‘Ai! My eyes are glad to see you.’ The young man with the long scar down one side of his face greeted Chang with a rush of relief. ‘To have you back, alive and still cursing, my friend, it means I shall sleep tonight. Here, drink this, you look as if you need it.’

The light flickered as the torch flames hissed and spat like live creatures on the wall.

‘Yuesheng, I thank you. They came close, this time, the grey scorpions of Chiang Kai-shek. Someone had whispered in their ear.’ Chang drank the small glass of rice wine in one swallow and felt it burn life back into his chilled bones. He helped himself to another.

‘Whoever it was will have his tongue cut out.’

They were in a cellar. The stone walls dripped with water and were covered in vivid-coloured lichen, but it was large and the sounds of the printing press were deadened by the thick walls and the heavy ceiling. Above them stood a textile factory where machines rattled all day, but only the foreman knew of the machine under his workers’ feet. He was a trade union man, a Communist, a fighter for the cause, and he supplied oil and ink and buckets of raw rice wine to the nighttime activists. Since the Kuomintang Nationalists had swept into power and Chiang Kai-shek swore to wipe the Communist threat off the face of China, each breath was a danger, each pamphlet an invitation to the executioner’s sword. Half a dozen determined young faces clustered around the presses, half a dozen young lives on a thread.

Yuesheng pulled a strip of dried fish from his bag and handed it to Chang. ‘Eat, my friend. You will need your strength.’

Chang ate, his first food in more than three days. ‘The latest posters are good, the ones demanding new laws on child labour,’ he said. ‘I saw several on my way here, one even on the council chamber’s door.’

‘Yes.’ Yuesheng laughed. ‘That one was Kuan’s doing.’

At the mention of her name a slender young woman glanced up from where she was stacking pamphlets into sacks and gave Chang a nod.

‘Tell me, Kuan, how do you always manage to find the most insulting places to stick your posters, right under Feng Tu Hong’s nose?’ Chang called above the clattering noise of the press. ‘Do you fly with the night spirits, unseen by human eye?’

Kuan walked over. She was wearing the loose blue jacket and trousers of a peasant farmer, though she had recently graduated from Peking University with a degree in law. She had serious black eyes. She did not believe in the soft smiles that most Junchow women offered to the world. When her parents threw her out of the family home because she humiliated them by cutting her hair short and taking a job in a factory, it only sharpened her desire to fight for women, so that they would no longer be owned like dogs by fathers or by husbands, to be kicked at will. She possessed the fearlessness of the fox girl but inside her there was no flame, no light that burned so bright it lit up a room, no heat so fierce that lizards scurried to be near her.

Where was Lydia now? Cursing him, he had no doubt. The image of her fox eyes, narrowed and waiting for him full of fury, sent a laugh through him and Kuan mistook his pleasure. She gave Chang one of her rare smiles.

‘That camel-faced chairman of the council, Feng Tu Hong, deserves such special treatment,’ she said.

‘Tell me. What is new while I’ve been gone?’

The smile faded. ‘Yesterday he ordered a purge of the metal-workers in the iron foundry, those who were asking for safer conditions at the furnaces.’

‘Twelve were beheaded in the yard. As a warning to others,’ Yuesheng spat out and ran a hand down the sword scar on his own face. It seemed to pulsate and darken.

A surge of rage tore through Chang. He closed his eyes and focused his mind. Now was not the time. This moment was surrounded by fire. He needed control, with danger so close.

‘Feng Tu Hong’s time will come,’ he said quietly. ‘I promise you that. And this will bring it faster.’ He pulled a piece of paper from a leather pouch that hung from his neck.

Yuesheng snatched it up, read it through, and nodded with satisfaction. ‘It’s a promissory note,’ he announced to the others. ‘For rifles, Winchesters. A hundred of them.’

Six faces found smiles and one young man punched an ink-stained fist into the air in salute.

‘You have done well,’ Yuesheng said, pride in his voice.

Chang was pleased. He and Yuesheng were almost brothers in their friendship. It was the rock on which they stood. He placed a hand on Yuesheng’s shoulder and their eyes met in understanding. Each breath was one they earned.

‘The news from the south is good,’ Chang told him.

‘Mao Tse-tung? Is our leader still evading the grey bellies’ snares?’

‘He narrowly escaped capture last month. But his military camp in Jiangxi is expanding every day, where they come like bees to a hive from all over the country. Some with no more than a hoe in their hand and belief in their heart. The time is coming closer when Chiang Kai-shek will discover that his treachery and betrayal of our country have signed his own death warrant.’

‘Is it true there was another skirmish near Canton last week?’ Kuan asked.

‘Yes,’ Chang said. ‘A train full of Kuomintang troops was blown up and…’

A loud crash drowned out his voice and the sound of the press as the metal door burst open at the top of the stairs and a boy hurled himself into the cellar, eyes huge with panic.

‘They’re here,’ he screamed. ‘The troops are…’

A shot cracked through the cellar and the boy collapsed facedown on the earthen floor, a bright red stain etched on the back of his jacket.

Instantly the cellar was full of movement. Each knew what to do. Yuesheng had prepared for this moment. Torches were doused. In the darkness enemy boots pounded down the stairs, voices raised, commands thrown at shadows, and two more shots made the walls sing. But in the far corner a ladder was ready. Well-oiled bolts slid back. A hatch was thrown open. But the square of night sky was paler, leaving the figures silhouetted against the opening as they started to slip through it one by one.

Standing last at the base of the ladder beside Yuesheng, Chang saw the dim outline of a soldier approach from the stairs, and with a lightning kick he tore the man’s jaw from its socket and heard a high whinny of pain. In a flash Chang had seized his rifle and was sending a blast of bullets screaming around the cellar.

‘Go,’ he shouted at Yuesheng.

‘No. You leave first.’

Chang touched his friend’s arm. ‘Go.’

Yuesheng delayed no longer and sped up the ladder. Chang fired once more and felt a Kuomintang bullet whistle through his hair in reply, and then he leaped up the rungs right on Yuesheng’s heels. Bullets tore into the hatch opening from below and suddenly Chang felt a dead weight crash down on him. It was as if his own heart had been torn out.

He seized Yuesheng’s body on his shoulder, sprang through the hatch, and raced away into the darkness.
