that. Not in an upscale neighborhood, but not too far downscale, either. Discreet. No advertising. Tough clientele. Organized crime, biker types, enforcers. People with police records. Histories of violence. You ever hear of a place like that?” “I haven’t. But I know where to check.” “How long?” “A day. Maybe less.” “Put whatever you find on the secure site. Page me when it’s done.” “I will.” I hung up. "
