Charitable endeavour exalts the prestige and the status of the giver. This may sound unduly cynical but as with all philantrophic activity, it is not easy to unravel the mutually reinforcing motives of selflessness and self-interest. All that can safely be said is that most members of the royal family have difficulty distinguishing between concern about society, concern about the social order and concern about what best to do so they can remain at the top of it.

Kitty Kelley's method, already perfected in her unauthorised and unflattering biographies of Frank Sinatra and Nancy Reagan, is to write bestsellers that take what she describes as an 'unblinking look' at their subjects - which might, of course, mean that her eyes are permanently open or permanently closed... the result is a work so bad that Britons cannot realise how fortunate they are in being unable to buy it. The great mistake with this book is not that it has been published in Britain, but that it has actually been published anywhere else.

Royal relationships across the generations have often been strained and distant, rather than close and affectionate. Most eldest sons, interminably waiting to become king, have not been on the best of terms with the sovereign to whose death they look forward with a debilitating combination of guilt-ridden anxiety and eager anticipation. And younger sons (and daughters, too) have often found their lives empty of purpose: cut off by their royal statius, but unable to find anything rewarding with which to fill the time.

Of all the memorable phrases that have been minted and mobilised to describe modern British royalty, 'constitutional monarchy' is virtually the only one which seemes to have neither been anticipated nor invented by Walter Bagehot. It was he who insisted that 'a princely marriage is the brilliant edition of a universal fact, and as such it rivets mankind'; and he who warned that the monarchy's 'mystery is its life. We must not let in daylight upon magic'.

He was, albeit only briefly, the hero of the world's hopes.

For those who reject it, the Victorian experience is something to feel embarrassed about, to apologise for, to escape from, and never to repeat. But to those who remain enthralled, it is a fabulous story of oustanding success and splendid achievement, by comparison with which Britain's 20th century records seems at best unimpressive, and often distinctly lacklustre.

For all her active goodness, Florence Nightingale herself was far from being the angelic figure of popular adulation: according to Lytton Strachey's Eminent Victorians she was a self-righteous, domineering amazon, who was ruthless in her compassion, merciless in her philantropy, destructive in friendships, obsessional in her list for power, and demonic in her saintliness.
