woodland to one side of it. Good place to hide a stolen car."
Mr. Hardy suggested that the boys meet for a picnic lunch at Willow Grove
and later do some sleuthing in the vicinity. "That is, provided you haven't
found Chet's jalopy by that time."
Mrs. Hardy spoke up. "I'll fix a nice lunch for all of you," she offered.
"That sure would be swell," Chet said hastily. "You make grand picnic
lunches, Mrs. Hardy."
Frank and Joe liked the plan, and it was decided that the boys would have the
picnic whether or not they had found the jalopy by one o'clock. Mrs. Hardy
said she would relay the news to the other boys when they phoned in.
Chet and Joe set off on the Hardy boys' motorcycles, taking the
twelve-to-three segment on the map. Then Mr. Hardy and Frank drove off for
the three-to-six area.
Hour after hour went by, with the searchers constantly on the alert. Every
garage, public and private, every little-used road, every patch of woods was
thoroughly investigated. There was no sign of Chet's missing yellow jalopy.
Finally at one o'clock Frank and his father returned to the Hardy home. A
few moments later Joe and Chet returned and a huge picnic lunch was
stowed aboard the two motorcycles.
When the three boys reached the picnic area they were required to park their
motorcycles outside the fence. They unstrapped the lunch baskets and carried
them down to the lake front The other boys were already there.
"Too bad we can't go swimming," Tony remarked, "but this water's pretty
cold."
Quickly they unpacked the food and assembled around one of the park picnic
tables.
"Um! Yum! Chicken sandwiches!" Chet cried gleefully.
During the meal the boys exchanged reports on their morning's sleuthing. All
had tried hard but failed to find any trace of the missing car.
"Our work hasn't ended," Frank reminded the others. "But I'm so stuffed
I'm going to rest a while before I start out again."
All the other boys but Joe Hardy felt the same way and lay down on the grass
for a nap. Joe, eager to find out whether or not the woods to their right held
the secret of the missing car, plunged off alone through the underbrush.
He searched for twenty minutes without finding a clue to any automobile. He
was on the point of returning and waiting for the other boys when he saw a
small clearing ahead of him. It appeared to be part of an abandoned
roadway.
Excitedly Joe pushed on through the dense undergrowth. It was in a low-lying
part of the grove and the ground was wet. At one point it was quite muddy,
and it was here that Joe saw something that aroused his curiosity.
"A tire! Then maybe an automobile has been in here," he muttered to himself,
although there were no tire marks in the immediate vicinity. "No footprints,
either. I guess someone tossed this tire here."
Remembering his father's admonitions on the value of developing one's
powers of observation, Joe went closer and examined the tire.
"That tread," he thought excitedly, "looks familiar."
He gazed at it until he was sure, then dashed back to the other boys.
"I've found a clue!" he cried out. "Come on, everybody!"
CHAPTER VI
The Robbery
JOE HARDY quickly led the way into the swampy area as the other boys
trooped along, everyone talking at once. When they reached the spot, Chet
examined the tire and exclaimed:
"There's no mistake about it! This is one of the tires! When the thief put on
the new one, he threw this away."
"Perhaps the Queen is still around," suggested Frank quickly. "The thief
may have picked this road as a good place to hide your jalopy until he could
make a getaway."
"It would be an ideal place," Chet agreed. "People coming to Willow Grove
have to park at the gate, so nobody would come in here. But this old road
comes in from the main highway. Let's take a look, fellows."
A scrutinizing search was begun along the abandoned road in the direction of
the highway. A moment later Frank and Chet, in the lead, cried out
simultaneously.
"Here's a bypath! And here are tire marks!" Frank exclaimed. To one side
was a narrow roadway, almost overgrown with weeds and low bushes. It led
from the abandoned road into the depths of the woods.
widened out, then wound about a heavy clump of trees. It came to an end in a
wide clearing.
In the clearing stood Chet Morton's lost jalopy!
"My Queen!" he yelled in delight. "Her own license plates!"
His shout was heard by the rest of the boys, who came on a run. Chet's joy
was boundless. He examined the car with minute care, while his chums
crowded around. At last he straightened up with a smile of satisfaction.
"She hasn't been damaged a bit. All ready to run. The thief just hid the old
bus in here and made a getaway. Come on, fellows, climb aboard. Free ride
to the highway!"
Before leaving, the Hardys examined footprints left by the thief. "He wore
sneakers," Frank observed.
Suddenly Chet swung open the door and looked on the floor. "You mean he
wore my sneakers. They're gone."
"And carried his own shoes," Joe observed. "Very clever. Well, that washes
out one clue. Can't trace the man by his shoe prints."
"Let's go!" Chet urged.
He jumped into the car and in a few seconds the engine roared. There was
barely sufficient room in the clearing to permit him to turn the jalopy about.
