But Georgia, leaning over the parapet and staring down into the darkness, saw more than the indeterminate outlines of rocks and sun-dried bushes. Her heart was in her mouth as she peered down the cliff, for she felt certain that she had seen something moving below, and that it, whatever it might be, was climbing the hazardous path she had noticed by daylight. Too much fascinated and horror-stricken to move, she remained leaning over the edge until Lady Haigh stepped out of the carved doorway behind her and startled her by speaking suddenly. “Oughtn’t you to be coming to bed, Georgie? It is very late, and you have had an anxious day. What are you looking at down there?” “Oh, Lady Haigh, there is some one--a man or several men--climbing up the cliff!” was the gasping answer, as Georgia turned round with a blanched face. Lady Haigh pushed her gently aside and looked over as she had done. “There is something there, certainly,” she whispered; “but it is almost sure to be only a goat.” Somewhat reassured, Georgia returned to her post of vantage, and side by side they watched together the upward progress of the dark body, until the sound of labouring breath reached them, showing that the climb must be a severe one. “It is a man,” said Lady Haigh. “Can they get quite to the top?” “No, about twenty feet down the cliff begins to slope outwards.” “Then we won’t alarm the gentlemen just yet. It may be only one of our own servants trying to discover us, and we don’t want him to fall into Abd-ur-Rahim’s hands. We shall soon see whether this man’s intentions are hostile.” “He has reached the ledge now,” gasped Georgia. “He is resting.” The mysterious visitor seemed inclined to make no further effort for the present, for he remained motionless during several anxious moments; but at last a very low, clear whistling became audible, to which Lady Haigh and Georgia listened in astonishment and trepidation. “It must be a signal,” whispered Georgia. “No,” she cried, suddenly, “I know that tune! It is the ‘Battle of the Boyne,’ and a minute ago it was ‘Derry Walls.’ Lady Haigh, it’s Mr Anstruther!” “Is it you, Mr Anstruther?” asked Lady Haigh, in a low voice. The answer came back promptly. “It is myself, very much at your service, Lady Haigh, if I could only get near enough to serve you. Are you all right?” “Quite safe at present,” returned Georgia; “but we have gone through some thrilling experiences during the day. How did you find us out?”
