THE GOOD
1. Dutch historian Frank Dikotter, who is a history professor at the University of Hong Kong, has shown the way for fellow chroniclers to marshal what is oft-unwieldy research into an ordered, riveting read. His approach to the Cultural Revolution has been first to give readers the big picture on it, followed by a punchy chronology of how the revolution unravelled, culminating in a narrative that fleshes out each blow.
2. Dikotter was schooled in the French maxim, "If you think clearly, you will write clearly", and it shows. He is an elegant, economical writer, displaying in fast-flowing prose the prowess of one in command of his subject. There is also discernible balance, warmth even, in his tone, such as when he tries to help readers understand the peccadillos and likely motivations of such icons of cruelty as Joseph Stalin and Mao Zedong. Here he is, for instance, on the relationship between the two: "Ever since the death of Stalin in 1953, Mao had wished to claim leadership of the socialist camp. Even during Stalin's lifetime, Mao had considered himself a more accomplished revolutionary. It was he who had brought a quarter of humanity into the socialist camp in 1949."
THE BAD
1. This book is bereft of any visual element, not even a mugshot of Dikotter. Powerful as his storytelling is, people prefer lingering over images than words, and even diehard readers would appreciate photographs and maps to help them breathe amid his intense narrative.
THE IFFY
1. In describing the horrors which the misanthropic Red Guards visited upon China's upper classes, Dikotter takes a few leaves out of earlier memoirs of The Cultural Revolution, notably Nien Cheng's Life And Death In Shanghai, Jung Chang's Wild Swans and Gao Yuan's Being Red: A Chronicle Of The Cultural Revolution. In fact, he quotes them directly in his book. Reading him might have been a far more valuable experience if he had compared the accounts he found in recently declassified documents with theirs and gave his take on the subject.
Fact File: Lost sleep trying to write well
On a hot, humid summer's day about five years ago, Dutch historian Frank Dikotter walked into a provincial government archive in China. His aim? To dig up fresh information on the country's devastating Cultural Revolution, from the late 1960s to the mid-1970s.
Recalling the moment over the telephone last Wednesday, Professor Dikotter, who writes and speaks Chinese fluently, said: "There was an elderly woman in charge and I told her that I wanted to work on the period between 1962 and 1976.
"She said, 'Young man, you must understand that during that period, we had a Cultural Revolution... There was a lot of turmoil, so I cannot guarantee that we have complete archives. But we will do our very best to help you.'"
Prof Dikotter, who is now 54 and teaches history at the University of Hong Kong, thanked her deeply.
"I thought she was going to tell me off and say, 'You can't read everything on the Cultural Revolution.' But not at all; she was very helpful," he recalled.
"China's archivists are generally extremely professional and they will do their best to help you. But I'm not sure they were secretly feeding me documents that I shouldn't be reading."
But surely there were archivists who turned him away or tried to hinder his research? After all, even after 50 years, the brutal revolution is still something too raw for most Chinese to talk about.
Noting that archives existed in every city, country and province of China, he said: "I'm not saying it was without difficulty that I managed to read this material. But when someone tells you that the documentation is not open to outsiders or when you realise that the material you're being given is actually not very good, you just move on, go somewhere else. You do have to be persistent."
Such persistence had paid off for him. In 2011, he won the prestigious Samuel Johnson Prize for non- fiction, for his book Mao's Great Famine, an account of the mass starvation of an estimated 45 million people in the 1950s under Mao.
That success, he admitted in this interview, made it even more difficult for him to write The Cultural Revolution, the third in a trilogy which began with his prize- winning book.
He said: "You think, 'Oh my god, will I be able to do the same thing again? Will I be as good?'
"Before I started writing The Cultural Revolution in the summer of 2014, I became so panicky. I lost so much sleep worrying about it that I just thought, 'Well, the only way to confront my worries was to sit down and start writing.'
"And the moment I put pen to paper and had 1,000 words on the first day, I felt, 'This was going okay. I could actually do this.'"
Such self-doubt is humbling when you consider that he has been a scholar of modern China for the last 30 years. It was his first love, 19th-century Russian literature - particularly the work of Fyodor Dostoyevsky - that led to his passion for the history of China.
Born in the Netherlands, his father's work at the Dutch State Mines took his family around the world.
As an undergraduate at the University of Geneva, the young Dikotter studied Russian and Chinese. When he learnt that access to the Soviet Union's literary archives was nigh impossible then, his Chinese teacher suggested that he visit China and delve into its archives on Russia instead.
He never looked back.
From 1985 to 1986, he travelled around China, with Nankai University in Tianjin as his base. There were so few foreigners there then, he recalled, that a postcard from his Canadian friend, addressed simply to "Frank from Holland", reached him in good time because in Tianjin then, there were only about 100 foreign students, 10 among whom were Dutch and, among them, there was "only one Frank".
He moved to Hong Kong 11 years ago with his British wife, retired lawyer Gail Burrowes, to immerse himself even more in the ways of China - and, of course, to be closer to its archives, which he said had been gradually declassified since the mid-1990s.
It helped, he added, that his two stepsons were already grown up then and he and his wife had driven the younger of the two to university in Wales shortly before the couple upped sticks for balmier Hong Kong.
He said: "It was the absolute perfect moment in terms of timing. We were free and ready for a new challenge."
