'What do you think, old girl?' asked Bradshaw, whose pith helmet and safari suit were ideally suited to the hot Nebraskan summer. He was shorter than me by almost a head but led age-wise by four decades; his sun-dried skin and snowy-white moustache were a legacy of his many years in Colonial African Fiction: he had been the lead character in the twenty-three 'Commander Bradshaw' novels, last published in 1932 and last read in 1963. Many characters in fiction define themselves by their popularity, but not Commander Bradshaw. Having spent an adventurous and entirely fictional life defending British East Africa against a host of unlikely foes, and killing almost every animal it was possible to kill, he now enjoyed his retirement and was much in demand at Jurisfiction, where his fearlessness under fire and knowledge of the BookWorld made him one of the agency's greatest assets.

He was pointing at a weathered board that told us the small township not more than half a mile ahead hailed by the optimistic name of Providence and had a population of 2,387.

I shielded my eyes against the sun and looked around. A carpet of sage stretched all the way to the mountains less than five miles distant. The vegetation had a repetitive pattern that belied its fictional roots. The chaotic nature of the real world that gave us soft undulating hills and random patterns of forest and hedges was replaced within fiction by a landscape that relied on ordered repetitions of the author's initial description. In the make-believe world where I had made my home, a forest has only eight different trees, a beach five different pebbles, a sky twelve different clouds. A hedgerow repeated itself every eight feet, a mountain range every sixth peak. It hadn't bothered me that much to begin with but after two years living inside fiction I had begun to yearn for a world where every tree and rock and hill and cloud had its own unique shape and identity. And the sunsets. I missed them most of all. Even the best-described ones couldn't hold a candle to a real one. I yearned to witness once again the delicate hues of the sky as the sun dipped below the horizon. From red to orange, to pink, to blue, to navy, to black.

Bradshaw looked across at me and raised an eyebrow quizzically. As 'The Bellman' — the head of Jurisfiction — I shouldn't really be out on assignment at all, but I was never much of a desk jockey and capturing the Minotaur was important. He had killed one of our own, and that made it unfinished business.

During the past week we had searched unsuccessfully through six civil war epics, three frontier stories, twenty-eight high-quality Westerns and ninety-seven dubiously penned novellas before finding ourselves within Death at Double-X Ranch, right on the outer rim of what might be described as acceptably written prose. We had drawn a blank in every single book. No minotaur, nor even the merest whiff of one, and believe me, they can whiff.

'A possibility?' asked Bradshaw, pointing at the Providence sign.

'We'll give it a try,' I replied, slipping on a pair of dark glasses and consulting my list of potential minotaur hiding places. 'If we draw a blank we'll stop for lunch before heading off into The Oklahoma Kid.'

Bradshaw nodded, opened the breech of the hunting rifle he was carrying and slipped in a cartridge. It was a conventional weapon but loaded with unconventional ammunition. Our position as the policing agency within fiction gave us licensed access to abstract technology. One blast from the eraserhead in Bradshaw's rifle and the Minotaur would be reduced to the building blocks of his fictional existence: text and a bluish mist — all that is left when the bonds that link text to meaning are severed. Charges of cruelty failed to have any meaning when at the last Beast Census there were over a million almost identical minotaurs, all safely within the hundreds of books, graphic novels and urns that featured him. Ours was different — an escapee. A PageRunner.

As we walked closer the sounds of a busy Nebraskan frontier town reached our ears. A new building was being erected and the hammering of nails into lumber punctuated the clop of horses' hoofs, the clink of harnesses and the rumble of cartwheels on compacted earth. The metallic ring of the blacksmith's hammer mixed with the distant tones of a choir from the clapboard church, and all about was the general conversational hubbub of busy townsfolk. We reached the corner of Eckley's Livery Stables and peered cautiously down the main street.

Providence as we now saw it was happily enjoying the uninterrupted backstory, patiently awaiting the protagonist's arrival in two pages' time. Blundering into the main narrative thread and finding ourselves included within the story was not something we cared to do, and since the Minotaur avoided the primary storyline for fear of discovery we were likely to stumble across him only in places like this. But if, for any reason, the story did come anywhere near, I would be warned — I had a Narrative Proximity Device in my pocket that would sound an alarm if the thread came too close. We could hide ourselves until it passed by.

A horse trotted past as we stepped up on to the creaky decking that ran along the front of the saloon. I stopped Bradshaw when we got to the swing-doors just as the town drunk was thrown out into the road. The bartender walked out after him, wiping his hands on a linen cloth.

'And don't come back till you can pay your way!' he yelled, glancing at us both suspiciously.

I showed the barkeeper my Jurisfiction badge as Bradshaw kept a vigilant lookout. The whole Western genre had far too many gunslingers for its own good; there had been some confusion over the numbers required on the order form when the genre was inaugurated. Working in Westerns could sometimes entail up to twenty-nine gunfights an hour.

'Jurisfiction,' I told him. 'This is Bradshaw, I'm Next. We're looking for the Minotaur.'

The barkeeper stared at me coldly.

'Think you's in the wrong genre, partner,' he said.

All characters or Generics within a book are graded A to D, one through ten. A-grades are the Gatsbys and Jane Eyres, D-grades the grunts who make up street scenes and crowded rooms. The barkeeper had lines so he was probably a C-2. Smart enough to get answers from but not smart enough to have much character latitude.

'He might be using the alias Norman Johnson,' I went on, showing him a photo. 'Tall, body of a man, head of a bull, likes to eat people?'

'Can't help you,' he said, shaking his head slowly as he peered at the photo.

'How about any outbreaks of Slapstick?' asked Bradshaw. 'Boxing glove popping out of a box, sixteen-ton weights dropping on people, that sort of thing?'

The barkeeper laughed. 'Ain’t seen no weights droppin’ on nobody, but I heard tell the sheriff got hit in the face with a frying pan last Toosday.'

Bradshaw and I exchanged glances.

'Where do we find the sheriff?' I asked.

We followed the barkeeper's directions and walked along the wooden decking past a barber shop and two grizzled prospectors who were talking animatedly in authentic frontier gibberish. I stopped Bradshaw when we got to an alleyway. There was a gunfight in progress. Or at least, there would have been a gunfight had not some dispute arisen over the times allocated for their respective showdowns. Both sets of gunmen — two dressed in light-coloured clothes, two in dark, with low-slung gunbelts decorated with rows of shiny cartridges — were arguing over their gunfight time slots as two identical ladyfolk looked on anxiously. The town mayor intervened and told them that if there was any more arguments they would both lose their slot times and would have to come back tomorrow, so they reluctantly agreed to toss a coin. The winners of the toss scampered into the main street as everyone dutifully ran for cover. They squared up to one another, hands hovering over their Colt .455 at twenty paces. There was a flurry of action, two loud detonations and one of the gunmen in black hit the dirt while the victor looked on grimly, his opponent's shot having dramatically only removed his hat. His lady rushed up to hug him as he reholstered his revolver with a flourish.
