MUSIC HATH POWER. For Mr. Montague Nevitt was a cautious, cool, and calculating person. He knew, better than most of us that knowledge is power. So when the manager mentioned to him casually in the way of business the names of Guy and Cyril Waring, Mr. Montague Nevitt didn't respond at once, "Oh, dear yes; one of them's my most intimate personal friend, and the other's his brother," as a man of less discretion might have been tempted to do. For, in the first place, by finding out, or seeming to find out, the facts about the Warings that very afternoon, he could increase his character with his employers for zeal and ability. And, in the second place, if he had let out too soon that he knew the Warings personally, he might most likely on that very account have been no further employed in carrying into execution this delicate little piece of family business. So Nevitt held his peace discreetly, like a wise man that he was, and answered merely, in a most submissive voice, "I'll do my best to ascertain where they bank, at once," as if he had never before in his life heard the name of Waring. For the self-same reason, Mr. Montague Nevitt didn't hint that evening to Guy that he had become possessed during the course of the day of a secret of the first importance to Guy's fortune and future. Of course, a man so astute as Montague Nevitt jumped at once at the correct conclusion, that Colonel Kelmscott must be the two Warings' father. But he wasn't going to be fool enough to chuck his chance away by sharing that information with any second person. A secret is far too valuable a lever in life to be carelessly flung aside by a man of ambition. And Montague Nevitt saw this secret in particular was doubly valuable to him. He could use it, wedge-wise, with both the Warings in all his future dealings, by promising to reveal to one or other of them a matter of importance and probable money-value, and he could use it also as a perpetual threat to hold over Colonel Kelmscott, if ever it should be needful to extort blackmail from the possessor of Tilgate, or to thwart his schemes by some active interference. So when Nevitt strolled round about nine o'clock that night to Staple Inn, violin-case in hand, and cigarette in mouth, he gave not a sign of the curious information he had that day acquired, to the person most interested in learning the truth as to the precise genealogy of the Waring family.
