A groundbreaking examination of a terrifying murder & its aftermath by the bestselling author of Hanns & Rudolf & The House by the Lake. In June 2006, police were called to number 9 Downshire Hill in Hampstead to investigate reports of unusual card activity. The owner of the house, Allan Chappelow, was an award-winning photographer & biographer, an expert on George Bernard Shaw, & a notorious recluse, who had not been seen for several weeks. Someone had recently accessed his bank accounts, & attempted to withdraw large amounts of money. Inside the darkened house officers found piles of rubbish, trees growing through the floor, &, in what was once the living room, the body of Chappelow, battered to death, partially burned & buried under four feet of paper. The man eventually convicted of his murder was a Chinese dissident named Wang Yam: a man who claimed to be the grandson of one of Mao`s closest aides, & a key negotiator in the Tiananmen Square protests. His trial was the first in modern British history to be held `in camera`: closed, carefully controlled, secret. Wang Yam has always protested his innocence. Thomas Harding has spent the past two years investigating the case, interviewing key witnesses, the investigating officers, forensic experts, & the journalists who broke the story, & has unearthed shocking & revelatory new material on the killing, the victim & the supposed perpetrator. It is a story that has been described in the press & by the leading detective as `the greatest whodunnit` of recent years: an extraordinary tale of isolation, deception, espionage & brutal violence, stretching from the quiet streets of north London to the Palace of Westminster & beyond. It is an explosive new work of non-fiction from an author working at the height of his powers.
