‘What did you do?’ demanded Porfiry.
‘I simply asked them if they wanted to smell some of the adipocere.’
Porfiry blinked in astonishment. ‘And now we have lost our official witnesses! You are aware that we cannot proceed without them. You may resent the presence of unqualified laymen to supervise you, but the law requires it.’
‘Supervise? I hardly think that is the right word.’ A flash of indignation came into the doctor’s tone. ‘As I understand it, Porfiry Petrovich, the law merely requires that they sign the papers affirming that they have presented themselves here today in the capacity of official witnesses. I took the precaution of having them complete that minor administrative detail before uncovering the body.’
‘And then you promptly scared them off.’
‘Scared them off? Do you really think so?’
‘Don’t play the innocent with me.’
‘I was only trying to demonstrate to them that the adipocere was the source of the rank smell that they had themselves commented on. I told them it was adipocere, but they looked at me blankly. So I had Valentin Bogdanovich scoop some out on a spatula and offer it to them.’
As if to confirm the doctor’s account, the diener thrust out a wooden spatula towards Porfiry. On the end of it was a small mound of something soft and white.
‘Adipocere is the most interesting substance,’ continued Dr Pervoyedov, as Porfiry leant forward gingerly and inhaled. ‘Many writers, the Englishman Taylor for instance, describe its odour as highly offensive. And yet, I wonder, if you did not know that it had been taken from a corpse, would you necessarily be repelled by the smell? It’s an interesting question, is it not, Porfiry Petrovich?’
‘There is no question about it,’ said Porfiry, screwing up his face. ‘It is a disgusting smell. Unequivocally.’
‘Un-equivocally, you say? But what do you make of Casper, a German, and one of the foremost authorities of forensic medicine, who, I believe, rather likes the smell. By no means disagreeable, are his words — if memory serves me right. A little cheesy, but by no means disagreeable, is how he describes it.’
‘I would say that Dr Casper has become too habituated to the smells of the charnel house.’
‘Perhaps! That is certainly possible.’ Dr Pervoyedov chuckled, as if at a private joke. ‘I myself incline to Casper’s view,’ he admitted shyly.
‘Then the same may be said of you,’ commented Porfiry.
‘But is it really soap?’ asked Virginsky abruptly, having also sniffed at the sample on the diener’s spatula.
‘Yes. Soap. Ammoniacal or, sometimes, calcareous soap. In the case of the latter, it is thought that the body first forms ammoniacal soap and that this is subsequently further converted by the presence of lime. But, yes, soap, of one form or another. The process by which the body is converted to adipocere is known as saponification.’
‘Could you wash yourself with it?’ wondered Virginsky. He looked down at the face of the unknown man on the trestle table. Two glistening white patches showed where his cheeks once were. ‘He is turning into a bar of soap.’
‘He was. Since he has been taken out of the water and dried out somewhat, the process has stopped.’ Dr Pervoyedov took a spatula of his own and prodded gently at one of the white cheeks. ‘You will notice too that the adipocere on his face has hardened, due to its exposure to air.’
‘How long does it take for a body to be completely converted to adipocere?’ asked Porfiry.
‘In the case of an adult body totally immersed in water, about a year.’
‘And so, from the degree of saponification, you will be able to calculate how long he has been in the canal — giving us an approximate date of death?’
‘Approximate, very approximate. One may not set one’s watch by adipocere. It is an erratic and inconsistent material. It has no organic structure, you know. How it behaves in one case, on one body, may not necessarily be repeated in another.’
‘And as for cause of death?’ asked Porfiry, a little impatiently. ‘Do you have any opinions pertaining to that?’
‘All in good time, Porfiry Petrovich. We have not even commenced the examination. I have been waiting for you, you know.’
‘You did not wait for me before you started dishing out mortuary wax.’
‘I assure you that there is more than enough to go round.’ It seemed that Dr Pervoyedov had misunderstood Porfiry’s objection. He bowed to his diener, who began cutting away the dead man’s clothes.
‘But you must have already noticed the wound on the side of the head?’ Porfiry’s voice was imploring. ‘That’s all I meant to suggest.’
‘As you know, Porfiry Petrovich, I follow the Virchow method.’ Dr Pervoyedov angled his head almost tenderly as he watched the diener work. ‘In the Virchow method, the organs are removed and examined separately. In due order. However, adipocere has a rather interesting attribute that does somewhat compromise any forensic examination, whether by the Virchow method or any other.’
‘And what is that?’
‘All tissue, including organs, skin, musculature and fat — even blood and blood vessels — all is equally capable of conversion to adipocere. Indeed, in a body that has undergone complete saponification, it is impossible to distinguish the internal organs at all. One is simply confronted by a mass of soapy material. Similarly, it becomes impossible to distinguish flesh that has been subject to trauma from flesh that has not. Damaged tissue simply melts away and becomes one with the undamaged tissue. All is. .’
‘Soap,’ completed Virginsky, wonderingly.
‘Yes. And the more of his body that has turned to adipocere, the harder it will be to make any firm conclusions about the cause of death.’
The body now lay unclothed, the considerable bulk of the belly sprawling out on either side. Further patches of white were visible in certain places, noticeably at the chest, thighs and upper arms. Porfiry noticed that the man was circumcised.
Dr Pervoyedov looked down at the body wistfully. ‘Even so, one must adhere to the method. If we abandoned the method, where would we be? And the first thing that the method calls for is that the physician conduct a thorough visual examination of the exterior of the body.’ Dr Pervoyedov proceeded to put his words into practice, in a series of exaggerated swoops. He was like a hen pecking at grain, ducking his head sharply down towards the body on the table and back up again. All the time, he continued his explanation: ‘Thorough, Porfiry Petrovich. That’s the watchword. I should be a poor pathologist if I confined my observations to the head and offered an opinion based only on what I saw there. What if a further trauma were subsequently revealed, upon removal of the clothing?’
Porfiry waited impatiently for Dr Pervoyedov to cease his examination. ‘Well then, can you see any other wound, liable to have resulted in the victim’s death?’
‘There are a number of abrasions, particularly around the wrists and ankles.’ Dr Pervoyedov pointed out the marks.
‘He was tethered to some stones,’ remarked Porfiry. ‘I take it these abrasions could not in themselves have proved fatal.’
‘They may even have been inflicted post-mortem. However, I have yet to examine the victim’s back.’ The doctor signalled to his diener, who hefted the body over with a savage grunt. Further white patches showed on the back, at the buttocks and kidneys.
‘And yet. .’ There was a note of exasperation in Porfiry’s voice. ‘And yet, we do have evidence of a major trauma to the head, do we not? The only significant wound visible, as far as I can see. To your expert eye, does that wound appear sufficient to have caused this man’s death?’
Dr Pervoyedov broke off from his swooping examination of the body and turned to Porfiry. His look was one of wounded disappointment, like a child who had been deprived of a favourite toy. ‘Well, yes, it is difficult to imagine how anyone could survive such a trauma.’
