This is a rarity - a sensible book on an emotive subject - yet I wish I liked it more. The first half, dealing with Diana's origins, impact and demise is excellent. Harrison draws a strong contrast between the Diana of instant myth and the private individual, whom his sources suggest was spiteful, self-obsessed and rather unlikable.
Yet Harrison's conclusions fail to live up to this start. This is partly because he aspires to an academic neutrality which undercuts the vigor of argument, but also because his material is rather weak. In brief, he sees Diana as the central figure in a sentimental new age mythos, perfectly attuned to the post-election atmosphere of 1997. No-one could disagree - but Harrison treats the Diana cult with a kid-glove respect which obviously does not reflect his real estimation.
Much of the material in these later chapters is drawn from the wilder margins of the internet, posing another problem. Harrison accepts her devotees estimate of the princesses' importance, but the marginalisation of the full-blown Diana cult, with its channeled messages and miraculous apparitions, suggests that she has already sunk into the near fiction of an Elvis, Monroe or JFK - an essentially meaningless pop-culture pin-up. Nothing in Harrison's book leads me to ask with him if "a sizable church of Diana will develop" because the answer is so obviously "no". The author makes a watertight case for Diana as the embodiment of a particular historical moment, but seemingly fails to realise just what this implies - that the moment has already passed.
