"Saul Arthur Mann?" she repeated, "I seem to know that name. Mann, Mann! Where have I heard it?" "Well," said he, with that fierce and fleeting little smile which rarely lit his face for a second, "if you don't know him he knows you; he knows everybody." "Oh, I remember! He is 'The Man Who Knows!'" It was his turn to be astonished. "Where in the world have you heard of him?" Briefly she retailed her experience, and when she came to describe the omniscient Mr. Mann--"A crank," growled Mr. Minute. "I was hoping there was something in it." "Surely, uncle, there must be something in it," said the girl seriously. "A man of the standing of the chief commissioner would not speak about him as Sir George did unless he had very excellent reason." "Tell me some more about what you saw," he said. "I seem to remember the report of the inquest. The dead man was unknown and has not been identified." She described, as well as she could remember, her meeting with the knowledgable Mr. Mann. She had to be tactful because she wished to tell the story without betraying the fact that she had been with Frank. But she might have saved herself the trouble, because when she was halfway through the narrative he interrupted her. "I gather you were not by yourself," he grumbled. "Master Frank was somewhere handy, I suppose?" She laughed. "I met him quite by accident," she said demurely. "Naturally," said John Minute. "Oh, uncle, and there was a man whom Frank knew! You probably know him--Constable Wiseman." John Minute unfolded his napkin, stirred his soup, and grunted. "Wiseman is a stupid ass," he said briefly. "The mere fact that he was mixed up in the affair is sufficient explanation as to why the dead man remains unknown. I know Constable Wiseman very well," he said. "He has summoned me twice--once for doing a little pistol-shooting in the garden just as an object lesson to all tramps, and once--confound him!--for a smoking chimney. Oh, yes, I know Constable Wiseman." Apparently the thought of Constable Wiseman filled his mind through two courses, for he did not speak until he set his fish knife and fork together and muttered something about a "silly, meddling jackass!" He was very silent throughout the meal, his mind being divided between two subjects. Uppermost, though of least importance, was the personality of Saul Arthur Mann. Him he mentally viewed with suspicion and apprehension. It was an irritation even to suggest that there might be secret places in his own life which could be flooded with the light of this man's knowledge, and he resolved to beard "The Man Who Knows" in his den that afternoon and challenge him by inference to produce all the information he had concerning his past.
