The Silkworm (Cormoran Strike, #2)(101)

We believe the perpetrator to be extremely dangerous, Anstis had said to the reporters, a statement, in Strike’s view, that was both painfully obvious and strangely misleading.

And a memory came to him: the memory of the great adventure of Dave Polworth’s eighteenth birthday.

Polworth was Strike’s very oldest friend; they had known each other since nursery. Through childhood and adolescence Strike had moved away from Cornwall regularly and then returned, the friendship picking up again wherever Strike’s mother and her whims had last interrupted it.

Dave had an uncle who had left for Australia in his teens and was now a multi-millionaire. He had invited his nephew to come and stay for his eighteenth birthday, and to bring a mate.

Across the world the two teenagers had flown; it had been the best adventure of their young lives. They had stayed in Uncle Kevin’s massive beachside house, all glass and shining wood, with a bar in the sitting room; diamond sea spray in a blinding sun and enormous pink prawns on a barbecue skewer; the accents, the beer, more beer, the sort of butterscotch-limbed blondes you never saw in Cornwall and then, on Dave’s actual birthday, the shark.

‘They’re only dangerous if they’re provoked,’ said Uncle Kevin, who liked his scuba diving. ‘No touching, lads, all right? No arsing around.’

But for Dave Polworth, who loved the sea, who surfed, fished and sailed at home, arsing around was a way of life.

A killer born, with its flat dead eyes and its ranks of stiletto teeth, but Strike had witnessed the blacktip’s lazy indifference as they swam over it, awed by its sleek beauty. It would have been content to glide away through the azure gloom, he knew that, but Dave was determined to touch.

He had the scar still: the shark had torn away a tidy chunk of his forearm and he had only partial feeling in his right thumb. It had not affected his ability to do his job: Dave was a civil engineer in Bristol now, and they called him ‘Chum’ in the Victory Inn where he and Strike still met to drink Doom Bar on their visits home. Stubborn, reckless, a thrillseeker to his core, Polworth still scuba-dived in his free time, though he left the basking sharks of the Atlantic well alone.

There was a fine crack on the ceiling over Strike’s bed. He did not think he had ever noticed it before. His eyes followed it as he remembered the shadow on a seabed and a sudden cloud of black blood; the thrashing of Dave’s body in a silent scream.

The killer of Owen Quine was like that blacktip, he thought. There were no frenzied, indiscriminate predators among the suspects in this case. None of them had a known history of violence. There was not, as so often when bodies turned up, a trail of past misdemeanours leading to the door of a suspect, no bloodstained past dragging behind any of them like a bag of offal for hungry hounds. This killer was a rarer, stranger beast: the one who concealed their true nature until sufficiently disturbed. Owen Quine, like Dave Polworth, had recklessly taunted a murderer-in-waiting and unleashed horror upon himself.

Strike had heard the glib assertion many times, that everyone had it in them to kill, but he knew this to be a lie. There were undoubtedly those to whom killing was easy and pleasurable: he had met a few such. Millions had been successfully trained to end others’ lives; he, Strike, was one of them. Humans killed opportunistically, for advantage and in defence, discovering in themselves the capacity for bloodshed when no alternative seemed possible; but there were also people who had drawn up short, even under the most intense pressure, unable to press their advantage, to seize the opportunity, to break the final and greatest taboo.

Strike did not underestimate what it had taken to bind, batter and slice open Owen Quine. The person who had done it had achieved their goal without detection, successfully disposed of the evidence and appeared not to be exhibiting sufficient distress or guilt to alert anyone. All of this argued a dangerous personality, a highly dangerous personality – if disturbed. While they believed themselves to be undetected and unsuspected, there was no danger to anybody around them. But if touched again… touched, perhaps, in the place where Owen Quine had managed to touch them…

‘Fuck,’ murmured Strike, dropping his cigarette hastily into the ashtray beside him; it had burned down to his fingers without him noticing.

So what was he to do next? If the trail away from the crime was practically non-existent, Strike thought, he must pursue the trail towards the crime. If the aftermath of Quine’s death was unnaturally devoid of clues, it was time to look at his last few days of life.

Strike picked up his mobile and sighed deeply, looking at it. Was there, he asked himself, any other way of getting at the first piece of information he sought? He ran through his extensive list of acquaintances in his head, discarding options as quickly as they occurred. Finally, and without much enthusiasm, he concluded that his original choice was most likely to bring him the goods: his half-brother Alexander.

They shared a famous father, but had never lived under the same roof. Al was nine years younger than Strike and was Jonny Rokeby’s legitimate son, which meant that there was virtually no point of coincidence in their lives. Al had been privately educated in Switzerland and he might be anywhere right now: in Rokeby’s LA residence; on a rapper’s yacht; even a white Australian beach, for Rokeby’s third wife was from Sydney.

And yet of his half-siblings on his father’s side, Al had shown himself more willing than any of the others to forge a relationship with his older brother. Strike remembered Al visiting him in hospital after his leg had been blown off; an awkward encounter, but touching in retrospect.
