On several occasions, we are informed that the professional ideal 'took steps', 'organised assaults', and 'selected social problems'. But this is anthropomorphic metaphor implausibly masquerading as historical explanation.

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.

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'.

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.

In the early 21st century, it is easy to condemn the Bond books for being racist and imperialist, sexist and misogynist, elitist and sadistic. But this is merely another way of saying that we cannot understand the Bond books without reference to the personality, the outlook and the 'Tory imagination' of the man who wrote them, and to the time in which he wrote them; and that we cannot understand the 1950s and 1960s without some reference to them, and to him.

It is impossible not to be moved by the verve, courage and elan with Churchill attacked his last and ultimately invincible enemy, old age and infirmity. As in all his campaigns, he assailed his adversary with endless high spirits, expert advice, ample helpings of brandy and champagne, and the loving and long-suffering support of his wife.

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.
