As the door was opened and Frank jumped out there came a sudden cry of fire and out from a dark doorway plunged two figures. They were Chinamen, and they fled across the street. Near at hand was a Chinese laundry. From somewhere over the laundry came the muffled cries of fire. “This is the place!” panted Inza, pointing. “See—there is the doctor’s sign! His office is up there somewhere! Ah! Look! look! It’s all afire inside! Walter—he is in there! Save him! save him!” Behind the curtains which had been drawn at the upper windows there was a hideous red glare. “Fire!” shouted Diamond. “Come on!” rang out Frank’s voice. “Take care of her, somebody! The other one come with me!” Merry had decided that the doctor’s office must be on the first floor above the laundry, but there he found himself in a dark corridor and he could not seem to tell from what direction the cries came. He paused a moment to try to locate them, and then felt his way forward with his hands. “Where are you?” he shouted, at the top of his voice. Smoke was beginning to creep into the corridor. Then he saw a gleam of light through a crack, and, a moment later, he found a door. From beyond that door came the cries. Merry tried to open it, but it was locked. Then he backed off and flung his shoulder against it with all the force he could muster. There was a splintering crash, and he reeled headlong into the room where the fire was raging. The place was filled with smoke, through which the flames looked yellow and tigerish. Immediately Merry dropped on his knees to get beneath the mass of smoke, which filled the room. “Help!” Through the haze he saw two forms stretched prostrate on the floor, and he crawled toward them. “He is there!” he told himself. “She loves him!” Two men lay on the floor, bound hand and foot. One had been struck over the head and was bleeding and unconscious. The other did not seem to be injured, and he it was who had uttered the cries. It was the man Inza called “Walter.” Without doubt the other man was the crazy doctor. “You!” cried Frank, looking into the eyes of the man. “She brought me here to rescue you!” “Well, you’re just in time, Merriwell,” said the other. “You’ll have to hustle to do the little job, for that fire is spreading nicely.” Frank was appalled by one mad thought which clutched him. He might rescue the old doctor and leave this fellow for the time. Of course, if he got out safely with the doctor he could come back for the other man. Why should he not do this? He was in no way bound to save the fellow whom Inza loved. Yes he was! He had given her his word, and Frank Merriwell never broke his word, no matter what the result. Then Merry caught up the stranger and staggered to his feet, starting for the door, which was not easy to find again. He succeeded, however, and ran full into Starbright, who had followed him.
