'Do you think it's police business, sir?'

Jack looked up with glinting eyes. 'That's the crux, isn't it? If I report her missing… I mean report her officially… and she's found, and it turns out she was simply keeping out of things…?

'Does she seem the type who would stay out of things, sir?' Rebus's thoughts were spinning now. Someone had set Jack up… but not his wife, surely? Sunday newspaper thoughts, but still they worried him.

Jack shrugged. 'Not really. It's hard to tell with Liz. She's changeable.'

'Well, sir, we could make a few discreet inquiries up north. Check hotels, guest houses -'

'It would have to be hotels, Inspector, where Liz is concerned. Expensive hotels.'

'Okay then, we check hotels, ask around. Any friends she might visit?'

'Not many.'

Rebus waited, wondering if Jack would change his mind. After all, there was always Andrew Macmillan, the murderer. Someone she probably knew, someone nearby. But Jack merely shrugged and repeated, 'Not many.'

'Well, a list would help, sir. You might even contact them yourself. You know, just phoning for a chat. If Mrs Jack was there, they'd be bound to tell you.'

'Unless she'd told them not to.'

Well, that was true.

'But then,' Jack was saying, 'if it turned out she'd been off to one of the islands and hadn't heard a thing…'

Politics, it was all about politics in the end. Rebus was coming to respect Gregor Jack less, but, in a strange way, like him more. He rose and walked over towards the shelf unit, ostensibly to put his glass there. At the mantelpiece, he stopped by the card and picked it up. The front was a cartoon showing a young man in an open-topped sports car, champagne in an ice bucket on the passenger seat. The message above read GOOD LUCK! Inside was another message, written in felt pen: 'Never fear, The Pack is with you'. There were six signatures.

'Schoolfriends,' Jack was saying. He came over to stand beside Rebus. 'And a couple from university days. We've stuck pretty close over the years.'

A few of the names Rebus recognized, but he was happy to look puzzled and let Jack provide the information.

'Gowk, that's Cathy Gow. She's Cath Kinnoul now, Kinnoul as in Rab, the actor.' His finger drifted to the next signature. 'Tampon is Tom Pond. He's an architect in Edinburgh. Bilbo, that's Bill Fisher, works in London for some magazine. He was always daft on Tolkien.' Jack's voice had become soft with sentiment. Rebus was thinking of the schoolfriends he'd kept up with – a grand total of none. 'Suey is Ronnie Steele…'

'Why Suey?';

Jack smiled. 'I'm not sure I should tell you. Ronnie would kill me.' He considered for a moment, gave a mellow shrug. 'Well, we were on a school trip to Switzerland, and a girl went into Ronnie's room and found him… doing something. She went and told everyone about it, and Ronnie was so embarrassed that he ran outside and lay down in the road. He said he was going to kill himself, only no cars came past, so eventually he got up.'

'And suicide abbreviates to Suey?'

'That's right.' Jack studied the card again. 'Sexton, that's Alice Blake. Sexton Blake, you see. A detective like yourself.' Jack smiled. 'Alice works in London, too. Something to do with PR.'

'And what about…?' Rebus was pointing to the last secret name, Mack. Jack's face changed.

'Oh, that's… Andy Macmillan.'

'And what does Mr Macmillan do these days?' Mack, Rebus was thinking. As in Mack the Knife, grimly apt…

Jack was aloof. 'He's in prison, I believe. Tragic story, tragic.'

'In prison?' Rebus was keen to pursue the subject, but Jack had other ideas. He pointed to the names on the card.

'Notice anything, Inspector?'

Yes, Rebus had, though he hadn't been going to mention it. Now he did. 'The names are all written 'by the same person.'

Jack gave a quick smile. 'Bravo.'

'Well, Mr Macmillan's in prison, and Mr Fisher and Miss Blake could hardly have signed, could they, living in London? The story only broke yesterday…"

'Ah yes, good point.'

'So who…?'

'Cathy. She used to be an expert forger, though you might not think it to look at her. She used to have all our signatures off by heart.'

'But Mr Pond lives in Edinburgh… couldn't he have signed his own?'

'I think he's in the States on business.'

'And Mr Steele…?' Rebus tapped the 'Suey' scrawl.

'Well, Suey's a hard man to catch, Inspector.'

'Is that so,' mused Rebus,' is that so.'

There was a knock at the door.

'Come in, Helen.'

Helen Greig put her head round the door. She was dressed in a raincoat, the belt of which she was tying. 'I'm just off, Gregor. Ian not back yet?'

'Not yet. Catching up on his sleep, I expect.'

Rebus was replacing the card on the mantelpiece. He was wondering, too, whether Gregor Jack was surrounded by friends or by something else entirely…

'Oh,' said Helen Greig, 'and there's another policeman here. He was at the back door…"

The door opened to its full extent, and Brian Holmes walked into the room. Awkwardly, it seemed to Rebus. It struck him that Holmes was awkward in the presence of Gregor Jack MP.

Thank you, Helen. See you tomorrow.'

'You're at Westminster tomorrow, Gregor.'

'God, so I am. Right, see you the day after.'

Helen Greig left, and Rebus introduced Jack to Brian Holmes. Holmes still seemed unnaturally awkward. What the hell was the matter? It couldn't just be Jack could it? Then Holmes cleared his throat. He was looking at his superior, avoiding eye contact with the MP altogether.

'Sir, er… there's something maybe you should see. Round the back. In the dustbin. I had some rubbish in my pockets and I thought I'd get rid of it, and I happened to lift the lid off the bin…'

Gregor Jack's face turned stark white.

'Right,' said Rebus briskly, 'lead the way, Brian.' He made a sweeping motion with his arm. 'After you, Mr Jack.'

The back of the house was well lit. Two sturdy black plastic bins sat beside a bushy rhododendron. Each bin had attached inside it a black plastic refuse bag. Holmes lifted the lid off the left-hand bin and held it open so that Rebus could peer inside. He was staring at a flattened cornflake packet and the wrapping from some biscuits.

'Beneath,' Holmes stated simply. Rebus lifted the cornflake packet. It had been concealing a little treasure chest. Two video cassettes, their casings broken, tape spewing from them… a packet of photographs… two small gold-coloured vibrators… two pairs of flimsy-looking handcuffs… and clothing, body-stockings, knickers with zips. Rebus couldn't help wondering what the hacks would have done if they'd found this lot first…

'I can explain,' said Jack brokenly.

'You don't have to, sir. It's none of our business.' Rebus said this in such a way that his meaning was clear: it might not be our business, but you'd better tell us anyway.

'I… I panicked. No, not really a panic. It's just, what with that story about the brothel, and now Liz is off somewhere… and I knew you were on your way… I just wanted rid of the lot of it.' He was perspiring. 'I mean, I know it must look strange, that's precisely, why I wanted rid of it all. Not my stuff, you see, it's Liz's. Her friends… the parties they have… well, I didn't want you to get the wrong impression.'

Or the right impression, thought Rebus. He picked up the packet of photographs, which just happened to burst open. 'Sorry,' he said, making a show of gathering them up. They were Polaroid's, taken at a party it was true. Quite a party, by the look of it. And who was this?

Rebus held the photograph up so that Jack could see it. It showed Gregor Jack having his shirt removed by two women. Everyone's eyes were red.

The first and last party I ever went to,' Jack stated.

'Yes, sir,' said Rebus.
