I find myself, with Phoebe in mid-air, wondering about Mrs Kentwell's nipples, and whether they were ever sucked by man or child, and by God one is tempted to imagine her little black-suited cricket of a brother with his soft child's lips sucking at them, snorting and moaning, and Mrs Kentwell's teeth in a glass on the dresser, but I can't stretch to it, and will content myself with more or less established facts.

Jonathon Oakes, Mrs Kentwell's brother, stole letters.

He was twice arrested, but never charged. He followed the postman like a nervous dog, always at a distance, hiding in the gateways, behind hedges, dipping into unknown letterboxes in hope of news. He also had two post office boxes of his own, to which certain private correspondences were addressed.

It is easy enough to understand why he got himself into this state, because Mrs Kentwell ruled the house in Western Avenue with an ivory-handled paper knife on which was engraved the image of an elephant-headed god from India.

On the day in question, Jonathon Oakes was doing his rounds and Mrs Kentwell was taking tea alone in the drawing room. She poured with a steady hand and placed the cup and saucer to her left. She then slit open each of the morning's letters with her paper knife. She removed the stamps and placed them in a neat pile and then removed the contents of each envelope. Those from her friends in England she placed on the top, those from Assam (there were two) were placed underneath. The two local letters were for her brother but she would, as usual, read them before he did (which would not be until she had dealt with matters in Assam and England). He was far too timid a fellow to protest at this high-handedness, but not such a dull one that he would not take his own compensation.

As Alice Kentwell concentrated on parish problems in a village in Kent, her brother was puffing up the hill from his morning's work, anxious to get home before he was soaked by rain. Phoebe, meanwhile, was flying from the roof.

Mrs Kentwell looked up just in time to witness Phoebe's fall. She stood, immediately, substituted paper knife for umbrella and strode out on to the veranda in the style of a woman about to lay low a marauding snake. She tapped the metal point of the umbrella up and down on the wooden floor. She hissed. The naked figure of Phoebe McGrath ran with its rag of a broken arm, while the umbrella played an angry tattoo.

Mrs Kentwell was not astonished. She was beyond astonishment. Western Avenue, she decided, must stand up and fight if it was to remain anything at all.

She stood on the veranda, a tall straight figure in severe black which had begun as mourning for a dead husband and now seemed to represent a different mourning altogether. Mrs Kentwell mourned the lost standards of English civilization which wilted and died in this society of Irish peasants and jumped-up cockneys.

She was still on the veranda, a black sentry with a black umbrella, when yours truly, Herbert Badgery, the ruffian aviator, walked across the roof of the McGrath house and climbed down a fig tree, arranged clothes, and strode out of sight around the north side of the house which had once been known as "Wirralee".

She tapped the umbrella once, a full stop to everything, and returned to her letters whose fine calligraphy danced before her eyes, unravelling before the pull of her anger.

When Phoebe fell from the slippery roof she knew, before she hit the ground, that her life was ruined. As the real world rushed up to meet her, she knew she was not brave enough to be what she would like to be. In mid-air, naked, she wished for death, her chest crushed, her heart pierced, her legs snapped like quail bones. Her feelings were not those of a radical, Bohemian, free-lover, but a seventeen-year-old girl in Geelong who faces social ruin.

When her arm cracked she knew it broken. She leapt to her feet. The light was shining into her mother's window the wrong way, and she could not see Molly, only the reflection of her own nakedness. She was winded.

She heard Mrs Kentwell's umbrella tattoo. They locked eyes a second: the naked girl and the black soldier with the umbrella rifle. She moaned as she ran across the veranda in full sight of two Dodges which were racing fast along Western Avenue. One blew its horn.

Damn them, damn them, damn them all.

Yet before she had closed her bedroom door behind her, a change had come over my beloved who was no longer wishing for death but already making plans for her survival.

It is no struggle to imagine the desperate alibis that came to her -half-formed jelly-like things with no proper legs or faces, desperate creatures that fell to powder when inspected, invisible cloaks with holes in them. They swarmed through the sea of pain as she awaited her mother's inevitable arrival. The arm was useless. She dressed none the less. She bit into her lip to stop the hurt. She had mud on her bottom. She managed to get herself inside a dress, and in all this desperation she was careful to choose a yellow dress that was very similar to the one she had abandoned on the roof.

Inept stories came to her, e. g. she had gone on to the roof to fix a tile; she had taken off her dress to avoid ruining it in the rain; worn no underwear for similar reason.

No, damn it.

When the knock on the door came she was still not ready.

"Come in," she said brightly.

She prepared her face for her mother, opened the door with her good arm, and found not Molly, but me, my face livid with fear, my hands trembling.

"Go away," she hissed, "for God's sake."

I was so pleased to see her in one piece, alive, felt such relief that I was faint and wanted to sit down. I opened my mouth and croaked relief.

"Your buttons are undone. Go away." She pushed at me. She "was more than my equal. She was definitely my superior, for she had, at last, a plan, flimsy, fragile, but one she would make work by the sheer force of her green-eyed will. "I am not in the house," she whispered. "Take them to sit in the parlour at lunchtime andwatch the esplanade."

"Are you all right?"

"Yes, yes, but did you hear me? Then please, I beg you, do what I say."

She closed the door and locked it. I did up my buttons as Jack skidded the Hispano Suiza to a halt and left a new set of skid marks on the bright green lawn.

The morning's drizzle had turned into heavy rain and the wagon driver with his high load of turnips huddled inside the black oilskin while his fox terrier ran along beneath.

The rain bit into her, sweeping across a bay so hateful that anyone could see the town was right to turn its back on it.

"So much the better," she thought, "so much the better for me to run in this, and slip." But when she came around the corner of Martha Street where she had waited for her wet-glassed wrist-watch to bring its hands to one o'clock, the pain was so intense that she almost fainted. She was soaked through and shivering. She stopped and huddled against one of the esplanade's few trees.

At the other end of the avenue a small grey figure with an umbrella battled into the wind.

It was one minute past one. She prayed her audience were assembled in the parlour, that some talk about aeroplanes would not distract them from her fall.

Jonathon Oakes, the Kentwells' brother, beat into the wind with his illicit letters bulging fat inside the pocket of his waistcoat. He did not lift his umbrella. He was nearly home. He would run the bath and read his letters in delicious privacy.

Phoebe seized this chance that fate had thrown up. She waited for the umbrella to come a little closer to her parents' house before she began to run.
