They set off towards the next pyramid. Gern led the way, his face a picture, possibly one painted late at night by an artist who got his inspiration on prescription. Dil followed. He held his chest high. He'd always hoped to make his way in the world and here he was now, walking with kings.

Well. Lurching with kings.

It was another nice day in the high desert. It was always a nice day, if by nice you meant an air temperature like an oven and sand you could roast chestnuts on.

You Bastard ran fast, mainly to keep his feet off the ground for as long as possible. For a moment as they staggered up the hills outside the olive-tree'd, field-patchworked oasis around Ephebe, Teppic thought he saw the Unnamed as a tiny speck on the azure sea. But it might have been just a gleam on a wave.

Then he was over the crest, into a world of yellow and umber. For a while scrubby trees held on against the sand, but the sand won and marched triumphantly onwards, dune after dune.

The desert was not only hot, it was quiet. There were no birds, none of the susurration of organic creatures busily being alive. At night there might have been the whine of insects, but they were deep under the sand against the scorch of day, and the yellow sky and yellow sand became an anechoic chamber in which You Bastard's breath sounded like a steam-engine.

Teppic had learned many things since he first went forth from the Old Kingdom, and he was about to learn one more. All authorities agree that when crossing the scorching desert it is a good idea to wear a hat.

You Bastard settled into the shambling trot that a prime racing camel can keep up for hours.

After a couple of miles Teppic saw a column of dust behind the next dune. Eventually they came up behind the main body of the Ephebian army, swinging along around half-a-dozen battle elephants, their helmet plumes waving in the oven breeze. They cheered on general principles as Teppic went past.

Battle elephants! Teppic groaned. Tsort went in for battle elephants, too. Battle elephants were the fashion lately. They weren't much good for anything except trampling on their own troops when they inevitably panicked, so the military minds on both sides had responded by breeding bigger elephants. Elephants were impressive.

For some reason, many of these elephants were towing great carts full of timber.

He jogged onwards as the sun wound higher and, and this was unusual, blue and purple dots began to pinwheel gently across the horizon.

Another strange thing was happening. The camel seemed to be trotting across the sky. Perhaps this had something to do with the ringing noise in his ears.

Should he stop? But then the camel might fall off.

It was long past noon when You Bastard staggered into the baking shade of the limestone outcrop which had once marked the edge of the valley, and collapsed very slowly into the sand. Teppic rolled off.

A detachment of Ephebians were staring across the narrow space towards a very similar number of Tsorteans on the other side. Occasionally, for the look of the thing, one of them waved a spear.

When Teppic opened his eyes it was to see the fearsome bronze masks of several Ephebian soldiers peering down at him. Their metal mouths were locked in sneers of terrible disdain. Their shining eyebrows were twisted in mortal anger.

One of them said, 'He's coming round, sarge.'

A metal face like the anger of the elements came closer, filling Teppic's vision.

'We've been out without our hat, haven't we, sonny boy,' it said, in a cheery voice that echoed oddly inside the metal. 'In a hurry to get to grips with the enemy, were we?'

The sky wheeled around Teppic, but a thought bobbed into the frying pan of his mind, seized control of his vocal chords and croaked: 'The camel!'

'You ought to be put away, treating it like that,' said the sergeant, waggling a finger at him. 'Never seen one in such a state.'

'Don't let it have a drink!' Teppic sat bolt upright, great gongs clanging and hot, heavy fireworks going off inside his skull. The helmeted heads turned towards one another.

'Gods, he must have something really terrible against camels,' said one of them. Teppic staggered upright and lurched across the sand to You Bastard, who was trying to work out the complex equation which would allow him to get to his feet. His tongue was hanging out, and he was not feeling well.

A camel in distress isn't a shy creature. It doesn't hang around in bars, nursing a solitary drink. It doesn't phone up old friends and sob at them. It doesn't mope, or write long soulful poems about Life and how dreadful it is when seen from a bedsitter. It doesn't know what angst is.

All a camel has got is a pair of industrial-strength lungs and a voice like a herd of donkeys being chainsawed.

Teppic advanced through the blaring. You Bastard reared his head and turned it this way and that, triangulating. His eyes rolled madly as he did the camel trick of apparently looking at Teppic with his nostrils.

He spat.

He tried to spit.

Teppic grabbed his halter and pulled on it.
