He opened the second message with a preoccupied air. He was thinking--thinking deeply. But in a moment all his preoccupation vanished as he glanced over its contents. He hungrily devoured the words written on the tinted paper. "Am delighted at your promotion. I anticipated it. My most heartfelt good wishes. Do not let this success make you forget our meeting. Dare I hope that you may find your way to 17, Streamside Mansions, Kensington?--Vita Vladimir." It was some moments before Ruxton's eyes left that message. A world of unsuspected emotion was stirring within him. He had not forgotten. He was never likely to forget. But in the midst of his emotion some freak of mind had caught and held the significance of this mysterious creature's congratulations. How--how had she learned of--his promotion, when no one but himself and the Prime Minister knew of it? Suddenly he bestirred himself. He carefully refolded Vita's message, and placed it in his pocket. Then he turned to Heathcote. "I shall have to go to Dorby to-night. My father wants me. It is rather important. Fortunately things here will not require me just now. But you must notify me of anything important happening. Meanwhile give orders to have my things got ready, and look me out a train. I must run out to send a wire." "Can't I send it for you?" "No-o. I think not, thanks." CHAPTER IV MR. CHARLES SMITH A profound silence reigned in the library at Dorby Towers. The pungent aroma of cigars weighed upon the atmosphere in spite of the wide proportions of the apartment. Considerable light was shed from the antique sconces upon the walls, as also by the silver candelabra upon the long refectory table which ran down the centre of the room. But withal it was powerless to dispel the dark suggestion of the old bookcases which lined the walls of the room. Two men were occupying one side of the table, and Ruxton Farlow sat alone at the other. The eyes of all three were focussed intently upon the object lying upon the table, which was a ten-foot model of a strange-looking water craft. The first to break the spell of the burden of silence was Sir Andrew Farlow, who, with a bearded stranger, occupied the side of the table opposite his son. But his was no attempt at speech. He merely leant forward with an elbow on the polished oak, and his fingers softly stroking his square chin and tightly compressed lips. He was humming softly, an expression of an intently occupied mind. The fixity of his gaze suggested a desire to bore a way to the heart of the secrets the strange model contained.
