HIS BREATH WAS damp and earthy. The old man had tuberous growths in his gut. Dr Gregor could palpate them with his palm. They were starchy, as tough as carrots. ‘There is some inflammation,’ he said. ‘Nothing to worry about. Rest is what you need.’ What was the point of alarming a man of eighty-two with an honest diagnosis, with hospitals, with surgery? He would be dead within the month. ‘Are you in any pain?’ The old man shook his head. The doctor prescribed warm olive oil to ‘ease the passage through your bowel’.
He did not die within the month. He lasted ten more months before he came to Dr Gregor’s clinic again. It was the spring of the drought. He looked as tough and sinewy as a man of half his age. Indeed, he looked a little younger than before, though he was eighty-three now.
‘Are you in any pain?’ the doctor asked again.
‘A little. Once in a while.’ When he bent to tie his boots, he explained, or tug at weeds, the hard knots in his stomach bunched against the waistband of his trousers. It was uncomfortable. What man of eighty-three could bend to touch his boots without a little pain?
‘I think I’d better take a look,’ the doctor said. He helped the old man onto the examination bed and turned him on his side, his face towards the wall. He pulled on a pair of disposable lubricated gloves. ‘Knees up. This shouldn’t take a second. Think of somewhere nice.’
The old man searched for somewhere nice. At first it was the modest garden where he now lived in town: the tiny square of lawn, the hem of evergreens, the single potted maple on the patio. But soon he settled on the larger piece of land that he had owned when he was younger, its trees, its stony paths, its dogged thistles, its flinty earth, the vegetables, which he would harvest on summer Sundays and bring up to the house in a trug.
The doctor did not have to penetrate too deeply beyond the sphincter to find the woody growths in his patient’s bowel. Perhaps they were elephantine polyps of some kind, and not a string of cancers. Perhaps they were benign. Clearly they caused no pain, except when the old man stooped to touch his toes. Dr Gregor pushed against the lowest tumour with his index finger. It did not seem attached, but moved freely. Its shape was odd. It was not symmetrical or funnelled, but complex, with extensions and recessions like the chambered plaster cast of an earth-roach burrow. ‘Have you examined your stool of late? Anything unusual? Any blood?’ The old man shook his head. Why would he want to examine his stool?
The doctor was not a sentimental or a squeamish man. He managed to work a couple of small ‘polyps’ loose. He put one in a lidded specimen tub and labelled it with a date and a reference for the laboratories. The other he put in a sterile bag with a little purified water. He was puzzled, but doctors are often puzzled. Let the laboratories give a name to it. He put his arm around the old man’s shoulders and took him to the door. ‘Warm olive oil,’ he said.
Laboratories can take a month to analyse and process specimens. Dr Gregor did not think the matter urgent enough to telephone for their report. The old man was fit for eighty-three. What was a month to him? They’d get their answers soon enough. In fact the old man died within three weeks of his last visit to the surgery. A sudden and unheralded stroke, too quick to experience. A neighbour called the doctor out one morning and led him to the body. His patient must have died the evening before. He’d been standing in his tiny garden with a hose. The grass and shrubs were green with care, despite the weeks of drought. The tap had been running all night long. The old man lay on his back in shallow water. Slugs were on his shirt and trousers, taking refuge from the flood. There was a smell — damp and earthy like the old man’s breath had been. It was the smell of vegetation. So that was that. He’d made a decent age and met a decent death.
The laboratories sent their report and their invoice. The old man’s specimen was described as ‘non-invasive’, ‘benign’, and ‘entirely vegetable: water 83 %; albuminoids 2 %; gum 9.1 %; sugar 4.2 %; inulin 1.1 %’. Dr Gregor held the ‘polyp’ he had kept up to the light in its sterile bag. It seemed more swollen. The inside of the bag was silvery with condensation. He paid the laboratory bill by cheque. A waste of time and money. He could not pass the costs on to a patient now. He put the swelling polyp on his windowsill. He did not like to part with it, now that the man was dead.
