Several decades in the Curia had erased almost all traces of Sanchez-Valdes’s Latin-American Spanish. He fixed Zen with his glaucous, hypnotic gaze.

‘As you may have gathered, there was a suicide in St Peter’s this afternoon. Someone threw himself off the gallery inside the dome. Such incidents are quite common, and do not normally require the attention of this department. In the present instance, however, the victim was not some jilted maidservant or ruined shopkeeper, but Prince Ludovico Ruspanti.’

The archbishop looked significantly at Zen, who raised one eyebrow.

‘Of course, the Ruspantis are no longer the power they were a few hundred years ago,’ Sanchez-Valdes continued, ‘or for that matter when the old Prince, Filippo, was alive. Nevertheless, the name still counts for something, and no family, much less an eminent one, likes having a felo de se among its number. The remaining members of the clan can therefore be expected to throw their not-inconsiderable weight into a concerted effort to discredit the suicide verdict. They have already issued a statement claiming that Ruspanti suffered from vertigo, and that even if he had decided to end his life, it is therefore inconceivable that he should have chosen to do so in such a way.’

The middle finger of Sanchez-Valdes’s right hand, adorned by a heavy silver ring, tapped the tabletop emphatically.

‘To make matters worse, Ruspanti’s name has of course been in the news recently as a result of these allegations of currency fraud. To be perfectly honest, I never really managed to master the ins and outs of the affair, but I know enough about the way the press operates to anticipate the kind of malicious allegations which this is certain to give rise to. We may confidently expect suggestions, more or less explicit, to the effect that from the point of view of certain people, who must of course remain nameless, Ruspanti’s death could hardly have been more convenient or better-timed, etcetera, etcetera. Do you see?’
