hopefully, as they drove downtown to headquarters.
But when they arrived, the lieutenant greeted Chief Collig with the news that there were no fingerprints matching Kellyâs in the police file. A quick teletype check with the FBI, using the Henry system, had also been fruitless.
âA blank wall, all right,â Joe observed in disgust. âBut he sure looks guilty.â
âWeâll keep on the alert for other clues,â Frank declared.
Chief Collig promised that he in turn would circulate a description of Kelly and let the boys know if he learned anything. They said good-by and were driven home by a patrolman.
The brothers found their petite, pretty mother and their Aunt Gertrude waiting for them in the living room. The women looked worried.
âI hate to see you two get mixed up in another dangerous mysteryâand your father is still out on his case.â Mrs. Hardy sighed.
âYes,â sniffed Aunt Gertrude. âI just know youâll be hurt one of these days.â
Frank and Joe gave both women a hug, and Joe said, âWeâre still alive and able to eat.â He grinned and added, âYou know we can take care of ourselves.â
It was true. The boys had been involved in many risky adventures since their first caseâThe Tower Treasure. Recently they had challenged a ruthless band of hijackers while tracking down The Clue of the Screeching Owl.
Despite the womenâs concern for the boysâ safety, they obviously were interested as the brothers told of their visit to the hospital. They, too, thought it was significant that there was nothing on the injured man giving an address When Frank mentioned that the manâs worn clothing did not fit him, Aunt Gertrude looked thoughtful.
âThere was a man at our guild sale today who bought some used clothing!â she exclaimed. âHe didnât seem like the type we usually have as a customer.â
Joe broke in eagerly, âCan you describe him, Aunt Gertrude?â
âI remember him clearly. He was very pale and thin. Acted sort of furtiveâheâd look away whenever anyone caught his eye. He was well dressed in a black-and-white checkered sport jacket and gray slacks, but the clothes he bought were almost threadbare. I was sure theyâd be too big.â
Frank burst out, âThat could have been Kelly. Heâs pale and thin. His clothes were worn and certainly didnât fit him!â
âSure!â Joe put in excitedly. âA rummage sale would be the perfect place to buy used clothing if someone wanted to make sure it wouldnât be traced.â
âIf we could find his regular clothes,â said Frank, âmaybe weâd learn where Kelly comes from.â
âYou can look for that evidence in the morning,â their mother announced quietly. âIt is late.â
Admitting that it had been a long day, the brothers said good night and went to bed. They were sound asleep almost instantly.
At breakfast the next morning Frank and Joe briefed their father on the hospital trip and their suspicions of Kelly. The detective frowned. âIâd certainly like to find out,â he said, âwhat the fellow is up to.â
Just then a cheerful whistle sounded from the front lawn, and a moment later Biff Hooper and Tony Prito appeared in the hall.
âWeâre all set,â cried Biff. He waved two plane tickets for that afternoonâs flight to Alberta.
âAt Edmonton, the capital of the province,â Biff explained, âweâll change for Hay River. There weâll pick up a plane going across Great Slave Lake to Yellowknife.â
âThatâs where Sam Radley will meet us. Right, Mr. Hardy?â Tony asked.
âYes. Iâll telegraph Sam your schedule,â the detective replied. âHeâll give you the necessary orders when you arrive.â
âGreat!â Tony grinned, and Biff added, âWeâll do our best
