She signed and inclosed the letter, and wrote the address. Then, for the first time, an obstacle which she ought to have seen before showed itself, standing straight in her way.

There was no time to forward her letter in the ordinary manner by post. It must be taken to its destination by a private messenger. Lady Janet’s servants had hitherto been, one and all, at her disposal. Could she presume to employ them on her own affairs, when she might be dismissed from the house, a disgraced woman, in half an hour’s time? Of the two alternatives it seemed better to take her chance, and present herself at the Refuge without asking leave first.

While she was still considering the question she was startled by a knock at her door. On opening it she admitted Lady Janet’s maid, with a morsel of folded note-paper in her hand.

“From my lady, miss,” said the woman, giving her the note. “There is no answer.”

Mercy stopped her as she was about to leave the room. The appearance of the maid suggested an inquiry to her. She asked if any of the servants were likely to be going into town that afternoon.

“Yes, miss. One of the grooms is going on horseback, with a message to her ladyship’s coach-maker.”

The Refuge was close by the coach-maker’s place of business. Under the circumstances, Mercy was emboldened to make use of the man. It was a pardonable liberty to employ his services now.

“Will you kindly give the groom that letter for me?” she said. “It will not take him out of his way. He has only to deliver it—nothing more.”

The woman willingly complied with the request. Left once more by herself, Mercy looked at the little note which had been placed in her hands.

It was the first time that her benefactress had employed this formal method of communicating with her when they were both in the house. What did such a departure from established habits mean? Had she received her notice of dismissal? Had Lady Janet’s quick intelligence found its way already to a suspicion of the truth? Mercy’s nerves were unstrung. She trembled pitiably as she opened the folded note.
