meanwhile flattered himself by the thought that the other was trying to read his thoughts by looking at him fixedly. "I have been away from home," said Bruce at last. "I had occasion to go to the South of France." "I thought so. I was sure of it. How do you manage always to get ahead of us?" Mr. White was enthusiastic in his admiring divination. "You have heard about Sydney H. Corbett?" said the barrister, still keeping that inscrutable, calculating gaze upon the policeman. "Yes. I am on his track.

Bruce smiled cynically at the thought that he was actually shielding Lady Alice's probable slayer from the minions of the law. He marvelled at himself for his irresolution. Nevertheless, he
