Suddenly the sharp pricking pain in her arm ceased. She was conscious of a sensation as though her arm was being blown up like a bicycle tyre, but it was not unpleasant. He withdrew the needle and kept his finger pressed upon the little red wound where it had gone in.
"I shall do this to you again to-night," he said, "and you will not feel it at all, and to-morrow morning, and you will not care very much what happens. I hope it will not be necessary to give you a dose to-morrow afternoon."
"I shall not always be under the influence of this drug," she said between her teeth, "and there will be a time of reckoning for you, Dr. van Heerden."
"By which time," he said calmly, "I shall have committed a crime so wonderful and so enormous that the mere offence of 'administering a noxious drug'—that is the terminology which describes the offence—will be of no importance and hardly worth the consideration of the Crown officers. Now I think I can unfasten you." He loosened and removed the straps at her wrists and about her feet and put them in his pocket.
"You had better get up and walk about," he said, "or you will be stiff. I am really being very kind to you if you only knew it. I am too big to be vindictive. And, by the way, I had an interesting talk with your friend, Mr. Beale, this afternoon, a persistent young man who has been having me shadowed all day." He laughed quietly. "If I hadn't to go back to the surgery for the Bromocine I should have missed our very interesting conversation. That young man is very much in love with you"—he looked amusedly at the growing red in her face. "He is very much in love with you," he repeated. "What a pity! What a thousand pities!"
"How soon will this drug begin to act?" she asked.
"Are you frightened?"
"No, but I should welcome anything which made me oblivious to your presence—you are not exactly a pleasant companion," she said, with a return to the old tone he knew so well.
"Content yourself, little person," he said with simulated affection. "You will soon be rid of me."
