george allerton had changed since he left england. the flesh had fallen away from his bones, and his face was sallow. he had not stood the climate well. his expression had changed too, for there was a singular querulousness about his mouth, and his eyes were shifty and cunning. he had lost his good looks.

'can i come in?' he said.

'yes,' answered alec, and then turning to the doctor: 'you might stay a moment, will you?'

'certainly.'

adamson stood where he was, with his back to the flap that closed the tent. alec looked up quickly.

'didn't selim tell you i wanted to speak to you?'

'that's why i've come,' answered george.

'you've taken your time about it.'

'i say, could you give me a drink of brandy? i'm awfully done up.'

'there's no brandy left,' answered alec.

'hasn't the doctor got some?'

'no.'

there was a long pause. adamson and walker did not know what was the matter; but they saw that there was something serious. they had never seen alec so cold, and the doctor, who knew him well, saw that he was very angry. alec lifted his eyes again and looked at george slowly.

'do you know anything about the death of that turkana woman?' he asked abruptly.

george did not answer immediately.

'no. how should i?' he said presently.

'come now, you must know something about it. last tuesday you came into camp and said the turkana were very much excited.'

'oh, yes, i remember,' answered george, unwillingly

'well?'

'i'm not very clear about it. the woman had been shot, hadn't she? one of the station boys had been playing the fool with her, and he seems to have shot her.'

'have you made no attempt to find out which of the station boys it was?'

'i haven't had time,' said george, in a surly way. 'we've all been worked off our legs during the last three days.'

'do you suspect no one?'

'i don't think so.'

'think a moment.'

'the only man who might have done it is that big scoundrel we got on the coast, the swahili beggar with one ear.'

'what makes you think that?'

'he's been making an awful nuisance of himself, and i know he's been running after the women.'

alec did not take his eyes off george. walker saw what was coming and looked down at the ground.

'you'll be surprised to hear that when the woman was found she wasn't dead.'

george did not move, but his cheeks became if possible more haggard. he was horribly frightened.

'she didn't die for nearly an hour.'

there was a very short silence. it seemed to george that they must hear the furious beating of his heart.

'was she able to say anything?'

'she said you'd shot her,'

'what a damned lie!'

'it appears that you were—playing the fool with her. i don't know why you quarrelled. you took out your revolver and fired point blank.'

george laughed.

'it's just like these beastly niggers to tell a stupid lie like that. you wouldn't believe them rather than me, would you? after all, my word's worth more than theirs.'

alec quietly took from his pocket the case of an exploded cartridge. it could only have fitted a revolver.

'this was found about two yards from the body and was brought to me this evening.'

'i don't know what that proves.'

'you know just as well as i do that none of the natives has a revolver. beside ourselves only one or two of the servants have them.'

george took his handkerchief from his pocket and wiped his face. his throat was horribly dry, and he could hardly breathe.

'will you give me your revolver,' said alec, quietly.

'i haven't got it. i lost it this afternoon when we made that sortie. i didn't tell you as i thought you'd get in a wax about it.'

'i saw you cleaning it less than an hour ago,' said alec, gravely.

george shrugged his shoulders pettishly.

'perhaps it's in my tent. i'll go and see.'

'stop here,' said alec sharply.

'look here, i'm not going to be ordered about like a dog. you've got no right to talk to me like that. i came out here of my own free will, and i won't let you treat me like a damned nigger.'

'if you put your hand to your hip-pocket i think you'll find your revolver there.'

'i'm not going to give it you,' said george, his lips white with fear.

'do you want me to come and take if from you myself?'

the two men stared at one another for a moment. then george slowly put his hand to his pocket and took out the revolver. but a sudden impulse seized him. he raised it, quickly aimed at alec, and fired. walker was standing near him, and seeing the movement, instinctively beat up the boy's hand as pulled the trigger. in a moment the doctor had sprung forward and seizing him round the waist, thrown him backwards. the revolver fell from his hand. alec had not moved.

