“Thank you,” Susan said shyly. “There’s still a lot more work to go. Years, maybe. I don’t know. A tiny sample in a test tube is a long way off from containing an oil spill.”

“Run your ideas to ground, is all I can say. Go wherever they take you, and for as long as you need.”

From someone other than Geoffrey Merrick that would have sounded trite but he spoke it with sincerity and conviction.

Susan met his eye for the first time since he’d entered the laboratory. “Thank you…Geoff. That means a lot.”

“And who knows. After we patented our sulpher scrubbers, I became a pariah to the environmental movement because they claimed my invention didn’t do enough to stop pollution. Maybe you can finally salvage my reputation.” He left with a smile.

After he’d gone Susan returned to her beakers and test tubes. Wearing protective gloves she took the one filled with her genetically modified diatoms and slowly tilted it to the side again. Ten minutes had elapsed since she’d last handled it and this time the water sample at its bottom clung to the glass as though it were glue; and only after inverting the hot beaker completely did it start to ooze downward, as slowly as chilled molasses.

Susan thought about the dying otters and seabirds she’d seen as a child and redoubled her work.

THE CONGO RIVER

SOUTH OF MATADI

THEjungle would eventually swallow the abandoned plantation and the three-hundred-foot wooden pier built along the river. The main house a mile inland had already succumbed to the effects of rot and encroaching vegetation, and it was only a matter of time before the dock was swept away and the metal warehouse nearby collapsed. Its roof sagged like a swaybacked horse, and its corrugated skin was scaled with rust and flecked paint. It was a haunted, forlorn place that even the soft milky glow of a three-quarter moon couldn’t liven.

A large freighter was nudging closer to the pier, dwarfing even the massive warehouse. With her bow pointed downstream and her engines in reverse, the water under her fantail frothed as she fought the current to stay on station. It was a delicate balance to maintain her position, especially considering the Congo’s notorious back-currents and eddies.

With a walkie-talkie held to his lips, and his other arm flailing theatrically, the captain paced the starboard wing bridge and yelled at the helmsman and engineer to make corrections. The throttles were moved in fractional increments to keep the 560-foot vessel exactly where he wanted.

A group of men wearing dark fatigues waited on the dock and watched the operation. All but one carried an assault rifle. The man without an AK-47 had a huge holster strapped to his hip. He tapped the side of his leg with a leather riding crop and despite the darkness sported mirrored aviator shades.

The captain was a large black man wearing a Greek fisherman’s cap atop his shaved head. The muscles of his chest and arms strained against his white uniform blouse. Another man was with him on the bridge wing: slightly shorter and not as muscled, he was somehow a more commanding presence than the captain. He exuded authority from his watchful eyes and the loose, casual way he carried himself. With the wing bridge lofting three stories above the quay there was no chance of their conversation being overheard. The captain nudged his companion, who’d been studying the armed troops rather than paying attention to the tricky maneuvering.

“Seems our rebel leader stepped straight out of central casting, eh, Chairman?”

“Right down to the riding whip and shades,” the chairman agreed. “Of course, we’re not beyond giving people what they expect to see, either,Captain Lincoln. That was a nice little performance with the walkie-talkie.”

Linc looked at the walkie-talkie in his big hand. The small device didn’t even have batteries in it. He chuckled softly. As the most senior African-American member of the crew, Lincoln had been tapped by the ship’s real captain, Juan Cabrillo, to act the part for the current operation. Cabrillo knew that the representative sent by Samuel Makambo, the leader of the Congolese Army of Revolution, would be more comfortable dealing with a man who shared the same skin color.

Linc looked over the rail once again, satisfied that the big freighter was holding steady. “All right,” he bellowed into the night. “Let go fore and aft lines.”

Deckhands at the stern and bow lowered thick ropes through the hawseholes. With a nod from their commander, two of the rebels slung their weapons over their shoulders and looped the lines over the rust-coated bollards. Windlasses took up the slack and the big freighter gently kissed the old truck tires slung along the length of the pier that acted as fenders. Water continued to foam at the ship’s stern as reverse thrust was maintained to fight the current. Without it, the ship would have ripped the bollards from the decaying wooden dock and drifted downstream.

Cabrillo took just a moment to check the freighter’s stations, keeping position, gauging current, windage, rudder, and power with one sweep of the eye. Satisfied, he nodded to Linc. “Let’s make a deal.”

The two stepped into the ship’s main bridge. The room was illuminated by a pair of red night-lights, giving it a hellish appearance that made its dilapidated state all the more obvious. The floors were unwashed linoleum that was cracked and peeling in the corners. The windows were dusty on the inside while the outsides were rimmed with salt crust. The sills were the graveyards of all manner of dead insects. One needle on the tarnished brass engine telegraph had broken off long ago, and the ship’s wheel was missing several spokes. The vessel carried few modern navigational aids and the radio in the shack behind the bridge could barely transmit a dozen miles.

Cabrillo nodded at the helmsman, an intense Chinese man in his early forties, who shot the Chairman a wry smile. Cabrillo and Franklin Lincoln descended a series of companionways lit only occasionally by low-watt bulbs in metal cages. They soon reached the main deck where another member of the crew waited.

“Ready to play jungle jeweler, Max?” Juan greeted.

At sixty-four Max Hanley was the second oldest member of the crew, and was only just showing the signs of age. His hair had retreated to a ginger fringe around his skull and his belt line had thickened a bit.

But he could more than handle himself in a fight and had been at Cabrillo’s side since the day Juan had started the Corporation, the company that owned and operated the tramp freighter. Theirs was an easy friendship of mutual respect borne of countless dangers faced and bested.

Hanley hoisted an attaché case from the pitted deck. “You know what they say—‘diamonds are a mercenary’s best friend.’ ”

“I’ve never heard them say that,” Linc said.

“Well, they do.”

The deal had been a month in the making, through countless cutouts and several clandestine meetings. It was pretty straightforward. In exchange for a quarter pound of rough diamonds, the Corporation was giving Samuel Makambo’s Congolese Army of Revolution five hundred AK-47 assault rifles, two hundred rocket-propelled grenades, fifty RPG launchers, and fifty thousand rounds of Warsaw Pact 7.62

mm ammunition. Makambo hadn’t asked where the crew of a tramp freighter got their hands on so much military hardware, and Cabrillo didn’t want to know how the rebel leader obtained so many diamonds.

Though coming from this part of the world, he was sure they were blood diamonds, mined by slaves in order to finance the revolution.

Able to recruit boys as young as thirteen for his army, Makambo needed weapons more than soldiers, so this shipment of arms would ensure that his attempt to overthrow the shaky government now stood a pretty good chance.
