A Coin of Edward VII by Fergus Hume — Read

The discovery of the coin perplexed Giles. It was certainly the trinket attached to the bangle which he had given Anne. And here he found it in the grounds of the Priory. This would argue that she was in the neighborhood, in the house it might be. She had never been to the Priory when living at The Elms, certainly not after the New Year, when she first became possessed of the coin. He decided, therefore, that at some late period -- within the last few days -- she had been in the park, and there had lost the coin. It would, indeed, be strange if this trifling present which he had made her should be the means of tracing her to her hiding-place.

And that hiding-place was the Priory. Giles felt sure of this. If she was in the neighborhood and walking about openly, she would be discovered and arrested. Therefore she must be concealed in the house. She had gone off with Walter Franklin, and here she was under the wing of his brother George. The case grew more mysterious and perplexing as time went on. Giles did not know which way to turn, or what advantage to reap from this discovery.