'let me go, damn you!' cried george, his voice shrill with rage.

'you need not hold him,' said alec.

it was second nature with them all to perform alec's commands, and without thinking twice they dropped their hands. george sank cowering into a chair. walker, bending down, picked up the revolver and gave it to alec, who silently fitted into an empty chamber the cartridge that had been brought to him.

'you see that it fits,' he said. 'hadn't you better make a clean breast of it?'

george was utterly cowed. a sob broke from him.

'yes, i shot her,' he said brokenly. 'she made a row and the devil got into me. i didn't know what i'd done till she screamed and i saw the blood.'

he cursed himself for being such a fool as to throw the cartridge away. his first thought had been to have all the chambers filled.

'do you remember that two months ago i hanged a man to the nearest tree because he'd murdered one of the natives?'

george sprang up in terror, and he began to tremble.

'you wouldn't do that to me.'

a wild prayer went up in his heart that mercy might be shown him, and then bitter anger seized him because he had ever come out to that country.

'you need not be afraid,' answered alec coldly. 'in any case i must preserve the native respect for the white man.'

'i was half drunk when i saw the woman. i wasn't responsible for my actions.'

'in any case the result is that the whole tribe has turned against us.'

the chief was alec's friend, and it was he who had sent him the exploded cartridge. the news came to alec like a thunderclap, for the turkana were the best part of his fighting force, and he had always placed the utmost reliance on their fidelity. the chief said that he could not hold in his young men, and not only must alec cease to count upon them, but they would probably insist on attacking him openly. they had stirred up the neighbouring tribes against him and entered into communication with the arabs. he had been just at the turning point and on the verge of a great success, but now all that had been done during three years was frustrated. the arabs had seized the opportunity and suddenly assumed the offensive. the unexpectedness of their attack had nearly proved fatal to alec's party, and since then they had all had to fight for bare life.

george watched alec as he stared at the ground.

'i suppose the whole damned thing's my fault,' he muttered.

alec did not answer directly.

'i think we may take it for certain that the natives will go over to the slavers to-morrow, and then we shall be attacked on all sides. we can't hold out against god knows how many thousands. i've sent rogers and deacon to bring in all the latukas, but heaven knows if they can arrive in time.'

'and if they don't?'

alec shrugged his shoulders, but did not speak. george's breathing came hurriedly, and a sob rose to his throat.

'what are you going to do to me, alec?'

mackenzie walked up and down, thinking of the gravity of their position. in a moment he stopped and looked at walker.

'i daresay you have some preparations to make,' he said.

walker got up.

'i'll be off,' he answered, with a slight smile.

he was glad to go, for it made him ashamed to watch the boy's humiliation. his own nature was so honest, his loyalty so unbending, that the sight of viciousness affected him with a physical repulsion, and he turned away from it as he would have done from the sight of some hideous ulcer. the doctor surmised that his presence too was undesired. murmuring that he had no time to lose if he wanted to get his patients ready for a night march, he followed walker out of the tent. george breathed more freely when he was alone with alec.

'i'm sorry i did that silly thing just now,' he said. 'i'm glad i didn't hit you.'

'it doesn't matter at all,' smiled alec. 'i'd forgotten all about it.'

'i lost my head. i didn't know what i was doing.'

'you need not trouble about that. in africa even the strongest of us are apt to lose our balance.'

alec filled his pipe again, and lighting it, blew heavy clouds of smoke into the damp air. his voice was softer when he spoke.

'did you ever know that before we came away i asked lucy to marry me?'

george did not answer. he stifled a sob, for the recollection of lucy, the centre of his love and the mainspring of all that was decent in him, transfixed his heart with pain.

'she asked me to bring you here in the hope that you'd,'—alec had some difficulty in expressing himself—'do something that would make people forget what happened to your father. she's very proud of her family. she feels that your good name is—besmirched, and she wanted you to give it a new lustre. i think that is the object she has most at heart in the world. it is as great as her love for you. the plan hasn't been much of a success, has it?'

