must learn who killed him,” Mr. Mason reiterated. “Why, Chief Martin, if the police fail to track down the slayer of Amos Gately, it will be a blot on their record forever! Spare no effort,—put your best men on the case, move heaven and earth, if need be, but get your man! The Company will back you to the full extent of its power; we will offer a reward, when the suitable time comes for that.
