He waited until he was waved to a chair, then sat and handed the maresciallo the plastic folder he had prepared. A waiter approached. He ordered Coca-Cola. The folder, with the name on it of Marianna Rossetti and that day’s date, was opened. His report covered five closely typed pages. He knew that, two days before, the maresciallo had met with the girl’s father and was aware of the circumstances and cause of the girl’s death. He himself had been ordered to the basilica and the cemetery to watch, listen – it had been explained to him that the family’s emotions ran high. Also, he knew that a researcher at the hospital had published material in the foreign-language edition of the Lancet Oncology under a title that referred to il triangolo della morte, and that in the secure archive section of the barracks there was a small mountain of files dealing with the area’s contamination. The maresciallo had read the first two pages, and he sat in silence. The waiter brought his Coca-Cola, with an espresso and a large measure of Stock brandy. He had known the maresciallo always spent time here in the evening and that he could be certain of finding him. He tried to read the other man’s face, but saw nothing. He had hoped for praise.

The question was as blunt as it was unexpected: ‘Have you drunk alcohol tonight?’

And he had believed that praise was due. The father and mother of the deceased had made no attempt to lower their voices so he had heard them crystal clear. Within minutes what they had said was written in his notebook as virtual verbatim. He had the accusation, the condemnation and the name. An older man, jaundiced and cynical, from long service with the Arma – what the carabinieri called themselves – might have hung back, lounged against a distant headstone, smoked a quiet cheroot and reflected on what a shit place Nola was. The young man had made certain he was close enough to hear every word and to see the violence shown towards the woman. He accepted that he would not be praised.