'she ought to have known that i wasn't suited for this sort of life,' answered george, bitterly.

'i saw very soon that you were weak and irresolute, but i thought i could put some backbone into you. i hoped for her sake to make something of you after all. your intentions seemed good enough, but you never had the strength to carry them out.' alec had been watching the smoke that rose from his pipe, but now he looked at george. 'i'm sorry if i seem to be preaching at you.'

'oh, do you think i care what anyone says to me now?'

alec went on very gravely, but not unkindly.

'then i found you were drinking. i told you that no man could stand liquor in this country, and you gave me your word of honour that you wouldn't touch it again.'

'yes, i broke it. i couldn't help myself. the temptation was too strong.'

'when we came to the station at munias, and i was laid up with fever, you and macinnery took the opportunity to get into an ugly scrape with some native women. you knew that that was the one thing i would not stand. i have nothing to do with morality—everyone is free in these things to do as he chooses—but i do know that nothing causes more trouble with the natives, and i've made definite rules on the subject. if the culprits are swahilis i flog them, and if they're whites i send them back to the coast. that's what i ought to have done with you, but it would have broken lucy's heart.'

'it was macinnery's fault.'

'it's because i thought macinnery was chiefly to blame that i sent him back alone. i determined to give you another chance. it struck me that the feeling of authority might have some influence on you, and so, when i had to build a boma to guard the road down to the coast, i put the chief part of the stores in your care and left you in command. i need not remind you what happened there.'

george looked down at the floor sulkily, and in default of excuses, kept silent. he felt a sullen resentment as he remembered alec's anger. he had never seen him give way before or since to such a furious wrath, and he had seen alec hold himself with all his strength so that he might not thrash him. alec remembered too, and his voice once more grew hard and cold.

'i came to the conclusion that it was hopeless. you seemed to me rotten through and through.'

'like my father before me,' sneered george, with a little laugh.

'i couldn't believe a word you said. you were idle and selfish. above all you were loathsomely, wantonly cruel. i was aghast when i heard of the fiendish cruelty with which you'd used the wretched men whom i left with you. if i hadn't returned in the nick of time, they'd have killed you and looted all the stores.'

'it would have upset you to lose the stores, wouldn't it?'

'is that all you've got to say?'

'you always believed their stories rather than mine.'

'it was difficult not to believe when a man showed me his back all torn and bleeding, and said you'd had him flogged because he didn't cook your food to your satisfaction.'

'i did it in a moment of temper. a man's not responsible for what he does when he's got fever.'

'it was too late to send you to the coast then, and i was obliged to take you on. and now the end has come. your murder of that woman has put us all in deadly peril. already to your charge lie the deaths of richardson and thompson and about twenty natives. we're as near destruction as we can possibly be; and if we're killed, to-morrow the one tribe that has remained friendly will be attacked and their villages burnt. men, women and children, will be put to the sword or sold into slavery.'

george seemed at last to see the abyss into which he was plunged, and his resentment gave way to despair.

'what are you going to do?'

'we're far away from the coast, and i must take the law into my own hands.'

'you're not going to kill me?' gasped george.

'no,' said alec scornfully.

alec sat on the little camp table so that he might be quite near george.

'are you fond of lucy?' he asked gently.

george broke into a sob.

'o god, you know i am,' he cried piteously. 'why do you remind me of her? i've made a rotten mess of everything, and i'm better out of the way. but think of the disgrace of it. it'll kill lucy. and she was hoping i'd do so much.'

he hid his face in his hands and sobbed broken-heartedly. alec, strangely touched, put his hand on his shoulder.

