"I think that is all we can do at the moment," he said, addressing the party. "It is quite evident that a great insurance conspiracy has been attempted, and not for the first time. Apparently the late Mr. Martin was a victim, together with other persons, whose names and circumstances we shall later on discover. To me it seems that great credit is due to the intelligence of Miss Ramsay and of Mr. Durrant, who watched the man Boyne so ingeniously until they must have somehow betrayed themselves, and thus have placed their lives in jeopardy." "I think," said the Manchester solicitor, "that if Mrs. Braybourne had pretended to remain in ignorance for a month or so, and not sought to establish her claim, the company would have, no doubt, paid the sum without question." "Yes," laughed the superintendent. "But criminals always betray themselves by overdue anxiety. But we have here to deal with a very dangerous gang. and it only shows to the insurance world how easily they may be defrauded by a well-established organisation." Shaw had left the room, and already the telephone was at work to ensure the arrest of the criminals. "It will certainly be highly interesting to discover how many innocent people have actually been the victims of this desperate and relentless trio who dealt secret death in order to enrich themselves," remarked the superintendent. "There was a grave suspicion of the woman Pollen in another case about two years ago," said Macdonald. "Therefore, on a report from Ardlui, I ran up from Glasgow, but I failed to identify her as the woman who had called herself Slade, though I had very strong suspicions. Her social standing deceived me, I admit. Poor Mrs. Morrison of Carsphairn!" exclaimed Macdonald in his strong Glasgow accent. "She was a good lady—a very good lady!" "Well," said the superintendent, rising from his chair. "We have to thank you all for your combined efforts, and especially Mademoiselle and Mr. Durrant. Let’s hope we shall get the guilty ones, and then we shall all meet again as witnesses at the Old Bailey." And thus, just after five o’clock, he dismissed them, Gerald, excitedly and with all haste, making his way back to the bedside of his loved one in order to tell her the intentions of the police. At last the devilish crimes of the Red Widow and her accomplices were to be exposed, and the trio of death-dealers punished. *CONCLUSION* Scotland Yard is difficult to arouse, but when once actual evidence of crime is forthcoming it is quick of action. At half-past five that afternoon a small, under-sized man, who wore the uniform of the Metropolitan Water Board, rang at the basement entrance of the house in Pont Street, and the cook opened the door. "Well, missus?" he exclaimed merrily. "What’s the trouble with the water here—eh?" "Trouble? There’s no trouble," replied the cook, who never suspected that four other men were in close vicinity awaiting their leader’s call.
