the window. He was very pale.
    Professor Wilson drew blood from the femoral veins at the top of the legs, and vitreous fluid from the eyes. Fin always found it hard to watch a needle entering an eyeball. There was something peculiarly vulnerable about the eyes.
    Muttering almost inaudibly into a hand-held recorder, the professor examined first the feet and then the legs, noting reddish-purple bruising on the knees, before coming to the opening in the abdomen. ‘Hmmm. The wound starts higher up on the left side of the abdomen, with the terminus lower on the right, tapering away almost to a skin scratch at the very tip.’
    ‘Is that significant?’ Fin said.
    The professor straightened up. ‘Well, it means that the blade used to inflict the wound was slashed across the abdomen right to left, from the killer’s perspective.’
    Fin suddenly saw his point. ‘It was left to right in Edinburgh. Does that mean one was right-handed, the other left?’
    ‘We can’t tell handedness, Fin. You should bloody well know that by now! You can slash either way with the same hand. All it means is, they were different.’ He ran a latexed finger along the upper edge of the wound, where the skin had darkened as it dried. ‘The wound inflicted on the Edinburgh victim was deeper, too, more violent, severing the mesentery from the retroperitoneum. You’ll remember, there were about three feet of small intestine hanging between the legs in loops that had been partially severed and drained.’ Fin recalled the smell of it at the scene, streaks of pale green and yellow marbling the blood on the pavement. And at the post-mortem the small bowel, emptied of its juices, had been a dull, dark gold in appearance, quite unlike Angel’s. ‘There’s just a wedge of omentum which has pushed out here, and a bulb of the transverse colon.’ The professor worked his way around the wound and its protrusions. He measured it. ‘Twenty-five and a half centimetres. Shorter, I think, than in Edinburgh, but I’ll need to check that. And this man’s much heavier. He would have presented a bigger target area.’
    The external examination moved on to the hands and arms. The professor noted bruising around both elbows. There were old scars on hands ingrained with oil, and he scraped some of the black accumulation of it from beneath bitten fingernails. ‘Interesting. These certainly do not look like the hands of a man who put up a desperate struggle to ward off his attacker. There is no sign of trauma, no skin beneath the fingernails.’
    Careful scrutiny of the chest showed no trauma there either. But there was clear bruising on the neck, the same reddish-purple as the knees and the elbows. A row of four round bruises on the left side of the neck, two of them close to half an inch in diameter, one larger oval on the right side. ‘Consistent with having been caused by fingertips. And you can see the little crescent-shaped abrasions associated with them. Made by the killer’s fingernails. There are tiny flakes of skin heaped up at the concave side.’ The professor glanced up at Fin. ‘It’s interesting, you know, how little pressure it takes to strangle someone. You don’t have to stop them breathing, just prevent the blood draining from the head. The jugular veins that carry blood away from the head only require about four and a half pounds of pressure to cut them off. Whereas the carotid arteries carrying blood to the head require about eleven pounds to put them out of action. You’d have to apply about sixty-six pounds of pressure to cut off the vertebral arteries, and thirty-three pounds to choke off the trachea. In this case you can see the florid petechial haemorrhaging around the face.’ He peeled back the eyelids, beneath a large purple bruise on the right temple. ‘Yes, and also here around the conjunctivae. Which would suggest that death might have been caused by cutting off the venous drainage.’
    He moved back to the neck. ‘Interesting,
