Matatu was the last across, carrying Sean's clothing and his rifle, and immediately he was off again, like a wraith of the forest. Sean followed him with the agony of cold shuddering through his body and the sodden furs a heavy burden to add to the rifle and his pack.

A herd of buffalo crashed away through the forest ahead of them, and the bovine stink lingered in their nostrils long after they were gone. Once Sean had a glimpse of a huge antelope, ginger red with vertical white stripes down its heavy body and a head of magnificent spiral horns. It was a bongo. He would have charged one of his rich American clients $1000 for a shot at that rarest and most elusive of all antelopes, but it ghosted away into the bamboo and Matatu led them on without apparent purpose or direction, the spoor three hours cold behind them.

Then Matatu skirted one of the rare forest clearings and stopped again. He glanced back over his naked shoulder and grinned at Sean with the patent adoration of a hunting dog who acknowledges the most important being in its universe.

Sean stepped up beside him and looked down at the spoor. He would never know how Matatu did it. He had tried to make him explain, but the wizened little gnome had merely laughed with embarrassment and hung his head. It was a kind of magic that went beyond the mere art of observation and deduction. What Matatu had just done was to drop the spoor when it was sweet and hot, and go off at an improbable tangent, running blind through trackless bambOo and over wild peaks, to meet the spoor again with the unerringinstinct of a migrating swallow, having cut the corner and gained threhours on the quarry.

Sean squeezed his shoulder and little Ndorobo wriggled his whole body with pleasure.

They were less than an hour behind the gang now, but the rain and the mist were bringing on the night prematurely. Sean signalled Matatu on. Not one of them had spoken a single word all that day.

The men they were chasing were becoming careless. In the beginning they had anti-tracked and covered spoor, doubled and jinked so cunningly that even Matatu had puzzled to unravel the sign and get away on the run of it - but now they were feeling confident and secure.

Ttry had broken off the succulent bamboo shoots to chew as they march d, leaving glaring wounds on the plants, and they had trodden deeply, heeling with fatigue, leaving sign that Matatu could follow like a tarmac road. One of the fugitives had even defecated on the track, not bothering to cover his faeces, and they were still steaming with his body warmth. Matatu grinned at Sean over his shoulder and made the fluttery hand signal which said 'Very close'.

Sean eased open the action of the double-barrelled Gibbs, without allowing the sidelock to click. He slid the brass-cased cartridges out of the breeches, and replaced them with two Others from the leather ammunition pouch beneath his monkey-skin cape. The .577 cartridges were thicker than a man's thumb and the clumsy, blunt-nosed bullet heads were jacleted in copper and capped with soft blue lead so they could mushroom through living tissue, tearing open a wide channel and inficting terrible damage. This little ritual of changing his cartridges was one of Sean's superstitions - he always did it just before he closed with dangerous game. He closed the rifle as gently and silently as he had opened it and glanced back at the two men behind him.

The whites of Alistair's eyes gleamed in his blackened face. He carried the Bren gun. Sean had not been able to wean him from it.

Despite its unwieldy long barrel and great weight, Alistair loved the automatic weapon. 'When I'm after Mickey Mouse I like to be able to turn the air blue with lead,' he explained with that lazy grin.

'Nobody is going to get a chance to stuff my knockers down my throat, matey!" At the rear Ray Harris gave Sean the thumbs-up signal, but the sweat and rain had cut pale runnels through the soot and fat on his face, and even through the camouflage Sean could see how haggard he was with fear and fatigue. 'The old man is getting past it,' Sean thought dispassionately. 'Have to put him out to grass soon." Ray carried the Stirling sub-machine-gun. Sean suspected it was because he could no longer manage the weight of a more substantial weapon. 'In the bamboo it's point blank." Ray excused his choice, and Sean had not bothered to argue or to point out that the tiny 9 men bullets would be deflected by the frailest twig, and smothered in the dense vegetation of the Aberdares - while the big .600 grain slug from his own Gibbs would plough straight through branch and stem and still blow the guts out of the Mickey Mouse on the other side, while the stubby 20-inch barrels were perfect for close work in the bamboo, and he could swing them without risking hooking up in the brush.

Sean clicked his tongue softly and Matatu went away on the spoor in that soft-footed, ungainly lope which he could keep up day and night without tiring. They crossed another heavily bambooed ridge and in the valley beyond Matatu stopped again. It was so dark by now that Sean had to move up beside him, and go down on one knee to examine the sign.

It took him almost a minute to make sense of it, even after Matatu had pointed out the other set of tracks coming in from the right.

Sean gestured Ray to move up and laid his lips to his ear. 'They have joined another party of Mickey Mice - probably from the base camp.

Eight of them, three women, so we have thirteen in a bunch now. A lovely lucky number." But as he spoke the light was going, and the rain started-again, spilling softly out of the purple-black sky. Within five hundred yards Matatu stopped for the last time and Sean could just make out the pale palm of his right hand as he made the wash-out signal. Night had blanketed the spoor.

The white men each found a treetrunk to prop themselves against, spreading out in a defensive circle facing outwards. Sean took Matatu under the monkey-skin cloak with him as though he were a tired gun dog.

The little man's skinny body was as cold and wet as a trout taken from a mountain stream and he smelled of herbs and leaf mould and wild things. They ate the hard salted dry buffalo meat and cold maize cakes from their belt pouches and slept fitfully in each other's warmth while the raindrops pattered down on the fur over their heads.

Matatu touched Sean's cheek and he was instantly awake in the utter darkness, slipping the safety-catch of the Gibbs that lay across his lap. He sat rigid, listening and alert.

Beside him Matatu snuffled the air and after a moment Sean did the same. 'Woodsmoke?" he whispered, and both of them came to their feet. In the darkness, Sean moved to where Alistair and Ray were lying and got them up. They went forward in the night, holding the belt of the man ahead to keep in contact. The whiffs of smoke were intermittent but stronger.

It took..almost two hours for Matatu to locate the Mau Mau encampmefitprecisely, using his sense of smell and hearing, and at the end the fnt glow of a patch of camp-fire coals. Although the bamboo dripp{d all around, they could hear them - a soft cough, a strangled snore, the gabble of a woman in a nightmare - and Sean and Matatu moved them into position.

It took another hour; but in the utter darkness before the true dawn, Alistair was lying up the slope, forty feet from the dying camp fire. Raymond was amongst the rocks on the bank of the stream on the far side, and Sean lay with Matatu in the dense scrub beside the path that led into the camp.

Sean had the barrel of the Gibbs across his left forearm and his right hand on the pistol grip with the safety-catch under his thumb.

He had spr ,d the fur cloak over both himself and Matatu, but neither of teen even drowsed. They were keyed up to the finest pitch.
