What he hadn’t anticipated was how she would stir him up on a professional level. The pleasure he’d taken in the preparation they’d done had been the mental equivalent of a cold shower. It had snapped his synapses to attention in a way that no interaction with undergraduates had ever done. It had reminded him that he was operating at about half his capacity here at the university, and while that might have been sensible as a kind of convalescence from the harrowing he’d undergone at the hands of Jacko Vance, it was no way to spend the rest of his life. If he’d needed further reinforcement, it had just fallen into his lap.

He’d always feared this moment. Deep down, he’d known the siren call of what he did best might rise again to waken him from the slumberous existence he’d chosen. And he’d done everything in his power to guard against that moment. But the combination of the news of Jacko Vance’s appeal and the return of Carol Jordan had been too strong for his fortifications.

Things had changed since he’d last been in the front line, he knew that. Quietly, privately, the Home Office had taken a sideways step from using professional psychologists as consultants on complex serial murder investigations. The publicity that had been generated by their earlier policy had given them too many sweaty-palmed moments for them to be willing to continue it indefinitely. Not everyone was as talented as Tony; and few were as close-mouthed. Although there were still a handful of experts who were called in on an ad hoc basis, the police had been busy behind the scenes building their own skills base at the National Crime Faculty at Bramshill. Now there was a new breed of criminal analyst, officers trained in an impressive mixture of psychological skills and computer navigation. Like the FBI and the Canadian RCMP, the Home Office had decided that it was better to rely on police officers trained in specialist areas than to call on the sometimes questionable skills of clinicians and academics who, after all, had no direct experience of what it took to catch a criminal. So, in one sense, there was no longer a place for Tony doing what he believed he had a unique talent for. And after the last debacle there was no way any politician would agree to give him any training or developmental role.

But perhaps there was something else he could offer. Perhaps he could find a niche that would allow him occasionally to flex his analytical muscles in pursuit of the profoundly disturbed minds who committed the most unreadable of crimes.

And perhaps this time, with Carol almost certainly moving to some new role in Europol, he could escape the turmoil that had accompanied his last two excursions into the minds of serial killers. It was certainly worth thinking about.
