The Venice conspiracy

Baldoni turns the page on his flipchart. 'So to recap, we are now looking at three bodies. The oldest victim, a male in his sixties, was dropped about a year and a half ago. The middle victim, a male in his twenties, was dropped about a year ago. And the third victim, a fifteen-year-old female, was discovered this month.' He turns to the expert from RaCIS: 'Isabella, can you help us cement this pattern?'

Lombardelli is casually dressed in a blue roll-neck sweater and jeans, and has the attention of every man in the room even before she speaks. 'Professore Montesano and his team isolated bone sections on both bodies recovered from the lagoon.' She opens a folder and produces a series of slide printouts and overlays. 'We used environmental scanning electron microscopy, ESEM, on the bones. This allowed us to look closely at any false starts, kerf walls and floors caused in the bone, along with draw and pull marks left by the saw. The high magnifications of the ESEM made it possible for us to determine conclusively that a chainsaw had been used for dismemberment of both male bodies.'

One of the team leaders, a man in his late thirties with a dark beard shadow, raises his hand.

Isabella smiles graciously at the interruption. 'Si?'

'Chainsaws are difficult to carry around. Near impossible to conceal and very loud to use. Couldn't it have been a bow saw? I've got a heavy-duty one that I use on timber.'

The scientist's smile widens. 'Then keep it for timber, because it will be little use if you ever need to cut up a corpse. Bow saws, heavy-duty or not, won't cut through thick human bones – it's all to do with the way their teeth are set.'

'Grazie,' says the team leader, with a certain irony.

Isabella picks up where she left off: 'Both male bodies had been dismembered using the same saw, most likely a high-powered petrol model with a chain of fifty centimetres.' She looks towards the man who'd asked the question. 'Such a tool would probably have an engine of about 50 cc – the size of a small moped – so the user clearly wasn't concerned about concealing what he was doing.'

Vito can't help but interrupt. 'To be clear, are you saying that the two male victims are both linked to the same saw?'

Isabella hesitates. 'Correct.'

Montesano interjects, addressing the whole squad: 'Please be careful. The key word here is "linked". The chainsaw was used for dismemberment, not for murder.'

'The professore is quite right,' adds the scientist. 'I'm not telling you only one person was involved. Nor am I telling you that several were involved. That's for you to discover. I'm merely describing for you the single instrument used in the dismemberment.'

The statement is about as definitive as Isabella can make, given the circumstances. She thanks everyone and steps aside for Rocco Baldoni. He flips another page on the chart. 'Some other factors to remember. All three bodies were found within ten kilometres of each other. The ones in the lagoon were considerably decomposed, so we cannot be a hundred per cent certain that the livers were deliberately removed, but we can say the organs were not found with the bodies. Because Monica was not dimembered and therefore there were no saw marks, this organ removal is what primarily links all three cases. Professore Montesano tells us the elderly male victim had extensive injuries to the back of the skull, indicative of a ferocious attack from behind with a blunt object such as a rock or hammer. Despite the advanced state of decomposition of the younger male, there are indications that he suffered stab wounds to the side of his neck. Remember, we already know that Monica Vidic was abducted and restrained by a very controlled and calm killer. He cut her throat while facing her; meaning he was neither squeamish nor inexperienced and actually wanted that eye contact with his victim. I've been talking to our Crime Pattern Analyst and he thinks we're looking at a single, gradually evolving offender. Attack One from behind is cowardly and rushed – a sign the offender was unsure of himself. Attack Two may have been from the side with a knife – indicative of the offender getting closer and bolder in his MO. And the final assault was a full-blown abduction and then a very controlled execution, a sign that the killer was perfecting his technique.'

Valentina raises her hand. 'Monica was stabbed more than six hundred times and her body not dismembered at all. That seems completely at odds with the two earlier corpses.'

'You're right, it does,' says Vito. 'But the stab marks on the male bones and the removal of the liver are key linking factors.'

Valentina presses her point: 'But how do you explain the differences?'

Vito understands her desire to know more about the psychology of the man they're hunting. 'I think our UNSUB was rehearsing on the earlier victims. He was trying to develop a ritualistic way of killing people. He made a real mess of it with the older male victim, tried to be more precise with the second one and finally got it right with Monica.'

Tom catches his eye. 'And now that he's got it right, what next?'

Vito, Valentina and Montesano all answer at the same time: 'He's going to kill again.'

CAPITOLO XXVIII 666 BC

Atmanta Arnza and Masu are only too delighted to have been chosen to carry out Larth's instructions. They've not been long in his employ and he has rarely noticed them, let alone favoured them with tasks of any importance. Even more pleasingly, they have a personal grudge against the netsvis.

They wait until the seer's powerfully built father wanders away and joins a group of other men leaving the temple. Then they move swiftly.

Arnza, the smaller of the two, does the talking. 'Netsvis, on the orders of Magistrate Pesna you are commanded to come with us.'

Before the seer can object, they each have hold of an elbow and he finds himself being marched down the eastern side of the temple.

'What is the purpose of this?' protests Teucer. 'Why such haste that I cannot take my proper leave of the people?'

The guards smirk at each other. 'We are instructed to search you, using whatever force we see fit.'

'Why so? Why do you have to search me?'

Masu waits until they have manhandled him away from the temple and into the thicket behind it. His breath reeks of day-old meat as he pushes his face into Teucer's and sneers, 'You have no idea who we are, do you, Netsvis?'

Teucer half stumbles as they let go of him. Finally his memory stirs. He now recognises their voices, even their smells.

Rapists. The men who held and raped his wife!

'Disrobe, priest!' Arnza draws his sword. 'Take off those garments while we remind you of the cut you gave me and how you killed our friend.'

'I know not of what you speak. I am but a blinded man. A man of the gods.'

'We know who and what you are,' says Arnza, using the point of his sword to prompt Teucer to lift his mantle over his shoulders. 'Get on with it!'

There is a noise in the thicket.

The guard puts his sword to the priest's throat and whispers. 'Speak one word and I will spill your blood.' He nods to Masu to check out the undergrowth.

The big man draws his blade, careful not to make a sound as it slithers free of its sheath. He eases his way through the tangle of twisting, hanging gorse. Twigs crack underfoot.

Teucer speaks in an un-hushed voice: 'Your friend moves with the quietness of an elephant.'

Arnza presses the sword to his windpipe. 'Be quiet.'

'But the gods do not command me to be quiet. They command me to speak.'

The guard leans on his blade again. It nicks Teucer's neck. A thin river of blood springs to the skin. 'You're not as brave now as when you killed Rasce and cut my face, are you?'

Another noise in the bushes.

Arnza spins round.

It is the split second Tetia needs.

She steps behind him and plunges one of Teucer's ceremonial knives into the side of his neck.
