With buckets of seawater, hauled up on a rope, they sluiced the steel floor of the bridge until it was no longer bloody. Learning their way around the vessel, they found scrub brushes and cleaning supplies and gave the place a more thorough washing down, swabbing blood splashes and fingerprints away from some of the bridge’s vertical surfaces. Marlon pulled the ruined radio off its bracket and threw it into the sea, trailing its bloody microphone.
The user interface of the GPS was anything but intuitive, but Marlon figured out how to zoom and pan its tiny map. Standing around it in the dark, they began to get a sense of where they had been—for the GPS displayed the boat’s past track—and where they were going. It seemed that, for the first hour of their voyage, Mohammed had steered them generally south along the coast, then changed to an easterly heading, making directly for Taiwan at a speed of something like ten knots. This had brought them to a point about thirty nautical miles off the Chinese coast, which was where the confrontation and shooting had taken place.
At that point, Marlon had dropped the vessel’s speed to more like five knots. This was not the absolute slowest they could go, but if they went any slower they lost all sense that they were making forward progress, and the boat seemed to wallow and wander (an impression that could be confirmed by zooming in on the track and observing the way it staggered across the screen). The rudder, it seemed, was not capable of doing its job unless water was flowing across it with at least some minimum speed.
Marlon told Csongor about what Batu had said regarding the fuel gauge, or lack thereof, and so Csongor went down to the engine room and spent a while figuring out how the diesels worked, eventually identifying the fuel line and the pump that fed it. From this, plumbing led back through a bulkhead to a space mostly occupied by a pair of cylindrical tanks of impressive and reassuring size, each rather more than a meter in diameter and perhaps three meters long. Each had a fill pipe welded into its top. Csongor traced those up to a pair of fittings on the deck, which he guessed they would use whenever they pulled up to the nautical equivalent of a gas station. Shining his flashlight around that area, working out slowly in concentric circles, he finally found where they kept the dipstick: a piece of (inevitably) bamboo secured under the gunwale with bungee cords, ruled with felt-tip scribe marks and (to him) cryptic annotations. He called Yuxia down to help him interpret the marks, and then they opened one of the fuel fill hatches and shoved the bamboo pole down into it. Then he began pulling it out in a hand-over-hand movement, praying that he would feel cold wet diesel fuel on his palms. This did not happen, however, until the last few inches of the stick emerged. Yuxia read the nearest number marked on the pole. This meant nothing since they had no idea how quickly the diesels consumed fuel. But there was no ignoring the fact that it was the last number on the stick. “We just have to be scientific about this,” Csongor said, and he marked the exact location of the fuel level and noted the time.
They then repeated the experiment with the other tank and found that it was completely dry. Csongor went down and fiddled with the valves and confirmed his suspicion that the empty tank had simply been disconnected from the system; the jihadists had only used the one tank, and they hadn’t bothered to put more than a little bit of fuel in it, since all they ever did was putter around the harbor at the island.
Yuxia went back up to the bridge to keep Marlon company and make sure he didn’t fall asleep on his feet, and Csongor devoted more time to sorting through the hold’s contents. It did not take a Sherlock Holmes to read the recent history of this boat. It had been owned, and used hard, for many years by actual fishermen who had accumulated the sorts of gear and supplies one would expect: nets, lines, stackable plastic trays, polyethylene cutting boards, cutlery, whetstones, all manner of tools, paint, lubricants, solvents, and the like. As sustenance on longer voyages they had also laid in white plastic drums of what he took to be potable water, and sacks of rice, and a few other bulk food items such as soy sauce and cooking oil.
Then, at some point, the boat had been acquired by the jihadists, who had turned it into a floating arsenal: probably not enough to run a war, or even an insurrection, but plenty if the only goal was to blow up a building or plan a Mumbai-style shooting spree. So there was a pallet carrying a black steel drum of what Csongor guessed, by smell, to be fuel oil, and another carrying heavy woven-plastic sacks of white powder labeled as FERTILIZER: ammonium nitrate, presumably. Those two ingredients, mixed together, would make a high explosive that, as Csongor knew from reading the newspapers, could be detonated if one had some blasting caps handy. Csongor had no idea what a blasting cap even looked like, but he soon enough found out, as a carton of them had been helpfully stored on a shelf next to a translucent plastic box filled with phones, all of the same make and model.
