He stopped short as Marie Pascal with a sudden movement flung down the screen. The King in amaze stood stock still while the young girl looked at him in utter stupefaction, with trembling lips and body shaken by nervous tremors. Then suddenly she turned in terror, screaming: "Help! Help! The impostor! The murderer!... the King is not the King.... Frederick-Christian has disappeared!... Who is this man?" The girl's cries brought the Hotel servants quickly to the scene. She continued, pointing to the King: "Who is this man?... Frederick-Christian has disappeared!... good God, what has happened?" "Better call the police," suggested some one. This met with general approval, but proceedings were suddenly interrupted by the arrival of Wulf. "Have you heard?" several voices asked. "All I know," replied Wulf in a piteous tone, "is that Frederick-Christian or not, he's got a devilish heavy foot, and when he kicks, he kicks royally." CHAPTER XXI HORRIBLE CERTAINTY "What has happened to that idiot Juve? Here for three days I've been shut up in this beastly prison and no sign of him." As the days passed, Fandor gradually lost his buoyancy of spirits and became more and more anxious. "What can Juve be doing?" he repeated for the hundredth time. The continual obscurity of the place began to weigh him down. This was relieved each day for a few moments by a thin shaft of light. Fandor was quick to account for the phenomenon. "It happens exactly at noon when the sun is directly overhead," he reasoned, "and finds an entrance through a crack in the bronze." Many times he climbed to the body of the naiad in the hope of discovering some method of escape, but at length he realized that the thing was impossible. He was seated one night deep in thought, puzzling his brains for the reason of Juve's defection, when a voice suddenly broke the silence. "Can you hear me?" Fandor bounded to his feet. "Yes, I hear you." "You must be getting uneasy?" "Uneasy! I'm going mad! What a long time you've been!" "That's true, I am a little late, but it hasn't been very easy." Now that Fandor's mind was set at rest about his deliverance, he grew curious to know the results of the detective's investigation. "Well, you were successful?" "Yes, quite successful." "Do they know in Glotzbourg?" "They must have some suspicion by now." "When did you get back?" "This morning." "Only this morning! And did you get my letter?" "Your what, Sire?... I don't catch." "I say you must have got my letter, since you are here, and now please get me out of this hole as quickly as possible ... it's awful being shut up here ... you can't imagine how I long for a breath of fresh air." "Yes, yes, I understand, but I'm wondering how I'm to get you out." "What's that?" "Have you thought over a way we can effect the exchange?" "But, my dear fellow, you must know what to do. I gave you full particulars in my letter." "In your letter?" "Yes.... I even enclosed a diagram."
