"Nothing!" answered Kate Daltrey, coldly. "Her only chance is concealment, and what a poor chance that is! I went over to Sark, never thinking that your Miss Ollivier whom I had heard so much of was Olivia Foster. It is an out-of-the-world place; but so much the more readily they will find her, if they once get a clew. A fox is soon caught when it cannot double; and how could Olivia escape if they only traced her to Sark?" My dread of the woman into whose hands my imbecile curiosity had put the clew was growing greater every minute. It seemed as if Olivia could not be safe now, day or night; yet what protection could I or Tardif give to her? "You will not betray her?" I said to Kate Daltrey, though feeling all the time that I could not trust her in the smallest degree. "I have promised dear Julia that," she answered. I should fail to give you any clear idea of my state of mind should I attempt to analyze it. The most bitter thought in it was that my own imprudence had betrayed Olivia. But for me she might have remained for years, in peace and perfect seclusion, in the home to which she had drifted. Richard Foster and his accomplice must have lost all hope of finding her during the many months that had elapsed between her disappearance and my visit to their solicitors. That had put them on the track again. If the law forced her back to her husband, it was I who had helped him to find her. That was a maddening thought. My love for her was hopeless; but what then? I discovered to my own amazement that I had loved her for her sake, not my own. I had loved the woman in herself, not the woman as my wife. She could never become that, but she was dearer to me than ever. She was as far removed from me as from Tardif. Could I not serve her with as deep a devotion and as true a chivalry as his? She belonged to both of us by as unselfish and noble a bond as ever knights of old were pledged to. It became my duty to keep a strict watch over the woman who had come to Guernsey to find Olivia. If possible I must decoy her away from the lowly nest where my helpless bird was sheltered. She had not sent for me again, but I called upon her the next morning professionally, and stayed some time talking with her. But nothing resulted from the visit beyond the assurance that she had not yet made any progress toward the discovery of my secret. I almost marvelled at this, so universal had been the gossip about my visits to Sark in connection with the breaking-off of my engagement to Julia. But that had occurred in the spring, and the nine-days' wonder had ceased before my patient came to the island. Still, any accidental conversation might give her the information, and open up a favorable chance for her. I must not let her go across to Sark unknown to myself.
