“Maybe,” admitted Mackenzie; “it may be Jones. But I wouldn’t like to accuse him till I was sure: that would be foolishness.”

“Well, don’t notice it, then,” said Susan, pleased with Mackenzie’s prudence. “I don’t care what anybody say about me, so long as me conscience don’t trouble me an’ it don’t put you out. But I wouldn’t like anybody else do me a thing like this again, for my character is all dat I have, and what one person do another may do.”

But as Mackenzie preferred always to deal with facts and not with possibilities, he let the subject drop, and by the time he returned to his work that afternoon he had ceased to think about the letter.

Not for an instant, however, did Susan cease to think of it. She was desperately frightened. As she had said to Mackenzie, what one person had done another might do, and then Mackenzie would begin to grow suspicious. She feared to meet Samuel again, yet she wanted to see him at least once more: she wanted to warn him. How could she see him? . . . If she risked a meeting some enemy of hers might learn about it, and this time she might not be able to find a ready excuse. It is true that Mackenzie had told her she should be polite to Jones if she should see him, but at that time no anonymous letter had coupled her name with that of her former lover. And to meet Jones the very next time she went to Colon would of a surety have a suspicious look.

Should she write to him? Letters went astray sometimes, and Samuel was careless.

Then what was she to do?

She worried herself all that afternoon, trying to think a way out of the difficulty. Suppose Mackenzie should meet Jones and mention the letter to him? Jones might say something about his meeting her at her people’s house . . . and then!

She felt sick of the difficult position in which she found herself, wearied to death; she had a sensation of being tied hand and foot, of being a prisoner; she longed for release, and she knew that only one avenue of escape was open to her. She could leave Culebra, leave Panama, and go back to Jamaica with Jones. She would be happier there, free, more like what she used to be before her marriage. What did the hardships and discontents of that time now seem to her? They were as nothing; she remembered only that she had been happier, and what was the good of marriage if it brought but boredom and disgust? But there was the divorce court to think of also, and her terrible fall from respectability. Even if Mackenzie did not take the trouble to divorce her, she would be a byword amongst those persons who should know her as a woman who had left her husband for another man. She could not face that shame.

She decided that she must wait. Nothing might happen in the next couple of weeks. At the end of that time it would not seem at all strange if she went to Colon to see her people; then, if she met Samuel, she would tell him of the letter and put him on his guard.

She felt grateful to Mackenzie for his confidence in her. Such confidence displayed by a man like Tom would merely have awakened her contempt; but she saw that her husband was perfectly sincere, and determined to take her part against her traducers. Had he doubted her he would have shown it at once, he would have made inquiries, and the sequel would have been terrible. That, she argued, would have been unjust to her. She had done nothing deserving of blame. She had met Jones twice; she had not told her husband the truth about those meetings; but on the other hand she had refused to fly with Samuel, and on that demonstration of virtuous feeling she greatly preened herself. She had behaved splendidly; after such conduct it would have been most unjust if Mackenzie had acted any differently from how he had acted. And to think that it was Tom who had tried to injure her; to think too that nothing painful could be done to him! She thirsted for revenge, yet she knew that Tom must escape scot-free. The slightest attempt at reprisals might but lead to exposure. The thought that she could not pay back Tom with heavy interest was like wormwood to her soul.
