And Moggit wasn't all. There were two of Carol's father's favourite pigeons, too, hanging limp from other branches with their wings twisted all askew. And a hedgehog still alive but with a rusty iron spike through its side, pinning it to the ground; so that it staggered dizzily round and around on its own axis in unending agony, snuffling horribly. Yes, and there were other things, too, but Carol didn't want to see any more.

Johnny, satisfied that no one was there, had returned to his 'game'. Through eyes that were brimming with tears, Carol saw him stand up, catch a dead pigeon in one hand and thrust his stick right through its clay-cold body. And he worked the stick in its unfeeling flesh almost as if ... as if it wasn't unfeeling at all! As if he really believed that the bedraggled, stiff, broken thing could feel it. And all the while he laughed and talked and muttered to these poor, tortured, alive or dead or soon-to-be-dead creatures, caring nothing for their waking or sleeping agonies. Indeed, his sister now understood something of the nature of his game: that having harried a living thing to its death, Johnny couldn't bear that it had escaped him and so continued to torture it in the lightless world beyond!

And at that she was the first to know the truth about her adopted brother, without even knowing she knew it. For, a child herself, she recognized a child's fancy when she saw one, knew also that Johnny was simply a cruel and hateful boy, and that what she'd imagined just couldn't be.

But Moggit, poor Moggit! Finally it got through to Carol that it was indeed her battered, half-eviscerated cat which Johnny was slowly hanging. And she could bear it no longer.

'MoggHW she screamed at the top of her voice. And: 'Johnny, I hate you - oh, how I hate you!'

She stood up, stumbled and regained her balance, flew at him clutching the jagged half of a brick. Johnny finally saw her and his red-blotched face rapidly turned pale. He snatched up his penknife - not to use on her but with an entirely different, perhaps even worse purpose in mind -and went to slice through a length of tough kite-string which held down Moggit's branch. Strands parted but the string didn't; in a sudden rage Johnny jerked the string this way and that, and Moggit was lifted and whirled like a rag, his hoarse cat cries cut off as the wire bit into his rubbed-raw throat.

Then Johnny gave a gasp of triumph as his knife cut through the string, and Moggit was jerked aloft, choking and spitting for a second or two as the noose tightened to finish the job. But Johnny was so intent on the murder of the cat that Carol was on him. Blindly, whirling her arms, she came at him with the sharp nails of one hand and the half-brick grasped tight in the other. He avoided her raking nails, but a sharp, broken corner of the brick struck him on the forehead and knocked him down. In a moment he was sitting up, shaking his head, looking around for his knife. And his eyes blazed as he glared at his sister and threatened, 'First Moggit, and now you!'

He got unsteadily to his feet, his forehead grazed and bleeding, then spotted his penknife and pounced on it. And in that same moment Carol knew she was in deadly danger. Johnny couldn't let her tell her parents what she had seen, what he had done. And there was only one way he could be sure to stop her.

With a backward glance that took in the whole scene one last time - poor Moggit hanged and bobbing with the motion of the elder branch, the hedgehog finally exhausted, gasping its life out where it lay, and the dead, mutilated birds strung up in a row - she turned away and fled for home. And bursting through the tunnel of undergrowth out of the ruins, she knew that Johnny was right behind her.

And he would have been; except he knew that if she got home first, she would bring someone to see. And he mustn't let anyone see.

Quickly he cut down Moggit and the birds, and yanked the hedgehog's stake from the ground. Panting from the furious pace of his exertions, and from his fury in general, he tossed the lot into a deep, stagnant well which he'd discovered on the site, whose battened cover had long since rotted away in one corner. He hated to see his dead and dying things go down into the dark like that, making splashes in the deep, black, unseen water below. Wasted, all of them, and so much 'life' still left in them! It was all Carol's fault. Yes, and there'd be a lot more to blame her for if she got home first.

He set out after her, following her wailing and the wild, zig-zag, trail she left through the long grass.

A half-mile across rough, open countryside is a long way when you're a heartbroken child with your eyes full of tears. Carol's heart hammered in her breast and her breath was ragged and panting; but to drive her on there was always that picture burning on her mind's eye, of Moggit dangling and jerking in the wire noose, with his guts hanging out like a small bag of crushed fruits when her mother made jam in the kitchen. And to drive her even faster was Johnny's voice crying after her: 'Caaarol! Carol - wait for me!'

She did no such thing; the garden wall was just ahead, at the end of the hedgerow; behind her, panting - and yet growling too, like some savage dog - Johnny was catching up. His groping hand missed her ankle by inches as she half-climbed, half-fell over the wall. But on the garden side she just lay there, too terrified, tearful, too exhausted to go on.

And Johnny jumping down after her, his eyes mad and glaring, small fists tightening and slackening where he held them to his sides. She looked toward the house but it was hidden behind fruit trees and the misted dome of the pool. Would her parents be up yet? She didn't even have the wind for yelling.

Johnny snarled as he bunched her hair in a strong fist and commenced dragging her towards the pool. 'Swimming!' he said, the word bursting from his lips like a bubble of slime. 'You're going swimming, Carol. You're going to like it, I know. And so am I. Especially afterwards!'

For the last week or so, David Prescott had also taken to getting up early. Alice didn't complain or ask why, because he was always so quiet and considerate and invariably brought her a cup of coffee. It must be the summer, the light mornings, the old 'early bird' syndrome. But in fact it was the mail.

Out this way the mail deliveries were always early, the very crack of dawn, and David was expecting a letter. From the orphanage. Not that it would contain anything of any significance - he was sure it wouldn't - but still he'd like to get to it before Alice. If she saw it first... well, she'd only say he was paranoid. About Johnny. And certainly it would look as though he was, else why would he write to the orphanage about him?

The thing was, David was desperate that things should work out all right; he really did want to love the poor kid. But at the same time he'd always been more receptive of mood than Alice - more aware of the aura of people, especially kids - and he knew that Johnny's aura just wasn't right. If it was something out of his past (but what past? He was just a child), something the orphanage would know about, then David believed that he and his wife should be told. For he suspected Alice was right to complain about the attitude of the orphanage; they had seemed too eager to wash their hands of Johnny, or rather: 'To place him in the care of a normal, loving family, where he can grow into a healthy person. Healthy in mind, as well as in body...'

That's what the orphanage director had said the day they went to pick up their new son, and the words had always stuck in David's memory: 'Healthy in mind, as well as in body.'

Something wrong with Johnny's mind? Something a little sick? Or a lot sick? For that was the nature of the aura which David sometimes felt washing out from the boy: a sick one, and clammy as an old man on his deathbed. Johnny felt sick as death. But not his death.
