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.

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.

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.

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'.

More attention should have been given to the fundamental transformation which took place during Queen Victoria's reign, from ruling sovereign to constitutional monarch. Again, gender mattered. If Albert had lived, it seems clear that he would have resisted that development much more tenaciously, which the gradual emasculation (and feminization) of monarchy was probably more easily accomplished when a woman was on the throne.

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.
