"My good Merritt, I have not the slightest doubt about it. My plans are too carefully laid for them to go astray. But, at the same time, I firmly believe in having more than one plan of attack and more than two ways of escape. If we could have despoiled Bell of his picture it would have been utterly useless for him to have come here. He would have gone back preferring to accept defeat to arriving with a cock-and-bull story to the effect that he had been robbed of his treasure on the way. And so he got the best of you, eh?" "Rather! I fancied that I was pretty strong, but--well, it doesn't matter. Here I am with the tools, and I ain't going to fail this time. Before Bell comes the little trap will be ready and you will be able to prove an alibi." Henson chuckled hoarsely. He loved dramatic effect, and here was one to hand. He almost fancied that he could see the white outline of Chris's figure from where he stood. "Get along," he said. "There is no time to lose." Merritt nodded and began to make his way upward. Some way above him Chris was looking down. Her quick ear had detected some suspicious sound. She watched eagerly. Just below her the big electric light on the castle tower cast a band of flame athwart the cliff. Chris looked down steadily at this. Presently she saw a hand uplifted into the belt of flame, a hand grasping for a ledge of rock, and a quickly stifled cry rose to her lips. The thumb on the hand was smashed flat, there was a tiny pink nail in the centre. Chris's heart gave one quick leap, then her senses came back to her. She needed nobody to tell her that the owner of the hand was James Merritt. Nor did she require any fine discrimination to perceive that he was up to no good. That it had something to do with the plot against Bell she felt certain. But the man was coming now, he could only reach the top of the cliffs just under the wall where she was standing. Chris peered eagerly down into the path of light until the intruder looked up. Then she jerked back, forgetting that she was in the darkness and absolutely invisible. The action was disastrous, however, for it shook Chris's diamond star from her head, and it fell gently almost at the feet of the climber. An instant later and his eyes had fallen upon it. "What bloomin' luck," he said, hoarsely. "I suppose that girl yonder must have dropped it over. Well, it is as good as a couple of hundred pound to me, anyway. Little missie, you'd better take a tearful farewell of your lumps of sugar, as you'll never see them again." To Chris's quivering indignation he slipped the star into his breast-pocket. Just for the moment the girl was on the point of crying out. She was glad she had refrained a second after, for a really brilliant thought occurred to her. She had never evolved anything more clever in her life, but she did not quite realise that as yet.
