"Do you see that light?" he asked. "In the window on the second floor?"
He took out his watch and noticed the time. It was just a quarter to twelve. He laughed softly to himself and said--
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.
"Well?" she said, with a laugh of amusement, and the quiet monosyllable, falling as it were with a cold splash upon his enjoyment of the little scene, suddenly brought him back to the question which was always latent in his mind. How was Pamela to be awakened?
"It's a strange place, London," he said. "No doubt it seems stranger to me, and more full of interesting people and interesting things just because I have come back from very silent and very empty places. But that house always puzzled me. I used to have rooms overlooking this square, high up, over there," and he pointed to the eastern side of the square towards Berkeley Street, "and what we have seen to-night used to take place every night, and at the same hour. The light went up in the room on the second floor, and the truants crept out. Guess where they go to! The Savoy. They go and sit there amongst the lights and the music for half an hour, then they come back to the dark house. They live in the most curious isolation with the most curious regularity. There are three of them altogether: an old man--it is his light, I suppose, which went up on the second floor--and those two. I know who they are. The old man is Sir John Stretton."
