'When will all this be made public?'

'Probably not while the investigation continues. After that we will, in all likelihood, defer to the Vatican.'

Harry folded his hands in front of him and stared at the table. Emotions flooded. It was like being told you had an incurable disease. Disbelief and denial made no difference, the X rays, MRIs, and CT scans stared back from the wall just the same.

Yet, for all of that – for all the evidence the police had presented, one solid piece stacked upon another, they still had no absolute proof, as Pio had admitted. Moreover, no matter what he had told them about the substance of Danny's phone message, only he had heard Danny's voice. The fear and the anguish and the desperation. It was not the voice of a murderer crying out for mercy to the last bastion he knew, but of someone trapped in a terrible circumstance he could not escape.

For some reason, and he didn't know why, Harry felt closer to Danny now than he had since they were boys. Maybe it was because his brother had finally reached out to him. And maybe that was more important to Harry than he knew, because the realization of it had come not as a thought but as a rush of deep emotion, moving him to the point where he thought he might have to get up and leave the table. But he hadn't, because in the next moment another realization had come: he wasn't about to have Danny condemned to history as the man who had killed the cardinal vicar of Rome until the last stone had been turned and the proof was absolute and beyond any doubt whatsoever.

'Mr Addison, it will be another day at least, perhaps more, before the identification procedures are complete and your brother's body can be released to you… Will you be staying at the Hassler the entire time you are in Rome?'

'Yes…'

Pio took a card from his wallet and handed it to him. 'I would appreciate it if you kept me informed of your movements. If you leave the city. If you go anywhere where it would be difficult for us to reach you.'

Harry took the card and slipped it into his jacket pocket, then his eyes came back to Pio.

'You won't have any trouble finding me.'

Euro Night Train, Geneva to Rome.

Tuesday, July 7, 1:20 a.m.

Cardinal Nicola Marsciano sat in the dark, listening to the methodic click of the wheels as the train picked up speed, pushing southeast out of Milan toward Florence and then Rome. Outside, a faint moon touched the Italian countryside, bathing it in just enough light for him to know it was there. For a moment he thought of the Roman legions that had passed under the same moon centuries before. They were ghosts now, as one day he would be, his life, like theirs, scarcely a blip on the graph of time.

Train 311 had left Geneva at eight-twenty-five the night before, had crossed the Swiss-Italian border just after midnight, and would not arrive in Rome until eight the next morning. A long way around, considering it was only a two-hour flight between the same cities, but Marsciano had wanted time to think and to be alone without intrusion.

As a servant of God he normally wore the vestments of his office, but today he traveled in a business suit to avoid attracting attention. To that same end his private compartment in the first-class sleeping car had been reserved under the name N. Marsciano. Honest, yet simple anonymity. The compartment itself was small, but it provided what he needed: a place to sleep, if he ever could; and, more important, a moving station to receive a call on his cellular phone without fear it would somehow be intercepted.

Alone in the darkness, he tried not to think of Father Daniel – the accusations of the police, the evidence they had discovered, the bombed bus. Those things were past, and he dared not dwell on them, even though he knew at some point he would have to confront them again personally. They would have everything to do with his future, the future of the Church, and whether either could survive.

He glanced at his watch, its digital numbers a transparent green in the dark.

1:27

The Motorola cell phone on the small table beside him remained silent. Marsciano's fingers drummed on the narrow arm of his chair, then pushed through his gray-white hair. Finally he leaned forward and poured what was left of the bottle of Sassicaia into his glass. Very dry, very full-bodied, the stately red wine was expensive and little known outside Italy. Little known because the Italians themselves kept it a secret. Italy was filled with secrets. And the older one got, the more there seemed to be and the more dangerous they became. Especially if one were in a position of power and influence, as he was at age sixty.

1:33

Still the phone remained silent. And now he began to worry that something had gone wrong. But he couldn't let himself think that way until he knew for sure.

As he took a sip of the wine, Marsciano's gaze shifted from the phone to the briefcase lying flat on the bed beside it. Inside, tucked away in an envelope beneath his papers and personal belongings, was a nightmare. An audiocassette that had been delivered to him in Geneva Sunday afternoon during lunch. It had come in a package marked URGENTE and had been delivered by messenger with no return address or indication of who had sent it. Once he had listened to it, however, he knew instantly where it had come from and why.

As president of the Administration of the Patrimony of the Apostolic See, Cardinal Marsciano was a man in whose hands rested the ultimate financial decisions for the investment of the Vatican 's hundreds of millions of dollars in assets. And as such, he was one of the very few who knew exactly how much those assets were worth and where they were invested. It was a position of solemn responsibility and by its very nature open to those things men in high station are always heir to – the corruption of mind and spirit. Men who fell to such temptations usually suffered from greed or arrogance or both. Marsciano was afflicted by neither. His suffering came from a cruel intermingling of profound loyalty to the Church, grievously misplaced trust, and human love; made worse, if that were possible, by his own high position within the Vatican.

The tape recording – in light of the murder of Cardinal Parma and the timing of its delivery – only pushed him farther into darkness. More than simply threaten his own personal safety, by its very existence it raised other, more far-reaching questions: What else was known? Whom could he trust?

The only sound was that of the wheels passing over the rails as the train drew ever closer to Rome. Where was the call? What had happened? Something had to have gone wrong. He was certain now.

Abruptly the phone rang.

Marsciano was startled and for a moment did nothing. It rang again. Recovering, he picked up.

'Si.' His voice was hushed, apprehensive. Nodding almost imperceptibly, he listened. 'Grazie,' he whispered finally and hung up.
