But why had either of them--mother or son--been concealed in the house that night? Could it have been Lady Brenton whose figure had flitted across the lawn before his startled eyes? True, it had worn a gold scarf and, according to her ladyship, at that moment she had not possessed such an article. Still, there was more than one kind of gold scarf in the world, and even Indian ones were quite easily obtainable. Then why had she been forced to introduce Gunga Dall to Lady Margaret when the child had been in Paris? Was there some power that the Hindoo possessed over the elder woman? All these thoughts raced through his mind--but---- And then of a sudden he became alert, for out of the silence of the night and in at the window again came the sound of footsteps tip-toeing softly by. Even as he stared out with sharp, discerning eyes, a figure flitted by. It was a figure that made Cleek's heart beat wildly for it was the figure of Sir Edgar Brenton himself! CHAPTER XXI "'TIS A MAD WORLD, MY MASTERS" For a minute the young man made neither sound nor movement, and Cleek was tempted to believe that his presence there was accidental--a mere trick of chance. But of a sudden, as he peered farther out, he caught a glimpse of Sir Edgar's face, and that one glance told him that here was no chance eavesdropper, but one whose hatred of the Hindoo presumably would carry him very near to murder now, if he had not already committed that act. His face was white with the passion that kills if need be, and his twitching hands and lips told their own story. As Cleek's eyes fell on a little shining instrument in one of those shaking hands, he knew it was time to act quickly. He leaned over just as Sir Edgar raised the revolver to aim at Gunga Dall's retreating figure and with a grip of iron grasped the boy by the shoulder. He swung his slim figure over the shallow window-sill and into the ballroom before you could say Jack Robinson. The strength of his muscles was extraordinary, and as the young man stood before him, sputtering in fury at this calm proceeding, Cleek gave a short, sharp laugh. "Took you rather by surprise didn't I, my friend?" he said as Sir Edgar turned upon him menacingly. "But quick thought demands quick action, and my apologies are manifold. Believe me----" "Who the devil are you and what are you doing here?" cut in Sir Edgar, angrily, trying to recognize the strangely contorted face of the man who stood guard over him. "Who am I?" replied Cleek, with a light chuckle. "Ah, my friend, more than you would like to have that question answered. What I am doing is another matter--preventing another murder, I fancy. Anyway----" He gave a quick spring and there came a swift rustle, a metallic click! The revolver was on the floor and a band of steel was locked about each of the young man's wrists. "You've put handcuffs on me," Sir Edgar cried out, angrily. "How dare you commit such an outrage! I'll have you arrested--I----"
