Burton asked a number of questions in an effort to fix the identity of some of the gang, warned Jeb to telephone him at Jonas Prim's if he saw anything further of the strangers, and then retraced his steps toward the car. Not once had Jeb mentioned the youth who had purchased supplies from him that morning, and the reason was that Jeb had not considered the young man of sufficient importance, having cataloged him mentally as an unusually early specimen of the summer camper with which he was more or less familiar. Willie, on the contrary, realized the importance of their morning customer, yet just how he was to cash in on his knowledge was not yet entirely clear. He was already convinced that HOW TO BE A DETECTIVE would help him not at all, and with the natural suspicion of ignorance he feared to divulge his knowledge to the city detective for fear that the latter would find the means to cheat him out of the princely reward offered by the Oakdale village board. He thought of going at once to the Squibbs' house and placing the desperate criminals under arrest; but as fear throttled the idea in its infancy he cast about for some other plan. Even as he stood there thinking the great detective and his companions were entering the automobile to drive away. In a moment they would be gone. Were they not, after all, the very men, the only men, in fact, to assist him in his dilemma? At least he could test them out. If necessary he would divide the reward with them! Running toward the road Willie shouted to the departing sleuth. The car, moving slowly forward in low, came again to rest. Willie leaped to the running board. “If I tell you where the murderer is,” he whispered hoarsely, “do I git the $50.00?” Detective Burton was too old a hand to ignore even the most seemingly impossible of aids. He laid a kindly hand on Willie's shoulder. “You bet you do,” he replied heartily, “and what's more I'll add another fifty to it. What do you know?” “I seen the murderer this mornin',” Willie was gasping with excitement and elation. Already the one hundred dollars was as good as his. One hundred dollars! Willie “Goshed!” mentally even as he told his tale. “He come to our house an' bought some vittles an' stuff. Paw didn't know who he wuz; but when Paw went inside he told me he was The Oskaloosie Kid 'n' thet he robbed a house last night and killed a man, 'n' he had a whole pocket full o' money, 'n' he said he'd kill me ef I told.”
