Moore's great gift is his ability to make Thatcher's story fresh again, and above all to remind us of how odd she was ... During the decade and a half he worked on this authorised biography - of which this is only the first volume - Moore had unprecedented access to her private papers, on condition that nothing be published until after her death. He interviewed just about everyone who knew Thatcher, from her private secretaries to her political enemies, and he did so meticulously, in reverse order of age ... The thoroughness of the research, the hundreds of interviews, and above all the access to her family and friends, enabled Moore to produce a multifaceted picture of a compelling life ... Although this is very much a narrative biography, it is also a book about ideas: where they come from, how they affect people and how they get shaped into policies ... In the end, this combination of biography and intellectual history works perfectly ... To understand what happened to Britain during her prime ministership and afterwards, it really is important to understand who she was: Moore's Thatcher will now become the definitive account -- Anne Applebaum * Daily Telegraph * Sixteen years ago, Mrs Thatcher picked Moore to write her authorised biography, not to be published until after her death. When his appointment was announced, her supporters cheered, and her opponents groaned: Moore was, they both felt, strongly Thatcherite, and would surely give her the easiest of rides. Both sides have grossly underestimated him. With this first volume ... Moore has produced a biography so masterly - so packed with fascinating detail, with such a strong narrative drive, propelled by a central character who is at the same time both very bizarre and very conventional - that it comes as close as biography can come to being a work of art ... One of the many strengths of his book is that it never loses sight of just how unusual she was, in terms of both her personal psychology and her place in public life ... This book is a triumph of diligence. Moore interviewed 315 people, and was clearly blessed with the knack of getting them to open up. Ribald insults, gossip, political secrets, private grievances and funny stories - many of them very, very funny - fly off every page. But it is also a triumph of narrative art and human understanding, at its centre a peculiar force of nature, never to be repeated. 'People are fascinated, appalled, delighted by her,' writes Moore. 'Many think she saved Britain, many that she destroyed it.' I would be surprised if they don't all agree, though, that this is one of the greatest political biographies ever written -- Craig Brown * Mail on Sunday * He mines his sources skilfully without becoming their captive. His prose is more considered and his conclusions more nuanced than his ... journalism. He is not afraid to address the contradictions and tease out the inconsistences of his subject. Nor to be critical, sometimes deeply so. The result is to paint a much more multidimensional portrait of Thatcher than the caricature heroine adored by the right or the devil incarnate loathed by the left ... The prose is intricate, elegant and laced with dry humour ... This biography ... immensely adds to our knowledge and understanding of the longest-reigning prime minister of the democratic age -- Observer * Andrew Rawnsley *
