I had a meal at a Sikh restaurant after wandering around the city and then went to the railway station to buy my ticket on the Frontier Mail to Delhi. The man at Reservations put me on the waiting list and told me there was 'a 98 per cent chance' that I would get a berth, but that I would have to wait until half-past four for a confirmation. Indian railway stations are wonderful places for killing time in, and they are like scale models of Indian society, with its divisions of caste, class, and sex: SECOND-CLASS LADIES’ WATING ROOM, BEARERS’ ENTRANCE, THIRD-CLASS EXIT, FIRST-CLASS TOILET, VEGETARIAN RESTAURANT, NON-VEGETARIAN RESTAURANT, RETIRING ROOMS, CLOAKROOM, nd the whole range of occupations on office signboards, from the tiny one saying sweeper, to the neatest of all, STATION-MASTEDR. A steam locomotive was belching smoke at one of the platforms. I crossed over and as I snapped a picture a Sikh appeared on the footplate and asked me to send him a print. I said I would. He asked me where I was going, and when I told him I was taking the Frontier Mail he said, 'You have so many hours to wait. Come with me. Get in this bogie' – he pointed to the first car – 'and at the first station you can come in here and ride with me.'

'I'm afraid I'll miss my train.'

'You will not,' he said. 'Without fail.' He said this precisely, as if remembering an English lesson.

'I don't have a ticket.'

'No one is having a ticket. They are all cheating!'

So I climbed aboard and at the first station joined him in the cab. The train was going to Atari, on the Pakistan border, sixteen miles away. I had always wanted to ride in the engine of a steam locomotive, but this trip was badly timed. We left just at sunset and as I was wearing my prescription sunglasses – my other pair was in my suitcase in the station cloakroom – I could not see a thing. I held on, blind as a bat, sweating in the heat from the firebox. The Sikh shouted explanations of what he was doing, pulling levers, bringing up the pressure, spinning knobs, and dodging the coal shoveller. The

noise and the heat prevented me from taking any pleasure in this two-hour jaunt, and I suppose I must have looked dispirited because the Sikh was anxious to amuse me by blowing the whistle. Every time he did it the train seemed to slow down.

My face and arms were flecked with soot from the ride to Atari. On the Frontier Mail this was no problem, and I had the enjoyable experience that humid evening of taking a cold shower, squatting on my heels under the burbling pipe, as the train tore through the Punjab to Delhi.

I returned to my compartment to find a young man sitting on my berth. He greeted me in an accent I could not quite place, partly because he lisped and also because his appearance was somewhat bizarre. His hair, parted in the middle, reached below his shoulders; his thin arms were sheathed in tight sleeves and he wore three rings with large orange stones on each hand, bracelets of various kinds and a necklace of white shells. His face frightened me: it was that corpselike face of lunacy or a fatal illness, with sunken eyes and cheeks, deeply lined, bloodless, narrow, and white. He had a cowering stare, and as he watched me – I was still dripping from my shower – he played with a small leather purse. He said his name was Hermann; he was going to Delhi. He had bribed the conductor so that he could travel with a European. He didn't want to be in a compartment with an Indian – there might be trouble. He hoped I understood.

'Of course,' I said. 'But do you feel all right?'

'I have been sick – four days in Amritsar I have been in the hospital, and in Quetta also. I was so nervous. The doctors take tests and they give me this medicine, but it does no good. I don't sleep, I don't eat -just maybe glass of milk and piece of bread. I fly to Amritsar from Lahore. I was so sick in Lahore – three days in hospital and in Quetta two days. I cross Baluchistan. Yazd, you know Yazd? It is a terrible place. Two nights I am there and I am on the bus two days from Teheran. I cannot sleep. Every five hours the bus stops and I take some tea and a little melon. I am sick. The people say, "Why you don't talk – are you angry?" But I say, "No, not angry, but sick – "'

This was the way he spoke, in long lisped passages, interrupting himself, repeating that he was sick in a voice that was monotonously apologetic. He was German and had been a sailor, a deck hand on a German ship, then a steward on a Finnish one. He had sailed for seven years and had been to the States – 'Yes, to every country,' he said, 'but only for a few hours.' He loved ships, but he couldn't sail any more. I asked why. 'Hepatitis,' he said, giving it a German pronunciation. He caught it in Indonesia and was in the hospital for weeks. He had never managed to shake it off: he still needed tests. He'd had one in Amritsar. 'People say to me, "Your face is sick." I know my face is sick, but I cannot eat.'

His face was ghastly, and he was trembling. 'Are you taking any medicine?'

'No.' He shook his head. 'I take this.' He opened the leather purse he had been smoothing with his scrawny fingers and took out a cellophane envelope. He peeled the cellophane away and showed me a wad of brown sticky stuff, like a flattened plug of English toffee.

'What is it?'

'Opium,' he said. 'I take it in little balls.'

His lisp made 'balls' moistly vicious.

'I am a yunk.' He broke off a piece of opium and rolled it between his fingers, slowly making it a pellet.

'A junkie?'

'Yes, I take needle. See my arms.'

He locked the compartment door and pulled the curtain across the window. He rolled up his left sleeve. His arm appalled me: each vein was clearly defined by dark bruised scars of needle marks, thick welts that made the veins into black cords. He touched his arm shyly, as if it didn't belong to him and said, 'I cannot get heroin. In Lahore I am not feeling so well. I stay in hospital but still I am weak and nervous. The people are making noise and it is so hot. I don't know what I can do. So I escape and I walk down the street. A Pakistani says to me he has some morphine. I go with him and he shows me. It is good – German morphine. He asks me for one hundred and fifty rupees. I give him and take an injection. That is how I get to Amritsar. But in Amritsar I get very sick and I cannot get any more of morphine. So I take this – ' He patted his right pocket and took out a cake of hashish, roughly the size of the opium blob, but dry and cracked. 'Or I smoke this – ' He withdrew a little sack of marijuana.

I told him that with his budget of drugs he was lucky to have got into India. At the border post I had seen an Indian customs official ask a boy to drop his jeans.

'Yes,' said Hermann. 'I am so nervous! The man asks me do I have pot and I say no. Do I smoke it? I say, yes, sometimes, but he doesn't look at my luggages. If I am nervous I can hide it in secret places.'

'Then I suppose you don't have anything to worry about.'

'No, I am hot and nervous always.'

'But you can hide your drugs.'

'I can even throw them away and buy more,' he said. 'But my arms! If they see my arms they know. I have to hide my arms always.' He pushed his sleeves up and looked again at the long dark scars.

He told me how it was that he had come to India. In Hanover, he decided to cure himself of his heroin habit. He registered as an addict and entered a rehabilitation centre – he called it 'The Release' – where he was given 700 Deutsche Marks a month and a daily glass of methadone. In return for this he helped clean the centre. He never went out; he was afraid that if he did he would meet someone who'd sell him heroin. But an odd thing happened: by staying in he rarely spent his monthly allowance, and he found that at the end of a year he had saved quite a lot of money – enough to live on in India for six months or more. So he picked up and left, just like that, on a charter flight to Teheran, where his withdrawal symptoms began.
