I was the bag man, there to stuff burlap sacks with body parts. We were in a dim alley behind a San Diego fish market. Conway Bowman's feet dangled over the edge of a Dumpster as he tossed tuna carcasses over the rim.

"Oh, bitchin'. Check these out,-¿ Bowman said as he slid to the ground and handed me two albacore bellies, the Dom Perignon of chum. We threw them in the sacks, nodded at two puzzled onlookers, and headed toward the Dana Landing Marina, where we would launch our chase for shortfin mako sharks on the fly.
