Mad Hatter's Holiday (17 page)

‘I have no recollection,’ said Prothero.

‘I didn’t expect you to have, sir, particularly as there was no sign of the mark fourteen days after, when the boy’s body was examined. These things heal quickly, especially in the young. You don’t mind if I have the last doughnut? It’s more than I could do to leave it.’

‘What was the other thing that emerged from the statements?’

Cribb chewed heartily and used the uneaten portion of the doughnut to emphasise his points. ‘Ah, yes. The length of your holiday. Your wife said you were there for three weeks, but you stayed for four.’

‘There were things to attend to, consequent upon the death of Bridget.’

Cribb smiled. ‘I can well imagine, Doctor. But once the severed hand was discovered in the aquarium, on the Monday, there wasn’t much prospect of disposing of the body, which was already dismembered. Just time, perhaps, to bury the head somewhere else in hope of preventing identification. But by the middle of the week the rest of the parcels were found. If you’d left the town at once, suspicions might have been aroused, I agree, but you could have left quite openly at the end of the week, when your holiday was due to finish. Instead, you
extended
it by a week.’

‘It was only right that I should see things through, as Bridget’s employer.’

Cribb dismissed this with a quick shake of the head. ‘It
was
obvious to anyone that the matter had passed out of your control. Bridget was the subject of a murder inquiry, and an inquest was certain to be arranged. You could have been waiting for months if that was why you were still in Brighton. No, I think your motive was another one. You stayed there because of Guy, not Bridget. You
knew
he was going to die on the second Sunday after the murder. It was quite contrary to your plans that he should die at home in Dorking. There would have been no end of questions and suspicions. Instead, he died on the way home, in a public hotel, as you so rightly said.’

‘I am supposed to have known all this? How do you imagine I possessed such clairvoyance, Sergeant?’

Cribb wiped his fingers with the table-napkin. ‘No clairvoyance to it, sir. Timing, that’s all. Fourteen days from the injection, Sunday to Sunday.’

‘This is too preposterous!’ said Prothero. ‘Am I seriously supposed to have killed my own son with an injection of atropine that took effect two weeks after it was given, caused a violent death with all the symptoms of asthma and left no trace in the body? You had better spend some more time with the medical books, Sergeant. You have a lot to learn.’

‘I appreciate that, Doctor. So when I formed my suspicions, I went back to the library to read all that I could find on the subject of injections—and the deuce of a lot there is. What caught my interest in particular were the inoculation experiments being carried out by Dr. Pasteur and others. In fact, it seems that half the doctors in Europe are busy pumping germs into dogs and guinea-pigs and publishing their results.’

Dr. Prothero sighed in a long-suffering way. ‘Perhaps what you fail to appreciate, Sergeant, is that such experiments are intended to give protection against disease, in the same way as vaccination. Now that the organism responsible for typhoid fever has been discovered in Germany, for example, it is possible that we shall soon be able to inoculate the populace and so limit the spread of the disease. Experiments are already being conducted to that end.’

‘So I read, sir. But it isn’t quite so straightforward, is it? There are problems. While I was reading of these experiments I several times came across something the doctors describe as “acute respiratory shock”, which seemed to have nothing at all to do with the disease under investigation. An animal that had been injected would suddenly appear to suffer extreme difficulty in breathing, followed by convulsions which frequently ended in death. Now this interested me a lot, so I went back to Harley Street to see if someone could explain a little more about it in simple terms comprehensible to a member of the Force, such as myself.’

‘It is a phenomenon well known among doctors,’ said Prothero.

‘So I learned, sir, so I learned. But not so well known to the public. The medical profession is at pains not to reveal too much about it, since it only arises in connection with inoculation experiments. I have it on authority that a number of human patients are reported to have died in that way after experiments in Germany. It’s liable to hold up mass-inoculation by several years until it’s properly understood. But even if the doctors can’t explain
why
it happens, they understand the conditions that are conducive to it.’

‘The vaccines used in the German experiments were prepared with chick embryos, and the patients who died were sensitive to eggs. I don’t know where this is leading us, Sergeant.’

‘Don’t you, sir? Well, as I understand it, the kind of violent reaction the doctors call acute respiratory shock can be induced in the laboratory. It was done as early as 1839 by the famous French physiologist, Francois Magendie, injecting dogs with egg-white. He discovered that two injections of egg-white at an interval of fourteen days produced acute respiratory shock. After the second injection the dogs died within five minutes. Now the curious thing is that egg-white isn’t what you’d call a death-dealing substance. In fact, it’s usually regarded as an antidote. It was obviously something to do with the period between the injections, because dogs injected after one week suffered no effect at all. More recently, a series of experiments on guinea-pigs produced the same dramatic result when they received a second injection of dog-serum.’

‘You
have
been busy, Sergeant.’

‘So the German doctors now believe that the acute respiratory shock in their patients was a similar reaction. The patients who died reacted to the vaccine, as you suggest, but some two weeks before receiving the injection they had become sensitised—is that the word?—to eggs, perhaps by eating them in some form, possibly even in a cake. When they were injected with the vaccine a fortnight later, the effect was as sudden and violent as if they had been given strychnine—except, of course, that the post mortem examination showed only the kinds of symptoms associated with death from chronic asthma.’

‘Oh, it’s eggs, is it?’ said Prothero. ‘I murdered my son with a boiled egg, did I—or was it a Madeira cake?’

