The official paused, awaiting Zen’s response. At length, realizing that it would not be forthcoming, he continued.

‘With the aforesaid factors in mind, a decision has been made at ministerial level to deploy a pool of mature and experienced officials such as yourself to liaise directly with members of the Polizia Statale seconded to the DIA. Your role will be firstly to report to us here at the Viminale on the nature and scope of DIA initiatives, both current and planned, secondly to monitor the response of all local personnel to ensuing governmental directives, and thirdly to communicate these in turn to Rome, all with a view to expediting an efficient and unproblematic implementation of official policy Do you understand?’

Zen understood only too well: he was being asked to act as a spy. The position of Head of Post in each DIA office was allocated in turn to a representative of one of the police forces involved, each responsible to a different ministry in Rome: Defence, Finance, or Interior. The novelty of the DIA was that it had been set up from the first as a cooperative venture involving all three forces, and had been specifically designed to function independently of any ministerial interference.

At the time, in the wake of the bloodbath initiated by the Corleone clan, and the killings of General Dalla Chiesa and the judges Falcone and Borsellino, it would have been politically unthinkable for any interested party to try to limit or control that independence. But times had changed. The Mafia had apparently been broken, with all but a few of its top capi jailed or in hiding, and there had been no large-scale outbreaks of violence for several years. Clearly someone in Rome, possibly several people, felt that the moment was now propitious to rein in this too-efficient and semi-autonomous organization. Even the public seemed to be starting to feel that enough was enough. Where would it all end? Were we to bring back the Inquisition?
