"The first door on the right is the sitting-room, senor," he said, respectfully, and I went to it and knocked. Getting no reply, I knocked again loudly; and again failing to get any response, my fears, that after all something was wrong, began to revive. I knocked a third time, and still getting no answer tried to open the door, and found it locked on the inside. I called Sarita, loudly, by name then, knowing my voice would re-assure her, and when no response came, I tried the other doors and found them locked like the first, on the inside.

I called up Rubio then.

"Does the senorita generally lock her doors?" I asked Carlos.

"I have never known her to do it before, senor."

"Something is wrong; we must break our way in;" and I sent Carlos down at once for tools.

"What can it mean?" he said, in a tone of dismay; and as soon as the tools were brought he set about forcing an entrance.

"Did you see the senorita after Colonel Livenza left?" I asked the man.

"My wife did, senor. She said she was tired, and complained of a headache, and that she would go to bed early, and asked us to keep the house quiet and not disturb her."

"She has gone," I exclaimed, as the meaning of it all rushed upon me. "He brought with him the means for her to escape, and under some pretext induced her to fly, after she had lulled the suspicions of these two with this plea."

And so it proved. The rooms were empty; and an open window, from which hung a knotted rope fastened to a bedstead, told us plainly enough how the escape had been made. For a moment my heart sank with dismay at the sight; but I rallied under pressure of the need for instant action.
