Professor Brierly had stood by, hands clenched, eyes flashing. They had started toward the hangar from which a man was running toward them, Matthews said, banteringly: "What do you think of the relative value of physical as against mental culture now, Professor. Know what these birds were after, don't you?" Professor Brierly said resolutely: "I have not changed my mind at all. I might have discussed it with them. I might have--" "Yeah," broke in Jimmy inelegantly. "As I once heard Jack say to you, you might have slugged 'em with your culture and logic." The old scientist glared. He burst out: "You are both--" "Yes, Professor," interrupted Matthews, "Jimmy certainly is, all that and then some. And Professor, did you have a good look at Jimmy's left eye. Me, oh my, what a mouse. WHAT a shiner." The three fell silent. Matthew's hand fell on Jimmy's shoulder as they approached the hangar. "I knew you were a good little man, Jimmy; I always said so. Your coach would have been proud of you if he could have seen it. You earned your letter, Jimmy." The hand increased its pressure on the shoulder, dropped, and there was no further allusion to the episode. Jimmy went into the hangar and put in two quick telephone calls, one to his office, where the dog watch was on duty, and one to Police Headquarters in New York City. To each he told the episode of the pseudo policemen. New York police headquarters promised that they would get in touch immediately with the State police and with the Pleasantville police. His office also promised immediate action. He learned later that when the police arrived there was no sign of their assailants. But other and more pressing matters engaged the attention of Professor Brierly and the reporter; matters that drove the fight out of their minds. A short drive took them to what had once been the home of William Flynn. They were at once admitted inside the police lines. McCall, from Canada, and Hite, from New York, had paved the way for them. The explosion had not been as severe as Jimmy had been led to believe. Two of the lower rooms remained nearly intact and some portions of the foundation. State, county and city police were there, in uniform and in plain clothes. Even at this hour a huge crowd had gathered. Newspaper representatives from all the New York papers from nearby towns and from news-gathering bureaus, were there. Two state troopers and one member of the Pleasantville police force had been on guard outside the house when the explosion occurred. The house was at the end of a quiet residential street. Beyond the house there was a patch of wooded ground which cut off the view from a state road running to Tarrytown, about a hundred yards deep. The house nearest to the one that had been wrecked by the explosion was two hundred yards distant. One of the state troopers who had been on guard outside the house was present when the three men arrived. His testimony was brief.
