With the bomb factory now history, he felt some comfort that his efforts with Invicta had been worth the grief, but ringing in his ears was Rolt’s talk of further ‘gestures’, to stoke the fires of public anxiety. All through his last meeting he had been conscious of Stutz’s shadow looming over Rolt, with his global connections, his people positioned in all the corridors of power. It gave credence to Woolf’s fear of more and bigger things to come. Mandler needed to understand that the bomb-factory discovery wasn’t the end of something but an opening chapter, if Rolt was to be believed. It was Woolf’s suspicions about Rolt that had kicked all this off. Tom had moved from irritation to respect for Woolf and his cussed determination to follow his instincts.

So much was unresolved. Rolt had admitted his collusion in the hostel bombing but no more than that. Stutz’s connection to Zuabi, and indeed Zuabi’s significance, was also still a mystery. Mandler had even cast doubt on his existence. And what was Clements’s connection with Stutz all about? Or was there nothing more to it than the photograph and the Cabinet Office compliments slip?

Tom imagined Clements presiding over all of it, a visit with Stutz here, a dinner with Rolt there, but keeping a safe distance when anything unseemly occurred, then slipping back into his lair in Whitehall, uncontaminated by whatever fallout followed. Perhaps that was where the real power lay, with people like Clements, who controlled much of the fate of the country: unelected, unaccountable and ultimately unassailable.

The sight of an Oryxis logo on the security staff’s epaulettes confirmed his sense of how far Stutz’s tentacles reached: a measure of his influence that was plain for all to see. No better place to hide than in plain view. What bugged Tom most was knowing that the dots they had joined up fell short of Stutz himself. And echoing in his head were Stutz’s words about change coming, Rolt’s coy hints about what lay ahead, and Woolf’s fears about a ‘spectacular’. Whatever Mandler said, all of this led Tom to suspect – to know – that the job was far from done.

Eventually he reached the front of the queue.

As the man patted him down Tom nodded at the epaulettes. ‘This a good gig, with Oryxis?’

He said nothing. Tom noted he also sported an 82nd Airborne tie pin. ‘You still in Fayetteville? When I was there I spent all my money at the Mash House and Hooters.’

The eyes lit up, an instant connection between the two ex-servicemen. Fayetteville was the hometown of Fort Bragg and the 82nd Airborne. Bragg was a city in itself and not only housed the 82nd but also Delta Force. Tom had spent many months with them over the years.

‘Yeah, still there.’

‘I came over and did your jump course. Happy days.’

‘Good as it gets, sure.’
