‘Well, yes. But I daresay we shall find it some day. It can’t be anything very out-of-the-way, can it? I mean, there’s an awful lot of it knocking about. The trouble is, one doesn’t seem to be able to find it by chemical analysis. If one could, you know, it would probably turn out to be something quite ordinary, and then one could make it.’
‘The lost formula of Rossum’s Universal Robots, eh?’
‘Very likely,’ said Leader, ‘that’s a play, isn’t it? I never go to high-brow plays. All rot, you know — more in your line. But there it is. Analyse you and you’re just so much dead matter. Analyse toadstools, and you get this muscarine stuff. Makes one think a bit less of the marvels of Nature, don’t it?’
‘Except,’ said Munting, who had by now mounted on his usual hobby-horse, ‘except for the small accident of Life, which is, as you say, a triviality, no doubt, but yet—’
I interrupted him.
‘We don’t want to waste Mr Leader’s time with metaphysics.’
‘No,’ said Munting, obstinately, ‘but what I want to know—’
A tremendous clattering of feet in the corridor heralded the throwing open of the door and the irruption of a large number of young men in overalls.
‘Oh, Lord,’ said Leader, ‘we’ll have to clear out.’ He looked at his watch. ‘I say, do you mind if I barge off? There’s a demonstration I’ve simply got to attend. Nuisance, but I’m rather behind with Dimmock’s subjects. Must mug it up somehow. Awfully pleased to have seen you. Can you find your way out?’
‘Just a moment,’ said Munting. ‘You remember the fellow I brought with me last year — Lathom — the artist?’
‘Yes, of course — the fellow who was so keen on poisons. Asked such a lot of questions about the right dose, and was so struck with our synthetic stuff. Didn’t seem able to get over the fact that you couldn’t distinguish artificial muscarine from the natural product by chemical analysis. Very intelligent bloke I thought he was — for an artist. I remember him perfectly. Why?’
‘Have you seen anything of him since?’
‘No. Why?’
‘I just wondered. He said something once about looking you up.’
‘Well, he didn’t. Perhaps he came in the vac. There’s nobody here then, except the swots and the dunces trying to cram themselves for the exams. Tell him to come in term-time. I really must buzz along. I say, come and feed one night, won’t you?’
Munting promised to do so, and Leader escaped, cannoning violently into the demonstrator as he dashed out. We followed, not wishing to be caught and interrogated.
‘That was Benton,’ said Munting, looking back at the closing door. ‘I wish we could have had a word with him. If Leader—’
‘About the origin of life, I suppose? You’re cracked about the origin of life. It’s the origin of death we’re investigating. We’ve got what we came for. It’s clear enough that anybody might have walked in and helped himself to a dose of that stuff. Look at those places we went into. No one to stop us — and it’s term-time, too. In the vac. the place is absolutely deserted. If Lathom was over here in the vac. — and he was. Don’t you remember those letters of Margaret Harrison’s? He was here in July.’
‘Yes,’ agreed Munting, thoughtfully. ‘Yes, I quite see that. But the difficulty is to prove it. Just because it’s so easy to get in, it’s a million to one against anybody having noticed you. And you can’t expect a jury to accept a vague possibility like that. If there was any analysable difference between natural and synthetic muscarine, then, of course, you would have something genuine to go upon. Because it would be quite impossible to eat synthetic muscarine by accident — except in a laboratory. But apparently there is no difference.’
This sobered me. I had been feeling that we were well on the way to solve the problem. But now I saw very clearly that we were just as far away as ever. No jury in the world would accept this involved and unsubstantiated theory. True, people are ready enough to believe that an adulterer is very likely a murderer as well. But if it comes to the question of probability, which will they rather believe? That a man elaborately stole a rare and incomprehensible laboratorly product which none of them have ever heard of, and elaborately administered it under involved and peculiar circumstances? Or that an eccentric experimenter with ‘unnatural’ foods accidentally poisoned himself with toadstools? The answer is obvious.
Moreover, to obtain a conviction, there must be no doubt possible. The murder theory must be overwhelmingly more likely than the accident theory. Judges are careful to point this out.
I was as certain that Lathom had poisoned my father with synthetic muscarine as that I was alive. But I began to be equally certain that Lathom had hit upon a method of murder that was utterly and completely proof against proof.
52. Statement of John Munting
[Additional and concluding portion.]
This damned business of Lathom’s.
People write books about murders, and the nice young men and women in them enjoy the job of detecting. It is a good game and I like reading the books. But the emotions of the nice young people are so well-regulated, or so perfunctory, or something. They don’t feel like worms and get put off their dinners when they have succeeded in squeezing a damaging admission out of a friend. They don’t seem to suffer from fits of retching terror for fear they should find out something definite. Nor, while struggling with these complicated miseries, do they ever have to fulfil contracts with publishers. Sometimes they are filled with a stern sorrow — a nice, Brutus-like sentiment. I envy their nerves.
My nerves went back on me about the time of our visit to St Anthony’s. I took a kind of hysterical pleasure in pointing out that we had no proof of the murder. I didn’t want proof. I didn’t want to know. It was like writing one of those horrible letters which call for a decisive answer one way or another. You post it and wait, and you know that one morning you will see your correspondent’s handwriting on an envelope, and feel as hollow as a piece of bamboo. And you wait. Nothing comes. And after a time you say, ‘It’s been lost in the post. Now I need not know. Not now, at any rate, I can still pretend that it’s all right. Nothing will happen today. I can eat my dinner and listen to the wireless — and perhaps it will go on like that for ever.’
The answer to the Lathom problem seemed to have been lost in the post. We did not talk about it at home. My wife knew that I winced from it. It made other subjects impossible, too. Women, for instance, and the way they influence their lovers — we would start as far off as Gordon Craig’s theatre-masks or Gryll Grange and Lord Curryfin’s echeia, and before we had gone far, the figure of Clytemnestra would come bobbing over the horizon, and I would be talking hurriedly, dismissing it, rushing into technicalities about epode and stasimen, or about the chorus or the machines — anything. Or if Elizabeth merely asked what we should have for dinner, it seemed difficult to think of anything that was not flavoured with mushrooms or founded on beef-stock. We lived for a whole week on fish once, so sensitive did our minds become.
I got over it, more or less, after a time and, mercifully, Lathom let me alone. It was not till March that a faint reminding echo of the thing sounded faintly over the breakfast-table. I got a note from Mr Perry, the parson to whom I had once lent a volume of Eddington. At the sight of his name I got a kind of painful twitching in the sore place.
The note was to invite me to dinner. An old college friend of his, the extremely celebrated Professor Hoskyns, was coming over to spend the evening with him. Hoskyns is, of course, a very brilliant physicist, and Perry thought it would interest me to meet him. One or two other people were coming as well. If I could put up with a very simple meal, he thought we should enjoy a really enjoyable talk.
