"I should rather ask that question of you," said Dan drily. "Sir Charles is dead and buried these many weeks, and the woman who assassinated him can't be found, in spite of the reward and the effort of the police. Why, at this late hour, do you wish to rake up stale news? I thought that _The Moment_ was more up-to-date." "It will be very much up-to-date when the next murder is committed," observed Laurance, grimly and significantly. The legs of Dan's chair grated, as he pushed back in sheer surprise. "What do you mean by the next murder?" he demanded sharply. "Well, this gang----" "Gang! gang! Who says there is a gang?" and Dan's thoughts flew back to Durwin's reason for visiting Sir Charles. "Humph!" growled Laurance, thrusting his hands into his pockets. "I'm disappointed. I thought you knew more." "I know a good deal," retorted the other quickly, "but I don't intend to talk to you about what I know until I learn your game." "What about your own?" "That comes later also," said Halliday promptly. "Go on! I want to know why you rake up Moon's murder." "Naturally you do, seeing you are engaged to the daughter." "Am I? I am not quite sure. She loves me and I love her, but the new baronet wants her to marry Lord Curberry. She refused, and I kicked up a row some hours back. Result, we are on probation for one year, during which time I am to discover the assassin of Sir Charles." "And if you don't?" "Time enough to talk about that when I fail," said Halliday coolly; "at least I have twelve months to hunt round. I came for your help, but it seems that you want mine. Why?" Freddy, through sheer absence of mind, flung away a half-smoked cigarette and lighted another. Then he rose and strolled across the room to lean his shoulders against the mantelpiece. "We can help one another, I think," was his final observation. "I hope so. In any case I intend to marry Lillian. All the same, to pacify Sir John, I am willing to become a detective. You know my game. Yours?" "Listen," said Laurance vivaciously. "I forgot all about the murder, since there seemed to be no chance of the truth coming to the light, and so did every one else for the same reason. But a few nights ago I was dining out, and met a chap called Durwin----" "Scotland Yard man," interrupted Dan, nodding several times. "He came to see Sir Charles on business and found the corpse." "Just so. Well, after dinner we had a chat, and he told me that he was anxious to learn who killed Moon, because he didn't want any more murders of the kind to happen--as a police official, you understand." "Strange he should be confidential on that point," murmured Halliday thoughtfully, "seeing that he wished his theory regarding a possible gang kept quiet, in the hope of making discoveries." "He has changed his mind about secrecy, and so has Tenson," said Freddy. "Oh!" Dan raised his eyebrows. "The Inspector. You have seen him also?"
