Early in their career the men learned how to mingle with harbor traffic to select their prey, how to track them until dark, and how to come alongside swiftly and quietly. They learned how to prowl the shipping lanes with their backs to the setting sun so that they would not be seen. Former police sergeant Koh Yu kept both a 500-channel scanner and a world band receiver on board to monitor restricted police and military communications. He had stolen them before resigning from the Special Operations Command of the Singapore Police Force. After sampling all kinds of ships, they focused on yachts and fishing charters. The take was usually good, and resistance was limited to indignant words. Since most of those words were English, Lee didn’t understand what was being said. Among them, only the unflappable Koh spoke English. And Koh did not care what was being said. None of the men felt remorse about the work they did. On land, the large took advantage of the small. The fat had their way with the lean. At sea, the sharks ate the tuna. Lee Tong had tried both lives.

He preferred being a shark.

They began by waylaying small pleasure boats, tour ships, and party vessels out of Hong Kong and Taipei. The men didn’t even have to board the ships to rob them. They came alongside and pressed plastic explosives low on the hull. The soft, explosive patties were homemade from concussion-ignited mercuric fulminate—a mixture of mercury, alcohol, and nitric acid—paraffin, and linseed oil to keep the wax pliant. That was a contribution of eight-fingered Clark Shunga, a former demolitions man for the lumber industry. Trees that were too difficult to cut down were blasted down. When he lost two fingers to a faulty detonator cap, he was fired with meager compensation. The Woo See Lumber Company was afraid that he would kill someone by mishandling explosives. He showed them that he could still play the guitar, but they were unimpressed. Clark put all of his severance pay—fifty dollars—toward the sampan.
