Present Day Carabinieri HQ, Venice For Vito, Valentina and the rest of the murder squad there is no longer day and night.
There is only work. Their lives have been reduced to an endless round of briefings, meetings and fresh crime scenes.
A briefing has been scheduled in a room leading off the one that has recently become home from home for Carvalho's team. The centre of a long table is filled with steel pots of fresh coffee, old white cups and saucers, dull glass tumblers and clusters of bottled water that look like sky-scraper cities built by a kids' art class.
Major Vito Carvalho checks that everyone he needs is present. Sylvio Montesano and two of his assistants occupy the far end of the table. To their left are Rocco Baldoni and Valentina Morassi. Vito wishes she wasn't here. He's urged her to take time off, give herself space to grieve, but she's convinced the best therapy is to throw herself into her work. If he had time to take her to one side, he'd explain just how disastrous that philosophy can be.
The forensics specialists from RaCIS, Isabella Lombardelli and her assistant Gavino Greco, sit to the right of the Medical Examiner and are currently in deep conversation with him about something in a file spread out between them.
Other places are taken by team leaders, officers who head up the various shifts, and those who will oversee house-to-house enquiries or liaise with state prosecutors.
Finally, there is Tom Shaman. Vito had thought long and hard about how much to involve the American. Having him on board as an expert adviser was one thing; letting him into operational briefings was another. In the end he went with his instincts and the fact that in a murder enquiry, especially one involving a possible serial killer, you need every pair of hands and useful brain that you can get.
'Thank you all for coming. Let's get things under way.' He pauses to let the cross-table chatter die down. 'Lieutenant Baldoni will give us an updated overview. Rocco-'
The diminutive detective pushes back his chair and walks to a large white flipchart labelled VICTIMS. 'We now have three bodies.' He needs to stretch to turn the first page. 'Victim One – teenager Monica Vidic. Victim Two – a dismembered male believed to be in his sixties, still unidentified. Victim Three – a dismembered male, still unidentified, estimated to be in his twenties. The two unknowns were found in sacks in the laguna' – he avoids Valentina's eyes – 'close to where the body of our former colleague Antonio Pavarotti was found.' He gestures towards the ME. 'Professore Montesano will circulate a new report at the end of this meeting. For now, Professore, have you any comment on times of death?'
Sylvio Montesano clears his throat. 'Using strontium, iron and polonium, we ran a series of tests to determine the constituents of short, half-light radioisotopes found within the human bones. In this manner we were able to ascertain that the older male had been in the water for approximately eighteen months, while the younger male was dropped in the lagoon about a year ago. That means the gap between the two bodies is approximately six months.'
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.'
