‘It was rather, wasn’t it?’

‘Buy you a beer?’

‘Don’t mind if you do.’

An hour later Colonel Wallace sat at the high table and shuffled his papers. Then he cleared his throat juicily and began: ‘Before I proceed with delivering the judgement, I wish to state that this court was impressed by the bearing and evidence of Sergeant Manyoro. We found him entirely credible, a truthful, loyal and valiant soldier.’ Bobby beamed as he heard his own description repeated faithfully by Wallace. ‘This statement should be appended to Sergeant Manyoro’s service record.’

Wallace swivelled in his seat and glared at Leon. ‘The judgement of this court is as follows. On the charges of cowardice, desertion and dereliction of duty we find the accused not guilty.’ There were murmurs of relief from the defence. Bobby thumped Leon’s knee under cover of the table. Wallace went on sternly, ‘Although the court understood and sympathized with the accused’s instinct to engage the enemy at every opportunity, in the tradition of the British Army, we find that when he took up the pursuit of the rebel war-party in defiance of his orders to proceed with utmost despatch to Niombi station he transgressed the Articles of War, which require strict obedience to the orders of a superior officer. We therefore have no alternative but to find him guilty of disobeying the written orders of his superior officer.’

Bobby and Leon stared at him with dismay and Snell folded his arms across his chest. He leaned back in his chair with a smirk on his wide mouth.

‘I come now to the sentence. The accused will stand.’ Leon came to his feet and snapped to rigid attention, staring at the wall behind Wallace’s head. ‘The verdict of guilty will be recorded in the service record of the accused. He will be detained until this court rises and immediately thereafter will be returned to duty with the full responsibility and privileges of his rank. God save the King!

‘These proceedings are at an end.’ Wallace stood, bowed to the men below him and led his fellow judges to the bar. ‘There’s time for a peg before the train leaves. I’ll have a whisky. What about you chaps?’

As Leon and Bobby headed for the door of the courtroom, which had now reverted to its former role as the officers’ mess, they drew level with the table at which Snell was still seated. He stood up and replaced his cap on his head, forcing them to come to attention and salute. His pale blue eyes bulged from their sockets and his lips were set in an expression that gave him the appearance not so much of a frog but of a venomous toad. After a deliberate pause he returned their salutes. ‘I will have fresh orders for you tomorrow morning, Courtney. Be at my office at eight hundred hours sharp. In the meantime you may carry on,’ he snapped.

‘I doubt very much that you’ve made Froggy your friend for life,’ Bobby muttered, as they went out on to the sunlit parade-ground. ‘He’ll make your life extremely interesting from now onwards. My guess is that his new orders will take you on foot patrol to Lake Natron or some other remote and God-forsaken place. We won’t be seeing much of you for a month or so, but at least you’ll be seeing more of the country.’

His askari thronged around Leon to congratulate him. ‘Jambo, Bwana. Welcome back.’

‘At least you have some friends left,’ Bobby consoled him. ‘May I use the jalopy while you’re sojourning in the outer wilderness?’

Many months later two horsemen rode stirrup to stirrup along the bank of the Athi river. The grooms followed at a distance, leading the spare horses. The riders wore wide-brimmed slouch hats and carried their lances at rest. Before them, the wide green expanse of the Athi plains stretched to the horizon. It was dotted with herds of zebra, ostriches, impala and wildebeest. A pair of giraffe stared down at them with great dark eyes as they rode past at a distance of only a hundred paces.

‘Sir, I can’t stand it much longer,’ Leon told his favourite uncle. ‘I’ll have to put in for a transfer to another regiment.’

‘I doubt any would have you, my boy. You have a large black mark on your service record,’ said Colonel Penrod Ballantyne, commanding officer of the 1st Regiment, The King’s African Rifles. ‘What about India? I might put in a word for you with a few friends who were in South Africa with me.’ Penrod was testing him.

‘Thank you, sir, but I would never dream of leaving Africa,’ Leon replied. ‘When you were weaned on Nile water you can never break the shackles.’

Penrod nodded. It was the reply he had expected. He took a silver case from his top pocket and tapped out a Player’s Gold Leaf. He put it between his lips and offered one to Leon.

‘Thank you, sir, but I don’t indulge.’ Leon read the engraving on the inside of the lid before his uncle closed it. ‘To Twopence, happy 50th birthday from your adoring wife, Saffron.’ Aunt Saffron had a quirky sense of humour. Her nickname for Penrod had originally been Penny but after all their years of marriage she had decided his value had doubled.

‘Well, sir, if no one else will have me I suppose I’ll just have to put in my papers and resign my commission – I’ve already wasted nearly three years wandering in small circles in the wilderness, getting nowhere, at the behest of Major Snell. I can’t take any more.’

Penrod considered this, but before he could decide on a suitable reply a movement further down the riverbank caught his eye. A warthog boar trotted out of a dense clump of riverine scrub. His curved white tusks almost met above his comically hideous face, which was decorated with the black wart-like protuberances that gave him his name. He carried his tufted tail straight as a ruler, pointing up at the sky. ‘Here we go!’ Penrod shouted. ‘Tally ho and away!’ He kicked his heels into his mare’s flanks and she was off.

Leon raced after him, leaning along the neck of his polo pony as he couched his long pig spear. ‘By God, this one’s a huge brute. Look at those tusks! Up and at him, Uncle!’

Penrod’s mare ran lightly, closing swiftly on the quarry, but Leon’s bay gelding pushed up half a length behind her streaming tail. The warthog heard their hoofs thundering, stopped and looked back. He stared at the charging horses with astonishment, then whipped around and darted away across the plain kicking up puffs of dust with each beat of his sharp little hoofs, but he could not outrun the mare.

Penrod leaned out of the saddle and lined up the point of his spear, aiming at the patch of bald grey skin between the animal’s humped shoulder-blades.

‘Stick him, Twopence!’ In his excitement Leon called the name reserved for exclusive use by his aunt. Penrod showed no sign of having heard. He carried home his charge, the point of his spear arrowing in towards the boar’s withers. But at the last instant the warthog changed direction and doubled back under the mare’s front legs. Even she, bred and trained to follow a bouncing polo ball adroitly, could not counter the manoeuvre and overran the quarry. The spear head glanced off the boar’s tough hide without drawing blood, and Penrod pulled the mare’s head around steeply. She pranced and mouthed the bit, her eyes wild with the excitement of the chase.

‘Come away, my darling! Full tilt and hell for leather!’ Penrod exhorted her, and touched her ribs with blunted rowels. She came around again for the next run, but Leon cut across her line and his pony fastened on the warthog’s hindquarters as though he was attached to it by a leash. Horse and rider stayed with the pig as it twisted, turned and doubled desperately. They went around in a circle, Penrod laughing and shouting advice after them.

‘Stay with him, sir. Watch out for the tusks – he nearly had you there!’ The boar broke back on Leon’s blind side and almost reached the cover of the dense scrub from which he had appeared, but Leon, rising high in his stirrups, switched his spear neatly to his left hand and drove the point between the warthog’s shoulders. The animal took it cleanly through the heart. Leon let the shaft drop back as the gelding passed over the dying beast and the spearhead came free without jarring his wrist. The bright steel and two feet of the shaft behind it shone with the boar’s heart blood. It squealed once and its front legs folded under it. It dropped, slid on its snout, then flopped on to its side, gave three kicks with its back legs and was dead.
