The cafe was starting to fill up now. It was small and rather seedy for this area, and the clientele was very different from that at the previous establishment: tradesmen, street sweepers, delivery drivers, city cops, pensioners, janitors…

It took another moment before the penny dropped, and when it did Gabriele had enough sense not to use his mobile. The cafe‘s pay phone was at the rear of the establishment, in an overflow zone where the tables and chairs began to peter out and be replaced by stacks of mineral water cases, cardboard boxes of crisps, unused advertising materials and a broken ice-cream freezer with its lid up. On the wall nearby hung a framed black-and-white aerial photograph of a small town somewhere in the alluvial flatlands to the south, Crema or Lodi perhaps. It must have been taken shortly after the war, for there was still little extensive development outside the walls, just a few suburban villas and the railway station. After that the vast plains spread away, faintly lined with dirt roads and dotted at intervals with isolated cascine, the rectangular complexes of clustered farm buildings characteristic of the Po valley.

He stood there, phone in hand, staring up at the photograph. Eventually the dialling tone changed to an angry whine. Gabriele hung up, fed in a coin and redialled. He knew what to do now, and it could be done.

‘ Pronto.’

‘Fulvio, it’s Gabriele Passarini.’

‘ Salve, dottore.’

‘Listen, you remember that time, years ago, when I locked myself out of the shop?’
