Irritated by this speech--for Penn knew very well of the rivalry--Dan became scarlet. "I shall discover the truth. Lord Curberry need not trouble himself." "If you discover the truth----" began Penn, and hesitated. "Well?" asked Halliday sharply. "I think Lord Curberry will certainly marry Miss Moon." "What do you mean by that?" demanded Dan, but Penn gave no answer. Shaking his head significantly, he stepped back, and in one moment was lost in the midst of the crowd which thronged the corner. Halliday would have followed, for the man's last observation seemed to hint that he knew more about the truth than he was disposed to admit; but many people came between him and the secretary, so it was impossible to get hold of him again. Dan was forced to walk on alone and he walked on pondering deeply. Did Penn know the truth? It seemed impossible that he should know it. The evidence of the typewriting girl went to show that he had not left his private room all the evening until summoned by Durwin when the death was discovered. What Penn said about the perfume appeared to be reasonable enough, as he certainly had handled the body, and if reeking of the scent--as he was reeking on this very day--it was not surprising that the odor should communicate itself to the dress clothes of the dead man. Some odors cling very powerfully, and endure for a considerable time. This Sumatra scent assuredly had done so, for it was quite three hours after the death that Dan himself had seen the corpse, and even then he had smelt the perfume. However, on the face of it, Halliday saw no reason to doubt Penn's statement, and quite understood how he became, through Sir John's mediation, the secretary of Lord Curberry. Only the last speech of the secretary was strange. Why should he say that, if the truth were discovered by Dan, Curberry would marry the girl, when, on the discovery of the truth--so far as Dan could see--the marriage of himself to Lillian depended? Dan could find no answer to this question, and had half a mind to follow Penn to his new employer's house, so as to force an explanation. But as he knew Curberry did not like him, he decided to let matters stand as they were, and only reveal what he had heard to Laurance.
