mean only one thing. He was busy on an important case.
Sensing his sonsâ curiosity, he said, âIâve been asked to help on an interesting problem which has the authorities baffled. Immigration officials have learned of the large-scale smuggling of aliens from India into the United States somewhere along the Atlantic coast. One suspected spot is Bayport.â
âBayport!â Frank repeated in astonishment, adding, âAny other clues?â
âNone. But maybe you boys can find some,â Mr. Hardy replied with a twinkle in his eye. âIâm working on another case right now that Iâll have to finish before I can concentrate on this smug gling racket.â
âIn other words, Dad, youâre asking Joe and me to start from scratch. No leads or anything?â
âYou know I wouldnât do that, son,â Fenton Hardy replied, smiling. âI have two possible leads.
âWhile I was in Washington, I called on an old friendâan Indian importer. I talked with him about the illegal entry of aliens from his country and told him I was going to ask you boys to work on the case. He naturally frowns on anything that will detract from his countryâs good reputation, and has offered to assist in every way he can.â
âDid he give you any leads?â Frank asked.
âNo, but I mentioned to him that there must be some means of communication between the smugglers and their confederates on shore. We eliminated radio and telegraph because they could be monitored. But it occurred to me that secret messages, instructing the contact here to pick up the smuggled men, might be sent by carrier pigeons from the ships offshore to the racketeersâ hideout on land. Ghapur agreed.â
âGhapur!â Joe burst out. âDad, is your Indian friendâs name Rahmud Ghapur?â
âWhy, yes, son,â Mr. Hardy answered.
The boys told their father about the falcon they had received from Ghapur, the attempted theft of the bird, and the ruby-bearing carrier pigeon which the peregrine had downed.
âThatâs very interesting,â Mr. Hardy said. âIâll phone Ghapur at once.â
Fortunately the importer was at home. The detective talked with him for some time, then returned to the table.
âMr. Ghapur says he sent the falcon to aid you boys in bringing down pigeons you might be suspicious of. He mailed a letter of explanation. Didnât it arrive?â
âNo,â Frank replied, adding thoughtfully, âThe letter could have been intercepted by the smugglers if they suspected what the falcon was to be used for.â
âTrue,â Mr. Hardy declared. âGhapur asked you boys to get in touch with a fellow countryman of his who lives here in Bayport. Heâs Ahmed, the rug dealer. You know him. Heâll teach you how to handle the falcon properly.â
This statement caused Aunt Gertrude to speak up sharply, deploring the fact that the boys were getting involved in such a cruel sport.
âAunty,â said Frank, âitâs in the line of duty. And anyway, wild hawks eat ten times as many pigeons and other birds in a year than weâd let a trained falcon like Miss Peregrine go after.â
âHumph !â Aunt Gertrude was unconvinced, and was about to continue her tirade when Mrs. Hardy arose and started clearing the table. Her husband and sons got up too and went to the garage to see the falcon. After examining her trappings, Mr. Hardy said with a smile:
âIt will be rather unique to solve a mystery with a hooded hawk.â
âYes,â agreed Frank. âDad, do you think there might be a tie-in between the smugglers of aliens and the rubies?â
âYes, I do,â Mr. Hardy replied. âAnd I have a hunch weâll find that carrier pigeons are the link between our two mysteries.â
They talked for a while longer, then Fenton Hardy concluded with, âWell, boys, it will have
