"We must oil it first," Wilfrid said. "Come upstairs and get some oil. You can't expect to use a key after all that time. Then we will return and you shall show me your treasures."

Flower obeyed instantly. His limbs staggered under him. It was as much as Wilfrid could do to get him upstairs and into the bed-room again. For a moment Flower clung tenaciously to his keys, but they dropped unheeded on the floor and his eyes closed again, as if his exertions had overpowered him. When he was between the sheets, the strange look of coma came over him again. How quiet the house seemed! Then, as he was feeling the tense stillness of it all, his ear caught the sound of a footstep on the gravel and a moment later there was a tinkle of pebbles on the window.

CHAPTER XL

TOWARDS THE LIGHT

Russell stood by the side of Uzali waiting for developments. They were still in the shade of the portico outside the music-hall, and it was Uzali's part to play the next card. But he remained perfectly motionless, though Russell could see his eyes gleaming and that he was moved by some strong feeling. At the same time, Russell had no fear and no anxiety. He felt the thing was in capable hands and that Uzali would not spoil the situation by undue haste.

"What are you going to do?" he whispered.

"For the moment, nothing," Uzali said grimly. "We are going to pursue what one of your greatest statesmen used to call a policy of masterly inactivity. In other words, we will follow Mr. Jansen and my countryman and ascertain what deep scheme they have on hand. Unless I am mistaken Jansen is as much in my debt as Samuel Flower. But we can go into that later. Just now we have to keep those fellows in view and watch them all night if necessary."

Russell had no objection. He felt that action was blessed and that his dogged patience and perseverance were about to be rewarded. Few words were spoken as he and his companion turned and followed Jansen at a respectful distance until Gray's Inn Road was reached. Here Jansen paused and appeared to take a latch-key from his pocket. A door was quietly opened and shut and then the watchers had the street to themselves. Uzali turned eagerly to Russell.

"You marked the right house?" he asked.

"Oh, I think I know the house," Russell replied. "I have had a very good description of it and here comes Goatley to see that we are on the right track. Well, what is it, Goatley?"
