the scowling prisoner. They drove to headquarters. There the man gave his name as John Smith. He denied that he had ever gone under the name of Johnson, that he had ever been to the Phillips house, or that he had received any cartons.
He was booked on a charge of assault and battery. The express-company driver was sent for and identified him as the man who had signed for Aunt Gertrudeâs missing carton. The suspect said the expressman was crazy, and then maintained a stony silence.
A figure hurtled through the window
âAny identification on him?â Joe asked Riley after the man had been searched.
âNot a thing,â the policeman replied. âJust some figures scribbled on the back of an old envelope. Canât make head or tail of them.â Riley produced the evidence. Joe whooped. Scrawled on the paper were letters and numbers:
A23â151âC2âD576âA19395âM14
âThe same as those found at Mrs. Armstrongâs home!â Joe thought excitedly.
Written beneath the figures was Falcon.
âThe name of the phantom freighter!â Joe gasped.
âWhat?â Riley asked.
Joe quickly told him Captain Harknessâs story and the officer promised to investigate.
When Joe and Chet arrived at the Hardy home, they expected to find Frank there. But he had not yet come back.
âThatâs strange,â reflected Joe. âI wonder where he went.â
For the next few hours the family and Chet anxiously waited for news of Frank. With growing concern, Joe and Chet returned to the waterfront and searched the docks thoroughly, making scores of inquiries. But to no avail!
When they arrived home they found Mrs. Hardy, pale and tight-lipped, near the telephone. Her husband was away, and Aunt Gertrude paced up and down nervously. âThat man they have locked up in jailâIâll bet he knows what happened,â she declared. âIf I had my wayââ
âBut the police have questioned him a dozen times, Aunty,â said Joe. âHe wonât talk.â
âWhat time is it?â asked Mrs. Hardy.
âTwo oâclock in the morning, Mother,â Joe replied. âYouâd better go to bed and get some rest.â
âI wouldnât be able to sleep. If Frank doesnât show up by seven,â said Mrs. Hardy, âIâll have to telephone your father.â
âNo use bothering Fenton until weâre sure itâs serious,â said Aunt Gertrude. âFrank will turn up,â she added to calm Mrs. Hardy, but to herself she said, âIâm afraid something terrible has happened.â
The telephone jangled harshly. Mrs. Hardy sprang to her feet, but Joe reached the instrument ahead of her.
âIs this the home of Fenton Hardy?â demanded a rough voice.
âYes.â
âWho is this?â
âJoe Hardy.â
âAll right, kid. In case youâre worrying about your brother, hereâs a tip. Youâll find him on the porch of a summer bungalow about two miles up the Willow River. Better go and get him because heâs in no shape to walk home.â
âWhoâs speaking? What bungalow? Is he all right?â
The caller hung up.
âWhat is it, Joe?â Mrs. Hardy asked tensely, and he repeated the conversation.
The message had been ominous, but Joe tried to be cheerful. âOh, Iâm sure Frankâs all right. Come on, Chet. Weâll take the Sleuth and go out there.â
âIâm going with you,â Aunt Gertrude said brusquely. âCome on, Laura, you too!â
Joe looked up. âBetter not. What if itâs a trap?â
âA trap? But why?â
âMaybe someone wants to get us all out of the house, for some reason,â suggested Joe.
Mrs. Hardy was distressed. âThen maybe Frank wonât be there at all,â she said.
âOh, Iâm sure he is, Mother. But weâd better not take chances. Stay here and call Chief
