Next morning the _Times_ contained an advertisement offering twenty guineas for a prayer-book lost in Hanover Square, and valuable, not in itself, but as a relic of a deceased parent.

In the afternoon Arthur called to know if anybody had brought the prayer-book back.

Helen shook her head sadly, and said, "No."

He seemed very sorry and so penitent, that Helen said:

"Do not despair. And if it is gone, why, I must remember you have forgiven me something, and I must forgive you."

"If you please, miss, here is a woman wishes to speak to you; says she has brought a prayer-book."

"Oh, show her up at once," cried Helen.

Arthur turned away his head to hide a cynical smile. He had good reasons for thinking it was not the one he had flung out of the window yesterday.
