That was not right either. She ought to be interested in persons. Warrisden rose abruptly from his chair. He was completely baffled. Pamela was like the sleeping princess in the fairy tale, she lay girt about with an impassable thicket of thorns. She was in a worse case, indeed, for the princess in the story might have slept on till the end of time, a thing of beauty. But was it possible for Pamela, so to sleep to the end of life, he asked himself. Let her go on in her indifference, and she might dwindle and grow narrow, her soul would be starved and all the good of her be lost. Somehow a way must be forced through the thicket, somehow she must be wakened. But he seemed no nearer to finding that way than he had been two years ago, and she was no nearer to her wakening. "No, there has been no change," he said, and as he spoke his eye was caught by a bright light which suddenly flamed up in the window of a dark house upon his right. The house had perplexed him more than once. It took so little part in the life of the square, it so consistently effaced itself from the gaieties of the people who lived about. Its balconies were never banked with flowers, no visitors mounted its steps; and even in the daytime it had a look of mystery. It may have been that some dim analogy between that house and the question which so baffled him arrested Warrisden's attention. It may have been merely that he was by nature curious and observant. But he leaned forward upon the balcony-rail. "Do you see that light?" he asked. "In the window on the second floor?" "Yes." He took out his watch and noticed the time. It was just a quarter to twelve. He laughed softly to himself and said-- "Wait a moment!" He watched the house for a few minutes without saying a word. Pamela with a smile at his eagerness watched too. In a little while they saw the door open and a man and a woman, both in evening dress, appear upon the steps. Warrisden laughed again. "Wait," he said, as if he expected Pamela to interrupt. "You'll see they won't whistle up a cab. They'll walk beyond the house and take one quietly. Very likely they'll look up at the lighted window on the second floor as though they were schoolboys who had escaped from their dormitories, and were afraid of being caught by the master before they had had their fun. There, do you see?" For as he spoke the man and the woman stopped and looked up. Had they heard Warrisden's voice and obeyed his directions they could not have more completely fulfilled his prediction. They had the very air of truants. Apparently they were reassured. They walked along the pavement until they were well past the house. Then they signalled to a passing hansom. The cab-driver did not see them, yet they did not call out, nor did the man whistle. They waited until another approached and they beckoned to that. Warrisden watched the whole scene with the keenest interest. As the two people got into the cab he laughed again and turned back to Pamela.
