That was the happiest evening of my life; nor ever do I expect to experience its like; but at last, as is the way of happiness, it terminated. We descended to the compound, and I walked with Lys to the door of her quarters. There again she kissed me and bade me good night, and then she went in and closed the door. I went to my own room, and there I sat by the light of one of the crude candles we had made from the tallow of the beasts we had killed, and lived over the events of the evening. At last I turned in and fell asleep, dreaming happy dreams and planning for the future, for even in savage Caspak I was bound to make my girl safe and happy. It was daylight when I awoke. Wilson, who was acting as cook, was up and astir at his duties in the cook-house. The others slept; but I arose and followed by Nobs went down to the stream for a plunge. As was our custom, I went armed with both rifle and revolver; but I stripped and had my swim without further disturbance than the approach of a large hyena, a number of which occupied caves in the sand-stone cliffs north of the camp. These brutes are enormous and exceedingly ferocious. I imagine they correspond with the cave-hyena of prehistoric times. This fellow charged Nobs, whose Capronian experiences had taught him that discretion is the better part of valor—with the result that he dived head foremost into the stream beside me after giving vent to a series of ferocious growls which had no more effect upon _Hyaena spelaeus_ than might a sweet smile upon an enraged tusker. Afterward I shot the beast, and Nobs had a feast while I dressed, for he had become quite a raw-meat eater during our numerous hunting expeditions, upon which we always gave him a portion of the kill. Whitely and Olson were up and dressed when we returned, and we all sat down to a good breakfast. I could not but wonder at Lys’ absence from the table, for she had always been one of the earliest risers in camp; so about nine o’clock, becoming apprehensive lest she might be indisposed, I went to the door of her room and knocked. I received no response, though I finally pounded with all my strength; then I turned the knob and entered, only to find that she was not there. Her bed had been occupied, and her clothing lay where she had placed it the previous night upon retiring; but Lys was gone. To say that I was distracted with terror would be to put it mildly. Though I knew she could not be in camp, I searched every square inch of the compound and all the buildings, yet without avail. It was Whitely who discovered the first clue—a huge human-like footprint in the soft earth beside the spring, and indications of a struggle in the mud.
