‘Just a few atrocity photographs…’ Ryan stood up and began to put on his webbing. Whatever he thought of Dr Edwards, the reality of the civil war remained, the only logic that he recognised. ‘Doctor, I have to go back to Beirut.’

‘It’s too late, Ryan. If we let you return, you’d endanger the whole experiment.’

‘No one will believe me, doctor. Anyway, I must find my sister and Aunt Vera.’

‘She isn’t your sister, Ryan. Not your real sister. And Vera isn’t your real aunt. They don’t know, of course. They think you’re all from the same family. Louisa was the daughter of two French explorers from Marseilles who died in Antarctica. Vera was a foundling brought up by nuns in Montevideo.’

‘And what about…?’

‘You, Ryan? Your parents lived in Halifax, Nova Scotia. You were three months old when they were killed in a car crash. Sadly, there are some deaths we can’t yet stop..

Dr Edwards was frowning at the wall map of Beirut visible through the plastic window. A signals sergeant worked frantically at the huge display, pinning on clusters of incident flags. Everyone had gathered around the monitor screens. An officer waved urgently to Dr Edwards, who stood up and left the office. Ryan stared at his hands while the two men conferred, and he scarcely heard the physician when he returned and searched for his helmet and side-arm.

‘They’ve shot down the spotter plane. I’ll have to leave you, Ryan — the fighting’s getting out of control. The Royalists have overrun the Football Stadium and taken the UN post.’

‘The Stadium?’ Ryan was on his feet, his rifle the only security he had known since leaving the city. ‘My sister and aunt are there! I’ll come with you, doctor.’

‘Ryan… everything’s starting to fall apart; we may have lit one fuse too many. Some of the militia units are shooting openly at the UN observers.’ Dr Edwards stopped Ryan at the door. ‘I know you’re concerned for them, you’ve lived with them all your life. But they’re not-’

Ryan pushed him away. ‘Doctor, they are my aunt and sister.’

It was three hours later when they reached the Football Stadium. As the convoy of UN vehicles edged its way into the city, Ryan gazed at the pall of smoke that covered the ruined skyline. The dark mantle extended far out to sea, lit by the flashes of high explosives as rival demolition squads moved through the streets. He sat behind Dr Edwards in the second of the armoured vans, but they could scarcely hear themselves talk above the sounds of rocket and machine-gun fire.

By this stage Ryan knew that he and Dr Edwards had little to say to each other. Ryan was thinking only of the hostages in the overrun UN post. His discovery that the civil war in Beirut was an elaborate experiment belonged to a numb area outside his mind, an emotional black hole from which no light or meaning could escape.

At last they stopped near the UN post at the harbour in East Beirut. Dr Edwards sprinted to the radio shack, and Ryan unstrapped his blue helmet. In a sense he shared the blame for this uncontrolled explosion of violence. The rats in the war laboratory had been happy pulling a familiar set of levers — the triggers of their rifles and mortars — and being fed their daily pellets of hate. Ryan’s dazed dream of peace, like an untested narcotic, had disoriented them and laid them open to a frenzy of hyperactive rage…

Ryan, good news!’ Dr Edwards hammered on the windscreen, ordering the driver to move on. ‘Christian commandos have retaken the Stadium!’

‘And my sister? And Aunt Vera?’

‘I don’t know. Hope for the best. At least the UN is back in action. With luck, everything will return to normal.’

Later, as he stood in the sombre storeroom below the concrete grandstand, Ryan reflected on the ominous word that Dr Edwards had used. Normal…? The lights of the photographers’ flashes illuminated the bodies of the twenty hostages laid against the rear wall. Louisa and Aunt Vera rested between two UN observers, all executed by the Royalists before their retreat. The stepped concrete roof was splashed with blood, as if an invisible audience watching the destruction of the city from the comfort of the grandstand had begun to bleed into its seats. Yes, Ryan vowed, the world would bleed The photographers withdrew, leaving Ryan alone with Louisa and his aunt. Soon their images would be scattered across the ruined streets, pasted to the blockhouse walls.

‘Ryan, we ought to leave before there’s a counterattack.’ Dr Edwards stepped through the pale light. ‘I’m sorry about them — whatever else, they were your sister and aunt.’

‘Yes, they were.’

‘And at least they helped to prove something. We need to see how far human beings can be pushed.’ Dr Edwards gestured helplessly at the bodies. ‘Sadly, all the way.’

Ryan took off his blue helmet and placed it at his feet. He snapped back the rifle bolt and drove a steel-tipped round into the breech. He was only sorry that Dr Edwards would lie beside Louisa and his aunt. Outside there was a momentary lull in the fighting, but it would resume. Within a few months he would unite the militias into a single force. Already Ryan was thinking of the world beyond Beirut, of that far larger laboratory waiting to be tested, with its millions of docile specimens unprepared for the most virulent virus of them all.

‘Not all the way, doctor.’ He levelled the rifle at the physician’s head. ‘All the way is the whole human race.’

Dream Cargoes

Across the lagoon an eager new life was forming, drawing its spectrum of colours from a palette more vivid than the sun’s. Soon after dawn, when Johnson woke in Captain Galloway’s cabin behind the bridge of the Prospero, he watched the lurid hues, cyanic blues and crimsons, playing against the ceiling above his bunk. Reflected in the metallic surface of the lagoon, the tropical foliage seemed to concentrate the Caribbean sunlight, painting on the warm air a screen of electric tones that Johnson had only seen on the nightclub faades of Miami and Vera Cruz.

He stepped onto the tilting bridge of the stranded freighter, aware that the island’s vegetation had again surged forward during the night, as if it had miraculously found a means of converting darkness into these brilliant leaves and blossoms. Shielding his eyes from the glare, he searched the 600 yards of empty beach that encircled the Prospero, disappointed that there was no sign of Dr Chambers’ rubber infaltable. For the past three mornings, when he woke after an uneasy night, he had seen the craft beached by the inlet of the lagoon. Shaking off the overlit dreams that rose from the contaminated waters, he would gulp down a cup of cold coffee, jump from the stern rail and set off between the pools of leaking chemicals in search of the American biologist.

It pleased Johnson that she was so openly impressed by this once barren island, a left-over of nature seven miles from the north-east coast of Puerto Rico. In his modest way he knew that he was responsible for the transformation of the nondescript atoll, scarcely more than a forgotten garbage dump left behind by the American army after World War II. No one, in Johnson’s short life, had ever been impressed by him, and the biologist’s silent wonder gave him the first sense of achievement he had ever known.

Johnson had learned her name from the labels on the scientific stores in the inflatable. However, he had not yet approached or even spoken to her, embarrassed by his rough manners and shabby seaman’s clothes, and the engrained chemical stench that banned him from sailors’ bars all over the Caribbean. Now, when she failed to appear on the fourth morning, he regretted all the more that he had never worked up the courage to introduce himself.

Through the acid-streaked windows of the bridge-house he stared at the terraces of flowers that hung from the forest wall. A month earlier, when he first arrived at the island, struggling with the locked helm of the listing freighter, there had been no more than a few stunted palms growing among the collapsed army huts and water-tanks buried in the dunes.
