made a mistake, feeling so cocky. Whatever the hell this diary was, it was going to ruin me. I could already see the cover of the true-crime novel: the black-and-white photo of us on our wedding day, the blood-red background, the jacket copy: including sixteen pages of never-seen photos and Amy Elliott Dunne’s actual diary entries – a voice from beyond the grave … I’d found it strange and kind of cute, Amy’s guilty pleasures, those cheesy true-crime books I’d discovered here and there around our house. I thought maybe she was loosening up, allowing herself some beach reading.

Nope. She was just studying.

Gilpin pulled over a chair, sat on it backward, and leaned toward me on crossed arms – his movie-cop look. It was almost midnight; it felt later.

‘Tell us about your wife’s illness these past few months,’ he said.

‘Illness? Amy never got sick. Once a year she’d get a cold, maybe.’

Boney picked up the book, turned to a marked page. ‘Last month you made Amy and yourself some drinks, sat on your back porch. She writes here that the drinks were impossibly sweet and describes what she thinks is an allergic reaction: My heart was racing, my tongue was slabbed, stuck to the bottom of my mouth. My legs turned to meat as Nick walked me up the stairs.’ She put a finger down to hold her place in the diary, looked up as if I might not be paying attention. ‘When she woke the next morning: My head ached and my stomach was oily, but weirder, my fingernails were light blue, and when I looked in the mirror, so were my lips. I didn’t pee for two days after. I felt so weak.’

I shook my head in disgust. I’d become attached to Boney; I expected better of her.

‘Is this your wife’s handwriting?’ Boney tilted the book toward me, and I saw deep black ink and Amy’s cursive, jagged as a fever chart.

‘Yes, I think so.’

‘So does our handwriting expert.’

Boney said the words with a certain pride, and I realized: This was the first case these two had ever had that required outside experts, that demanded they get in touch with professionals who did exotic things like analyze handwriting.

‘You know what else we learned, Nick, when we showed this entry to our medical expert?’

‘Poisoning,’ I blurted. Tanner frowned at me: steady.

Boney stuttered for a second; this was not information I was supposed to provide.

‘Yeah, Nick, thank you: antifreeze poisoning,’ she said. ‘Textbook. She’s lucky she survived.’

‘She didn’t survive, because that never happened,’ I said. ‘Like you said, it’s textbook – it’s made up from an Internet search.’

Boney frowned but refused to bite. ‘The diary isn’t a pretty picture of you, Nick,’ she continued, one finger tracing her braid. ‘Abuse – you pushed her around. Stress – you were quick to anger. Sexual relations that bordered on rape. She was very frightened of you at the end there. It’s painful to read. That gun we were wondering about, she says she wanted it because she was afraid of you. Here’s her last entry: This man might kill me. This man might kill me, in her own words.’

My throat clenched. I felt like I might throw up. Fear, mostly, and then a surge of rage. Fucking bitch, fucking bitch, cunt, cunt, cunt.

‘What a smart, convenient note for her to end on,’ I said. Tanner put a hand on mine to hush me.

‘You look like you want to kill her again, right now,’ Boney said.

‘You’ve done nothing but lie to us, Nick,’ Gilpin said. ‘You say you were at the beach that morning. Everyone we talk to says you hate the beach. You say you have no idea what all these purchases are on your maxed-out credit cards. Now we have a shed full of exactly those items, and they have your fingerprints all over them. We have a wife suffering from what sounds like antifreeze poisoning weeks before she disappears. I mean, come on.’ He paused for effect.

‘Anything else of note?’ Tanner asked.

‘We can place you in Hannibal, where your wife’s purse shows up a few days later,’ Boney said. ‘We have a neighbor who overheard you two arguing the night before. A pregnancy you didn’t want. A bar borrowed on your wife’s money that would revert to her in case of a divorce. And of course, of course: a secret girlfriend of more than a year.’

‘We can help you right now, Nick,’ Gilpin said. ‘Once we arrest you, we can’t.’

‘Where did you find the diary? At Nick’s father’s house?’ Tanner asked.

‘Yes,’ Boney said.

Tanner nodded to me: That’s what we didn’t find. ‘Let me guess: anonymous tip.’

Neither cop said a thing.

‘Can I ask where in the house you found it?’ I asked.

‘In the furnace. I know you thought you burned it. It caught fire, but the pilot light was too weak; it got smothered. So only the outer edges burned,’ Gilpin said. ‘Extremely good luck for us.’

The furnace – another inside joke from Amy! She’d always proclaimed amazement at how little I understood the things men are supposed to understand. During our search, I’d even glanced at my dad’s old furnace, with its pipes and wires and spigots, and backed away, intimidated.

‘It wasn’t luck. You were meant to find it,’ I said.

Boney let the left side of her mouth slide into a smile. She leaned back and waited, relaxed as the star of an iced-tea commercial. I gave Tanner an angry nod: Go ahead.

‘Amy Elliott Dunne is alive, and she is framing Nick Dunne for her murder,’ he said. I clasped my hands and sat up straight, tried to do anything that would lend me an air of reason. Boney stared at me. I needed a pipe, eyeglasses I could swiftly remove for effect, a set of encyclopedias at my elbow. I felt giddy. Do not laugh.

Boney frowned. ‘What’s that again?’

‘Amy is alive and very well, and she is framing Nick,’ my proxy repeated.

They exchanged a look, hunched over the table: Can you believe this guy?

‘Why would she do that?’ Gilpin asked, rubbing his eyes.

