Two days ago, the crew of a Chilean fishing vessel saw something fall from the sky. They were into the Humboldt current, watching the approach of a fast-moving weather front, when they heard a roar like a huge turbine in the sky. The rain swept over them, and through the sheets coming down through the clouds they saw a vision that at times took on material definition and flickered with an electricty of its own. Captain Cromartie has a pretty good idea what''s down in those cold waters -- he''s pretty sure he''s fishing for Predators. But knowing what you''re fishing for and knowing how to catch it are two totally different things.
