But when the War was over he hankered for a quiet life, so he bought a practice in the deepest and greenest corner of England. He said his motive was the same as that which in the rackety Middle Ages made men retire into monasteries; he wanted quiet and leisure to consider his soul. Quiet he may have found, but uncommon little leisure, for I never heard of a country doctor that toiled at his job as he did. He would pay three visits a day to a panel patient, which shows the kind of fellow he was; and he would be out in the small hours at the birth of a gipsy child under a hedge. He was a first-class man in his profession, and kept abreast of it, but doctoring was only one of a thousand interests. I never met a chap with such an insatiable curiosity about everything in heaven and earth. He lived in two rooms in a farmhouse some four miles from us, and I dare say he had several thousand books about him. All day, and often half the night, he would scour the country in his little run-about car, and yet, when he would drop in to see me and have a drink after maybe twenty visits, he was as full of beans as if he had just got out of bed. Nothing came amiss to him in talk—birds, beasts, flowers, books, politics, religion—everything in the world except himself. He was the best sort of company, for behind all his quickness and cleverness, you felt that he was solid bar-gold. But for him I should have taken root in the soil and put out shoots, for I have a fine natural talent for vegetating. Mary strongly approved of him and Peter John adored him.
He was in tremendous spirits that evening, and for once in a way gave us reminiscences of his past. He told us about the people he badly wanted to see again; an Irish Spaniard up in the north of the Argentine who had for cattle-men a most murderous brand of native from the mountains, whom he used to keep in good humour by arranging fights every Sunday, he himself taking on the survivor with his fists and always knocking him out; a Scots trader from Hankow who had turned Buddhist priest and intoned his prayers with a strong Glasgow accent; and most of all a Malay pirate, who, he said, was a sort of St. Francis with beasts, though a perfect Nero with his fellow-men. That took him to Central Asia, and he observed that if ever he left England again he would make for those parts, since they were the refuge of all the superior rascality of creation. He had a notion that something very odd might happen there in the long run. "Think of it!" he cried. "All the places with names like spells—Bokhara, Samarkand—run by seedy little gangs of communist Jews. It won't go on for ever. Some day a new Genghis Khan or a Timour will be thrown up out of the maelstrom. Europe is confused enough, but Asia is ancient Chaos."
After dinner we sat round the fire in the library, which I had modelled on Sir Walter Bullivant's room in his place on the Kennet, as I had promised myself seven years ago. I had meant it for my own room where I could write and read and smoke, but Mary would not allow it. She had a jolly panelled sitting-room of her own upstairs, which she rarely entered; but though I chased her away, she was like a hen in a garden and always came back, so that presently she had staked out a claim on the other side of my writing-table. I have the old hunter's notion of order, but it was useless to strive with Mary, so now my desk was littered with her letters and needlework, and Peter John's toys and picture-books were stacked in the cabinet where I kept my fly-books, and Peter John himself used to make a kraal every morning inside an up-turned stool on the hearth-rug.
It was a cold night and very pleasant by the fireside, where some scented logs from an old pear-tree were burning. The doctor picked up a detective novel I had been reading, and glanced at the title-page.
"I can read most things," he said, "but it beats me how you waste time over such stuff. These shockers are too easy, Dick. You could invent better ones for yourself."
"Not I. I call that a dashed ingenious yarn. I can't think how the fellow does it."
"Quite simple. The author writes the story inductively, and the reader follows it deductively. Do you see what I mean?"
"Not a bit," I replied.
"Look here. I want to write a shocker, so I begin by fixing on one or two facts which have no sort of obvious connection."
"For example?"
"Well, imagine anything you like. Let us take three things a long way apart—" He paused for a second to consider—"say, an old blind woman spinning in the Western Highlands, a barn in a Norwegian saeter, and a little curiosity shop in North London kept by a Jew with a dyed beard. Not much connection between the three? You invent a connection—simple enough if you have any imagination, and you weave all three into the yarn. The reader, who knows nothing about the three at the start, is puzzled and intrigued and, if the story is well arranged, finally satisfied. He is pleased with the ingenuity of the solution, for he doesn't realise that the author fixed upon the solution first, and then invented a problem to suit it."
"I see," I said. "You've gone and taken the gilt off my favourite light reading. I won't be able any more to marvel at the writer's cleverness."
"I've another objection to the stuff—it's not ingenious enough, or rather it doesn't take account of the infernal complexity of life. It might have been all right twenty years ago, when most people argued and behaved fairly logically. But they don't nowadays. Have you ever realised, Dick, the amount of stark craziness that the War has left in the world?"
Mary, who was sitting sewing under a lamp, raised her head and laughed.
Greenslade's face had become serious. "I can speak about it frankly here, for you two are almost the only completely sane people I know. Well, as a pathologist, I'm fairly staggered. I hardly meet a soul who hasn't got some slight kink in his brain as a consequence of the last seven years. With most people it's rather a pleasant kink—they're less settled in their grooves, and they see the comic side of things quicker, and are readier for adventure. But with some it's pukka madness, and that means crime. Now, how are you going to write detective stories about that kind of world on the old lines? You can take nothing for granted, as you once could, and your argus-eyed, lightning-brained expert has nothing solid with which to build his foundations."
I observed that the poor old War seemed to be getting blamed for a good deal that I was taught in my childhood was due to original sin.
"Oh, I'm not questioning your Calvinism. Original sin is always there, but the meaning of civilisation was that we had got it battened down under hatches, whereas now it's getting its head up. But it isn't only sin. It's a dislocation of the mechanism of human reasoning, a general loosening of screws. Oddly enough, in spite of parrot-talk about shell-shock, the men who fought suffer less from it on the whole than other people. The classes that shirked the War are the worst—you see it in Ireland. Every doctor nowadays has got to be a bit of a mental pathologist. As I say, you can hardly take anything for granted, and if you want detective stories that are not childish fantasy you'll have to invent a new kind. Better try your hand, Dick."
