He grinned and put a hand on my knee. I pretended it wasn’t there and eventually he moved it to change gear.

‘I’ll bet it was,’ he said. ‘I’ve met them, remember? How Greg came from a family like that I’ll never know. At least you’ve done your duty.’

‘I took them books they didn’t want, photos they gave back, and memories they were trying to erase. We all hated every minute of it.’

‘What are you doing later?’

‘This and that.’

‘Are you working?’

‘A little,’ I said evasively.

‘Good. You need to get back to things, Ellie.’

‘You’re probably right.’

‘You look a bit tired. Have you been okay?’

‘Some days are better than others.’

‘If you ever want someone to talk to…’

‘I’ve talked enough. I just go over and over the same things. There’s nothing left to say that I haven’t said already.’

‘Are you all right for money?’

‘What?’

‘Money,’ he repeated. ‘Are you all right?’

‘Fine, I think. As far as I know. I haven’t gone through everything. I’ve let things slide. Greg and I weren’t big savers, but we didn’t spend much either.’

‘I can give you some. Lend,’ he corrected himself hastily. ‘If there’s a cash-flow problem.’

‘That’s good of you. But I’ll be all right.’

The car pulled up outside my house. I went to kiss his cheek but he turned his face and, before I had a chance to pull away, kissed me on the lips. I pushed him away. ‘What do you think you’re doing?’

‘I’m kissing you.’

‘Don’t be ridiculous. You’re my friend. And you were Greg’s friend. And you’re married to Alison. Who knows what you get up to behind her back? But not with me.’

‘Sorry, sorry, sorry,’ he said, with a groan that was also a half-laugh. ‘I don’t know what came over me. You’re a lovely woman.’

‘Do you pounce on every lovely woman?’

He held up his hands in mock-surrender, trying to make it into a joke. ‘Just the ones I can’t resist.’

‘Poor Alison,’ I said, and saw a flash of anger cross his face.

‘Alison’s fine. We have a good marriage.’

‘I’m going to forget it happened,’ I said. ‘Don’t ever do that again.’

‘I won’t. Sorry, sweetheart.’

I looked at him as if he were a strange, exotic specimen I’d observed. ‘Is it easy?’

‘What?’

‘To have an affair and then go home at night.’

‘You make it sound as if I do it all the time.’

‘Do you?’

‘Of course not! You know me.’

‘What about at the moment? Is there anyone?’

‘No!’ But something in his voice, in his expression, told me he was lying.

‘Come on, Joe – who?’

‘No one.’

‘I know there is. Is she married?’

‘You’ve got a one-track mind. Ever since Greg died, you’ve been on the look-out for adultery and deception.’

‘Someone from work? Someone I know? It is, isn’t it?’

‘Ellie.’ He was half laughing, as if this was a great joke.

‘Oh, God, I know who it is.’

‘This is ridiculous. I don’t know what you’re on about.’

‘It’s Tania, isn’t it?’

‘No!’

‘Joe?’

‘It’s nothing, I promise. But she’s so young and eager.’

‘Oh God, Joe,’ I said. I felt anger well inside me as I gazed at his handsome, rugged face, his smiling mouth. ‘She’s half your age.’

‘Maybe that’s the point, Ellie,’ he said. ‘And maybe you should stop judging everyone.’

‘I don’t.’

‘You do, and I understand why.’

‘I don’t mean to. I just can’t bear to think of Alison getting hurt.’

‘She won’t, I promise. And that – just now -’ he gestured round the car as if the kiss was still floating in the air ‘- that was wrong of me. Greg’s death has left me feeling at a loss. Forgive me.’

After he had driven away I entered my house, but only to dump the shopping bag of Greg’s effects I’d brought back from his parents. Then I walked to the Underground station, eyes watering in the easterly wind. In spite of everything I made up my mind to go back to Party Animals, and I couldn’t bear to wait, even though I wasn’t sure what I would do there, except more snooping.

The first train was thirteen minutes away, and I wanted to weep with impatience. I paced up and down the platform. I had three new pieces to add to Life’s Most Difficult Jigsaw Puzzle: Milena had been having an affair with Frances’s husband; Johnny had been with Milena on the one night when I had evidence to show that she was with Greg; the menu card with Milena’s note written to Greg and finally discovered by Fergus tucked inside a book was therefore…

I stopped, my brain hurting with the effort of holding together all the information that wanted to fly in different directions. Therefore what? Therefore a typo, a tease, a slip of the pen, a red herring, a mistake, a contradiction, a fraud, a mystery – something manufactured to drive me mad.

I rang the bell, and when Frances didn’t answer the door, let myself in with the key I still had. I called from the top of the stairs. The basement light was on. I knew Beth was away on holiday, so I thought that Frances was probably about, but there was no answer. I went down, wriggling out of my coat as I did so, pulling off my scarf, tossing them both over the easy chair as I came into the room.

Frances had obviously been there earlier and was expecting to return. The radiator was warm, the Anglepoise lamp over her desk was turned on, although the rest of the room was in shadow, and there was a mug beside her computer, as well as her glasses and several glossy holiday brochures with exotic destinations.

I prowled restlessly round the office, pulling random books off the shelves. I opened the drawers of Frances’s desk and peered inside: a drawer for receipts, one for stationery, another for an assortment of old menus, leaflets and empty bottles. I felt more than usually uneasy now that I knew David had had an affair with Milena, and Frances had had an affair with – with who? The ghastly suspicions I had were eating away at me, although I knew I was probably being ridiculous. Frances, with a husband who cheated on her under her nose with her business partner, and a woman she thought of as a friend who had snuck in under false pretences, gained her confidence, and now spent her time digging out her most intimate secrets.

Eventually I sat down at Milena’s large desk, switched on the side lamp, and turned on her computer, drumming my fingers on the keyboard as I waited for it to boot up. It was very quiet. I could hear the radiators hum and the wind blow against the glass. Every so often, a car passed or a door slammed, far off. It was quite dark outside now, and the room was dim apart from the two pools of light cast by the lamps. I had a sudden overwhelming urge to be back in my down-at-heel little house – not on my own, though; not in the lonely here and now. I wanted to be there with Greg, blinds drawn, the kettle boiling, him singing loudly and tunelessly and asking what we should eat for supper, reading out crossword clues that neither of us ever got, putting his arms round me from behind and resting his chin on the top of my head. My world of safety, no matter how scary it was outside.

I shivered and concentrated on the screen, typing in Milena’s password, accessing once more her hectic private life. I heard footsteps on the pavement drawing nearer, then receding. A dog barked. I clicked once more on the messages from David and stared at them, as if some secret was hidden between the lines.

‘Oh, God, Greg,’ I said out loud, and leaned forward, rolling the chair a bit closer to the desk and resting my head on my arms. My foot touched something solid. I sat up and pushed the chair back again. I bent down, just a little, to see what was there.

A boot, lying lengthways, but a boot wasn’t heavy, was it? Two boots, black with elegant pointed toes and small, sharp heels. The room shifted around me; the walls seemed to close in. There was a sour taste in my mouth. I bent down further. I heard a gasp, and it had come from me but it didn’t sound like me. I stood up, the floor tipping beneath me, sweat prickling on my forehead, and held on to the desk to steady myself. Then I saw. Her body lay bundled under the desk, but her head stuck out, and her eyes were looking up at me. I staggered back, my hand over my mouth. I closed my eyes, but when I opened them again, she was still there: how could I have missed seeing her until now?