‘If you’ll kindly allow me to go on,’ said Cribb, ‘you’ll see that I’m suggesting no such thing. People can be sensitive to other things besides eggs. You’ll allow that asthma results from reactions to certain substances and emanations?’

‘I can hardly deny it, having written a paper on the subject. Hay, pollen, ipecacuanha, bedfeathers, house-dust. A patient may be affected by any one of these, or something else. My son was sensitive to pollen.’

‘Really, sir?’ said Cribb. ‘Now suppose an asthma patient were discovered to be vulnerable to one of the substances you mention, rather as those Germans were sensitive to egg-white, and someone injected them with a small amount of the substance. What would the result be, do you think?’

‘Quite neutral, I should think. The substances affect the breathing, not the blood.’

‘Ah, but what if a second injection were given two weeks later?’

‘That would be a dangerous thing to try, Sergeant. It might well result in the phenomenon you have described.’ Prothero leaned forward across the table, ‘But if that was how it happened, you would have found a recent injection-mark on my son’s body. There was none—in spite of the inordinately careful examination made by the doctors at the post mortem.’

‘That’s where my theory foundered,’ said Cribb, ‘until I took professional advice. I put the case to my Harley Street specialist—hypothetically, of course, with no names mentioned. If a man with the specialised knowledge of substances that cause asthma and similar conditions were to take it into his head to kill another human being, I said, and chose a victim with a known sensitivity to, say, pollen, and a history of asthma, how would he induce the phenomenon known as acute respiratory shock? By grinding the pollen to a fine powder, said my adviser and then taking a very small amount, as little as a tenth of a milligram, and injecting it into the victim, perhaps secreted in some other substance administered in the course of treatment. Then if two weeks later he were suddenly exposed to a slightly larger quantity of the substance, say a milligram, he would die within five minutes. The amounts involved would be so small as to be impossible to detect in a post mortem. Did the second quantity of the substance have to be introduced by means of an injection, I asked? No, said he, certain substances are readily absorbed by skin tissue—nettle leaf irritant, for example, or pollen.’

‘This is all very plausible,’ said Prothero, ‘but when Guy died we were not in a bed of nettles, Sergeant, nor were we coating ourselves with pollen in the hotel garden. So far as I can recollect, there were not even any flowers in the lounge.’

‘I established that, sir. Went over everything I could think of until I was ready to give up. Then, as sometimes happens, I was thinking of something quite unconnected with the case, when the very thing I needed to know flashed across my mind. It was the statement the inspector made after I arrived and found you both there with Guy’s body. He
told
me the answer, and I was too damned unreceptive to accept it. What were his words, sir?—
“it seemed
at first to be the consequence of an over-enthusiastic inhalation of snuff.” That’s how you did it, Dr. Prothero. The pollen was in the boy’s snuff-box. One inhalation was enough to kill him. You’d mixed it with the snuff that morning knowing Guy wouldn’t take any on the ride, but would probably inhale it after lunch.’

‘You’ve had the contents of the snuff-box analysed, I have no doubt,’ said Prothero.

‘I have, sir, and as you very well know there ain’t a microscope invented with sufficient power to detect a quantity of pollen as small as that, nor a chemical test to prove its presence. It’s as neat a way of ending a fellow-human’s life as I’ve ever come across. A doctor’s way.’

‘A father’s,’ said Prothero, after a pause, ‘and not neat, Sergeant.’

‘The boy would have killed again if he had lived,’ said Cribb. In their context the words were reassuring. For the first time all pretence between the two men had been abandoned. They observed each other with candour, if not respect.

‘There is a saying of Hippocrates, the founder of our profession,’ said Prothero, ‘“Extreme remedies are most appropriate for extreme diseases”. Believe me when I tell you that I did all I could for Guy while he was alive. At the last, I had to ask myself what future there was for him. I know of other cases, Sergeant, poor wretches with the same dreadful impulse for violence who are kept behind locked doors by devoted parents. Can you imagine what will happen when one of them one day finds a way to slip the latch—for they are intelligent beings as Guy was? The mayhem and the carnage will be beyond belief, Sergeant, striking terror into people’s hearts long after the poor demented creature is recaptured by the police or his wretched family. Am I exaggerating?’

‘I hope so, sir,’ said Cribb quietly. ‘I think we’d better move in the direction of the station.’

Prothero raised his eyebrows questioningly. ‘Railway—or police?’

‘I’d never be able to prove my case in court,’ said Cribb with a slight smile. ‘Damned lawyers aren’t going to get a conviction out of nothing more substantial than an extra week in Brighton . . . Unless you’ve decided to make a confession. But, as I said, I didn’t bring a man with me, or the handcuffs, and it’s devilish hard to hear anything anyone says on those confounded trains. I think we’ve just time to catch that 4.23.’

Albert Moscrop finished polishing the latest example of his handiwork, a small, brass telescope with a magnification of four diameters. It represented some three weeks’ work, mainly in the evenings, after the shop was closed. He had begun on the day when he had read the newspaper report of the inquest on Bridget. She had been murdered, it had said, by a person or persons unknown, but it was understood that the police had indicated that there was nothing to be gained from further inquiries into the case.

He snapped the telescope shut and placed it on the tissue paper in a narrow wooden box on the table in front of him, making sure that the engraved name ‘Jason’ was uppermost. Then he closed the box, wrapped it, addressed it and affixed a stamp. As an afterthought, before he took it to the post-office, he turned the parcel over and wrote on the reverse, in small, neat letters,
Eastbourne next year.