'listen to me,' he said. 'i've sent deacon and rogers to bring up as many latukas as they can. if we can tide over to-morrow we may be able to inflict a crushing blow on the arabs; but we must seize the ford over the river. the arabs are holding it and our only chance is to make a sudden attack on them to-night before the natives join them. we shall be enormously outnumbered, but we may do some damage if we take them by surprise, and if we can capture the ford, rogers and deacon will be able to get across to us. we've lost richardson and thompson. perkins is down with fever. that reduces the whites to walker, and the doctor, condamine, mason, you and myself. i can trust the swahilis, but they're the only natives i can trust. now, i'm going to start marching straight for the ford. the arabs will come out of their stockade in order to cut us off. in the darkness i mean to slip away with the rest of the white men and the swahilis, i've found a short cut by which i can take them in the rear. they'll attack just as the ford is reached, and i shall fall upon them. do you see?'

george nodded, but he did not understand at what alec was driving. the words reached his ears vaguely, as though they came from a long way off.

'i want one white man to lead the turkana, and that man will run the greatest possible danger. i'd go myself only the swahilis won't fight unless i lead them.... will you take that post?'

the blood rushed to george's head, and he felt his ears singing.

'i?'

'i could order you to go, but the job's too dangerous for me to force it on anyone. if you refuse i shall call the others together and ask someone to volunteer.'

george did not answer.

'i won't hide from you that it means almost certain death. but there's no other way of saving ourselves. on the other hand, if you show perfect courage at the moment the arabs attack and the turkana find we've given them the slip, you may escape. if you do, i promise you that nothing shall be said of all that has happened here.'

george sprang to his feet, and once more on his lips flashed the old, frank smile.

'all right! i'll do that. and i thank you with all my heart for giving me the chance.'

alec held out his hand, and he gave a sigh of relief.

'i'm glad you've accepted. whatever happens you'll have done one brave action in your life.'

george flushed. he wanted to speak, but hesitated.

'i should like to ask you a great favour,' he said at last.

alec waited for him to go on.

'you won't let lucy know the mess i've made of things, will you? let her think i've done all she wanted me to do.'

'very well,' answered alec gently.

'will you give me your word of honour that if i'm killed you won't say anything that will lead anyone to suspect how i came by my death.'

alec looked at him silently. it flashed across his mind that it might be necessary under certain circumstances to tell the whole truth. george was greatly moved. he seemed to divine the reason of alec's hesitation.

'i have no right to ask anything of you. already you've done far more for me than i deserved. but it's for lucy's sake that i implore you not to give me away.'

alec, standing entirely still, uttered the words slowly.

'i give you my word of honour that whatever happens and in whatever circumstances i find myself placed, not a word shall escape me that could lead lucy to suppose that you hadn't been always and in every way upright, brave, and honourable. i will take all the responsibility of your present action.'

'i'm awfully grateful to you.'

alec moved at last. the strain of their conversation was become almost intolerable. alec's voice became cheerful and brisk.

'i think there's nothing more to be said. you must be ready to start in half an hour. here's your revolver.' there was a twinkle in his eyes as he continued: 'remember that you've discharged one chamber. you'd better put in another cartridge.'

'yes, i'll do that.'

george nodded and went out. alec's face at once lost the lightness which it had assumed a moment before. he knew that he had just done something which might separate him from lucy for ever. his love for her was now the only thing in the world to him, and he had jeopardised it for that worthless boy. he saw that all sorts of interpretations might be put upon his action, and he should have been free to speak the truth. but even if george had not exacted from him the promise of silence, he could never have spoken a word. he loved lucy far too deeply to cause her such bitter pain. whatever happened, she must think that george was a brave man, and had died in the performance of his duty. he knew her well enough to be sure that if death were dreadful, it was more tolerable than dishonour. he knew how keenly she had felt her disgrace, how it affected her like a personal uncleanness, and he knew that she had placed all her hopes in george. her brother was rotten to the core, as rotten as her father. how could he tell her that? he was willing to make any sacrifice rather than allow her to have such knowledge. but if ever she knew that he had sent george to his death she would hate him. and if he lost her love he lost everything. he had thought of that before he answered: lucy could do without love better than without self-respect.

but he had told george that if he had pluck he might get through. would he show that last virtue of a blackguard—courage?
