“Ridiculous,” said Bristow breathlessly. “You ought to give up detecting and try fantasy writing, Strike. You haven’t got a shred of proof for anything you’re saying—”

“Yes I have.” Strike cut across him, and Bristow stopped talking immediately, his pallor visible through the gloom. “The CCTV footage.”

“That footage shows Jonah Agyeman running from the scene of the killing, as you’ve just acknowledged!”

“There was another man caught on camera.”

“So he had an accomplice—a lookout.”

“I wonder what defending counsel will say is wrong with you, John?” asked Strike softly. “Narcissism? Some kind of God complex? You think you’re completely untouchable, don’t you, a genius who makes the rest of us look like chimps? The second man running from the scene wasn’t Jonah’s accomplice, or his lookout, or a car thief. He wasn’t even black. He was a white man in black gloves. He was you.”

“No,” said Bristow. The one word throbbed with panic; but then, with an almost visible effort, he hitched a contemptuous smile back on to his face. “How can it be me? I was in Chelsea with my mother. She told you so. Tony saw me there. I was in Chelsea.”

“Your mother is a Valium-addicted invalid who was asleep most of that day. You didn’t get back to Chelsea until after you’d killed Lula. I think you went into your mother’s room in the small hours, reset her clock and then woke her up, pretending it was dinnertime. You think you’re a criminal genius, John, but that’s been done a million times before, though rarely with such an easy mark. Your mother hardly knows what day it is, the amount of opiates she’s got in her system.”

“I was in Chelsea all day,” repeated Bristow, his knee jiggling up and down. “All day, except for when I nipped into the office for files.”

“You took a hoodie and gloves out of the flat beneath Lula’s. You’re wearing them in the CCTV footage,” said Strike, ignoring the interruption, “and that was a big mistake. That hoodie was unique. There was only one of them in the world; it had been customized for Deeby Macc by Guy Somé. It could only have come out of the flat beneath Lula’s, so we know that’s where you’d been.”

“You have absolutely no proof,” said Bristow. “I am waiting for proof.”

“Of course you are,” said Strike, simply. “An innocent man wouldn’t be sitting here listening to me. He’d have stormed out by now. But don’t worry. I’ve got proof.”

“You can’t have,” said Bristow hoarsely.

“Motive, means and opportunity, John. You had the lot.

“Let’s start at the beginning. You don’t deny that you went to Lula’s first thing in the morning…”

“No, of course not.”

“…because people saw you there. But I don’t think Lula ever gave you the contract with Somé that you used to get upstairs to see her. I think you’d swiped that at some point previously. Wilson waved you up, and minutes later you were having a shouting match with Lula on her doorstep. You couldn’t pretend that didn’t happen, because the cleaner overheard it. Fortunately for you, Lechsinka’s English is so bad that she confirmed your version of the row: that you were furious that Lula had reunited with her freeloading druggie boyfriend.

“But I think that row was really about Lula’s refusal to give you money. All her sharper friends have told me you had quite the reputation for coveting her fortune, but you must have been particularly desperate for a handout that day, to force your way in and start shouting like that. Had Tony noticed a lack of funds in Conway Oates’s account? Did you need to replace it urgently?”

“Baseless speculation,” said Bristow, his knee still jerking up and down.

“We’ll see whether it’s baseless or not once we get to court,” said Strike.

“I’ve never denied that Lula and I argued.”

“After she refused to hand over a check, and slammed the door in your face, you went back down the stairs, and there was the door to Flat Two standing open. Wilson and the alarm repairman were busy looking at the keypad, and Lechsinka was somewhere in there by then—maybe vacuuming, because that would have helped mask the noise of you creeping into the hall behind the two men.

“It wasn’t that much of a risk, really. If they’d turned and seen you, you could have pretended you’d come in to thank Wilson for letting you up. You crossed the hall while they were busy with the alarm fuse box, and you hid somewhere in that big flat. There’s loads of space. Empty cupboards. Under the bed.”

