They rounded a curve in the road, and there, miraculously, the lighted cabin rose before them. “At last!” exulted Louise. “The Promised Land!” Staggering up a shoveled path, they pounded on the cabin door. An old man, who held a kerosene lamp, responded promptly. “Come in, come in!” he invited heartily. “Why, you look half frozen.” “Looks aren’t deceitful either,” Penny laughed shakily.