‘Because she hates him. Obviously. He was a shitty husband.’

Boney looked down at the floor, let out a breath. ‘I’d certainly agree with you there.’

At the same time, Gilpin said: ‘Oh, for Christ’s sake.’

‘Is she crazy, Nick?’ Boney said, leaning in. ‘What you’re talking about, it’s crazy. You hear me? It would have taken, what, six months, a year, to set all this up. She would have had to hate you, to wish you harm – ultimate, serious, horrific harm – for a year. Do you know how hard it is to sustain that kind of hatred for that long?’

She could do it. Amy could do it.

‘Why not just divorce your ass?’ Boney snapped.

‘That wouldn’t appeal to her … sense of justice,’ I replied. Tanner gave me another look.

‘Jesus Christ, Nick, aren’t you tired of all this?’ Gilpin said. ‘We have it in your wife’s own words: I think he may kill me.’

Someone had told them at some point: Use the suspect’s name a lot, it will make him feel comfortable, known. Same idea as in sales.

‘You been in your dad’s house lately, Nick?’ Boney asked. ‘Like on July ninth?’

Fuck. That’s why Amy changed the alarm code. I battled a new wave of disgust at myself: that my wife played me twice. Not only did she dupe me into believing she still loved me, she actually forced me to implicate myself. Wicked, wicked girl. I almost laughed. Good Lord, I hated her, but you had to admire the bitch.

Tanner began: ‘Amy used her clues to force my client to go to these various venues, where she’d left evidence – Hannibal, his father’s house – so he’d incriminate himself. My client and I have brought these clues with us. As a courtesy.’

He pulled out the clues and the love notes, fanned them in front of the cops like a card trick. I sweated while they read them, willing them to look up and tell me all was clear now.

‘Okay. You say Amy hated you so much that she spent months framing you for her murder?’ Boney asked, in the quiet, measured voice of a disappointed parent.

I gave her a blank face.

‘This does not sound like an angry woman, Nick,’ she said. ‘She’s falling all over herself to apologize to you, to suggest that you both start again, to let you know how much she loves you: You are warm – you are my sun. You are brilliant, you are witty.’

‘Oh, for fuck’s sake.’

‘Once again, Nick, an incredibly strange reaction for an innocent man,’ Boney said. ‘Here we are, reading sweet words, maybe your wife’s last words to you, and you actually look angry. I still remember that very first night: Amy’s missing, you come in here, we park you in this very room for forty-five minutes, and you look bored. We watched you on surveillance, you practically fell asleep.’

‘That has nothing to do with anything—’ Tanner started.

‘I was trying to stay calm.’

‘You looked very, very calm,’ Boney said. ‘All along, you’ve acted … inappropriately. Unemotional, flippant.’

‘That’s just how I am, don’t you see? I’m stoic. To a fault. Amy knows this … She complained about it all the time. That I wasn’t sympathetic enough, that I retreated into myself, that I couldn’t handle difficult emotions – sadness, guilt. She knew I’d look suspicious as hell. Jesus fucking Christ! Talk to Hilary Handy, will you? Talk to Tommy O’Hara. I talked to them! They’ll tell you what she’s like.’

‘We have talked to them,’ Gilpin said.

‘And?’

‘Hilary Handy has made two suicide attempts in the years since high school. Tommy O’Hara has been in rehab twice.’

‘Probably because of Amy.’

‘Or because they’re deeply unstable, guilt-ridden human beings,’ Boney said. ‘Let’s go back to the treasure hunt.’

Gilpin read aloud Clue 2 in a deliberate monotone.

You took me here so I could hear you chat

About your boyhood adventures: crummy jeans and visor hat

Screw everyone else, for us they’re all ditched

And let’s sneak a kiss … pretend we just got hitched.

‘You say this was written to force you to go to Hannibal?’ Boney said.

I nodded.

‘It doesn’t say Hannibal anywhere here,’ she said. ‘It doesn’t even imply it.’

‘The visor hat, that’s an old inside joke between us about—’

‘Oh, an inside joke,’ Gilpin said.

‘What about the next clue, the little brown house?’ Boney asked.

‘To go to my dad’s,’ I said.

Boney’s face grew stern again. ‘Nick, your dad’s house is blue.’ She turned to Tanner with rolling eyes: This is what you’re giving me?

‘It sounds to me like you’re making up “inside jokes” in these clues,’ Boney said. ‘I mean, you want to talk about convenient: We find out you’ve been to Hannibal, whaddaya know, this clue secretly means go to Hannibal.’

‘The final present here,’ Tanner said, pulling the box onto the table, ‘is a not-so-subtle hint. Punch and Judy dolls. As you know, I’m sure, Punch kills Judy and her baby. This was discovered by my client. We wanted to make sure you have it.’

Boney pulled the box over, put on latex gloves, and lifted the puppets out. ‘Heavy,’ she said, ‘solid.’ She examined the lace of the woman’s dress, the male’s motley. She picked up the male, examined the thick wooden handle with the finger grooves.

She froze, frowning, the male puppet in her hands. Then she turned the female upside down so the skirt flew up.

‘No handle for this one.’ She turned to me. ‘Did there used to be a handle?’

‘How should I know?’

‘A handle like a two-by-four, very thick and heavy, with built-in grooves to get a really good grip?’ she snapped. ‘A handle like a goddamn club?’

She stared at me and I could tell what she was thinking: You are a gameplayer. You are a sociopath. You are a killer.
