He reminded Rebus of Gregor Jack. That enthusiasm and energy, that public image. It used to be the sort of stuff Rebus associated with American presidential campaigns; now it was everywhere. Even in the asylums. The lunatics hadn’t taken over; the image-men had.

‘We have just over three hundred patients here,’ Forster was saying, ‘and we like the staff to get to know as many of them as possible. I don’t just mean faces, I mean names. First names at that. This isn’t Bedlam, Inspector Rebus. Those days are long past, thank God.’

‘But you’re a secure unit.’

‘Yes.’

‘You deal with the criminally insane.’

Forster smiled again. ‘You wouldn’t know it to look at most of our patients. Do you know, the majority of them – over sixty per cent, I believe – have above-average IQs? I think some of them are brighter than I am!’ A laugh this time, then the serious face again, the caring face. ‘A lot of our patients are confused, deluded. They’re depressed, or schizophrenic. But they’re not, I assure you, anything like the lunatics you see in the movies. Take Andrew Macmillan, for example.’ The file had been on Forster’s desk all along. He now opened it. ‘He’s been with us since the hospital opened. Before that, he was in much less . . . savoury surroundings. He was making no progress at all before he came here. Now, he’s becoming more talkative, and he seems about ready to participate in some of the available activities. I believe he plays a very good game of chess.’

‘But is he still dangerous?’

Forster chose not to answer. ‘He suffers occasional panic attacks . . . hyperventilation, but nothing like the frenzies he went into before.’ He closed the file. ‘I would say, Inspector, that Andrew Macmillan is on his way to a complete recovery. Now, why do you want to talk to him?’

So Rebus explained about The Pack, about the friendship between ‘Mack’ Macmillan and Gregor Jack, about Elizabeth Jack’s murder and the fact that she had been staying not forty miles from Duthil.

‘I just wondered if she’d visited.’

‘Well, we can check that for you.’ Forster was flipping through the file again. ‘Interesting, there’s nothing in here about Mr Macmillan knowing Mr Jack, or about his having that nickname. Mack, did you say?’ He reached for a pencil. ‘I’ll just make a note . . .’ He did so, then flicked through the file again. ‘Apparently, Mr Macmillan has written to several MPs in the past . . . and to other public figures. Mr Jack is mentioned . . .’ He read a little more in silence, then closed the file and picked up the telephone. ‘Audrey, can you bring me the records of recent visitors . . . say in the last month? Thanks.’

Duthil wasn’t exactly a tourist attraction, and, out of sight being out of mind, there were few enough entries in the book. So it was the work of minutes to find what Rebus was looking for. The visit took place on Saturday, the day after Operation Creeper, but before the story became public knowledge.
