"If it _should_ be he!" thought I, as I emerged into the street. The bare suspicion had sent the blood through my veins with furious violence. "If this Sandford be, as I suspect, that villain Cardon, success will indeed be triumph--victory! Lady Everton need not in that case seek to animate my zeal by promises of money recompense. A blighted existence, a young and gentle wife by his means cast down from opulence to sordid penury, would stimulate the dullest craven that ever crawled the earth to energy and action. Pray Heaven my suspicion prove correct; and then, oh mine enemy, look well to yourself, for the avenger is at your heels!" Sandford, I had been instructed was usually present at the Italian Opera during the ballet: the box he generally occupied was designated in the memoranda of the police: and as I saw by the bills that a very successful piece was to be performed that evening, I determined on being present.

"Waters!" he at last stammered, feebly accepting my proffered grasp--"who would have thought of meeting you here?" "Not you, certainly, since you stare at an old friend as if he were some frightful goblin about to swallow you. Really"---- "Hush! Let us speak together in the lobby. An old friend," he added in answer to Mr. Merton's surprised stare. "We will return in an instant." "Why, what is all this, Waters?" said Cardon, recovering his wonted _sang-froid_ the
