In the Rose Garden of the Martyrs. Christopher de Bellaigue

a fine voice. The others gathered in a tight circle, near the singer, and knelt inwards. In time with the lament, they brought their arms high above their heads, and down again, so that their hands thumped against their chests.

      Gradually, the lament got faster. The arms rose and fell faster, like the pistons of a locomotive. Someone turned off the light and the men took off their shirts; their torsos glistened in the street light that came in from the window. Faster and faster, the lament went, until the singer’s voice cracked; he started sobbing into the microphone. Inside the circle, the arms were rising and falling more swiftly; when the hands hit the chests, they made the sound of bones hitting hide. Drops of sweat fell off the end of Mr Zarif’s nose. His arms ached. His chest felt raw.

      Everyone was shouting: ‘Hosseinhosseinhosseinhosseinhossein!’ and hitting their chests as hard as they could.

      After it was over, someone turned on the lights. Mr Zarif blinked. Everyone had red splotches on their chests. The room was humid. The lads put on their shirts. Then someone brought in tea and biscuits. Someone cracked a joke.

      (Standing up, hands out in supplication: ‘God! Favour us in this life and the next, and save us from the torment of hell.’)

      After they had tea, one of the men came over to Mr Zarif and introduced himself. He asked some questions, about Mr Zarif’s political and religious convictions, and the situation at his school. Mr Zarif gave him what seemed – from the man’s reactions – to be satisfactory answers. The man asked Mr Zarif to monitor the Communists, and the Mujahedin, at school. These groups had seized arms from armouries in the chaos that preceded and coincided with the Shah’s flight. Their paymasters in Moscow were trying to take advantage of the situation, to suck Iran into their zone of influence.

      (Sitting on his heels, hands on knees: ‘In the name of God, on him be praise and glory. I bear witness that God is one and that Muhammad is his servant and Prophet. Greetings and the benediction of God on Muhammad and his followers.’)

      The following week, Mr Zarif and the other members of the gang followed the Communist kids. They found out where they lived, and discovered that their dads wore big moustaches, and called one another ‘comrade’. Some of the dads worked at Isfahan’s big iron works, which had Russian managers. One or two of them socialized with Russian families. The Russian families were poor and ugly.

      One day, a couple of men arrived at the school to start political indoctrination. The men told the kids how to think about God and the Imam, and America and the Zionist Entity. When the principal saw that Mr Zarif was a friend of these men, he conceived for him a shaming fear. A kid of fifteen had become more powerful than he was.

      Mr Zarif neglected his studies. He started doing sport, pumping iron, sticking out his chest. (He was growing a beard, though not fast enough for his liking). In school, he delivered harangues, handed round pamphlets. He organized prayer meetings in the playground. If he wanted to pass on a message to another boy, he would walk into the boy’s class and whisper the message to him – the teacher would pretend not to notice.

      Mr Zarif’s boys got two of Cagney and Lacey’s favourites into the school store, and asked them some questions. They learned that Cagney and Lacey was a closet Communist. Shortly after, quite a senior person from the Revolutionary Guard arrived at the school. He spent a long time in the principal’s office. Cagney and Lacey was called in and invited to resign. The following day, at his word, ten of Mr Zarif’s lads surrounded the Communists; there were bleeding noses. The hammers and sickles got fewer.

      (Sitting on his heels: ‘The peace and munificence of God be on Muhammad. Greetings on us and the right-acting servants of God. The peace and mercy and munificence of God be on you.’)

      A few months after the Revolution, the Communists planned a meeting that was to be addressed by a high-up Communist from Tehran. Thanks to a spy he had planted among them, Mr Zarif got wind of the meeting. He went early and got a good spot near the podium. Just as the speaker was being introduced, Mr Zarif ran onto the podium and landed a good one on his nose. Before anyone had time to react, he hurled himself into the section of the crowd that was thinnest. He was small enough, and fast enough, to get away with only a broken rib.

