Unnatural Causes (22 page)

Half an hour later he settled himself to sleep again. But before he dropped into the first layer of unconsciousness, something happened. He had been thinking drowsily and without effort of Seton’s murder. It had been no more than the mind’s slow recapitulation of the past day. And suddenly, inexplicably, he knew how it could have been done.

It was just after nine o’clock when Dalgliesh got back to Pentlands. The cottage was empty, and for a moment he felt again the foreboding of the night. Then he saw the note on the kitchen table. His aunt had breakfasted early and was walking along the shore towards Sizewell. There was a jug of coffee ready to be reheated and the breakfast table was laid for one. Dalgliesh smiled. This was typical of his aunt. It was her habit to take a morning walk along the beach and it would never occur to her to vary the routine merely because her nephew was flying backwards and forwards between London and Monksmere in chase of a murderer and might wish her to be immediately available to hear his news. Nor would she imagine that a healthy male was incapable of getting his own breakfast. But, as always at Pentlands, the essential comforts were there, the kitchen was warm and welcoming, the coffee strong, and there was a blue bowl of new-laid eggs and a batch of home-baked rolls still warm from the oven. His aunt had obviously been up early. Dalgliesh breakfasted quickly, then decided to stretch his car-cramped legs by walking along the shore to meet her.

He jumped his way down the uneven path of sand and rock which led from Pentlands to the beach. The leaping sea was white capped to the horizon, a brown-grey waste of heaving water, empty of sails and with only the sturdy silhouette of a coaster against the skyline. The tide was coming in fast. Lurching over the stones of the upper beach, he found the ridge of fine shingle which ran halfway between the sea’s edge and the plateau of marram grass which fringed the marshes. Here walking was easier although, from time to time, he was forced to turn his back to the wind and fight for breath. Buffeted and foam-flecked, he squelched onward over the shingle, finding the occasional and welcome stretch of firm, serrated sand and pausing from time to time to watch the smooth green underbelly of the waves as they rose in their last curve before crashing at his feet in a tumult of flying shingle and stinging spray. It was a lonely shore, empty and desolate, like the last fringes of the world. It evoked no memories, cosily nostalgic, of the enchantments of childhood holidays by the sea. Here were no rock pools to explore, no exotic shells, no breakwaters festooned with seaweed, no long stretches of yellow sand sliced by innumerable spades. Here was nothing but sea, sky and marshland, an empty beach with little to mark the miles of outspate shingle but the occasional tangle of tar-splotched driftwood and the rusting spikes of old fortifications. Dalgliesh loved this emptiness, this fusion of sea and sky. But today the place held no peace for him. He saw it suddenly with new eyes, a shore alien, eerie, utterly desolate. The unease of the night before took hold of him and he was glad to see, rising from the sand dunes, the familiar figure of his aunt braced like a flagstaff against the wind, the edges of her red scarf flying.

She saw him almost immediately and came towards him. As they met and stood together, fighting for breath against
a sudden gust of wind, there was a harsh “kraaank” and two heron flew low overhead, pounding the air with heavy, laborious wings. Dalgliesh watched their flight. Their long necks were drawn in, their delicate brown legs stretched straight behind them like a slipstream.

“Heron,” he said with mock triumph.

Jane Dalgliesh laughed and handed him her field glasses. “But what do you make of these?”

A small flock of grey-brown waders was twittering on the edge of the shingle. Before Dalgliesh had time to note more than their white rumps and blackish, down-turned beaks, the birds rose in one swift direct flight and faded into the wind like a wisp of thin white smoke.

“Dunlin?” he hazarded.

“I thought you might say dunlin. They’re very similar. No, those were curlew sandpipers.”

“But the last time you showed me a curlew sandpiper it had pink plumage,” protested Dalgliesh.

“That was last summer. In the autumn they take on the buffish plumage of the young birds. That’s why they look so like the dunlin … Did you have a successful time in London?”

Dalgliesh said: “Most of the day I spent following rather ineffectually in Reckless’s footsteps. But during the course of a too-large lunch with Max Gurney at the Cadaver Club I learned something new. Seton was proposing to use virtually all his capital to endow a literary prize. Having given up hope of personal fame he was proposing to buy a vicarious immortality. He wasn’t skimping the price, either. Incidentally I have an idea now how Seton was killed but as it’s going to be virtually impossible to prove, I don’t think Reckless will thank me for it. I suppose I’d better phone him as soon as we get back.”

