"My name is Harror," Silver Mask said. "You're not going anywhere for the time being, and while you are here I'll thank you to call me _Mr._ Harror. Don't try to leave this car. My men are stationed all around the train with orders to shoot and look afterward. Take a look outside in a few minutes. You may be surprised." He turned and stooped to go through the door. Blake turned to Ferrell and O'Toole. "I haven't got the drift of all this yet," he admitted. "But we're in for trouble and plenty of it." * * * * * Blake was sitting quietly in the smoker, head reclining on the window ledge, eyes half closed in a cloud of smoke. The girl and her father were asleep. O'Toole pretended to be, but Blake wasn't sure of the Irishman. O'Toole slept with one eye open most of the time. The deep silence and blackness outside of the window could indicate only one thing. They were in some sort of a cave. The giant Harror had said if they looked out, they might be surprised. Yet, hours had passed, and the place was quiet and black as a tomb. The door opened and a newspaper flopped on the floor. Blake went forward and picked it up. "Thought you'd like to see the big news." It was Harror's heavy voice rumbling from the doorway. "Flown in from South Station. We've been waiting to see what reaction the kidnaping of a train might have." Blake listened quietly, and without a word turned on his heel and returned to his chair. The door closed on them again. Blake glanced at the headline. Then the full significance of Silver Mask's latest move hit him between the eyes. The headline of the South Station Star was in letters six inches high: MONO FLYER MISSING Entire Train Lost Without Trace Mono 6, crack flyer of the "Hope to Horn" mono line disappeared from the face of the earth tonight. On board were Walter Ferrell, the company's owner, and Dauna, his daughter. At an emergency meeting of the board of directors, it was admitted that not the slightest clue to the train's whereabouts has been discovered. Soon after midnight, Mono 6 of the west coast's crack Mono Line left Hope, Alaska. No further reports came after it passed the first five-hundred-mile zone. Reports of a wreck are unconfirmed. A complete search of the track failed to bring to light the slightest hint of the flyer's final resting place. In the past few hours the company has faced the problem of handling thousands of tour cancellations. Officials of the line are attempting vainly to allay the fears of both would-be passengers and stockholders. Wade Blake, Vice President of the company had previously ordered an investigation in an attempt to track to earth the series of strange accidents that have followed the Hope to Horn mono line for some months, but cannot be located at present for a statement.
