but as they turn into the morgue the air goes cold and so does their mood.
Vito walks them towards an old man with a bald, white head that’s wise enough to stay out of Venice’s blistering sun. ‘Officers, this is Professore Sylvio Montesano. Professore, these are lieutenants Valentina Morassi and Antonio Pavarotti, this is their first time in the mortuary.’
‘Then I’m honoured, and very pleased to meet you both.’ Montesano bows, wire bifocals sliding to the tip of his nose. ‘Come with me to the Cooler.’
The fifteen-year-old victim is laid out on a steel gurney, her body bleached white by the overhead lighting, her wounds the colour of putrid veal. Antonio is unfazed but Valentina is already holding a perfumed handkerchief to her mouth.
‘The body is actually in remarkably good condition,’ says Montesano. ‘Oddly enough, submersion in water slows decomposition. We got her in here very quickly, so decay isn’t as advanced as it might have been.’
At a nod from Vito, the medical examiner launches into his report, pitching it so the two lieutenants can easily follow.
‘After the corpse was recovered from the scene we had her CT-scanned in the hospital’s radiological-imaging department. We made examinations every 0.5 millimetres, scouting for two- and three-dimensional reconstructions, so we have very precise data on all the wounds.’ Montesano moves closer to the body. ‘There are two startlingly unusual features to this case. The first is the fatal wound across the throat. Deep into the brachiocephalic artery - that’s our largest artery.’ He points to a spot on the right side of Monica’s neck. ‘It branches off into the carotid and subclavian arteries, pumping blood into this side of the upper chest, arm, neck and head.’
Antonio waves a hand over the mass of other wounds. ‘So, all those other stabbings and injuries - there was no need for them?’
‘In the sense of taking the girl’s life? No need at all. The neck wound was sufficient to have killed her.’ The ME is about to move on, but can’t resist sharing some of his medical knowledge: ‘This is a highly unusual injury. The brachiocephalic artery is a very difficult one to strike. Usually it’s protected by the sternal bone and the clavicles. Generally, when someone’s attacked with a knife to the throat, you expect to see a cut to the left or right common carotid artery.’
Vito is intrigued. ‘But the result is still the same? The victim just bleeds to death?’
‘No, probably not.’ Montesano pushes his glasses back up his nose. ‘Victims of such wounds generally die from air embolus.’ He checks Valentina, anxious to educate rather than traumatise. ‘If the victim’s head and neck are above the level of the heart, then air is drawn into the body - into the veins, mind you, not the arteries. It goes into the right chambers of the heart and forms a frothy mass, stopping the heart from functioning.’
‘But it’s quick and merciful?’ adds Vito, trying to mitigate the effects of this graphic detail on his young female lieutenant.
‘Afraid not,’ says Montesano flatly. ‘It’s far from instantaneous. It can take several minutes.’
Valentina is now sheet-white, but still she manages a question of her own. ‘Did the killer do this with a normal knife?’
Montesano returns his fingers to the girl’s throat. ‘Depends what you mean by normal. The murder weapon had a strong, short blade like a carpet fitter’s tool or artist’s knife. The skin shows that the fatal incision ran from right to left in such a way that the attacker was stood in front and above the victim.’
Vito mimes the knife action above Monica’s head. ‘So, he probably had her restrained on the ground below him, and if the cut ran from the right side of her, we can safely presume the offender is left-handed?’
Montesano looks amused. ‘Major, you are old enough to know that you shouldn’t presume anything.’
‘Okay, I stand