Bristow was shaking his head in silent denial. Strike continued in the same matter-of-fact tone:

“You must have heard Wilson telling Lechsinka to set the alarm to 1966. Finally, Lechsinka, Wilson and the Securibell guy left, and you had sole possession of the flat. Unfortunately for you, however, Lula had now left the building, so you couldn’t go back upstairs and try and bully her into coughing up.”

“Total fantasy,” said the lawyer. “I never set foot in Flat Two in my life. I left Lula’s and went in to the office to pick up files—”

“From Alison, isn’t that what you said, the first time we went through your movements that day?” asked Strike.

Patches of pink blossomed again up Bristow’s stringy neck. After a small hesitation, he cleared his throat and said:

“I don’t remember whether—I just know that I was very quick; I wanted to get back to my mother.”

“What effect do you think it’s going to have in court, John, when Alison takes the stand and tells the jury how you asked her to lie for you? You played the devastated bereaved brother in front of her, and then asked her out to dinner, and the poor bitch was so delighted to have a chance to look like a desirable female in front of Tony that she agreed. A couple of dates later, you persuaded her to say she saw you at the office on the morning before Lula died. She thought you were just overanxious and paranoid, didn’t she? She believed that you already had a cast-iron alibi from her adored Tony, later in the day. She didn’t think it mattered if she told a little white lie to calm you down.

“But Alison wasn’t there that day, John, to give you any files. Cyprian sent her off to Oxford the moment she got to work, to look for Tony. You became a bit nervous, after Rochelle’s funeral, when you realized I knew all about that, didn’t you?”

“Alison isn’t very bright,” said Bristow slowly, his hands washing themselves in dumb show, and his knee jiggling up and down. “She must have confused the days. She clearly misunderstood me. I never asked her to say she saw me at the office. It’s her word against mine. Maybe she’s trying to revenge herself on me, because we’ve split up.”

Strike laughed.

“Oh, you’re definitely dumped, John. After my assistant rang you this morning to lure you to Rye—”

“Your assistant?”

“Yeah, of course; I didn’t want you around while I searched your mother’s flat, did I? Alison helped us out with the name of the client. I rang her, you see, and told her everything, including the fact that I’ve got proof that Tony’s sleeping with Ursula May, and that you’re about to be arrested for murder. That seemed to convince her that she ought to look for a new boyfriend and a new job. I hope she’s gone to her mother’s place in Sussex—that’s what I told her to do. You’ve been keeping Alison close because you thought she was your fail-safe alibi, and because she’s a conduit to knowing what Tony, whom you fear, is thinking. But lately, I’ve been getting worried that she might outlive her usefulness to you, and fall off something high.”

Bristow tried for another scathing laugh, but the sound was artificial and hollow.

“So it turns out that nobody saw you nip into your office for files that morning,” continued Strike. “You were still hiding out in the middle flat at number eighteen, Kentigern Gardens.”

“I wasn’t there. I was in Chelsea, at my mother’s,” said Bristow.

“I don’t think you were planning to murder Lula at that point,” Strike continued regardless. You probably just had some idea o

f waylaying her again when she came back. Nobody was expecting you at the office that day, because you were supposed to be working from home, to keep your sick mother company. There was a full fridge and you knew how to get in and out without setting off the alarm. You had a clear view of the street, so if Deeby Macc and entourage were to appear, you had plenty of time to get out of there, and walk downstairs with some cock-and-bull story about having been waiting for your sister at her place. The only remote risk was the possibility of deliveries into the flat; but that massive vase of roses arrived without anyone noticing you hiding in there, didn’t it?

“I expect the idea of the murder started to germinate then, all those hours you were alone, in all that luxury. Did you start to imagine how wonderful it would be if Lula, who you were sure was intestate, died? You must’ve known your sick mother would be a much softer touch, especially once you were her only remaining child. And that in itself must have felt great, John, didn’t it? The idea of being the only child, at long last? And never losing out again to a better-looking, more lovable sibling?”

