It sounds almost too extraordinary to be true: a Kiwi advertising executive makes a pilgrimage across the byways of China, where tourists are rarely seen, and tracks down a long lost son of Mao Tse Tung.
But then Richard Loseby, the advertising executive in question, has form for doing extraordinary things. His other two books, set primarily in Afghanistan, are among the best travel books I've read, and I've read a lot of them.
For the record, Loseby was born in Port Moresby, Papua New Guinea; grew up in Australia and moved to New Zealand when he was 8. In 1980, he ventured into advertising as a copywriter, working in London from 1985 to 1993 before returning to Auckland.
His first book told of his terrifying journey alone across war-torn Afghanistan. The equally remarkable second is about his return to that benighted land to find out what happened to a young Afghan who befriended him.
So it is entirely believable that a couple of chance encounters - one with a schoolteacher in a tea house in a dusty town in western China, the other with an advertising agency receptionist and part-time dancer in a dubious nightclub in Bangkok - should lead to him setting off on another adventure. The inspiration for this latest quest is the tale told by both of how at the start of the Long March, Mao tse Tung and his third wife He Zizhen left behind their son, Little Mao, because he would have hindered their flight from the Nationalist forces.
