All
three were gazing intently and silently after the departing boys.
'I'm sure that those people know more about Dad's cap than they're telling,' Frank said grimly, as the
boys mounted their motorcycles and rode back toward Bayport.
'What are you planning to do next?' Phil asked as he pulled his machine alongside Frank's.
'I'm going right to Chief Collig and tell him the whole story.'
'Okay, we're with you!'
The boys rode directly to police headquarters and left their motorcycles in the parking lot. Chief Collig
looked up as his six visitors were ushered into his office.
'Well,' he said heartily, 'this is quite a delegation! What can I do for you?'
As Frank and Joe took turns, with an occasional graphic illustration from one of the other boys, they told
the full story and showed him the bloodstained cap.
Chief Collig looked grave. 'I don't like the sound of this at all,' he said finally. 'We must find your father
at once! This cap is a good clue.' Then he went on, 'Of course you realize that the area where the Pollitt
house is located is outside the limits of Bayport, so my men can't go there. But I'll get in touch with
Captain Ryder of the State Police at once, so he can assign men to the case.'
The boys thanked the chief for his help and left. Chet, Tony, Biff, and Phil went their separate ways while
Frank and Joe turned toward home. They decided not to upset their mother about the bloodstained cap,
but merely tell her that the State Police would take over the search for her husband.
'I still think there's some connection between Dad's disappearance and the smuggling outfit and the house
on the cliff,' Frank declared.
'What I've been wondering,' said Joe, 'is where those two motorboats came from that day Jones was
attacked. We didn't see them out in the ocean earlier-at least not both of them.'
'That's right. They could have come right out from under the cliff.'
'You mean, Frank, there might be a secret harbor in there?'
'Might be. Here's the way it could work. Dad suspects smugglers are operating in this territory from a
base that he has been unable to find.' Frank spread his arms. 'The base is the old Pollitt place! What
more do you want?'
'But the house is on top of a cliff.'
'There could be a secret passage from the house to a hidden harbor at the foot of the cliff.'
'Good night, Frank, it sure sounds reasonable!'
'And perhaps that explains why the kidnapers got away with Jones so quickly on Saturday. If they left
the Kane farmhouse just a little while before we did, we should have been able to get within sight of their
car. But we didn't.'
'You mean they turned in at the Pollitt place?'
'Why not? Probably Jones is hidden there right now.'
'And maybe Dad too,' Joe cried out excitedly.
'That's right. I'm against just sitting and waiting for the state troopers to find him. How about asking Tony
if he will lend us his motorboat, so we can investigate the foot of that cliff?'
'I get you!' Joe agreed enthusiastically. 'And if we pick up any information we can turn it over to the
State Police and they can raid the Pollitt place!'
CHAPTER X
A Watery Tunnel
WHEN the brothers arrived home Frank and Joe assured their mother that the State Police would soon
find Mr. Hardy. Some of the anxiety left her face as she listened to her sons' reassuring words.
When she went to the kitchen to start preparations for supper, the boys went to phone Tony Prito. After
Frank explained their plan to him, he agreed at once to let them use the Napoli, provided they took him
along.
'I wouldn't miss it for anything,' he said. 'But I can't go until afternoon. Have to do some work for my
dad in the morning. I'll meet you at the boathouse at two o'clock.'
'Swell, Tony. I have a job of my own in the morning.'
Chet called a few minutes later. As Frank finished telling him about the plan, he whistled.
'You fellows have got your nerve all right. But count me in, will you? I started this thing with you and I'd
like to finish it. We've got to find your father!'
After Chet had said good-by, Joe asked his brother, 'What's on for the morning?'
'I want to go down to the waterfront and talk to Pretzel Pete again. He might have another clue. Also, I
want to find out when the Marco Polo is due back here.'
Joe nodded. 'I get it. You think something may be going on then?'
'Right. And if we can find Dad and lead the Coast Guard to the smugglers before the boat docks-'
'Brother, that's a big order.'
By nine o'clock the following morning Frank and Joe were down at the Bayport docks. Pretzel Pete was
not in evidence.
'We'd better be cagey about asking when the Marco Polo's coming in,' Frank cautioned. 'The smugglers
probably have spies around here and we'd sure be targets.'
Acting as if there were no problems on their minds, Frank and Joe strolled along whistling. Once they
joined a group of people who were watching a sidewalk merchant. The man was demonstrating little
jumping animals. Frank and Joe laughed as they bought a monkey and a kangaroo. 'Iola and Callie will
get a kick out of these,' Joe predicted.
'Say, Frank, here comes Pretzel Pete now!' Joe whispered.
The Hardys went up the street, saying in a loud voice in case anyone was listening, that they were hungry
and glad to see Pete.
'Nobody can make pretzels like yours,' Joe exclaimed. 'Give me a dozen. Two for my mouth and ten for
my pockets.'
As Pretzel Pete laughed and pulled out a cellophane bag to fill the order, Frank said in a whisper, 'Heard
anything new?'
'Not a thing, son.' Pete could talk without moving his lips. 'But I may know something tomorrow.'
'How come?'
'The Marco Polo's docking real early-five A.M. I heard Ali Singh is one of the crew. I'll try to get a line
on him.'
'Great! We'll be seeing you.'
The boys moved off, and to avoid arousing any suspicion as to why they were in the area, headed for a
famous fish market.
'Mother will be surprised to see our morning's catch,' Joe said with a grin as he picked out a large
bluefish.
The brothers did not discuss the exciting information Pretzel Pete had given them until they were in the
safety of their own home. Then Joe burst out, 'Frank, if the Marco Polo gets offshore during the night, it'll
have to lay outside until it's time to dock!'
'And that'll give those smugglers a real break in picking up the stolen drugs!' Frank added. 'Maybe we
should pass along our suspicions to the Coast Guard.'
'Not yet,' Joe objected. 'All we have to go on is Pretzel Pete's statements about Ali Singh. Maybe we'll
learn more this afternoon and then we can report it.'