He spoke without enthusiasm. Jane Dalgliesh cast a glance at him but asked no questions, and quickly turned her face away in case he should see and be irritated by her obvious concern.

“Did Digby know that he was likely to be done out of his inheritance?” she asked.

“Apparently no one knew except Max. The odd thing is that Seton wrote to him about it and typed the letter himself by the look of it. Yet Reckless didn’t find the carbon at Seton House. He would certainly have mentioned it if he had. And he would certainly have questioned Sylvia Kedge and Digby to find out whether they knew.”

“If Maurice wanted to keep his intention secret, wouldn’t he have typed the letter without taking a carbon?” suggested Miss Dalgliesh.

“He took a carbon, all right. The bottom edge of the carbon got turned in when he put the paper into the machine and the last few words appear on the back of the letter. There’s also a faint smear of carbon on the top edge. He might have decided later to destroy the copy but he was meticulous about his affairs and it doesn’t seem likely. Incidentally, this isn’t the only mystery about carbons. Seton is supposed to have typed that passage about his hero’s visit to the Cortez Club while he was staying in London. But the servant at the Cadaver Club says that there were no carbon copies found in his room. So what happened to them?”

His aunt thought for a moment. This was the first time he had ever discussed a case with her and she was intrigued and a little flattered until she remembered that it wasn’t, of course, his case. Reckless was the one responsible. It was Reckless who would have to decide the significance, if any, of those missing carbons at the Cadaver. But she was surprised at her own interest in the problem. She said: “There are several
possibilities, I suppose. Perhaps Seton didn’t take carbons. In view of his meticulous habits I think that unlikely. Or perhaps he, or someone who had access to his room, destroyed them. Or perhaps the manuscript which Sylvia produced wasn’t the one Seton actually sent her. I expect that Reckless has checked with the postman that a long buff envelope was delivered to her but we’ve only her word that it contained the manuscript. And, if it did, presumably someone who knew that Seton was staying at the club could have substituted one set of papers for another sometime between the sticking down of the envelope and its posting. Or could they? Do we know if Seton put the envelope out for posting where other people could see it? Or did he take it immediately to the post himself?”

“This was one of the things I asked Plant. No one at the Cadaver posted anything for Seton. But the envelope could have been left in his room long enough for someone to get at it. Or he could have handed it to someone else to post. But surely no one could have relied on that? And we know that this wasn’t an unpremeditated killing. At least, I know it. I’ve yet to convince Reckless that it was a killing at all.”

His aunt said: “Isn’t there another possibility? We know that Seton couldn’t have posted the second manuscript, the one describing the body drifting to shore. He was dead by then. And we’ve no reason to suppose that he even wrote it. We’ve only got Sylvia Kedge’s word that it was his work.”

“I think he wrote it,” said Dalgliesh. “When Max Gurney showed me Seton’s letter I recognised the typing. The same man typed the second manuscript.”

As he spoke they were moving instinctively out of the bite of the wind into the shelter of the sunken lane which ran between the sand dunes and the bird sanctuary. Some twenty yards farther on was the third in a series of small observation hides
which overlooked the sanctuary. This particular hide made a natural turning point to their beach walks and Dalgliesh did not need to ask his aunt whether they should go in. To spend ten minutes scanning the reed beds through his aunt’s binoculars and sheltering from the bitter east-coast winds had become one of those rituals which were part of an autumn visit to Monksmere. The hide was typical of its kind, a rough wooden shelter, reed-thatched, with a bench high enough to support tired thighs along the back wall and a slit at eye level giving a wide view over the marshes. In summer it smelt strongly of sun-baked wood, moist earth and lush grasses. Even in the cold months, this warmth lingered, as if all the heat and smells of summer were trapped within its wooden walls.

They had reached the hide and Miss Dalgliesh was about to step first through the narrow entrance when Dalgliesh suddenly said: “No! Wait!”

