Herbert’s next stop were charts of the shipping lanes in that region. He got a list of tankers, fishing vessels, ocean liners, and pleasure boats that had been through the area in the past seventy-two hours. When he got the names, he switched to his generic BOB4HIRE screen name. Claiming to be an insurance investigator, he E-mailed the various shipping companies and charterhouses. He asked if any of them had received a report of an explosion in the Celebes Sea. While he waited for the answers, he contacted the National Reconnaissance Office. He asked for an ID listing of all the ships that had accessed global positioning data around the time of the explosion. That information was supposed to be confidential, stored in coded files known only to the vessels and the satellites. However, the NRO had access to the satellite databases, thanks to the Confidential Reconnaissance and Code Satellite. CRACS was one of a new generation of satellites that spied on other satellites. Using sophisticated background radiation detectors, it read incoming and outgoing satellite pulses that momentarily blotted out the cosmic radiation. CRACS ended up with a silhouette of the communication from earth. The satellite was able to translate the pulses into numbers. That, in turn, gave the NRO the code words used by the earth-based planes or ships to contact the satellite.

What Herbert was looking for was an inconsistency. He was hoping to find a vessel that might have been close enough to hear the sampan explosion but did not report it. If he found that, chances were good it was the ship the pirates had tried to waylay.

The data came in slowly over the next several hours. During that time Herbert reveled in the relative comfort and privacy of his little section of the airplane. He was facing the starboard side of the aircraft, and there was a small window to his right. He leaned forward and looked down. The view inspired him. Not because it was a big, beautiful ocean but because it reminded him how people had fought and suffered and perished to explore it. Nothing came without hard work and sacrifice. That fact kept Bob Herbert from slipping into bitterness for what his own public service had cost him.
