being the directing hand, Corporal Ryan doing some important parts and Constable Pennycuick being the "Sherlock Holmes" genius whose keen detective instincts and arduous persistent work won high praise from the judge at the trial, being those mainly instrumental in bringing this cold-blooded and cruel murderer to justice. The Police have always had a free hand as to expense in the enforcement of law, and the O'Brien case ran up a bill of over $100,000. But the reputation built up throughout the years by these guardians of public safety, that they would get a criminal if they had to follow him to the ends of the earth, saved the Dominions uncounted expenditure in other ways, and established Canada in the opinion of the world as a country where desirable citizens could come, build homes, rear their families and pursue their avocations freer from molestation than in any other similarly situated place on the face of earth. And that was an enormous gain for a new land which needed immigrants to populate its vast territory and develop its immense latent resources. Somewhat briefly, the way the Police got O'Brien was in this fashion. The Police, as above mentioned, kept close "tab" on travellers by trail or river for the sake of their safety, and a few days after Olsen, Relphe, Clayson and O'Brien left Fossal's road-house at Minto, Sergeant Barker, who was in charge at Five Fingers, and who had been notified of their departure, wired to White Horse that the party had not been heard of since. And the wires were kept hot in all directions, while patrols also were sent out to locate the men who had not turned up at the usual points. At that time murder was not necessarily a theory connected with their disappearance. Nearly ten days after Christmas the alert Police at Tagish post saw a man with horse and sleigh making a detour of the trail on passing their quarters. This aroused their suspicion, and they gathered in the man and his outfit, after pulling them out of a hole in the ice to which the detour had brought them. The man said his name was O'Brien, but he was sullen and would say no more. They took no chances, but brought him before the commanding officer, who sentenced him to "six months" for vagrancy. Several big bank notes were found on his person, also packed in crevices on the sleigh, and also a strange nugget of gold, shaped like a human hand holding a smaller nugget. It was found out that O'Brien had displayed this nugget as a curiosity at a road-house a few nights before, and later on it was found that Relphe, one of the men who had vanished, had a penchant for curios, and amongst them had this nugget and a specially odd coin. Things were beginning to look interesting and, as Inspector Scarth wanted a man who answered O'Brien's description for robbing the cache of Mr. Hansen at Wolf's Island, O'Brien was sent up to Fort Selkirk and held on that charge. Then Sergeant Holmes (rather a curious coincidence in detective names)
