As author in control of the plot I can choose and dictate the fall-out of events from any number of infinite possibilities -- which is a very volatile state of affairs, suggesting the ephemerality of fictional narrative. I can choose to have seven characters and kill six of them off in the first five minutes. I can have seventy characters and squash them under a fallen rock, make them copulate with beasts, sit them on the moon or turn their hair white. This casual condition of authorship is irresponsible.

The start of a film is like a gateway, a formal entrance-point. The first three minutes of a film make great demands on an audience's patience and credulity. A great deal has to be learnt very rapidly about place and attitude, character and intent and ambition.

I invariably, after great familiarity with a film, concoct a personal way of reading it that relies entirely on information which a public audience would, I feel, have scant interest. I might travel from a casual unrehearsed glance of a minor character to a detail of folded cloth, from a rhyme in the dialogue to an over-excited high note in the music, from a misplaced shadow to a patch of rogue colour, from a shine on a furniture leg to a curious accidental photographic haze around a street lamp, from the examination of a cloud that looks like a snail to the discomfort of an actress who I know is stifling a sneeze.

A final word. Drowning by Numbers is a story of three women who murder their husbands -- one in a bath, one in the sea and one in a swimming pool. It is a black and ironic fairy-tale for adults, half invented by children who are innocently obsessed with sex and death -- especially death. It is a poetic, amoral tale told morally to support the belief that the good are seldom rewarded, the bad go largely unpunished and the innocent are always abused.

Two children die. An accident and a suicide amongst so many murders. A chance death and a death of self-recrimination. Smut and the Skipping Girl have been aping their parents and elders -- perhaps they could now teach them a lesson -- all the machinations and game-playing and adjusting for sexual and emotional positioning is not worth the effort.

As for the girl -- the child of a prostitute -- what of her future? A life of prostitution in a gaudy dress -- pretending to be Nell Gwynne, the Protestant whore? No -- out of her mother's earnings she will go to University and study to become an astronomer. Charles II made his mistress Nell Gwynne an honorary member of the Royal Astronomical Society in 1674.

There is no obligation for the author of a film to believe in, or to sympathise with, the moral behaviour of his characters. Nor is he necessarily to be accredited with the same opinions as his characters. Nor is it necessary or obligatory for him to believe in the tenet of his construction -- all of which is a disclaimer to the notion that the author of Drowning by Numbers believes that all men are weak, enfeebled, loutish, boorish and generally inadequate and incompetent as partners for women. But it's a thought.

Counting makes even hideous events bearable as simply more of the same -- the counting of wedding-rings, spectacles, teeth and bodies disassociates them from their context -- to make the ultimate obscene blasphemy of bureaucratic insensitivity. Engage the mind with numbing recitation to make it empty of reaction.

Human relationships are patterned and cross-patterned and restricted and limited and de-limited and caged and freed again by the elaborate conventions, rules, and games we call Civilisation … the rules and the games are often absurd and farcical -- sometimes they are tragic -- yet we tacitly acknowledge that they are necessary.
