Night Probe!

The Washington athletic community looked askance at Sandecker's running habits. He was the only jogger anyone had ever seen pounding along the sidewalk with an ever-present Churchill-style cigar stub protruding from his mouth.
He was puffing along toward the NUMA building under an early morning overcast sky when a rotund man in a rumpled suit, sitting on a bus bench, looked up over a newspaper.
"Admiral Sandecker, may I have a word with you?"
Sandecker turned out of curiosity, but not recognizing the President's security adviser, he kept his stride. "Call me for an appointment," he panted indifferently. "I don't like to break my pace."
"Please, Admiral, I'm Alan Mercier."
Sandecker stopped, his eyes narrowing. "Mercier?"
Mercier folded the newspaper and stood. "My apologies for interrupting your morning exercise, but I understand you're a hard man to trap for conversation."
"Your office supersedes mine. You could have simply ordered me to come to the White House."
"I'm not fanatical on official protocol," Mercier replied. "An informal meeting such as this has its advantages."
"Like catching your quarry off his home ground," said Sandecker, cannily sizing up Mercier. "A sneaky tactic. I use it myself on occasion."
"According to rumors, you're a master of sneaky tactics."
Sandecker's expression went blank for an instant. Then he burst into a laugh, pulled a lighter from a pocket of his sweat suit and lit the cigar stub. "I know when I'm licked. You didn't ambush me for my wallet, Mr. Mercier. What's on your mind?"
"Very well, suppose you tell me about the doodlebug."
"Doodlebug?" The admiral gave a faint tilt to his head-a movement equivalent to stunned surprise in any other man. "A fascinating instrument. I assume you're familiar with its purpose."
"Why don't you tell me?"
Sandecker shrugged. "I guess you could say it's a kind of water dowser."
"Water dowsers don't cost six hundred and eighty million taxpayer dollars."
"What exactly do you want to know?"
"Does such an exotic instrument exist?"
"The Doodlebug Project is a reality, and a damned successful one, I might add."
"Are you prepared to explain its operation and account for the money spent on its development?"
"When?"
"At the earliest opportunity."
"Give me two weeks and I'll lay the doodlebug in your lap neatly wrapped and packaged."
Mercier was not to be taken in. "Two days."
"I know what you're thinking," said Sandecker earnestly. "But I promise you there is no fear of scandal, far from it. Trust me for at least a week. I simply can't put it together in less."
"I'm beginning to feel like an accomplice in a con game."
"Please, one week."
Mercier looked into Sandecker's eyes. My God, he thought, the man is actually begging. It was hardly what he expected. He motioned to his driver who was parked a short distance away and nodded. "Okay, Admiral, you've got your week."
"You drive a tough bargain," said Sandecker, with a sly grin.
Without another word the admiral turned and resumed his morning jog to NUMA headquarters.
Mercier watched the little man grow even smaller in the distance. He seemed not to notice his driver standing patiently beside the car, holding the door open.
Mercier stood rooted, a maddening certainty growing within him that he'd been had.
It had been an exhausting day for Sandecker. After his unexpected meeting with Mercier he fenced with a congressional budget committee until eight in the evening, hawking the goals and accomplishments of NUMA, appealing for, and in a few cases, demanding additional funding for his agency's operations. It was a bureaucratic chore he detested.
After a light dinner at the Army and Navy Club, he entered his apartment at the Watergate and poured himself a glass of buttermilk.
He took off his shoes and was beginning to unwind when the phone rang. He would have ignored it if he hadn't turned to see which line held the incoming call. The red light on the direct circuit to NUMA blinked ominously. "Sandecker."
"Ramon King here, Admiral. We've got a problem on the Doodlebug."
"A malfunction?"
"No such luck," replied King. "Our sweep systems have picked up an intruder."
"Is he closing with our vessel?"
"Negative."
"A chance passing by one of our own subs then," Sandecker suggested optimistically.
King sounded concerned. "The contact is maintaining a parallel course, distance four thousand meters. It appears to be shadowing the Doodlebug.
"Not good."
"I'll have a firmer grasp on the situation when the computers spit out a more detailed analysis of our unknown caller."
Sandecker went silent. He sipped at the buttermilk, his mind meditative. Finally, he said, "Call the security desk and tell them to track down Al Giordino. I want him in on this."
King spoke hesitantly. "Is Giordino acquainted with…... ah, does he…...?"
"He knows," Sandecker assured King. "I personally briefed him on the project during its inception in the event he had to substitute for Pitt. You'd better get on with it. I'll be there in fifteen minutes."
The admiral hung up. His worst fear had put in its appearance. He stared at the white liquid within the glass as if he could visualize the mysterious craft stalking the defenseless Doodlebug.
Then he set the glass aside and hurried out the door, unaware that he was still in his stocking feet.
Deep beneath the surface of the Labrador Sea not far from the northern tip of Newfoundland, Pitt stood in stony silence, studying the electronic readout across the display screen as the unidentified submarine skirted the outer fringes of the Doodlebug's instrument range. He leaned forward as a line of data flashed on. Then, suddenly, the display screen blinked out as contact was lost.
Bill Lasky, the panel operator, turned to Pitt and shook his head. "Sorry, Dirk, our visitor is a shy one. He won't sit still for a scan."
Pitt put his hand on Lasky's shoulder. "Keep trying. Sooner or later he's bound to step on our side of the fence."
He moved across the control room through the maze of complex electronic gear, his feet silent on the rubber deck covering. Dropping down a ladder to a lower deck, he entered a small room not much bigger than a pair of adjoining phone booths.
Pitt sat on the edge of a folding bunk, spread a blueprint on a small writing desk and studied the guts of the Doodlebug.
A diving deformity was the less than endearing term that ran through his mind when he first laid eyes on the world's most sophisticated research vessel. It looked like nothing previously built to prowl beneath the seas.
The Doodlebug's compact form lay somewhere south of ludicrous. The best descriptions anybody had come up with were "the inner half of an aircraft wing standing on end" and "the conning tower of a submarine that has lost its hull." In short, it was a slab of metal that traveled in a vertical position.
There was a reason for the unorthodox lines of the Doodlebug. The concept was a considerable leap in submersible technology. In the past, all mechanical and electronic systems had been built to conform within the space limitations of a standard cigar-shaped hull. The Doodlebug's aluminum shell, on the other hand, had been built around its instrument package.
