'All right.' Pio took a folded sheet of paper from his jacket and handed it to Harry. 'The Madrid police found it when they went through Valera 's apartment. Look at it carefully.'

Harry opened the paper. It was an enlarged photocopy of what looked like a page taken from a personal phone book. The names and addresses were handwritten and in Spanish, the corresponding telephone numbers to the right. Most, from the heading, seemed to be from Madrid. At the bottom of the page was a single phone number, to its left was the letter R.

It didn't make sense. Spanish names, Madrid phone numbers. What did it have to do with anything? Except that maybe the R at the bottom of the page referred to Rome, but the number beside it had no name at all. Then it came to him.

'Christ,' he said under his breath and looked at it again. The telephone number beside the R was the one Danny had left on his answering machine. Abruptly he looked up. Pio was staring at him.

'Not just his phone number, Mr Addison. Calls,' Pio said. 'In the three weeks leading up to the killing, Valera placed a dozen calls to your brother's apartment from his cellular phone. They became more frequent toward the end, and of shorter duration, as if he were confirming instructions. As far as we've been able to tell, they were the only calls he made while he was here.'

'Telephone calls do not make killers!' Harry was incredulous. Was this it? All they had?

A newly seated couple looked in their direction. Pio waited for them to turn back, then lowered his voice.

'You were told there is evidence of a second person in the room. And that we believe it was that second person and not Valera who killed Cardinal Parma. Valera was a Communist agitator, but there is no evidence he ever fired a gun. I remind you your brother was a decorated marksman trained by the military.'

'That's a fact, not a connection.'
