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.

There are important arguments to be made about the relative merits of an hereditary or an elected head of state: but not at the level of the human frailties of particular monarchs or presidents. No one seriously contends that the American presidency should be abolished because Bill Clinton is a self-confessed adulterer. So why should the abolition of the British monarchy be contemplated because the same is true of Prince Charles?

Vernon Bogdanor's account The Monarchy and the Constitution is written as much in the shadow of Edmund Burke as it is of Walter Bagehot. He stresses the organic development of the British constitution, prefers evolution to revolution, and thinks stability is better than strife.

Prince Charles's concern for the underprivileged and disadvantaged has not exactly endeared him to the Conservative Central Office. As Norman Tebbit replied, it is not surprising that the Prince is so sympathetic towards the unemployed: he is by way of being one of them himself.

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.

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.

Like sex, poverty and power, suicide may always be with us. But like them again, the actual form is takes is essentially time-specific and culture-bound, not only in the past but in the present too. The people who took their lives, the paths which led them to that end, and the experience of dying in this way were deeply influenced by specific historical circumstances. Only by making a greater effort at historical understanding can this most secret house of death be made to yield up more of its confidences.
