“All right. Good night,” said Joe. He turned back across the ragged and sodden lawn and gained the road. There he dared one brief backward look. Boy and dog still stood where he had left them, unmoving, silent, two dark forms in the falling darkness. The light in the house had gone, but that in one of the outbuildings――possibly a stable――had increased in brilliancy. Against its radiance a figure――two figures――moved, coming and going from sight across the square opening of a wide doorway. Then Joe brought his eyes back to the uneven road and floundered on toward the road and his bicycle. His thoughts were very busy indeed as he pushed and pedaled his way home. It was quite dark by the time he swung into his own street, and the infrequent lights left pockets of gloom between them. It was in one of these that a voice came to Joe above the swishing sound of his tires on the wet asphalt. “Hey!” said the voice imperatively. “Hold up!” Joe obeyed, coming to a halt as a dark figure detached itself from the deeper darkness across the street. The figure resolved itself into the burly form of a policeman who, joining the boy, peered suspiciously from him to the bicycle. “What’s it?” asked Joe. “Whose wheel is that?” demanded the officer gruffly. “Mine,” replied Joe. “That is, it belongs to Donaldson and Burns. They let me use it.” “What’s your name? Where do you live?” Joe told him, explaining his errand and indicating the wire carrier as confirmatory evidence, and the officer grunted as though satisfied and went on. So did Joe, arriving home a minute later very wet and very hungry; and also secretly rather excited. He had difficulty getting to sleep that night. The next morning three more bicycles were reported stolen and the papers carried an advertisement inserted by a hastily formed “Bicycle Dealers’ Association” offering a reward of one hundred dollars for information leading to the apprehension and conviction of the thieves. Joe read that notice with a deal of interest. He would have liked a partner in his contemplated enterprise, but the only fellow he could think of was Sam, and there were reasons why Sam wouldn’t answer. When he reached the store Joe sought Mr. Burke and asked to be allowed to leave a half hour earlier to-day. The manager objected from force of habit, but finally consented. At half-past four Joe begged some meat trimmings from the hand butcher, detached the parcel carrier from his bicycle and set off.
