      The initial discovery was made by the gardener of the Giardinetti Reali, an old and stooped figure whose labours generally pass unnoticed by the millions of tourists who come to Venice every year, even by those who eat their sandwiches amidst his creation as they get their breath back from overdosing on architectural splendour.

      For all that he was underappreciated, the old man was obsessed with his job. In this he was rare. Venice is not noted for its enthusiasm for nature; indeed, its entire history has been dominated by the need to keep the elements from interfering in its business. A flowerpot hanging out of a window is generally the closest the inhabitants come to the joys of the wild. Most cannot even see an open space without imagining it neatly covered with stone flaggings. If you want to grow things, go to the mainland; real Venetians don’t dig holes.

      So the gardener felt himself to belong to a small and somewhat persecuted minority. A couple of acres of garden wedged between the Piazza San Marco and the Grand Canal. Flowerbeds to dig, grass to cut, trees to prune and tend, sea water to keep at bay. All with little help and less money. But today, Saturday, was a big day. The City had especially asked him to provide flowers for a banquet to be held on the Isola San Giorgio that evening. He would give them his best, three dozen lilies he had been cultivating for months in one of his little greenhouses. They would be admired, and he would be praised. A great day.

      There was a lot to be done. Cut the flowers, trim them, prepare them, wrap each one carefully and individually, then send them off to take their part in the wonderful arrangements which, he was sure, would be the talk of the evening. So he got up early, just after six, downed a coffee and a glass of acqua vita to get the blood going, and set off in the chilly, damp weather of late autumn to start work. Although cold and still not fully awake, he felt a small surge of anticipatory pleasure as he neared the greenhouse, looming up out of the early morning sea mist that invariably hangs over the lagoon at this time of day and at this time of year.

      Until, that is, he opened the door and saw the crushed, mangled and twisted remains of the upright and beautiful flowers that he had so carefully tended. The exquisite creatures he had left the night before were no more. He could not believe his eyes. And then he saw the curled up form of the drunken, late-night reveller in the middle of the flowerbed who was evidently responsible.

      He tried to restrain himself, but could not, and let out his venom by trying to wake up the wretch with a well-aimed kick. A woman. When he was young, women knew how to behave properly, he thought bitterly. Nowadays…

      ‘Damn you, move. Wake up. Look what you’ve done,’ he shouted angrily.

      No reply. He put the toe of his shoe underneath the unconscious figure and turned it over, so he could insult the destructive, malicious creature more effectively.

      ‘Mother of God,’ he said instead. And ran for help.

      ‘Murder,’ said General Taddeo Bottando, with a ghoulish smile on his face as he sat in his sunlit office in central Rome. ‘Murder,’ he repeated, evidently enjoying the word and the reaction that showed up on the face of the assistant sitting opposite him. ‘Bloody and violent,’ he added, folding his arms over his protuberant stomach, just to make sure there was no mistake in the matter.

      It was Sunday, the day after the Venetian gardener had discovered the devastation in his flowerbeds. Since he had run, shocked and alarmed, to find a telephone and call the police, Italian officialdom had been thrown, if not quite into a frenzy of activity, at least into a state of decorous movement. As a result, General Bottando had reluctantly come into his office on his day of rest, and had summoned his assistant from her bed to help.

      It is, after all, very thoughtless of anyone to go and die in a foreign land. Indeed, if travellers realised how much trouble it caused, most would undoubtedly delay their departure from this world until they got back home. Firstly, the local police have to be informed, and doctors, ambulances, pathologists and so on brought in to deal with the corpse. Then a message has to be passed to the consulate, which contacts the embassy, which contacts the authorities back home, who contact the local police, who have to inform next of kin. And that is only the start. When you add on the