When he swung around and headed up the bypath, the boys gave a cheer and
hastened to clamber aboard.
Lurching and swaying, the car reached the abandoned road and from there
made the run to the main highway. The boys transferred to Tony's truck and
the motorcycles, and formed a parade into Bayport, with Frank and Joe in
the lead. It was their intention to ride up to police headquarters and announce
their success to Chief Collig.
"And I hope Smuff will be around," Chet gloated.
As the grinning riders came down Main Street, however, they noticed that no
one paid any attention to them, and there seemed to be an unusual air of
mystery in the town. People were standing in little groups, gesticulating and
talking earnestly.
Presently the Hardys saw Oscar Smuff striding along with a portentous
frown. Joe called out to him. "What's going on, detective? You notice we
found Chet's car."
"I've got something more important than stolen cars to worry-Hey, what's
that?" Detective Smuff stared blankly, as the full import of the discovery
filtered his consciousness.
The boys waited for Smuff's praise, but he did not give it. Instead, he said, "I
got a big mystery to solve. The Tower Mansion has been robbed!"
"Good night!" the Hardys chorused.
Tower Mansion was one of the show places of Bayport. Few people in the
city had ever been permitted to enter the place and the admiration which the
palatial building excited was solely by reason of its exterior appearance. But
the first thing a newcomer to Bayport usually asked was, "Who owns tha
t
house with the towers over on the hill?"
It was an immense, rambling stone structure overlooking the bay, and could
be seen for miles, silhouetted against the sky line like an ancient feudal castle.
The resemblance to a castle was heightened by the fact that from each of the
far ends of the mansion arose a high tower.
One of these had been built when the mansion was erected by Major
Applegate, an eccentric, retired old Army man who had made a fortune by
lucky real-estate deals. Years ago there had been many parties and dances in
the mansion.
But the Applegate family had become scattered until at last there remained in
the old home only Hurd Applegate and his sister Adelia. They lived in the
vast, lonely mansion at the present time.
Hurd Applegate was a man about sixty, tall, and stooped. His life seemed to
be devoted now to the collection of rare stamps. But a few years before he
had built a new tower on the mansion, a duplicate of the original one.
His sister Adelia was a maiden lady of uncertain years. Well-dressed women
in Bayport were amused by her clothes. She dressed in clashing colors and
unbecoming styles. Hurd and Adelia Applegate were reputed to be
enormously wealthy, although they lived simply, kept only a few servants, and
never had visitors.
"Tell us about the theft," Joe begged Smuff.
But the detective waved his hand airily. "You'll have to find out yourselves,"
he retorted as he hurried off.
Frank and Joe called good-by to their friends and headed for home. As they
arrived, the boys saw Hurd Applegate just leaving the house. The man tapped
the steps with his cane as he came down them. When he heard the boys'
motorcycles he gave them a piercing glance.
"Good day!" he growled in a grudging manner and went on his way.
"He must have been asking Dad to take the case," Frank said to his brother,
as they pulled into the garage.
The boys rushed into the house, eager to find out more about the robbery. In
the front hallway they met their father.
"We heard the Tower Mansion has been robbed," said Joe.
Mr. Hardy nodded. "Yes. Mr. Applegate was just here to tell me about it. He
wants me to handle the case."
"How much was taken?"
Mr. Hardy smiled. "Well, I don't suppose it will do any harm to tell you. The
safe in the Applegate library was opened. The loss will be about forty
thousand dollars, all in securities and jewels."
"Whew!" exclaimed Frank. "What a haul! When did it happen?"
"Either last night or this morning. Mr. Apple-gate did not get up until after
ten o'clock this morning and did not go into the library until nearly noon. It
was then that he discovered the theft."
"How was the safe opened?"
"By using the combination. It was opened either by someone who knew the
set of numbers or else by a very clever thief who could detect the noise of the
tumblers. I'm going up to the house in a few minutes. Mr. Applegate is to call
for me."
"I'd like to go along," Joe said eagerly.
"So would I," Frank declared.
Mr. Hardy looked at his sons and smiled. "Well, if you want to be detectives,
I suppose it is about as good a chance as any to watch a crime investigation
from the inside. If Mr. Applegate doesn't object, you may come with me."
A few minutes later a foreign-make, chauffeur-driven car drew up before the
Hardy home. Mr.
Applegate was seated in the rear, his chin resting on his cane. The three
Hardys went outside. When the detective mentioned the boys' request, the
man merely grunted assent and moved over. Frank and Joe stepped in after
their father. The car headed toward Tower Mansion.
"I don't really need a detective in this case!" Hurd Applegate snapped.
"Don't need one at all. It's as clear as the nose on your face. I know who
took the stuff. But I can't prove it."
"Whom do you suspect?" Fenton Hardy asked.
"Only one man in the world could have taken the jewels and securities.
Robinson!"
"Robinson?"
