Then the 'session'. She had, she confessed, experienced some flush of excitement as the two silent men (McBryde had only come in later) ogled her as she stripped and posed and donned the see-through lingerie provided, and lay there on the bed in gaping gowns and skimpy negligees. Myton had punctuated her posturings with crude encouragements as gradually she'd felt herself relaxing: 'Christ, that's marvellous! Yeah! Ye-eah! Just hold it there, baby! Keep that hand under your tits and sort of, yes, sort of push 'em at me!' Such manner of talk had excited her and, if she were honest with herself, she'd felt a sort of orgasm of sexual vanity.

Afterwards, when she and Myton were alone, she had asked him to take one or two snaps of her with her own camera – just as a reminder really – and he'd readily done so. He'd still not so much as touched her physically, not yet; but he'd asked her where she was going and said he had his car outside if she wanted a lift anywhere. Before leaving McBryde had given her £100, all in ten-pound notes, which she had placed in her money-wallet; and then Myton had driven her back up to the top of the Banbury Road. She told him that she was thinking of going to the charity pop concert at Blenheim the next evening, 8 July, and then – suddenly – as they were passing the Cotswold House she asked him to stop: she would stay there now. But a white notice – no vacancies – was across the door, and the lady of the house confirmed sadly that the remaining room had just been taken. As she was getting back into the car, she thought she saw a sparrow-hawk flying over towards the huge trees behind her, and she stopped and sought to focus her binoculars upon it. Fatal moment! Myton asked her if she was interested in birdwatching; and she had shown him her list of hoped-for spottings. Well, he knew exactly where she could see the woodpecker – probably see all the woodpeckers. In Wytham! He was interested himself in birds: was a member of the RSPB (this later proving untrue) and had a permit for walking in Wytham Woods (also proving to be untrue).

That was the beginning of all her woe.

Setting off from the semi-circular parking area just before the Great Wood, they had walked diagonally across a field and then along some leafy woodland pathway into a thickly forested area, where she remembered the brittle crackling of dead twigs and branches beneath her feet; and then Myton's hands upon her body. At first perhaps she might have been prepared for some limited petting; but very soon he had grown rough and insistent, and told her that he needed her – urgently. Would have her! He'd stripped off her thin blouse and pulled her to the floor; but she was herself strong and determined in fighting him off. The pocket of the rucksack in which she kept her binoculars – and her knife – was still open; and she managed to struggle away from him and open the blade of the knife – and plunge it into him… It had entered his flesh so easily, like pushing a knife through soft cheese, she said; but a fountain of blood had spurted across the top of her semi-naked body. Unlike the blood though he lay still, utterly still – his eyes wide open and glaring up at her.

She hurled the knife into the trees, picked up her scarlet rucksack, and dressed only in a blood-bespattered skirt she fled the spot in panic – emerging finally into a clearing where, panting and jabbering and whimpering, she ran and ran – she could have no idea how long, how far – before collapsing, and remembering nothing more until she looked up to see a dog, a black and white Welsh Border Collie, and a thick-set, bearded man behind the dog, his face anxious and kindly, looking down at her. A Land-rover was parked a few yards away.

In his cottage David Michaels at first had found it scarcely possible to believe the young woman's extraordinary account of what had occurred. It all seemed like some terrible nightmare, she'd pleaded: of a frenetic struggle and of a sudden death, if death it were; or of a man lying in the agony of death somewhere out there, somewhere in the woods. Indeed were it not for the blood all over her body, it must have been a nightmare surely! The mention of the word 'police' had driven her to hysterical tears; and clearly distressing too was the thought of the car, the car that from his cottage window Michaels could see even then across the lane. But he would deal with things, he'd promised her that – not knowing what he promised. He learned from her of Seckham Villa, and he made his decision. He got her to bath herself, to swallow half a dozen Disprin; and very soon, so suddenly, so miraculously almost, she had fallen deeply asleep, quite naked between the white sheets of his own double bed. And he realized at that moment that he was just as bad as the rest of them, for he lusted after her, just as other men had lusted after her that afternoon.

At Seckham Villa, Michaels had met the three of them – still there: McBryde, Daley, and Hardinge; and he had begun then to appreciate the complexity of the situation in which they all -including Michaels himself – now found themselves. A plan was conceived. And later executed. Just one detail that was new. Karin's intended visit to the pop concert at Blenheim could be used to their ready advantage, since the discovery of the rucksack and other personal possessions somewhere near Blenheim, the day after the concert, would throw everyone on to the wrong scent, and would promote dark suspicions of a young lady missing, presumed dead somewhere, doubtless murdered by some drug-crazed, sex-hyped youth whom she'd met at the jamboree. Fear of exposure and financial ruin was more than sufficient motivation for McBryde; fear of exposure and scandal more than sufficient for Hardinge; and a cheque (neither Karin nor David Michaels knew for how much) sufficient to ensure the co-operation of the mercenary Daley.

That night, back in the cottage on the edge of the woods, Karin had become terrifyingly distraught; he had slept with her, for she wished it so; she had sought throughout that night the reassurance of his embrace, and of his love; and gladly, gloriously, he had met her needs.

It had been her plan, her plea, to go to Wales – away, away somewhere, away anywhere; and the next morning, setting out from Wytham just after 6 o'clock, he had driven there, leaving her in the hands of a kindly woman who must fairly soon (surely, he'd felt) have been in possession of most of the facts herself. The only thing from her rucksack she had taken was £60 – leaving the rest inside her money-wallet: it seemed to them all a convincing detail. From Wales, she had phoned David frequently – sometimes several times each evening. She it was, Karin, who had phoned her mother, together with whom, and with her sisters, the next phase of the plan was conceived: the simple substitution of Katarina's passport, sent to Karin in a plain brown envelope from Barcelona.

Finally, there had been the return to Oxford – and to David Michaels, the man she was learning increasingly to love, and whose solicitude for her, in turn, seemed now to know no bounds. With her hair cut and dyed black, with a pair of black-framed spectacles, she had lived in the cottage in an idyllic state of happiness with David and Bobbie – until a gradual integration into life again: a drink at the village pub, badminton at the village hall, membership of the local operatic society. And marriage! Strange, really, that she could live so happily so near the murder. Yet she could. The nightmare had passed. It was as if a partition existed, a sort of mesh between her and the whole of her life before she'd met David – a mesh like the network of twigs and branches in the spot where the blood had spurted over her.

For the first six months or so David had daily expected to discover the body, especially so as the trees grew bare in that late autumn; or expected others to discover it, as they roamed the ridings and observed the birds, badgers, foxes, squirrels, deer…But no. And when Morse had asked him where he himself might think of hiding a body, it had never occurred to him that Karin could have run so far, so very far from Pasticks out along by the Singing Way.
