Thanks to a sovereign judiciously bestowed on the caretaker, I had discovered that Rose Gernon intended to visit Felix at eight o'clock. How the caretaker found out I do not know, but in some mysterious way servants seem to gain all information concerning the doings of their superiors. It sufficed for me that Rose would be in the rooms of Felix on this evening, and that Olivia would catch them in a trap. I had no pity for the guilty pair, but I was genuinely sorry for Olivia. She little knew the torture she was about to undergo. I did, and almost regretted that I had interfered in the matter. However, I consoled myself with the reflection that it was better for her to suffer a few hours' pain than lifelong misery. That she agreed to go to Jermyn Street at that hour without a chaperon proved how desirous she was of learning the truth. Delicately nurtured, gently bred, she must have felt horrified at the risk she was running of losing her good name, but, seeing that her life's happiness depended upon knowing all, she flung etiquette to the winds and came. When I found her at the foot of the stairs at eight o'clock, I admired and respected her from the bottom of my heart. "Am I late?" she asked, touching my hand with trembling fingers. "Only five minutes," said I, looking at my watch. "I have been waiting at the head of the stairs for that time. However, we can soon walk round to Jermyn Street." "Do you think anyone will know me, Mr. Denham?" said Olivia, taking my arm. "See, I have on a plain dress, and this veil is a thick one." "No one will recognize you," I answered soothingly; "nor do I think you will meet any one of your acquaintances." "I should have brought my mother, but that I wished her to know nothing of this treachery. If I find I have been deceived, I shall break off my engagement with Francis. But you will keep silent about my visit, will you not, Mr. Denham?" "No one shall hear a word from me," I answered earnestly. "But keep up your spirits, Miss Bellin. Even if you find you have been deceived, there will be some consolation in knowing that it is Felix, and not Francis." "You are wrong there," she replied positively; "it is Francis. I have told you so all along." I shrugged my shoulders without reply. Evidently nothing could shake her faith in the man. All I could hope for was that the two confederates would betray themselves. "What are you going to do, Mr. Denham?" asked Olivia anxiously. "We will go up to the rooms of Briarfield," I answered, "and there overhear their conversation." "Is that not dishonorable?" she said, shrinking back. "In most cases it would be," I replied hastily, "but it does not do to be too particular in this matter. If you break in on them, they may deny everything. Thinking they are alone, you will hear the truth. Remember, Miss Bellin, when one deals with a villain, one must beat him with his own weapons. Depend upon it, it is most necessary that we should learn all."