"Yes. Henry Robinson-the caretaker. He's the man."
The Hardy boys looked at each other in consternation. Henry Robinson, the
caretaker of the Tower Mansion, was the father of one of their closest
chums! Perry Robinson, nicknamed "Slim," was the son of the accused man!
That his father should be blamed for the robbery seemed absurd to the Hardy
boys. They had met Mr. Robinson upon several occasions and he had
appeared to be a good-natured, easygoing man with high principles.
"I don't believe he's guilty," Frank whispered.
"Neither do I," returned his brother.
"What makes you suspect Robinson?" Mr. Hardy asked Hurd Applegate.
"He's the only person besides my sister and me who ever saw that safe
opened and closed. He could have learned the combination if he'd kept his
eyes and ears open, which I'm sure he did."
"Is that your only reason for suspecting him?"
"No. This morning he paid off a nine-hundred-dollar note at the bank. And I
know for a fact he didn't have more than one hundred dollars to his name a
few days ago. Now where did he raise nine hundred dollars so suddenly?"
"Perhaps he has a good explanation," Mr. Hardy suggested.
"Oh, he'll have an explanation all right!" sniffed Mr. Applegate. "But it will
have to be a mighty good one to satisfy me."
The automobile was now speeding up the wide driveway that led to Tower
Mansion and within a few minutes stopped at the front entrance. Mr. Hardy
and the two boys accompanied the eccentric man into the house.
"Nothing has been disturbed in the library since the discovery of the theft,"
he said, leading the way there.
Mr. Hardy examined the open safe, then took a special magnifying glass from
his pocket. With minute care he inspected the dial of the combination lock.
Next he walked to each window and the door to examine them for
fingerprints. He asked Mr. Applegate to hold his fingers up to a strong light
and got a clear view of the whorls and lines
on the inside of the tips. At last he shook his head.
"A smooth job," he observed. "The thief must have worn gloves. All the
fingerprints in the room, Mr. Applegate, seem to be yours."
"No use looking for fingerprints or any other evidence!" Mr. Applegate
barked impatiently. "It was Robinson, I tell you."
"Perhaps it would be a good idea for me to ask him a few questions," Mr.
Hardy advised.
Mr. Applegate rang for one of the servants and instructed him to tell the
caretaker to come to the library at once. Mr. Hardy glanced at the boys and
suggested they wait in the hallway.
"It might prove less embarrassing to Mr. Robinson that way," he said in a
low voice.
Frank and Joe readily withdrew. In the hall they met Mr. Robinson and his
son Perry. The man was calm, but pale, and at the doorway he patted Slim on
the shoulder.
"Don't worry," he said. "Everything will be all right." With that he entered
the library.
Slim turned to his two friends. "It's got to be!" he cried out. "My dad is
innocent!"
CHAPTER VII
The Arrest
FRANK and Joe were determined to help their chum prove his father's
innocence. They shared his conviction that Mr. Robinson was not guilty.
"Of course he's innocent," Frank agreed. "He'll be able to clear himself all
right, Slim."
"But things look pretty black right now," the boy said. He was white-faced
and shaken. "Unless Mr. Hardy can catch the real thief, I'm afraid Dad will
be blamed for the robbery."
"Everybody knows your father is honest," said Joe consolingly. "He has
been a faithful employee -even Mr. Applegate will have to admit that."
"Which won't help him much if he can't clear himself of the charge. And Dad
admits that he did know the combination of the safe, although of course he'd
never use it."
"He knew it?" repeated Joe, surprised.
"Dad learned the combination accidentally. It was so simple one couldn't
forget it. This was how it happened. One day when he was cleaning the
library fireplace, he found a piece of paper with numbers on it. He studied
them and decided they were the safe combination. Dad laid the paper on the
desk. The window was open and he figured the breeze must have blown the
paper to the floor."
"Does Mr. Applegate know that?"
"Not yet. But Dad is going to tell him now. He realizes it will look bad for
him, but he's going to give Mr. Applegate the truth."
From the library came the hum of voices. The harsh tones of Hurd Applegate
occasionally rose above the murmur of conversation and finally the boys
heard Mr. Robinson's voice rise sharply.
"I didn't do it! I tell you I didn't take that money!"
"Then where did you get the nine hundred you paid on that note?" demanded
Mr. Applegate.
Silence.
"Where did you get it?"
"I'm not at liberty to tell you or anyone else."
"Why not?"
"I got the money honestly-that's all I can say about it."
"Oh, ho!" exclaimed Mr. Applegate. "You got the money honestly, yet you
can't tell me where it came from! A pretty story! If you got the money
honestly you shouldn't be ashamed to tell where it came from."
"I'm not ashamed. I can only say again, I'm not at liberty to talk about it."
"Mighty funny thing that you should get nine hundred dollars so quickly. You
were pretty hard up last week, weren't you? Had to ask for an advance on
