'You see, the fault was his. He had committed a grave error. It was not unjust that he should suffer for the catastrophe that he had brought about.'

'At those times one doesn't think of justice. He was so young, so frank and honest. Wouldn't it have been nobler to give your life for his?'

'Oh, my dear,' he answered, with all the gentleness that was in him, 'you don't know how easy it is to give one's life, how much more difficult it is to be just than generous. How little you know me! Do you think I should have hesitated if the difficulty had been one that my death could solve? It was necessary that I should live. I had my work to do. I was bound by solemn treaties to the surrounding tribes. Even if that had been all, it would have been cowardly for me to die.'

'It is easy to find excuses for not acting like a brave man.' She flung the words at him with indignant scorn.

'I was indispensable,' he answered. 'The whites I took with me I chose as instruments, not as leaders. If I had died the expedition would have broken in pieces. It was my influence that held together such of the native tribes as remained faithful to us. I had given my word that I would not desert them till I had exterminated the slave-raiders. Two days after my death my force would have melted away, and the whites would have been helpless. Not one of them would have escaped. And then the country would have been given up, defenceless, to those cursed Arabs. Fire and sword would have come instead of the peace I promised; and the whole country would have been rendered desolate. I tell you that it was my duty to live till I had carried out my work.'

Lucy drew herself up a little. She looked at him firmly, and said very quietly and steadily:

'You coward! You coward!'

'I knew at the time that what I did might cost me your love, and though you won't believe this, I did it for your sake.'

'I wish I had a whip in my hand that I might slash you across the face.'

For a moment he did not say anything. She was quivering with indignation and with contempt.
