'Someone downstairs asked me to give it you,' she whispered. 'You needn't blush, you know.'

Lydia was too surprised to manifest any such self-consciousness. She murmured thanks, and looked at the address. It was a man's writing, but she had no idea whose. She opened the envelope and found Ackroyd's short note.

What did this mean? It at once flashed across Lydia's mind that there might be some connection between this and Thyrza's strange disorder. Old habit still brought Ackroyd and Thyrza together in her thoughts. Yet how was it possible? Ackroyd was engaged to Totty Nancarrow, and Thyrza had never shown the least interest when she mentioned him of late. Was he going to make trouble, now at the last moment, when everything seemed to have taken the final form?

Since Thyrza's engagement to Gilbert, there was no longer need of subtle self-deceptions, but, though she might now freely think of him, Lydia soon found that Ackroyd was not the same in her eyes. The first rumours of his abandonment to vulgar dissipation she utterly refused to credit, but before long she had to believe them in spite of herself. She saw him one night coming out of a public-house, singing a drunken song. It was a terrible blow to her; she had to question herself much, and to make great efforts to understand a man's nature. She had thought him incapable of such things. The vague stories of earlier wildness she had held no account of. When a woman says 'Oh, that is past,' she means 'It does not exist, and never did exist.'

It surprised her that she still thought of him with heartache. Her quarrel with Mary Bower seemed an encouragement to the love she kept so secret. She found a thousand excuses for him; she pitied him deeply; she longed to go and speak to him. Why could she not do so? Often and often she rehearsed conversations with him, in which she told him how unworthy it was to fall so, and implored him for his own sake to be a man again. She might have realised such a dialogue—though it would have cost her much—but for the news that he had begun to pay attention to Totty Nancarrow.

Then she knew jealousy. Of Thyrza she could not be jealous, but to imagine him giving his affection to a girl like Totty Nancarrow made her rebellious and scornful. How little could any of her work-room companions know what was passing in Lydia's breast when she had one of her days of quietness and bent with such persistence over her sewing! If spoken to, she raised the same kind, helpful face as ever; you could not imagine that a minute ago a tear had all but come to her eyes, that in thought she had been uttering words of indignant passion. They were rare, those days in which she could not be quite herself. It was not her nature to yield when weakness tempted.

And now he had written to her. Having read the note, she put it into the bosom of her dress, and, whilst her fingers were busy, she turned over every possible explanation in her mind. She knew that he had abandoned his evil habits of late, and she could be just enough not to refuse Totty some credit for the change. Gilbert himself had said that the girl's influence seemed on the whole good. But some mystery was now going to reveal itself. It concerned Thyrza; she was sure it did. The fact that the note was delivered in this way, and the request for secrecy which it contained, made this certain.

At dinner-time, and again in the evening, Thyrza was still in the same state of depression and feverishness. Lydia said nothing of the business which would take her out at eight o'clock. When the time came, and she had to make an excuse, Thyrza said that she too would go out; she wanted to see Totty.

'You'll tell Gilbert?' Lydia replied, afraid to make any opposition herself.

'No. He'd say it wasn't good for me to go out, and I want to go. You won't say anything, Lyddy?'
