And, with luck, the smug little shit would end up with a lot of bright yellow yolk all over his face on his very first job. How sweet that would be.

He stared at the entryphone panel and felt butterflies in his stomach. Get a grip, man! Standing here on a doorstep like a pathetic teenager! At half past bloody eleven on a Sunday night!

He felt tired suddenly. Drained. For a moment anger flared up inside him – anger at Cleo and at himself for being so weak in coming here – and he was tempted to go back to his car and drive home. He turned, felt in his pocket for his keys, and was in the process of pulling them out when he heard her voice, sounding strangely distorted through the speakerphone. ‘Hi!’

And that voice did something to him. It totally energized him. ‘Pizza!’ he said in a bad Italian accent. ‘You have-a-order-a pizza?’

She laughed. ‘Come into the courtyard and turn right. Number six, far end on the left! I hope you didn’t forget the extra anchovies!’

The lock opened with a sharp click. He pushed the heavy gate open, digging in his pocket, suddenly remembering his chewing gum, and popped a stick in his mouth, as he walked across the spotless cobblestones illuminated by a row of lights inside glass domes. As he reached her door he put the gum back in its foil wrapper and balled it into his pocket.

The door opened before he had even pressed the bell, and Cleo stood there, barefoot, in tight jeans and a loose blue sweatshirt, some of her hair clipped up, the rest loose. Her face was pale, she was wearing hardly any make-up, yet she looked more beautiful than ever.

She greeted him with a meek smile, and a round-eyed guilty sort of look, like a child who has done something just a little bit naughty. ‘Hi!’ she said, and gave a little shrug.

Grace shrugged back. ‘Hi.’

There was an awkward silence, as if each of them was waiting for the other to offer a kiss. Neither did. She stepped aside for him to come in, then closed the door behind him.

He entered a large, open-plan living room, softly lit with a dozen or more small white candles and some hip, ultra-modern lights; there was a strong scent in the room, faintly sweet, musky, feminine and very seductive.

The room had a good vibe; he felt instantly relaxed, could feel it was every inch Cleo. Cream walls and throw rugs on a polished oak floor, two red sofas, black-lacquered furniture, funky abstract paintings, an expensive-looking television and a Latino song from El Divo playing quietly, but assertively, from four seriously cool-looking black speakers.

There were several lush green plants, and in a square glass fish tank on the coffee table, a solitary goldfish was swimming around through the remains of a submerged miniature Greek temple.

‘Still up for a whisky?’ Cleo asked.

‘I think I need one.’

‘Ice?’

‘Lots.’

‘Water?’

‘Just a splash.’

He walked over to the tank.

‘That’s Fish,’ she said. ‘Fish, meet Detective Superintendent Roy Grace.’

‘Hi, Fish,’ he said, then turning to Cleo, added, ‘I have a goldfish, too.’

‘I remember, you told me. Marlon, right?’

‘Good memory.’

‘Uh huh. It’s better than a goldfish’s. I read that they can only remember things for twelve seconds. I can sometimes remember things for a whole day.’

Grace laughed. But it was forced laughter. The atmosphere between them was strained, like two boxers in a ring, waiting for the bell for the first round to clang.

Cleo went out of the room, and Grace took the opportunity to take a closer look round. He walked over to a framed photograph which shared a small side table with a rubber plant. It showed a handsome, distinguished-looking man in his early fifties, dressed in top hat and tails, next to a fine-looking woman in her mid to late forties, who bore a striking resemblance to Cleo, in a stunningly elegant outfit and a large hat; there were dozens of people similarly attired in the background. Grace wondered if it was the Royal Enclosure at Ascot, although he had never been there.

Then he wandered over to a floor-to-ceiling stack of crammed bookshelves. He picked out a row of Graham Greene novels, a set of Samuel Pepys diaries, several crime novels, from Val McDermid, Simon Brett, Ian Rankin and Mark Timlin, a Jeanette Winterson, two James Herbert novels, an Alice Seebold, a Jonathan Franzen, The Corrections, a row of Tom Wolfe, bios of Maggie Thatcher and Clinton, a eclectic mixture of chick lit, an ancient copy of Gray’s Anatomy and, to his surprise, a copy of Colin Wilson’s The Occult.

Cleo came back into the room, holding two glasses, ice cubes clinking.

‘You read a lot?’ he asked.

‘Not enough, but I’m a compulsive book buyer. Do you?’

He loved books and bought several every time he went into a bookshop, but he rarely ended up reading them. ‘I wish I had the time; I mostly end up reading reports.’

She handed him a hefty glass tumbler filled with whisky on the rocks, and they sat down together on a sofa, keeping a space between them. She raised her glass, of white wine. ‘Thank you for coming.’

He shrugged, wondering what bombshell she was going to hit him with.

Instead, she said, ‘Cheers, big ears.’

‘Big ears?’

‘Here goes, nose!’

He frowned.

‘You don’t know this?’

‘No.’

‘Cheers, big ears,’ she said. ‘Here goes, nose. Up your bum, chum!’ She raised her glass and took a long swig.

Shaking his head in bewilderment, he took a swig of the whisky; it was dangerously good. ‘What does that mean? “Cheers, big ears”?’

‘Here goes, nose! Up your bum, chum!’

Grace shook his head, not getting it.

‘Just a saying – I’ll have to teach it to you.’

He looked at Cleo, then down at his drink, and sipped some more, changing the subject. ‘So, do you want to tell me about, um – Mr Right? Your fiancé?’

Cleo took another gulp of wine. He watched her, loving the way she drank, no delicate prissy little sip but a proper mouthful. ‘Richard?’

‘Is that his name?’

‘I didn’t tell you his name?’ She sounded astonished.

‘Actually, no. It sort of escaped your mind last night. And on our previous date.’

She peered into her wine glass as if staring at ancient runes. ‘But, everyone – everyone knows about him. I mean – I thought – you must know.’

‘I’m clearly not everyone.’

‘He’s been driving the team at the mortuary nuts for months.’

Grace rattled the ice cubes around in his glass. ‘I’m not sure I’m on your bus.’

‘Number forty-two,’ she said. ‘The meaning of everything? The Hitchhiker’s Guide to the Galaxy?’

‘Right,’ he said, the penny dropping. He wondered for a moment whether Cleo was drunk. But she did not look drunk. Not even tipsy. ‘I’m sorry, I’m lost. You have a fiancé who’s been driving everyone nuts?’

‘I thought you knew,’ she said, looking very meek suddenly. ‘Oh shit, you didn’t, did you?’

‘Nope.’

She drained her glass. ‘Oh God!’ Then she tilted the glass as if searching for a few more drops of precious alcohol. ‘Actually, that’s totally the wrong word to use, the God word.’ She shrugged again.

‘You want to fill me in?’

‘You want the full Richard download?’

‘Might be a good starting point.’

‘Richard and I met about three years ago – he’s a barrister. He came to the mortuary because he wanted to view a body in a murder case he was defending.’ She raised her glass expectantly, then looked disappointed when she saw it was empty. ‘I liked him; we started going out; my parents liked him; my brother and sister both thought he was lovely – and about a year and a half ago we got engaged. But about the same time I discovered I had a big rival. God.’

‘God?’

She nodded. ‘He found God. Or God found him. Whatever.’

‘Lucky Richard,’ Grace said.

‘Very lucky,’ she said with a trace of sarcasm. ‘I envy anyone who finds God; how nice to be able to abdicate all your responsibilities to God.’ Suddenly she stood up. ‘You need any more whisky?’
