CHAPTER XIX

WARNED!

Frank’s surmise was communicated to Captain Folsom, and the latter at once sent a radio message to the Custom House at New York, giving a bare outline of the details of the raid and asking that a watch be kept for Higginbotham. Custom House communicated with the New York Police Department, and a guard was set at the bridges and ferries leading from Long Island to Manhattan.

Several days elapsed, however, with Higginbotham still uncaught. Meanwhile the next day after that eventful night, the radio-controlled plane was found floating in the waters of Great South Bay, so near the shore as to make it practically impossible Higginbotham had been drowned but, on the contrary, to give rise to the belief that he had made his way ashore. A fisherman made the discovery.

It was some twenty-five miles as the crow flies from the Brownell place to the point where the airplane 173 came down. That, Jack estimated, when told of the discovery, probably was the limit of the radio plant’s radius of control. Higginbotham, therefore, had not descended until compelled to do so.

All this, however, did not come until later. Meanwhile, after saying farewell to the two officers, the boys returned afoot to their homes with the understanding on Jack’s part that Captain Folsom, the main portion of whose wardrobe still was at his house, would return later. On arrival, Jack learned that Tom Barnum already had explained the reason for his absence to the housekeeper and, after telling her Captain Folsom should be shown to his room on arrival, turned in and went instantly to sleep.

As for Bob and Frank, only the servants as yet were astir at the Temple home. And the boys, after stating only that they had been routed out by a fire at the airplane hangar, went instantly to bed.

Once Bob was partially awakened by Della, who demanded indignantly if he intended to sleep his young life away and commanded that he awaken Frank in order that she and her guest might have company. Bob merely grunted unintelligibly, and Della retired in a high state of indignation, resolved to give the boys a “piece of her mind” when finally they should arise.

That event, however, did not come to pass until 174 mid-afternoon. Bob on his sister’s departure the first time had gotten up and locked the doors of his room and that of Frank, which adjoined. Thus, although Della several times came to the door and knocked, she received no reply.
