He pointed out the side window. "Yes, I know them. The river comes out between them at a waterfall."

"Which way is the camp?"

"That way, far that way."

"How far?"

"Two full days" march."

"Seventy nautical miles, Sean translated time into distance.

We aren't too far out. Thank you, Ferdinand." Sean broke out of the monotonous figure-eight pattern and leveled the Hercules" gigantic wings.

Still low against the forest, he flew westward, the direction in which Ferdinand had pointed, while behind them the dawn came on apace, turning the eastern sky a hazy carmine. They chased the shades of night as they fled across the dark hills.

Sean aimed the nose of the Hercules at the gap Ferdinand had pointed out and checked his wristwatch against the panel clock.

"Time for News Desk on the Africa Service of the BBC," he said, and fiddled with the radio controls. He picked up the familiar signature tune on 15,400 megahertz.

"This is the BBC. Here again are the news headlines. In the United States, Governor Michael Dukakis has convincingly carried the state of New York against Jesse Jackson in his bid for the Democratic Party presidential nomination. Israeli troops have shot dead two more protesters in the occupied Gaza Strip. One hundred and twenty passengers have died in an airline crash in the Philippines. Renamo rebels have high jacked an R.A.F Hercules transport from a ZimbabFean Air Force base near the town of Umtali. They have flown' it into Mozambique, where it is being pursued by aircraft " oF the Zimbabwean and Mozambican air forces. A spokesman said that both President Mugabe and President Chissano have given orders that the aircraft, which has no hostages on board but which contains sophisticated modern weapons intended for use against the rebels, is to be destroyed at all costs."

Sean switched off the set and smiled across at Job. "You never thought you'd make the news headlines, did you?"

"I can do without the fame," Job admitted. "Did you get the bit about being pursued and destroyed at all costs?"

The Hercules was fast approaching the gap in the fine of hills The light had strengthened so that Sean could make out the pearly gleam in the throat of the pass where the river tumbled down over wet black rock.

"Incoming!" Job yelled suddenly. "One o'clock low!"

With his extraordinary eyesight, he had picked it up an instant before Sean did. The Hind had been lying in ambush, squatting like some monstrous insect in a hidden clearing in the forest, guarding the entrance to the river pass.

As Sean saw it, he clearly understood the tactics Frelimo had used to cut him off from the Renamo lines. They would have sent the full squadron of Hinds in during the night, as soon as they guessed where he was headed.

Operating at the limits of their range, the Hinds would have settled in a defensive line, landing to conserve fuel, hiding in the forest and sweeping with their pulse radars, listening in the silence for the sound of the Hercules" engines.

Almost certainly they had guessed he would use the river as a navigational landmark. There would probably be other gunships waiting further upstream, forming an intercepting ring around the Renamo lines, but, erring too far south, Sean had run headlong into this one.

It leaped out of the forest, rising vertically on the silver blur of its rotor, the deformed nose drooping like a minotaur lowering its head to charge, blotched with leprous camouflage, obscenely ugly and deadly.

It was still below them but coming up swiftly, swelling in size as they converged. Within moments its Gatling cannon would bear; already it was training upward. Sean reacted without thought.

He rammed all four throttle controls fully open, and the great turbos screeched as he thrust the nose down, diving straight at the helicopter.

He saw the rockets leaving the weapon pods under the Hind's wings, each one a black dot in the center of a white wreath of smoke as it dropped clear. He remembered the statistics Job had read him only minutes before. The Hind carried two AT-2 Swatter imssiles and four 57-men rocket pods.

He dived the Hercules through the barrage of rockets. They flashed past his head, a storm of smoke and death, and the Hind was only two hundred meters ahead, still rising to meet him, firing rockets at point-blank range but not allowing for his violent maneuver.

"Hold on!" Sean shouted at Job. "I'm going to ram the bastard."

The killing rage was on him, sweet and hot in his blood. There was no fear at all, just the marvelous urge to destroy.

At the last moment, the pilot of the Hind guessed his intention.

They were so close that through the canopy Sean could clearly make out his features below the helmet. The Russian's face was doughy white and his mouth a shocking red slash like an open wound. He flicked the Hind over on its side, almost inverting it completely, closing down his collective so the gunship fell like a lead weight, trying to duck under the Hercules" outspread pinions. Got you, you son of a bitch!" Sean exulted, and the Hercules" wing hit the tail of the gunship. The shock of impact threw Sean against his shoulder straps, and the Hercules shuddered and lurched. The airspeed was knocked off her and she quivered on the edge of the stall, only two hundred feet above the forest top.

"Come on, pussycat," Sean whispered like a lover. He was babying the controls, coaxing her with gentle fingers. Her damaged wing was down, tatters of torn metal hanging from it, whipping and banging in the slipstream, and the forest tops reached up like the talons of a predator to claw them out of the sky.

"Fly for me, darling," Sean whispered, and the four engines, howling with the effort, held her up, then gradually lifted her clear.
