I’m conscious now that what I was doing was “playing God,” re-imagining my world and making it more exciting and evocative than the reality. It’s what all writers do, and already I was starting to feel like a writer. My parents weren’t great readers, and there were few books in the house, but I was drawn to stories. I would haunt the town’s library and soon started borrowing “adult” titles, meaning books whose films I wasn’t old enough to see at the cinema. At age thirteen, I was reading Mario Puzo’s The Godfather and Anthony Burgess’s A Clockwork Orange. By fourteen it was One Flew Over the Cuckoo’s Nest. I also came across Ernest Tidyman’s Shaft books (and would eventually give Rebus the forename John as a nod to “black private dick” John Shaft). I checked the TV schedules to see if there were any programs about books and would watch them, deciding that I really needed to read this guy Solzhenitsyn (I ended up struggling through volume two of The Gulag Archipelago). Later on I would fail to finish Dante’s Inferno but be thrilled by Ian McEwan’s first book of short stories.

My best subject in high school was English. I always enjoyed writing essays (which were in effect short stories). One was called “Paradox” and concerned a man who seemed to be president of the United States but turned out to be an inmate in an insane asylum. My teacher liked it but wondered why I’d chosen that particular title. It was the name of a Hawkwind song, I told him, and I just liked the sound and look of the word.

“And no, sir, I’ve no idea what it means.”

For another essay, we were given the phrase “Dark they were and golden-eyed” and told to use it as our starting point. I wrote about two parents searching a house filled with drug addicts, seeking their errant son.

Words were a passion of mine. I would do crosswords and flick through the dictionary, noting interesting words (including, after the exchange noted above, paradox). And those song lyrics for the Amoebas had become poems, one of which I entered for a national competition. It was called “Euthanasia” (another of those great-sounding words) and was runner-up. When my success was noted in the local newspaper, my parents learned for the first time that I was writing poetry. I hadn’t dared tell anyone until then. (Later, I would learn that Muriel Spark’s first publication had also been a prize-winning school poem.)

I’d always been a successful chameleon, playing the part of fitting in. I played soccer (badly) and had a bicycle. I hung around the street corners with the tough kids. But when a rumble started, I’d be on the periphery of the action, taking it all in without getting involved. When I went home, I’d head for my bedroom and write poems about the fights, the booze, the first sexual fumblings, and then my notebook would go back underneath my bed, hidden from view.

Okay, so I’m seventeen now, and I want nothing more than to be an accountant.

See, nobody in my family has been to university, but it seems I’m brainy and it’s expected I’ll go. And if you’re working-class, you go to university to escape your roots-to get a good career: doctor, lawyer, dentist, architect…

I had an uncle in England, and he owned his own house (unlike my parents) and had a flash car (neither of my parents could even drive). Our summer holidays were spent at seaside resorts in Scotland and England, or in a cramped trailer twenty miles north of my hometown. My uncle always seemed to have a tan from foreign holidays. He was the most successful man I knew, and I wanted the same for myself.

Problem was, I wasn’t very good at math. And I was growing to be ever more in thrall to books and to writing. I’d cranked out a couple of “novels” (probably twenty pages long, scribbled on jotters stolen from my school). The first was about a teenager who feels misunderstood so runs away from home and ends up in London, where he is ground down by life before eventually committing suicide. The second was a retelling of Lord of the Flies, set in my high school. It was starting to dawn on me: why the hell was I thinking of going to university to study a subject I had no real interest in? I broke the news to my parents and watched their shoulders sag. They were in their late fifties by this point, not too far from retirement. What, they asked, would I do with a degree in English? It was a fair question.

“Teach” was all I could think to reply.

I started looking at possible universities. St. Andrews was the closest, but I liked reading modern American and British novels, and “modern” at St. Andrews meant John Milton. I knew this because I’d asked. Edinburgh, however, had a course in “American literature,” so I applied there and was eventually accepted. How well did I know the city? Hardly at all. I’d lived all my life about twenty miles north, but the family seldom ventured that far. I remember being taken there to see a stage version of Peter Pan, and my mother once took me to the castle and a children’s museum. In my last couple of years at high school, I’d made occasional Saturday-afternoon forays with friends. But we would always stick to the same route, taking in all the available record shops, one radical bookshop (where porn, under the guise of “art books,” could be perused), and a couple of pubs where the bar staff had decided we weren’t underage enough to pose a problem.

Arriving in the city in October 1978 as a student was terrifying and exciting. The university had been unable to provide me with accommodation, so I was sharing a room with a school pal in a motel on the outskirts. I was quick to join the poetry and film societies; quick, too, to discover new pubs, live-music venues, and strip bars. I also joined a punk group (as singer and lyricist), so found a new outlet for my stanzas. And I was on the receiving end of a slew of rejection letters from magazines and newspapers.

The poetry society held weekly meetings. Hormonally charged young men (all the poets seemed to be male, the audience fifty-fifty) would recite odes of love lost, love unrequited, love from afar. My poems were a bit different. A typical opening might be:

Mutated machine-guns patrolling the subways

While glue-sniffing kids hang themselves in lift-shafts…

I had another poem called “Strappado” (a form of torture) and yet another telling the moving story of a husband who strangles his young wife on their honeymoon. Where was this stuff coming from? Why was I writing lyrics about addicts and killers and crucifixion? I can’t find anything in my early life to justify this apparent interest in the bizarre and the demonic. I even had an alter ego, a drifter called Kejan, who cropped up in several poems and who would usually be drinking absinthe in Paris or traversing the stews of Alexandria:

A foreign body in the bloodstream of Berne,

Kejan tips the remnants of tobacco

From the pack onto the paper,

His breath scattering the flakes

Onto the floor

To lie wriggling in the draught.

Kejan needs some air…

None of this, it goes without saying, was helping me get laid.

But I did get to meet a lot of “real” writers for the first time in my life. The poetry society had funding to bring one professional poet to do a reading each week, and afterward we would all go for a drink or nine, during which time the poets would attempt to sell us copies of their books and pamphlets while we’d be asking questions such as “How do I get published?” I soon learned that most poets don’t make a living writing but have to supplement their income with other work. I wondered if the same was true of fiction writers.

My poems were far from the Wordsworthian ideal of “emotion recollected in tranquillity.” They were narratives. My characters went places and did things, or things happened to them. (There were always consequences.) I started writing short stories, influenced by Ian McEwan, Jayne Anne Phillips, and anyone else I happened to be reading at the time. I was trying to find out two things: what I wanted to write about, and how to do the actual writing. It took me a while to realize that the thing I really wanted to write about was enveloping me and embracing me every step of the way and with each and every breath I took.