Even in the thickening gloom, he could see Bristow’s jutting teeth, and the intense stare of the weak eyes.

“No matter how much you’ve fawned over your mother, and played the devoted son, you’ve never come first with her, have you? She always loved Charlie most, didn’t she? Everyone did, even Uncle Tony. And the moment Charlie had gone, when you might have expected to be the center of attention at last, what happens? Lula arrives, and everyone starts worrying about Lula, looking after Lula, adoring Lula. Your mother hasn’t even got a picture of you by her deathbed. Just Charlie and Lula. Just the two she loved.”

“Fuck you,” snarled Bristow. “Fuck you, Strike. What do you know about anything, with your whore of a mother? What was it she died of, the clap?”

“Nice,” said Strike, appreciatively. “I was going to ask you whether you looked into my personal life when you were trying to find some patsy to manipulate. I bet you thought I’d be particularly sympathetic to poor bereaved John Bristow, didn’t you, what with my own mother having died young, in suspicious circumstances? You thought you’d be able to play me like a fucking violin…

“But never mind, John. If your defense team can’t find a personality disorder for you, I expect they’ll argue that your upbringing’s to blame. Unloved. Neglected. Overshadowed. Always felt hard done by, haven’t you? I noticed it the first day I met you, when you burst into those moving tears at the memory of Lula being carried up the drive into your home, into your life. Your parents hadn’t even taken you with them to get her, had they? They left you at home like a pet dog, the son who wasn’t enough for them once Charlie had died; the son who was about to come a poor second all over again.”

“I don’t have to listen to this,” whispered Bristow.

“You’re free to leave,” said Strike, watching the place where he could no longer make out eyes in the deepening shadows behind Bristow’s glasses. “Why not leave?”

But the lawyer merely sat there, one knee still jiggling up and down, his hands sliding over each other, waiting to hear Strike’s proof.

“Was it easier the second time?” the detective asked quietly. “Was it easier killing Lula than killing Charlie?”

He saw the pale teeth, bared as Bristow opened his mouth, but no sound came out.

“Tony knows you did it, doesn’t he? All that bullshit about the hard, cruel things he said after Charlie died. Tony was there; he saw you cycling away from the place where you’d pushed Charlie over. Did you dare him to ride close to the edge? I knew Charlie: he couldn’t resist a dare. Tony saw Charlie dead at the bottom of that quarry, and he told your parents that he thought you’d done it, didn’t he? That’s why your father hit him. That’s why your mother fainted. That’s why Tony was thrown out of the house after Charlie died: not because Tony said that your mother had raised delinquents, but because he told her she was raising a psychopath.”

“This is—No,” croaked Bristow. “No!”

“But Tony couldn’t face a family scandal. He kept quiet. Panicked a bit when he heard they were adopting a little girl, though, didn’t he? He called them and tried to stop it happening. He was right to be worried, wasn’t he? I think you’ve always been a bit scared of Tony. What a fucking irony that he backed himself into a corner where he had to give you an alibi for Lula’s murder.”

Bristow said nothing at all. He was breathing very fast.

“Tony needed to pretend he was somewhere, anywhere, other than shacked up in a hotel with Cyprian May’s wife that day, so he said he doubled back to London to go and visit his sick sister. Then he realized that both you and Lula were supposed to have been there at the same time.

“His niece was dead, so she couldn’t contradict him; but he had no choice but to pretend he saw you through the study door, and didn’t talk to you. And you backed him up. Both of you, lying through your teeth, wondering what the other one was up to, but too scared to question each other. I think Tony kept telling himself he’d wait until your mother died before he confronted you. Perhaps that’s how he kept his conscience quiet. But he’s still been worried enough to ask Alison to keep an eye on you. And meanwhile, you’ve been feeding me that bullshit about Lula hugging you, and the touching reconciliation before she returned home.”

