'True. And what if the place had turned out not to be the one in which you had seen the Temple?�
'I'd have been no worse off than before. I'd have told him that I'd see him in hell sooner than let him have the formula.'
'Yet last night, when he learned that you were still here, and turned on the heat, you gave way again and agreed to meet him tomorrow. Was that because he threatened to put a curse on you if you didn't?'
'Well, partly.'
'If you meant to turn up without the formula, you must have expected that he would curse you just the same. And, as you have had no chance to check up on the interior of the house in Cremorne, you'd have had nothing with which to threaten him. So what did you expect to gain by agreeing to this meeting?�
Khune hesitated a second, then his blue eyes suddenly blazed, and he burst out, 'The chance to kill him and get away with it. The odds against my being able to do so in London were too heavy. But, when he demanded that I should meet him down here, I felt that he was playing into my hands. Out there on the moor, I could have done the job and buried the body in some gully.
In these Welsh hills it would have been ten thousand to one against anyone finding it in my lifetime, and I'd have been free of him for good and all.'
'I see,' Verney nodded. 'Having read your statement it had occurred to me that when you came face to face with him you might be tempted to adopt drastic measures, or even plan them in advance. Would you tell us now why you changed your mind tonight, and decided instead to confide in Forsby?�
The scientist began to twist his long knobbly-knuckled hands together. 'Because a quick death is too good for the swine. He has always loathed discomfort, poor food, ugly clothes, and physical labour. Even more, to be baulked in his ambitions and condemned to a mind-rotting routine, with only common criminals as companions, would be a foretaste of hell for him. I can't get him a long prison sentence; but you can. That is why I'm here instead of thinking out the most painful way to kill him.'
They all recalled the account Khune had given of the break-up of his marriage, and realized how greatly he must have suffered at his brother's hands; yet, even so, the seething hatred with which he spoke left them silent for a minute. Then Verney said:
'It is essential that he should be caught with some document on him that he has received from you, or at least receive such a document within sight of a witness, even if he throws it away afterwards. I take it you are willing to make out a dud formula, go to the rendezvous, and give it to him?'
'Certainly.'
'Good. We shall draw a cordon round the place and, unless we are very unlucky, catch him within a few minutes of his leaving you. I must say, though, I wish you hadn't chosen such an exposed position as this Lone Tree Hill, because it means that, to keep under cover until the meeting has taken place, Forsby's men will have to take up positions a good half mile away.'
Khune shrugged. 'That can't be helped. There are limits to what one can convey on the astral, and it had to be some place that he could easily identify. I had nothing of this kind in mind at the time, but I meant to tell him that up there some birdwatcher might chance to see us through a pair of binoculars; so, before I handed him the paper, it would be best for us to walk down to the wood on the far side of the slope. It was there that I meant to kill him.'
'I'd like you still to carry out that idea as, about fifty yards inside the wood, we could arrange an ambush and he would have much less chance of slipping through our fingers.'
When Khune had agreed, they continued to talk about Lothar for a further quarter of an hour; then it was settled that they should all meet at half past nine next morning and go out to reconnoitre Lone Tree Hill. Forsby accompanied the others out into the avenue and, when they had said good night to Khune outside his bungalow, walked on with the visitors to theirs. As they halted in the doorway, C.B. said:
'Well, Dick, we've had a lucky break. I'm very much happier about this job than when I arrived here this afternoon.'
'So am I.' Forsby nodded. 'In the worst case now, if Lothar does get away, it will be only with a useless bit of paper. All I hope is that he doesn't get wind of what is in the air and fail to turn up.'
'I regard that as much less likely than I did an hour ago. He can't be as sensitive as I feared to what goes on in Otto's mind, otherwise he would have tumbled to it on Thursday night, when Otto agreed to go to London, that he didn't mean to bring the formula with him, and instead had cooked up' an idea for doing him dirt.'
'That's true, Sir,' Barney commented. 'All the same, wouldn't it be best to leave Otto behind when we make our reconnaissance tomorrow? If Lothar took it into his head to have a look at him, and saw him with us selecting hideouts from which to trap him, it's a certainty that he'd call his visit off.'
'Good for you, young feller.' Verney turned to the Squadron-Leader. 'Sullivan's right, Dick. We can't be too careful. Slip along to Otto now. Tell him to try to put tomorrow's business out of his mind before he goes to sleep, and that you are going to reinstall the old tape recorder just in case Lothar comes through to him during the night. And that tomorrow we would like him to remain in his bungalow till lunch time.'
On that, they exchanged good nights and Forsby left them. Tired after their long day, they fell asleep within a few minutes of getting into bed and did not wake until Harlow called them with cups of tea and told them he would be bringing them breakfast in half an hour.
At half past nine Forsby came along to them with the most welcome news that Khune had spent his first untroubled night for nearly a fortnight and that the tape on the recorder remained completely blank. They then set out in Forsby's car on their reconnaissance.
Between the Station and Lone Tree Hill there lay a stretch of wooded high ground, so they did not come in sight of the hill until they were within a mile of it; but then they could see that on three sides it was surrounded by open moorland. Turning off the main road, Forsby drove across the bridge and some way along the track that skirted the base of the hill till he reached a path that wound up it. Getting out, they walked the half mile to its summit, had a good look round, then made their way through the knee-deep heath and young bracken down to the wood.
By eleven o'clock they were on the way back to the Station and had made their plan. Verney was to lie in wait in the wood, with six of the police, and the remainder were to be posted at intervals in two semi-circles round the hill behind such boulders and gorse bushes as offered the best cover. As it seemed obvious that Lothar must arrive by car and would approach the hill from the road, that segment of the circle was, to begin with, to be left open. But Forsby and Barney were to keep the bridge under observation from the wooded rise between the hill and the Station. When they saw Lothar cross the bridge they were to drive down the road in Forsby's car, get out and, with his two rods, start fishing in the stream. By that time Lothar should be sideways on to them and half way up the hill, so could hardly fail to see them. This stratagem they hoped would serve the dual purpose of cutting off his retreat to the road and inducing him readily to accept Otto's suggestion that, before he handed over the paper, they should move down the far side of the hill into the wood, and so be out of sight of the fishermen.
At midday they had some sandwiches in Forsby's bungalow and at half past he went to the police quarters to brief his men. The importance of the affair was impressed upon them and the necessity to remain absolutely still in their cover until they heard two blasts of a whistle. They were then to spring up and, if any running figure was in view, make for it, otherwise to remain stationary. Then were they issued with one round blank and four of ball cartridge apiece, but told that they were not to fire upon the wanted man unless he either threatened them with a weapon or, having broken through the cordon, looked like getting away unless he was brought down.