Encouraged by the heat and light and by the purified water, the vegetable grew a pair of tiny yellow horns. Its wrinkles flattened. Its extensions and recessions achieved a kind of nippling puberty. One horn pinkened, lengthened and uncurled. The old man’s polyp had a shoot. The doctor put it in a glass dish on a bed of damp toilet paper. He watered it each day. He gave it houseplant feed. Quite soon he had three green shoots and two more horns. Roots as thin as cotton thread clung to the damp paper. He had to pick a greenfly from its stem.
A patient — asked to lean against the windowsill while Dr Gregor checked her damaged vertebrae — recognized it as a tuber. Not a tumour, then?
‘I’ve never grown these ones myself,’ she said. ‘It’s root ginger, isn’t it? Or Jerusalem artichoke? What do they taste like? Does it smell?’
The doctor held it to his nose. The old man’s breath again.
‘You’ll have to pot it up,’ the patient said. ‘It won’t survive on that!’
The doctor sent his nurse out to the shops to buy a pot and some compost. He thumbed the polyp into the soil, and only damaged a couple of shoots. He put the plant outside the front door of his surgery. His patients dropped their cigarette ends into the pot, or spat into the soil. The soil flourished on bronchitis. It put up three good stems, with heavy leaves, and — in the summer — three inconspicuous yellow flowers at shoulder height. The old dears coming in for their pills didn’t have to bend to press their noses to the blooms. The yellow petals were busy with weevils. His patient’s diagnosis was confirmed by some of the many gardeners on the doctor’s list: they were Jerusalem artichokes — or Canadian potatoes as one man called them — not root ginger.
In September, the three stems and their leaves dried out and died. They broke away, and the pot became an ashtray, nothing else. In November, Dr Gregor found a moment to carry the pot through to the yard behind the surgery. He turned the soil out onto a plastic bag. He planned to wash the pot and plant a basil in it, or a daphne. Something colourful or evergreen for the steps. There were a dozen clusters of the old man’s polyps multiplying in the soil, a starchy kilo at the very least. The doctor picked them out and put them in the emptied pot. They smelled of soot. ‘More trouble than they’re worth,’ his nurse remarked. ‘Except in soup!’
That night, he took the crop to his apartment. He did not peel them or attempt to scrape them. They were too oddly shaped. He scrubbed half of them in warm water. He cooked them au gratin with bacon curls. His brother and his sister-in-law came for dinner. The Jerusalem artichokes, he said, were the gift of a patient: ‘He grew them himself.’ They tasted bland and floury. According to his sister-in-law, they would have benefited from a pinch of coriander, say, or more salt.
Dr Gregor was fond of his brother and his wife, but she was far too keen to give advice on what would benefit his life, his work, his apartment, his cooking. More salt. A dab of paint. A housekeeper. A bit of colour to his clothes. A holiday. A wife. ‘Why don’t you settle down?’ Or, ‘Find a woman for yourself. That nurse of yours is quite a decent sort.’
The doctor showed his brother and his wife to the door. He let them take the half-kilo of Jerusalem artichokes that had not been scrubbed and cooked. For their kitchen garden.
His guests were a little windy from their meal. Their breaths were damp and earthy. ‘They’re nice, but indigestible,’ his brother said.
‘Are you in any pain?’ Dr Gregor asked. ‘Take warm olive oil, to ease their passage through your bowels.’ He wondered if he should have said more about the artichokes, how natural, how death-defying and how benign they were.
The doctor’s brother dug the tubers into a trench of flinty earth, amongst the dogged thistles at the bottom of their garden. He put in lime and compost. In summer there were yellow flowers, and in autumn there were tubers by the kilo. On Sundays he would harvest them and bring his trug of starchy vegetables up into the house. They made the perfect Monday soup, which kept them warm and bilious in winter.
