He had thought carefully before he spoke, knowing that it might be a mistake. It was a mistake. The warning, however carefully phrased, had sparked off that latent antagonism of which he was uneasily aware in all his dealings with Rickards.
Rickards said: 'What you mean, Mr Dalgliesh, is that it might not be easy for her. I've already spoken to the lady and I know something about her past. It took a lot of courage to stand up for her principles as she did. Some might say a lot of obstinacy. A woman who is capable of that has guts enough for anything, wouldn't you say?'
Dalgliesh watched the car lights until Rickards reached the coastal road and turned right, then locked the door and began a desultory tidying-up before bed. Looking back over the evening he recognized that he had been reluctant to talk to Rickards at length about his Friday morning visit to Larksoken Power Station and less than open about his reactions, perhaps because they had been more complex and the place itself more impressive than he had expected. He had been asked to arrive by 8.45 since Mair wanted to escort him personally and had to leave for a luncheon appointment in London. At the beginning of the visit he had asked: 'How much do you know about nuclear power?'
'Very little. Perhaps it might be wiser to assume that I know nothing.'
'In that case we'd better begin with the usual preamble about sources of radiation, and what is meant by nuclear power, nuclear energy and atomic energy, before we begin our tour of the plant. I've asked Miles Lessingham as Operations Superintendent to join us.'
It was the beginning of an extraordinary two hours. Dalgliesh, escorted by his two mentors, was garbed in protective clothing, divested of it, checked for radioactivity, subjected to an almost constant stream of facts and figures. He was aware, even coming as an outsider, that the station was run with exceptional efficiency, that a quietly competent and respected authority was in control. Alex Mair, ostensibly there to escort a man afforded the status of a distinguished visitor, was never uninvolved, always quietly watchful, obviously in charge. And the staff Dalgliesh met impressed him with their dedication as they patiently explained their jobs in terms which an intelligent layman could understand. He sensed beneath their professionalism a commitment to nuclear power amounting in some cases to a controlled enthusiasm combined with a defensiveness which was probably natural given the public's ambivalence about nuclear energy. When one of the engineers said: 'It's a dangerous technology but we need it and we can manage it', he heard, not the arrogance of scientific certainty but a reverence for the element which they controlled, almost the love-hate relationship of a sailor for the sea which was both a respected enemy and his natural habitat. If the tour had been designed to reassure, then it had to some extent succeeded. If nuclear power was safe in any hands then it would be safe in these. But how safe, and for how long?
He had stood in the great turbine hall, ears pulsating, while Mair produced his facts and figures about pressures, voltages and breaking capacity; had stood, garbed in protective clothing, and looked down where the spent elements lay like sinister fishes underwater in the fuel cooling pond for a hundred days before being dispatched to Sellafield for reprocessing; had walked to the edge of the sea to look at the cooling water plant and condensers. But the most interesting part of the visit had been in the reactor house. Mair, summoned by a bleep from his intercom, had temporarily left them and Dalgliesh was alone with Lessingham. They had stood on a high walkway looking down at the black charge floors of the two reactors. To one side of the reactor was one of the two immense fuelling machines. Remembering Toby Gledhill, Dalgliesh glanced at his companion. Lessingham's face was taut and so white that Dalgliesh feared that he was about to faint. Then he spoke almost like an automaton, reciting a lesson learned by rote.
'There are 26,488 fuel elements in each reactor and they're charged by the fuelling machinery over a period of five to ten years. Each of the fuelling machines is approximately 23 feet high and weighs 115 tons. It can hold 14 fuel elements as well as the other components which are necessary for the refuelling cycle. The pressure vessel is heavily shielded, with cast-iron and densified wood. What you see mounted on top of the machine is the hoist unit for lifting the fuel elements. There is also a connecting unit which couples the machine to the reactor and a television camera which allows viewing of the operations above the magazine.'
He broke off and, looking at him, Dalgliesh saw that the hands gripping the rail in front of him were shaking. Neither spoke. The spasm lasted less than ten seconds. Then Lessingham said: 'Shock is an odd phenomenon. I dreamed of watching Toby fall for weeks afterwards. Then the dream suddenly stopped. I thought I'd be able to look down at the reactor charge floor and put the image out of my mind. Most of the time I can. After all, I work here, this is my place. But the dream still recurs and sometimes, like now, I can see him lying there so clearly that it could be a hallucination.'
Dalgliesh felt that nothing he could say would be other than banal. Lessingham went on: 'I got to him first. He was lying prone but I couldn't turn him over. I couldn't make myself touch him. But I didn't need to. I knew that he was dead. He looked very small, disjointed, a rag doll. All I was aware of were those ridiculous symbols of a yellow bee on the heels of his trainers. Christ, was I glad to get rid of those bloody shoes.'
So Gledhill hadn't been wearing protective clothing. The impulse to suicide hadn't been completely spontaneous.
Dalgliesh said: 'He must have been a good climber.' 'Oh yes, Toby could climb. That was the least of his talents.'
And then, without a perceptible change in his voice, he continued with the description of the reactor and the procedure for loading new fuel into the reactor core. Five minutes later, Mair rejoined them. On their way back to his office at the end of the tour he had suddenly asked: 'Have you heard of Richard Feynman?'
'The American physicist? I saw a television programme about him a few months ago, otherwise the name wouldn't have meant anything to me.'
'Feynman said: "Far more marvellous is the truth than any artist of the past imagined. Why do poets of the present not speak of it?" You're a poet, but this place, the power it generates, the beauty of the engineering, the sheer magnificence of it, it doesn't particularly interest you, does it? You or any other poet?'
'It interests me. That doesn't mean that I can make poetry out of it.'
'No, your subjects are more predictable, aren't they? How does it go?
Twenty per cent to God and to His saints,
Twenty per cent to nature and her proxies.
And all the rest devoted to the plaints
Of guys pursued by or pursuing doxies.'
Dalgliesh said: 'The percentage for God and His saints is down but I'd agree that the doxies are more than holding their own.'
'And that poor devil out there, the Norfolk Whistler, he's not poetic either presumably.'
'He's human. That makes him a fit subject for poetry.'
'But not one you'd choose?'
Dalgliesh could have replied that a poet doesn't choose his subject, it chooses him. But one reason for escaping to Norfolk had been to avoid discussions about poetry and even if he had enjoyed talking about his writing, it wouldn't have been with Alex Mair. But he had been surprised how little he had resented the questions. It was difficult to like the man, impossible not to respect him. And if he had murdered Hilary Robarts then Rickards was faced with a formidable opponent.
