"He"s likely to be somewhere in Radford, anyway," nodded young Benson.
"Wherever the fellow is found, he must be seized at once," continued Major Woodruff, warmly. "Any policeman will seize him on your request.
I will give each of you three a written statement that you have been asked to locate Millard and have him arrested. If you run across Millard anywhere, turn him over to a policeman, then show my written authorization. On that the police authorities will hold the scoundrel and notify the military authorities. Then, once we have Millard out at Fort Craven, securely under lock and key, by authority from Washington, we will make every effort under the sun to locate his charts and notebooks."
"Why, the work you want us to do is going to be easy enough," murmured Captain Jack.
"It is going to be easy, if you succeed in finding the fellow, and in turning him over to a policeman," replied Major Woodruff. "And, by the way, I have just remembered that Lieutenant Ridder, of the engineer corps, reported last night from a former station in the West. No one around here will know him. Good enough! I"ll have Ridder get into citizen"s clothes and go about with you three. He can give you instructions on any point about which you"re in doubt."
"We ought to run that rascal down, sir," answered Jack Benson, rising.
"Unless--"
"Unless what, Benson?"
"Why, sir, unless he"s more clever than a rascal usually succeeds in being. I haven"t lived so very long, Major Woodruff, but, from what little I"ve seen of the world, it has struck me that the cleverest scoundrels are always just a little less smart, in the end, than the average of honest men."
"I hope you"ll prove it, in this case," replied the major. "And now, to signal your boat. We"ll run both craft in at the ordnance dock at Fort Craven."
A couple of miles away Eph Somers was slowly running the submarine back and forth over the water in seeming aimlessness. In response to sharp blasts from the whistle of the Army tug, the "Spitfire" was seen to turn and head for the tug.
"Mr. Somers, you will follow in our wake," shouted Major Woodruff, when the two craft were within hailing distance of each other. "We will show you where to make fast at the ordnance dock."
"Very good, sir," Eph responded, with a salute.
A little later in the forenoon both boats docked at the water front of Fort Craven.
"You"ll come up to my quarters, now, and meet Lieutenant Ridder,"
announced the Major, when he had gathered the submarine boys together, and when Jack had given necessary explanations to Williamson.
"You may not see us again, for a few days," Jack informed the machinist, in winding up.
"That won"t surprise me so very much, either," laughed the machinist.
"Things are always happening, where you are, and mysteries have ceased to puzzle me."
"Have you young men ever been on a military post before?" inquired Major Woodruff, as he led them up from the dock.
"Never sir," replied Jack. "We have seen considerable of Navy life, but this is the first time we"ve ever been at a fort."
"You don"t see much about this place, do you," laughed the engineer officer, "that makes you think of a fort?"
"Not much," Benson admitted.
"Yet we have a fighting plant here that could prevent a big fleet, indeed, from getting far up the bay at the important cities beyond.
That is," Woodruff continued, thoughtfully, in a low voice, "if the enemy, in advance of his coming here, doesn"t know all about our defenses through the work of spies."
Just at the point near the dock, Fort Craven looked not unlike the yard of a big factory plant. Wagons going and coming constantly heightened this effect. Beyond, past the plain, on one side, Major Woodruff pointed out the barracks of the Coast Artillery, of the Engineers soldiers, and of the Infantry. There were also laborers" quarters, several office buildings, a hospital, a chapel, and two streets of cottages that served as quarters for the officers stationed at Fort Craven.
It was into one of these officers" streets that Major Woodruff soon led his three young companions. Admitting the boys to his home, the major took them to the library on the ground floor.
"Now, I"ll telephone for Lieutenant Ridder to come over in citizen"s dress," announced the major. "At the same time, I must advise Colonel Totten, who is commander of the post. He may come over here, or he may order us all over to headquarters."
Colonel Totten elected to come over to the major"s quarters. He arrived just after Lieutenant Ridder, who proved to be a rather boyish looking young man, not long out of West Point.
The plans were quickly laid by which Lieutenant Ridder was to take an automobile up to Radford, going to one of the hotels and registering.
Jack and his two chums were to make the journey in another auto. They would go to still other hotels, perhaps to three different ones. At any moment when instructions were needed, any one of the three could call up Lieutenant Ridder on the telephone.
In addition, Major Woodruff gave each of the three submarine boys a written and signed authorization for them to call upon the police to seize Millard, if found, and hold the fellow for the United States military authorities.
"Now, you young men may start for Radford," continued the major.
"Colonel Totten and I will busy ourselves with the despatches that must be sent to Washington about this affair. But I trust, lads, you will not fail to realize the importance of prompt success."
"It"s a special duty to the Flag, sir," Captain Jack answered, simply.
The automobiles were waiting outside. Lieutenant Ridder was given a three minutes" start. Then the submarine boys followed after, in a second car.
As Radford was but four miles distant from the post the trip was not to be a long one.
"This is the sort of job that has me by the ears," glowed Eph Somers, enthusiastically. "I won"t be selfish enough to say I hope to be the fellow to catch Millard. But, if he does stray my way, I hope I won"t be idiot enough to let him slip through my fingers."
"I don"t care if Lieutenant Ridder is the one who nabs him," remarked Hal, coolly. "All that I"m particular about is to see this foreign agent nabbed before he succeeds in getting any information out of the country."
The car that bore the boys was soon driving through the streets of Radford. Jack held in his hand a list of the better grade and middle-cla.s.s hotels that Colonel Totten had given him.
"Which hotel are we going to first?" asked Hal.
"I don"t know," uttered Jack, suddenly, sharply. "I know what I"m going to do, however."
Leaning slightly forward the young submarine captain prodded the chauffeur lightly, twice, in the back--a signal that had been agreed upon at need.
In response, the chauffeur ran the car slowly in at the curb.
Captain Jack, opening the tonneau door, was quickly out on the sidewalk, without any need having risen for wholly stopping the car, which then shot forward again.
"Now, what on earth was that for?" demanded Eph Somers, as the car sped on.
"Don"t look back," replied Hal.
"Why not?"
"Well, a certain party would see you looking at him."
"Who?"
"Why, Jack had the good luck to see Millard going along on the sidewalk.
We"ve just pa.s.sed the fellow!"
"Are we going to nab him?" demanded Somers, breathlessly.
"You"ll have to leave that decision to good old Jack," chuckled Hal Hastings. "He"s out there, d.o.g.g.i.ng Millard from the rear. It"s Jack Benson"s affair just at this moment."
