'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.