      At the beginning of November 1979, radical students allied to the Imam seized the American Embassy in Tehran, taking the staff hostage. The students announced that they would release the hostages only when President Carter handed over the Shah, who had been allowed into America for cancer treatment. Bazargan resigned; his government had been trying to repair relations with the US. After Bazargan’s departure, the Imam placed the government directly under the control of his kitchen cabinet, the Islamic Revolutionary Council.

      Mr Zarif was delighted: he remembered that the Revolution was made up of steps.

      Nowadays, when people think of the mullahs’ revenge, they think of Sadegh Khalkhali. There were scores of clerics who were more important than him; they actually took decisions, rather than implemented and interpreted the decisions of others, as Khalkhali did. Many of these mullahs were easier on the eye than Khalkhali; they had politer turns of phrase, more impressive qualifications. Khalkhali was a poor kid from the Azeri northwest, short on education outside the seminary, rotund, bald and coarse.

      During the Shah’s time, Khalkhali had upset people by writing a treatise depicting Cyrus the Great, founder of the Achaemenian empire and a figure whom the Shah admired, as a sodomite. He’d been imprisoned and internally exiled. Then, a few days after the Revolution, Khomeini appointed him to be a judge in the revolutionary court that was to try beneficiaries of the old regime and opponents of the new one. Khalkhali toured the country, trying monarchists and counter-revolutionaries. (Over a three-month period, he claimed to have condemned more than four hundred people to death. They included former senators, a radio presenter and a mob leader.) His pugnacious, fat face became as famous as his jokes, which often featured references to executions. V. S. Naipaul, who visited Khalkhali at the height of his notoriety, likened him to a jester at his own court.

      Khalkhali made an indelible impression on Elaine Sciolino, an American journalist who witnessed one of the trials he presided over; she remembered him in a book she wrote two decades later. To counter the extremely hot weather, Sciolino recalls, Khalkhali removed his turban, cloak and socks, which must have made him look like a turnip. He sat on the floor and picked his toes while hearing the evidence against a defendant. He repeatedly left the room during the testimony of witnesses.

      His most famous victim was Amir Abbas Hoveida, and Khalkhali must have enjoyed that bit of business. Hoveida was Khalkhali’s antithesis, thirteen years the Shah’s prime minister, a man whose Northampton brogues Khalkhali could not, before the Revolution, have dreamed of polishing. Hoveida was a francophone, but he also knew Arabic – the Arabic of Beirut society, not the Qoran. Even after their divorce, Hoveida’s wife made sure that a fresh orchid reached him every morning for his buttonhole. He’d not been personally venal or murderous, but he’d closed his eyes to the atrocities of others. Khalkhali charged him with waging war on God and corruption on earth. Over two court sessions, separated by several weeks, Khalkhali pounded the defendant’s moral ambivalence like saffron under a pestle.

      At lunchtime on Hoveida’s last day, Khalkhali reports in his memoir, the prisoner was treated to a repast of rice, lamb and broad beans. Khalkhali claims to have made do with bread and cheese. (Next to photographs of him, excessively crapulent, this ascetic self-portrayal is unconvincing.) During the afternoon session, Khalkhali didn’t allow Hoveida a defence counsel, nor was a jury present. As the presiding judge, Khalkhali didn’t pretend to be impartial; in the vehemence of his harangues, he rivalled the prosecutor.

      By trying Hoveida, Khalkhali jabbed his finger in Bazargan’s eye. Bazargan disapproved of the revolutionary court – he was planning for Hoveida an exemplary trial that would establish the Revolution’s reputation for justice and moderation. But Khalkhali, who plausibly claims to have taken hints from Khomeini, had different ideas. He gave orders that no one was to be allowed out of the prison where the trial was taking place. To ensure that word didn’t reach Bazargan, he locked the prison telephones in a fridge. And so Hoveida was sentenced and shot in the prison courtyard. His final words were patrician, and a bit surprised: ‘It