A minute earlier he had been strolling along almost in a dream. Now, suddenly, his brain awoke to the significance of the signs which his trained senses had subconsciously noted: the single line of male footprints leading from the sand-dusted lane to the hide entrance, a trace on the wind of a sick stench which had nothing to do with the smell of earth or grasses. As his aunt paused he slipped in front of her and stood in the entrance of the hide.

His tall body blocked most of the light from the narrow entrance so that he smelt death before he saw it. The stench of sour vomit, blood and diarrhoea stung his nostrils as if the air of the little hut was saturated with corruption and evil. The smell was not unfamiliar to him but, as always, he had to fight against a momentary and intolerable urge to be sick. Then he bent down, the light streamed in behind him and he saw the body clearly for the first time.

Digby Seton had crawled like a dog into the corner of the hut to die and he had not died easily. The pathetic body, rigid and cold, was huddled along the far wall, the knees drawn up almost to the chin, the head twisted upwards as if the glazed eyes had made one last despairing effort to catch the light. In his agony he had bitten his bottom lip almost in two and a stream of blood, blackened now, had mixed with the vomit which encrusted his chin and the lapels of the once-smart Melton overcoat. He had dug in the earth of the hut with torn and bleeding hands, smearing it over his face and hair and stuffing it even into his mouth as if in a last delirious craving for coolness and water. Six inches from his body lay his hip flask, the top unscrewed.

Dalgliesh heard his aunt’s calm voice. “Who is it, Adam?”

“Digby Seton. No, don’t come in. There’s nothing we can do for him. He’s been dead for twelve hours at least; from some irritant poison by the look of it, poor devil.”

He heard her sigh and she muttered something that he could not catch. Then she said: “Shall I go for Inspector Reckless or would you rather I stayed here?”

“You go, if you will. I’ll keep an eye on this place.” It was possible that he could have saved ten or fifteen minutes by going himself but there was nothing that anyone could do now to help Seton and he had no intention of leaving her alone in this stinking place of death. And she was a fast and strong walker; there would be little time wasted.

She set off at once and he watched her until a turn in the lane hid her from sight. Then he made his way to the top of the sand dunes and found a sheltered hollow in which to sit, his back wedged against a clump of marram grass. From this point of vantage he could keep the hide under observation and could see on his right the whole sweep of the beach and on his
left the sunken lane. From time to time he caught a glimpse of his aunt’s tall striding figure. She seemed to be making excellent time but it would be at least three-quarters of an hour before Reckless and his men, laden with stretcher and their paraphernalia, came into view. There was no spot closer to the beach to bring an ambulance than Pentlands and no shorter way to the hide than by the lane. Burdened with their equipment, they would have a hard time of it against the wind.

Dalgliesh had spent only a few minutes in the hide but every detail was sharp and clear in his mind. He had no doubt that Digby Seton had been murdered. Although he had not searched the body—that was a job for Reckless—nor even touched it except to verify briefly that it was cold and that rigor mortis was well established, he had little doubt that no suicide note would be found. Digby Seton, that facile, uncomplicated, rather stupid young man, as pleased with his fortune as a child with a new toy and full of happy plans for bigger and brighter nightclubs, was hardly a likely suicide risk. And even Digby had sense enough to know that there were easier ways of dying than to have one’s stomach and guts burnt away with poison. There had been no bottle near the body except the hip flask. Almost certainly that had contained the stuff. The dose must have been very large. Dalgliesh’s mind ranged over the possibilities. Arsenic? Antimony? Mercury? Lead? All could produce those signs. But this was mere speculation. In time the pathologists would have all the answers: the name of the poison, the dose, the time it had taken for Seton to die. And the rest would be for Reckless.

But assuming that the stuff had been put in the hip flask, who was a likely suspect? Someone who had access both to the poison and the flask. That was obvious. Someone who knew the victim well; knew that Digby, alone and bored, wouldn’t be able to resist taking a pull at the flask before
facing the bitter wind and the long walk home. And that implied someone who could persuade him to a rendezvous at the hide. Why else should he have gone there? No one at Monksmere had ever known Digby Seton to be interested in birdwatching or in walking. And he had not been dressed for either activity. Nor had he carried binoculars. This was murder all right. Even Reckless would hardly suggest that Digby Seton had died naturally or that someone with a perverted sense of humour had put his corpse in the hide with the object of inconveniencing Adam Dalgliesh and his aunt.