“I was there,” said Bristow, in a rasping whisper. “I was in my mother’s flat. If Tony wasn’t there, that’s his affair. You can’t prove I wasn’t.”

“I’m not in the business of proving negatives, John. All I’m saying is, you’ve now lost every alibi except your Valium-addled mother.

“But for the sake of argument, let’s assume that while Lula’s visiting your groggy mother, and Tony’s off fucking Ursula in a hotel somewhere, you’re still hiding out in Flat Two, and starting to think out a much more daring solution to your cash-flow problem. You wait. At some point you put on the black leather gloves that have been left in the wardrobe for Deeby, as a precaution against fingerprints. That looks fishy. Almost as though you’re starting to contemplate violence.

“Finally, in the early afternoon, Lula comes back home, but unfortunately for you—as you no doubt saw through the peephole of the flat—she’s with friends.

“And now,” said Strike, his voice hardening, “I think the case against you starts to become serious. A defense of manslaughter—it was an accident, we tussled a bit and she fell over the balcony—might have held water if you hadn’t stayed downstairs all that time, while you knew she had visitors. A man with nothing worse on his mind than bullying his sister into giving him a large check might, just might, wait until she was alone again; but you’d already tried that and it hadn’t worked. So why not go up there when she was, perhaps, in a better mood, and have a go with the restraining presence of her friends in the next room? Maybe she’d have given you something just to get rid of you?”

Strike could almost feel the waves of fear and hatred emanating from the figure fading into the shadows across the desk.

“But instead,” he said, “you waited. You waited all that evening, having watched her leave the building. You must have been pretty tightly wound by then. You’d had time to formulate a rough plan. You’d been watching the street; you knew exactly who was in the building, and who wasn’t; you’d worked out that there might just be a means of getting clean away, without anyone being the wiser. And let’s not forget—you’d killed before. That makes a difference.”

Bristow made a sharp movement, little more than a jerk; Strike tensed, but Bristow remained stationary, and Strike was acutely aware of the unattached prosthesis merely resting against his leg.

“You were watching out of the window and you saw Lula come home alone, but the paparazzi were still out there. You must have despaired at that point, did you?

“But then, miraculously, as though the universe really did want nothing more than to help John Bristow get what he wanted, they all left. I’m pretty sure that Lula’s regular driver ti

pped them off. He’s a man who’s keen to forge good contacts with the press.

“So now the street’s empty. The moment has arrived. You pulled on Deeby’s hoodie. Big mistake. But you must admit, with all the lucky breaks you got that night, something had to go wrong.

“And then—and I’m going to give you full marks for this, because it puzzled me for a long time—you took a few of those white roses out of their vase, didn’t you? You wiped the ends dry—not quite as thoroughly as you should have done, but pretty well—and you carried them out of Flat Two, leaving the door ajar again, and climbed the stairs to your sister’s flat.

“You didn’t notice that you’d left a few little drops of water from the roses, by the way. Wilson slipped on them, later.

“You got up to Lula’s flat, and you knocked. When she looked through the peephole, what did she see? White roses. She’d been standing on her balcony, with the windows wide open, watching and waiting for her long-lost brother to come down the street, but somehow he seems to have got in without her seeing him! In her excitement, she throws open the door—and you’re in.”

Bristow was completely still. Even his knee had stopped jiggling.

“And you killed her, just the same way you killed Charlie, just the same way you later killed Rochelle: you pushed her, hard and fast—maybe you lifted her—but she was caught by surprise, wasn’t she, just like the others?

“You were yelling at her for not giving you money, for depriving you, just as you’ve always been deprived, haven’t you, John, of your portion of parental love.

“She yelled at you that you wouldn’t get a penny, even if you killed her. As you fought, and you forced her across her sitting room towards that balcony and the drop, she told you she had another brother, a real brother, and that he was on his way, and that she’d made a will in his favor.

“ ‘It’s too late, I’ve already done it!’ she screamed. And you called her a lying fucking bitch, and you threw her down into the street to her death.”
