have any relevant information. Now, go away.’

      Argyll was displeased. He liked constructing theories, and generally found the Roman police receptive to them. Well, Flavia sometimes was. Evidently the Los Angeles police were less sophisticated in their approach. He glanced at Morelli, saw that he meant it, and reluctantly left.

      Morelli breathed a deep sigh of relief, and scowled at the quiet snicker from a colleague who’d been listening to his attempts to restore control.

      ‘Right,’ he said. ‘Let’s start again. From the beginning. Can you identify this man?’ he asked formally.

      Thanet swayed once more, but managed to stay perpendicular. This, he said, was Arthur M. Moresby II.

      ‘No doubts?’

      None whatsoever.

      Morelli was deeply impressed. Northern Los Angeles, while not the battle zone of other parts of the city, undoubtedly had more than its fair share of mayhem. Generally speaking, however, the victims were not enormously illustrious. Only rarely did a member of the social register get himself disembowelled. Hollywood directors, television magnates, noted authors, fashion models and all the other exemplars of local industry were usually remarkably adept at keeping themselves alive.

      It also made him rather nervous. He could not remember the figures, but he was willing to bet that the percentage of homicides where he successfully fixed the handcuffs on the guilty party was pretty small. Ordinarily, this was distressing but had few other consequences. People – and that meant his superiors – understood that a conviction was unlikely and didn’t for a moment attach any blame to him. He arrested people often enough to have earned himself a respectable reputation for general professionalism. He did his best and that was that. Better luck next time.

      But he already had a strong feeling that a very large number of people were going to be keeping their eyes on him over this one. This time, doing his best was not going to be good enough.

      ‘I was wondering,’ he went on, ‘about the alarm system. You do have alarms, don’t you?’

      Thanet snorted. ‘Oh yes. This place is wired like Fort Knox.’

      ‘So can we check if any doors except the main entrance were used?’

      ‘Sure. In theory the murderer should have been caught on film in the corridor. Although personally, I’m dubious.’

      Thanet explained that their enormously complicated alarm system included concealed cameras in every room of the museum. Although the administrative block was less well endowed, it was still a bit like a maximum security prison. So they trooped off to the central security office, a room on the third floor crammed with enough electronic equipment to equip a small film studio. While they were eyeing it up and wondering where to start, a tall, balding man in his late thirties came in, radiating nervous excitement.

      ‘Who are you?’ said Morelli.

      The man introduced himself as Robert Streeter, chief security executive, and his curiosity turned to alarm when he was brusquely told that his much vaunted system, responsible both for museum security and his salary, had not so far impressed the police.

      ‘To put it another way,’ the detective informed him, ‘it was a dead loss. If that man Barclay hadn’t discovered the body, no one would have known anything had happened until a hell of a lot later. What good is that?’

      Streeter was also concerned, perhaps even more so than was the detective. After all, his job could depend on this. He had been brought in originally as a consultant when the museum was expanding, to give advice about how to protect the collections. However, as he had discovered, consultancy work was merely an elaborate way of being unemployed, and Streeter’s income had been somewhat erratic at the time. So, spotting his opportunity, he went for it. His report was disdainful, if not devastating. The place was, he concluded, about as secure as the average doll’s house. Not only did he set out a bewildering array of electronic necessities, he accompanied the report with elaborately printed flow diagrams of responsibility structures and integrated fast-response networks to demonstrate how, in the event of a break-in, the felony could be interdicted and the threat neutralised.

      It was all Greek to the museum staff, who accordingly concluded that an integrated fast-response network was an absolute must for anyone who wanted to be on the cutting edge of the museum business. Besides, the man was recommended by Moresby. A college friend of his wife’s or something. So they did the only thing possible, that is, set aside a vast budget, created a new security department and gave Streeter the job of presiding over both. Who began by using the entire allotment to hire secretaries, administrative assistants and liaison personnel in order to lobby for more money. He now had a staff of twelve, another six to patrol the museum, enough electronic gadgetry to make the CIA jealous and was beginning to insist on having the final say on where pictures were hung. In the interests of security. He had even restarted his consultancy business on a sounder footing, and travelled the country giving lectures on ‘Museum security in the modern age’ for hefty fees. It also meant he had less time to spend in Los Angeles, so he was currently bidding for a deputy to take care of day-to-day operations.

      Some people didn’t approve of what they considered Streeter’s imperial tendencies, and Thanet, sensing the growth of an alternative source of power to his own, was one of them. There was no need at all, he suggested, for either Streeter or the vast bureaucracy he had conjured into being. Streeter, not surprisingly, had disagreed quite strongly with this view, and the two men had been at loggerheads ever since. Clearly, a showdown was now in the offing. Recent events would either demonstrate the utter uselessness of all the security systems (victory for Thanet), or indicate the need to work even harder to turn the museum into a cross between Stalag Luft VI and an electronics factory (victory for Streeter). Or, of course, the museum could collapse entirely, and both would find themselves on the breadline.

      Going instantly on the offensive, the security man took a perverse pleasure in pointing out that, in fact, he didn’t really have quite the equipment he had wanted.

      ‘I did indicate at the time the dangers of cutting corners on security. For optimum coverage…’

      ‘Please. That’s not what we’re here for,’ Morelli said, rubbing an inflamed gum and too tired to get involved in domestic squabbles. ‘Why don’t you just show us what you’ve got, not what you wanted.’

      Not before the guided tour. As Streeter set it all out, each room in the museum was covered by a camera system whose lenses swept across a minimum of eighty-two per cent of the area every minute. Equally, they could be automatically directed to particular spots when pressure pads were activated or light-beams cut. The entrycard system automatically logged the entry and exit of everybody employed by the museum, correlated their personal codes to the telephone system so the administration knew where and when they were dialling. More sensors picked up the cards as people moved from room to room, permitting a read-out of their movements. Finally, microphones in every gallery could pick up conversations, in case any visitors were planning a break-in. And, naturally, all the rooms were fitted with smoke detectors, metal detectors and explosives sniffers.

      ‘Christ,’ said a surprised Morelli as this explanation finally came to an end. ‘You’re all ready for Doomsday here. You seem more intent on watching the staff than anything else.’

      ‘You may sneer,’ said Streeter, affronted. ‘But because many of my recommendations were ignored, our employer has been murdered. And now my system is going to tell you who did it.’

      Even Thanet thought that Streeter’s voice lacked its normal conviction as he said this, but Morelli paid no attention, being too busy watching the man manipulate an extraordinary system of controls on the central console. ‘Naturally, the administrative block is less comprehensively covered, but we have adequate visual coverage. I’ve directed the image outputting to this VDU unit,’ he said, pointing a finger.

      ‘He means the picture will be on that television screen,’ Thanet explained helpfully. Streeter glared at him, then turned disdainfully to watch the screen. It remained resolutely blank.

      ‘Ah,’
