Juggernaut

Zimmerman yelled, 'No, Mick – don't take it!' He straight-armed a soldier and at the same moment Kirilenko whirled on another and floored him with a massive kick to the groin. In horror I stared at Dufour's truck. McGrath stumbled just as he reached it and lost his grip on the sub-machine-gun.

'He's hit!'

McGrath heaved himself up and into the cab and hurled the driver out with a violent effort. The truck picked up speed and raced up the spur road towards the rig.

Beside me Wadzi opened his mouth to shout an order.

I threw myself at him and we went down in a tangle of arms and legs. I clawed for the revolver at his belt as Thorpe threw himself down to pin Wadzi's legs. As I scrambled to my feet with the gun I saw Sadiq arch out of the staff car, the rifle flying from his hands. He crashed in a sprawling mass onto the roadway. Kirilenko used his boot again on Colonel Wadzi's breastbone and the officer subsided, coughing and writhing. His men scattered.

I gasped, 'Harry, does Mick know?'

'Yes. I told him! Oh my God – it'll go any second!'

And then Dufour had hold of my arm, gripping it like a vice and shaking me violently. 'Mannix -I tried to tell you, I tried! It will not explode!'

'Of course it will. I've wired it!' Zimmerman snapped.

Dufour stammered, 'Only four bottles of gelignite… right in front…'

'What?'

As we spoke the truck rocketed up the slope, fired on from all sides. If the timing mechanism failed the bullets would do the job for us. But what in God's name was Dufour trying to say?

'Not… gelignite! Mother of God, Mannix, it's gin!'

A blinding light of understanding hit me. Spirits were illegal and therefore precious in Bir Oassa, a predominantly Arab community. The gelignite was a double bluff, to prevent officials from probing further into Dufour's illicit cargo. Few would tamper with such a load. He had been smuggling alcohol to the oilfields.

And now, instead of the shattering explosion that we'd hoped for there would be at most a small thump, a brief shock. The damage would be to the truck itself. McGrath's heroic, insane act would be all for nothing.

'Oh dear God.'

We stood frozen. Wadzi was hurt but alive and he'd be on his feet again any moment. We were still surrounded by armed men, and there was no path to freedom; nowhere to go. The revolver hung loosely in my hand and I felt sick and stunned. We had gambled and lost.

The truck veered off course, clawing its way across the dirt shoulder of the upper road. It was alongside the rig by now. Its erratic steering could only mean that McGrath was badly wounded or perhaps even already dead. It rocked and shuddered to a halt, dwarfed by the enormous structure of the rig. It half tilted off the shoulder and hung over the edge of the sheer drop to the ferry yard. My heart hammered as I saw a figure inside the cab – my last sight of Mick McGrath.

The truck exploded.

It was not, indeed, a very great event. The truck blew apart in a sheet of flame. The men and other vehicles nearby were sheltered from damage by the rig itself, an object too massive to be affected.

But under the truck was the roadway. Years old, carelessly maintained, potholed and crumbling; at this spot it clung to the hillside over a drought-dry, friable crust of earth knitted together with shallow-rooted vegetation. The road had no more stability than a child's sandpit.

The exploding truck tore this fragile structure like a cobweb.

A cracking fissure ran along the ancient tarmac just where the full weight of the rig already bore down too heavily for safety. There was a gigantic roar, a rolling billow of dust, and the entire hillside gave way under the terrible pressure of the rig.

With its load of the three hundred ton transformer and the coupled tractors the rig began to roll and tumble down the slope towards the ferry yard, dreadful in its power. With it came huge chunks of tarmac, earth, boulders and debris. It thundered downwards, gaining momentum, the air split with the tortured scream of metal and the roar of the landslide that came with it.

Men scattered like ants and fled in horror from the monstrous death racing down towards them. Engines screamed into life, rifles clattered to the ground as the soldiers dashed frantically for safety. The rig crashed with appalling, ponderous strength into the first of the outbuildings, crushing them to matchwood. The paving of the yard crumbled under the onslaught.

We stood in shock and terror as the animal we had led about so tamely turned into a raging brute trumpeting destruction. And then there was a scream wilder than any I'd yet heard.

'No! No! Stop it – don't let it happen – '

Kemp burst between us, his face contorted, his eyes bulging in horror, and ran straight towards the rig. We took a couple of steps after him and stopped, helpless to prevent the awful thing Kemp was about to do.
