The Silkworm

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 scubadived 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 misdemeanors 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 its 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 defense, 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 nonexistent, 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.

Al had brought with him to Selly Oak an offer from Rokeby that could have been made by mail: financial help in starting Strike’s detective business. Al had announced the offer with pride, considering it evidence of his father’s altruism. Strike had been sure that it was no such thing. He suspected that Rokeby or his advisers had been nervous about the one-legged, decorated veteran selling his story. The offer of a gift was supposed to stop his mouth.

Strike had turned down his father’s largesse and then been refused by every single bank to which he applied for a loan. He had called Al back with immense reluctance, refusing to take the money as a gift, turning down a proffered meeting with his father but asking whether he could have a loan. This had evidently caused offense. Rokeby’s lawyer had subsequently pursued Strike for his monthly payments with all the zeal of the most rapacious bank.
