A taunting wicked smile crossed the Lascar's lips, but it was gone a moment afterwards. It might have been the shadow of an evil thought finding expression there. "How does he haunt you more than you have already told me he does?" demanded Joshua in a great heat. "You don't think he can frighten me as he frightens you, Susan, do you? The black dog! Look at him! He's frightened of a white man's little finger!" "Hush!" implored Susan. "He haunts me when he is not near me." "How can he do that, you foolish girl?" "He does it--he _can_ do it--with his double!" "His double?" "He has a double--a spirit, a wicked spirit"--she turned her head slowly and trembled in every limb; "and he told me it should haunt me, and follow me wherever I go. And it does! I feel it behind me when I don't see him. It is there now! It is there now!" And wrought to the highest pitch of mental terror and excitement, Susan threw up her hands, and would have fallen to the ground but for Joshua's protecting arm. The taunting smile came again upon the Lascar's lips, as he secretly watched Susan's terror. With a special maliciousness he flashed his fingers towards her, as if he were issuing a command to his double not to leave her. It was evidence of the power he possessed over her weak mind that, notwithstanding her almost fainting condition, a stronger shuddering came upon her when he made even that slight motion. Feeling that, for Susan's sake, it was necessary to put an end to the scene, Joshua, with an indignant motion, commanded the Lascar to leave them. The Lascar rose submissively, like a whipped dog, and so stood with bent head before Joshua. "Now then, what are you waiting for?" asked Joshua. "My knife," answered the Lascar doggedly. "Not likely," said Joshua; "I know you too well to let you have it." "What do you know of me?" asked the Lascar in a low guttural voice. "I have heard enough of you from Mr. Meddler"--the Lascar grated his teeth with tigerish ferocity--"you and the likes of you. I know how free you are with your knives, you Lascars, on land and on sea. Be off!" "My knife!" again demanded the Lascar, with his eyes directed to Joshua's feet; but he saw Joshua's face and every motion of Joshua's body. "My knife! It is mine. I bought it and paid for it." "Stole it more likely," said Joshua with a sneer. "It is a lie. I bought it. Even if I did steal it, you have no right to it. Give me my knife, and let me go."
