Having reached the age at which women begin to employ clothing for purposes of concealment rather than display, Signora Burolo discreetly retained a flowing wrap of some material that was a good deal less transparent than it first appeared.

A sense of revulsion suddenly overcame Zen at the thought of what was shortly to happen to that pampered, veiled flesh. Vanity, lust, jealousy, boredom, bitchiness, beauty, wit – what did any of it matter? As the doomed faces glanced flirtatiously at the camera, wondering how they were coming across, Zen felt like screaming at them, 'Go away! Get out of that house now!'

The Favellonis had done precisely that, of course, which was one reason why everyone in Italy from the magistrate investigating the case to the know-all in your local bar agreed with Zen's mother that Renato Favelloni was 'the one who did it'. With the seedy fixer and his disturbingly bare-breasted wife out of the way, the two maturer couples had settled down to a quiet dinner in the villa's dining room, with its rough tiled floor and huge trestle table which had originally graced the refectory of a Franciscan monastery. The meal had been eaten and coffee and liqueurs served when Oscar once again switched on the camera to record the after-dinner talk, dominated as always by his booming, emphatic voice, punctuated by blows of his hairy fist on the table-top.

Apart from a distant metallic crash whose source and relevance were in dispute, the first sign of what was about to happen appeared in Signora Vianello's nervous eyes.

The architect's wife was sitting next to their host, who was in the middle of a bawdy tale concerning a well-known TV presenter and a stripper turned member of parliament who had appeared on his talk show, and what they had reputedly got up to during the commercial break. Maria Pia Vianello had been listening with a vague, blurry smile, as though she wasn't quite sure whether it was proper for her to appear to understand. Then her eyes were attracted by something on the other side of the room, something which made such considerations irrelevant. The vague smile abruptly vanished, leaving her features completely blank.
