shoulder was pressed against the jamb of the hatchway in which he’d seen the smoker. He crouched down, then undogged the hatch a half inch and inserted the flexicam. The lens revealed a red-lit passageway, ten feet long, and ending in a split ladder way, one going up and one going down.
According to Grimsdottir, the
Fisher withdrew the flexicam, then drew his pistol, opened the hatch halfway, stepped through, and pulled it shut behind him. He crouched for a full minute, listening and watching, until he was sure he was alone, then holstered the pistol.
He tapped the OPSAT’s touch screen and called up the
He crept to the ladder and peered down, belowdecks, and saw nothing, so he mounted the ladder and climbed upward until his head was even with the deck above. Another passageway. This one, which had no direct access to the weather decks and therefore had no chance of emitting light other ships might mistake for navigation lights, was lit not by red lamps but by wall sconces, which cast pools of dim light on the overhead and deck.
On cat’s feet Fisher climbed the remaining few steps, then started down the passage. He counted doors as he went. There were ten, one for each crew member and two spares. The doors were evenly split down the port and starboard bulkheads, five to each side, with an eleventh door — a janitor’s closet — in the middle of the port bulkhead. As Fisher had feared, there were no name placards on the bulkhead, so finding which room held Stewart would take more time than he had. It was time to test his ruse.
He walked to the end of the passage and stopped before the last door, where he crouched. From a pouch on his calf he withdrew a thumb-size cylinder of compressed air topped with an articulated and long-stemmed nozzle like those found on cans of WD-40.
Inside, suspended within the compressed air, were thousands of RFID (radio frequency identification) chips, each the size of a grain of sand — essentially RFID powder. Miracles of miniaturization, RFID chips had initially been designed for loss prevention in U.S. retail stores. Each product gets an adhesive tag into which RFID powder has been embedded and each chip, or grain, is equipped with 128-bit ROM, or read-only memory, onto which a unique identification number has been engraved by an electron beam. When a chip, or a sprinkling of chips, comes within range of a detector, the ID number is read and verified as purchased or not yet purchased.
For Fisher’s purposes, the good folks at DARPA had taken the RFID powder concept one step further, first by coating each chip’s surface with a silicate that acted much like a cocklebur that attached itself to anything and everything, and second by affixing to each grain an external antenna — a tiny ribbon of wire half an inch long and barely the width of a human hair — that extended the chip’s transmission range to twenty feet.
As usual, of course, Fisher hadn’t liked DARPA’s official name for the RFID powder, which contained so many letters and numbers it looked like a calculus equation gone wrong, and had renamed it Voodoo Dust.
He pointed the canister at the deck before the door and pressed the nozzle. He heard a faint
Into the SVT, he said, “Paint job done. Shake the tree.”
“Roger,” Sandy replied from the Osprey. “On your button four. Ten seconds.”
Fisher tapped the OPSAT’s screen, calling up the communications panel, then switched his earpiece to the indicated channel. For five seconds there was nothing but static, and then Sandy’s voice: “Cargo vessel
Silence.
“I say again, cargo vessel
“Yes,
“
Ten seconds passed and then, “Roger,
There was in fact a Canadian Coast Guard patrol ship named
“
“Uh…
“
“Understood,
Fisher snaked the flexicam out the louvered panel at the bottom of the door and switched to a fish-eye view so he could see both ends of the corridor.
Two minutes passed without any activity. Then he heard it: a pair of feet pounding down a ladder somewhere forward of him and above. The pounding got louder until the footsteps entered the passage outside Fisher’s door. A man appeared at the forward end of the passage. Fisher tapped RECORD on the OPSAT’s screen, then switched the flexicam’s lens to regular view and swiveled it to focus on the man, who was now striding down the passage. The man stopped at the fourth door on the starboard side, slipped a key into the lock, then pushed through the door. Fisher heard muffled voices, then a shout, some scuffling. The figure reappeared, now with a gun in his right hand and the bunched collar of Calvin Stewart in the other. Stewart’s hands were duct-taped before him. His captor half dragged, half marched Stewart down the passageway, and then they disappeared from view down the ladder.
Fisher withdrew the flexicam and studied the OPSAT’s screen. Most of the blue RFID dots remained in the passageway, but four of them — about four hundred chips — had done their job and clung to the shoes of Stewart’s captor. The dots were moving aft and down.
He rewound the flexicam’s video feed to where Stewart’s captor entered the passageway, then manipulated the timeline bar, forwarding and rewinding until he had a clear, well-lighted view of the man’s face.
“Well, this is unexpected,” Fisher whispered.
The face on his screen was Asian — Korean, if he wasn’t mistaken.
