latest newspapers and magazines. Two portraits hung on the opposite wall, flanking the entrance to the main dining room.
âI wonder who those old geezers are,â Chet whispered to Joe.
The younger Hardy walked closer, surveyed the inscriptions under the portraits, and came back. âTheyâre two presidents of the United States,â he said. âWoodrow Wilson and Grover Cleveland.â
Frank strode out of the office and announced that they were set for the night. The three drove to the rear of the club and left the car in the parking lot. Walking toward the back door, they examined the building, which had plenty of corners and angles, tilting roofs and high eaves.
âThe club would make a good haunted house,â Joe suggested. âAll we need is a spooky face at the window. Frank! There he is!â
âWho?â Frank asked, glancing in the direction his brother had indicated.
âThe guy from the lab!â Joe gasped. âHe was right there, looking out that window. The fellow with the tinted glasses!â
âI donât see him now,â Frank stated, âbut letâs go inside and see if we can catch him!â
The boys hurried up the wooden steps and through the coatroom door. Seeing nobody, they hastened down the hallway into the reading room, through the dining room, and to the front door.
A footfall on the carpet made them whirl. Their shadow was trying to tiptoe down the stairs to the basement!
The boys rushed after him. As they reached the bottom of the stairs, they saw him run into the bar. By the time they got there, he was exiting by another door.
The pursuers went pell-mell up the stairs to the first floor, and then to the second floor, where Chet was too exhausted to go any farther. He sat on the top step and watched the Hardys race along the corridor to where the man was climbing out the window. The fugitive slid down the fire escape to an alley at the bottom, and hurried around the corner into Nassau Street.
When Frank and Joe reached the spot, the man had vanished!
CHAPTER V
Night Visitor
âNo SIGN of him,â Joe said, looking up and down the street. âHe could be anywhere by now.â
Frank nodded glumly. âYouâre right. We lost him.â
The boys returned to the club and picked up Chet, then went to their room. It overlooked the alley and had a fire escape under the window.
âGood,â Chet declared when he noticed the exit. âWe can get out of here in a hurry if weâre cornered by crooks. Say, how about chow? I havenât eaten since breakfast. I might faint.â
âIf you do, youâll shake up the club,â Joe quipped. âIt wasnât built for your weight.â
Chet looked pained, but Frank came to his rescue. âIâm with you, Chet. Itâs dinnertime anyway.â
The boys freshened up a bit, then went to the dining room. After giving the waiter their order, Chet leaned back in his chair. âWell, Hardys,â he grinned, âdo you have a plan for solving the big mystery yet?â
âWeâre working on it,â Joe said, sipping water from his glass.
âI think Jenson was kidnapped by a foreign power,â Chet declared.
âMaybe he worked for a foreign power and left on his own,â Joe put in.
âYou mean as a spy?â Chet asked.
Joe nodded. âPerhaps he developed the Firebird Rocket and sold the secret to someone else.â
Frank shook his head. âBut why would he wait until the United States finished building the missile ? I think he would have given away the secret earlier and stolen the plans in order to prevent us from completing the project.â
Chet nodded. âIâm with Frank. The spy angle doesnât seem to fit in this case. Jenson was probably kidnapped.â
âSo where do we start with our work?â Joe wanted to know.
âWe interview all the people at the lab,â Frank said. âLetâs
