There was the crackle of a match, and the elder man uttered a cry of horror as he shrank into his corner again, but as the wax taper burned up steadily in Arthur's fingers, and no explosion followed, he obeyed his companion's order and picked up the lamp, which proved not to be utterly drained of oil, and after a little patient effort began to burn again as it was replaced in the broken lantern. "Now, then, sharp's the word," said Arthur. "Hold the light while I chisel out the wood till I can get at the lock. Mustn't use the hammer, or it will put her on her guard. Wonder whether she's outside listening." There was not a sound to be heard, and with Roach tremblingly holding the light, Arthur worked away with the sharpest-edged wedge, but made little progress, for a few cuts were sufficient to prove that the door was of the hardest oak, and when the man had been carving away for nearly an hour, with the perspiration streaming down his face, it was to throw down the chisel in despair, for the wood proved to be only the casing of an iron door of great strength. "Give me the bottle," said Arthur, panting. "Can't you do something beside shivering there?" Roach groaned as he handed the bottle. "Man wants a bit o' Dutch courage over a job like this." "We shall never get out," groaned Roach. "Not if it's left to you, old man. You'd turn it into a tomb at once. Here, I've left you a drop. Tip it off, and see if it'll put some pluck into you. There, I've tried fair play and quiet; now it's got to be foul play and noise. Give me hold of the hammer and let's see what a wedge'll do." "Hist! What's that?" Arthur needed no telling to be silent. Snatching the light from his companion, he reached over to the portmanteau and took out the two small revolvers, handed one to his companion, and whispered to him-- "It was the lock. Someone coming. Don't fire without you're obliged. I'll try the hammer first." As he spoke he blew out the little lamp, and set it down, before standing facing the door with his hand raised, ready to strike down the first who entered. Some minutes must have elapsed without further alarm, and the two men were ready to believe that the sharp snap they had heard must have come from the iron door of the closet, the frame springing back after being strained by the application of the wedges that had been driven in. All at once, just as an attack was about to be made once more upon the way by which they had entered, and Arthur had taken a fresh match from his box, a soft light began to dawn, grew rapidly, and dazzled their eyes, as they strove to make out whence it came, and stood ready once more to strike.
