Quickly Frank explained to him that their father seemed to be missing. "We thought you might have heard
this."
"Yes, I did," Pretzel Pete answered. "But I didn't think nothing about it. I always thought detectives
disappeared-sometimes in order to fool people they were after."
"They sometimes do," Joe told him. "But this time seems to be different. Dad said he often came down
here to get information from you-because you always give him good tips-and we wondered if you had
seen him lately."
"Yes."
"When?"
"Monday morning."
"Dad has been gone ever since."
"Hmm." The man frowned, picked up a pretzel from one of the aerials, and began to munch on it. "Help
yourselves, fellows."
Frank and Joe each took one of the pretzels.
They had just bitten into the delicious salted rings when Pete continued, "Now you got me worried. Your
pop's a fine man and I wouldn't want to see anything happen to him. I'll tell you a place you might look
for him."
Pretzel Pete said that he had picked up a bit of information that led him to think an East Indian sailor
named Ali Singh might be engaged in some smuggling. The vendor did not know what ship he sailed on,
but he understood that the man had come ashore for a secret meeting of some gang.
"This here meeting," Pretzel Pete explained, "was being held out in the country somewhere off the shore
road. It was to be in a deserted farmhouse on Hillcrest something or other. I don't remember whether it
was 'road' or 'street' or what."
"Was this last Monday?" Frank asked eagerly.
"Oh, no," the vendor answered. "This was about three weeks ago, but when I told your pop he seemed
real interested and said he guessed he'd go out there and look around."
Joe broke in, "Dad must have thought the rest of the gang might be living there. Maybe they're holding
him a prisoner!"
"Oh, I hope not," Pretzel Pete said worriedly. "But you fellows had better get right out there and take a
look."
"We certainly will," Frank told the man.
The brothers thanked Pretzel Pete for the information, then hurried home. Mrs. Hardy was not there, so
they did not have a chance to tell her about their plans.
"We'll leave a note," Frank decided and quickly wrote one.
Their hopes high, the brothers set off on their motorcycles on the search for their father. By now they
were very familiar with the shore road but did not recall having seen any sign reading Hillcrest.
"Suppose it's not marked," said Joe. "We'll never find it."
Frank gripped his handle bars hard. "If Dad found it, we won't give up until we do."
The motorcycles chugged past side road after side road. The farther away from Bayport the boys went,
the farther apart these roads became.
After a while they came to the Kanes' farmhouse and were tempted to stop to see if they might know
where Hillcrest was. But just then, a short distance ahead, Joe saw a small car suddenly turn into the
shore road. It seemed to have come right out of a clump of bushes and trees.
"Come on, Frank! Let's investigate that place."
The boys pushed ahead, hoping to speak to the driver of the car. But he shot down die road in the
opposite direction at terrific speed. When Frank and Joe reached the place from which he had just
emerged, they saw that it was a road, though hardly noticeable to anyone passing by.
"I'll take a look and see where it goes," Frank said, shutting off his motorcycle and walking up the grassy,
rutted lane. Suddenly he called back, "We're in luck, Joe. I see a homemade sign on a tree. It says
Hillcrest Road."
Frank returned to his brother and the boys trundled their machines up among the trees to hide them. Then
they set off afoot along the almost impassable woods road.
"There aren't any tire tracks," Joe remarked. "I guess that fellow who drove out of here must have left his
car down at the entrance."
Frank nodded, and then in a low tone suggested that they approach the deserted farmhouse very quietly,
in case members of the gang were there.
"In fact, I think it might be better if we didn't stay on this road but went through the woods."
Joe agreed and silently the Hardys picked-their way along among the trees and through the undergrowth.
Five minutes later they came to a clearing in which stood a ramshackle farmhouse. It looked as if it had
been abandoned for many years.
The young sleuths stood motionless, observing the run-down building intently. There was not a sound of
activity either inside or outside the place. After the boys had waited several minutes, Frank decided to
find out whether or not anyone was around. Picking up a large stone, he heaved it with precision aim at
the front door. It struck with a resounding thud and dropped to the floor of the sagging porch.
Frank's action brought no response and finally he said to Joe, "I guess nobody's home. Let's look in."
"Right," Joe agreed. "And if Dad's a prisoner there, we'll rescue him!"
The boys walked across the clearing. There was no lock on the door, so they opened it and went inside.
The place consisted of only four first-floor rooms. All were empty. A tiny cellar and a loft with a trap
door reached by a ladder also proved to have no one in them.
"I don't know whether to be glad or sorry Dad's not here," said Frank. "It could mean he escaped from
the gang if he was caught by them and is safely in hiding, but can't send any word to us."
"Or it could mean he's still a captive somewhere else," Joe said. "Let's look around here for dues."
The boys made a systematic search of the place. They found only one item which might prove to be
helpful. It was a torn piece of a turkish towel on which the word Polo appeared.
"This could have come from some country club where they play polo," Frank figured.
"Or some stable where polo ponies are kept," Joe suggested.
Puzzled, Frank put the scrap in his pocket and the brothers walked down Hillcrest Road. They brought
their motorcycles from behind the trees and climbed aboard.
"What do you think we should do next?" Joe asked.
"See Police Chief Collig in Bayport," Frank replied. "I think we should show him this towel Maybe he
can identify it."
Half an hour later they were seated in the chief's office. The tall, burly man took a great interest in the
Hardy boys and often worked with Fenton Hardy on his cases. Now Chief Collig gazed at the scrap of
toweling for a full minute, then slapped his desk.
"I have it!" he exclaimed. "That's a piece of towel from the Marco Polo!"
"What's that?"
"A passenger ship that ties up here once in a while."
Frank and Joe actually jumped in their chairs. Their thoughts went racing to Ali Singh, smugglers, a gang
at the deserted farmhouse I
At that moment Chief Collig's phone rang. The Hardys waited politely as he answered, hoping to discuss
these new developments with him. But suddenly he put down the instrument, jumped up, and said:
"Emergency, fellows. Have to leave right away!" With that he rushed out of his office.
Frank and Joe arose and disappointedly left headquarters. Returning home, they reported everything to
their mother, but upon seeing how forlorn she looked, Frank said hopefully, "That note you received with
Dad's name on it could have been on the level."
Mrs. Hardy shook her head. "Fenton wouldn't forget the secret sign. I just know he wouldn't"
Word quickly spread through Bayport that the famous Fenton Hardy had disappeared. Early the next
