Mr. Carleton Conne, of the United States Secret Service, had come over from Liverpool via Dover on a blind quest after an elusive spy. There had been a sort of undercurrent of rumor, with many extravagant trappings, that a mysterious agent of the Kaiser was on his way to Europe with secrets of a most important character. Some stories had it that he was intimately related to Bloody Bill himself; others that he gloried in a kinship with Ludendorf, while still other versions represented him as holding Mexico in the palm of his hand. Dark stories floated about and no one knew just where they originated.

One sprightly form this story took, which had been whispered in New York and then in Liverpool, was that a certain young lady (identity unknown) had talked with a soldier (identity unknown) in the Grand Central Station in New York, and that the soldier had told her that at his cantonment (cantonment not identified) there was a man in a special branch of the service (branch not mentioned) who was a cousin or a brother or a nephew or a son or something or other to a German general or statesman or something or other, and that he had got into the American army by a pretty narrow squeak. There seemed to be a unanimity of opinion in the lower strata of Uncle Sam's official family in Liverpool that the soldier who had talked with the young lady was coming over on the transport Manchester and it was assumed (no one seemed to know exactly why) that the mysterious and sinister personage would be upon the same ship.

But no soldier had been found upon the Manchester who showed by his appearance that he had chatted with a young lady. Perhaps several of them had done that. It is a way soldiers have.

As for the arch spy or propagandist, he did not come forward and introduce himself as such, and though a few selected suspects of German antecedents were searched and catechised by Mr. Conne and others, no one was held.

And there you are.

Rumors of this kind are always in circulation and the Secret Service people run them down as a matter of precaution. But though you can run a rumor down and stab it through and through you cannot kill it. It now appeared that this German agent had sailed from Mexico and would land at Brest—with a message to some French statesman. Also it appeared that he had stolen a secret from Edison and would land at Dieppe. It had also been reported that someone had attempted to blow up the loaded transport Texas Pioneer on her way over.

And so Mr. Carleton Conne, of the American Secret Service, quiet, observant, uncommunicative, never too sanguine and never too skeptical, had strolled on to the Channel Queen, lighted his cigar, and was now tilted back in his chair outside the Quartermaster's office in Dieppe, not at all excited and waiting for the Texas Pioneer to dock.

He had done this because he believed that where there is a great deal of smoke there is apt to be a little fire. He was never ruffled, never disappointed.

Tom's acquaintance with Mr. Conne had begun on the transport on which he had worked as a steward's boy, and where his observant qualities and stolid soberness had attracted and amused the detective.

"I never thought I'd see you here," said Tom, his face lighting up to an unusual degree. "I'm a dispatch-rider now. I just rode from Cantigny. I got a letter for the Quartermaster, but anyway he's got to turn me over to the Secret Service (Mr. Conne regarded him with whimsical attention as he stumbled on), because there's a plot and somebody—a spy—kind of——"

"A spy, kind of, eh?"

"And I hope the Texas Pioneer didn't land yet, that's one sure thing."

"It's one sure thing that she'll dock in about fifteen minutes, Tommy," said Mr. Conne rising. "Come inside and deliver your message. What's the matter with your machine? Been trying to wipe out the Germans alone and unaided, like the hero in a story book?"

Tom followed him in, clumsily telling the story of his exciting journey; "talking in chunks," as he usually did and leaving many gaps to be filled in by the listener.

"I'm glad I found you here, anyway," he finished, as if that were the only part that really counted; "'cause now I feel as if I can tell about an idea I've got. I'd of been scared to tell it to anybody else. I ain't exactly got it yet," he added, "but maybe I can help even better than they thought, 'cause as I was ridin' along I had a kind of an idea——"

"Yes?"

"Kind of. Did you ever notice how you get fool ideas when there's a steady noise going on?"

"So?" said Mr. Conne, as he led the way along a hall.

"It was the noise of my machine."

"How about the smell, Tommy?" Mr. Conne asked, glancing around with that pleasant, funny look which Tom had known so well.

"You don't get ideas from smells," he answered soberly.

In the Quartermaster's office he waited on a bench while Mr. Conne and several other men, two in uniform and two that he thought might be Secret Service men, talked in undertones. If he had been a hero in a book, to use Mr. Conne's phrase, these officials would doubtless have been assembled about him listening to his tale, but as it was he was left quite out of the conference until, near its end, he was summoned to tell of his capture of Major von Piffinhoeffer and asked if he thought he could identify a close relation of that high and mighty personage simply by seeing him pass as a total stranger.

Tom thought he might "by a special way," and explained his knowledge of breed marks and specie marks. He added, in his stolid way, that he had another idea, too. But they did not ask him what that was. One of the party, a naval officer, expressed surprise that he had ridden all the way from Cantigny and asked him if it were not true that part of the road was made impassible by floods. Tom answered that there were floods but that they were not impassible "if you knew how." The officer said he supposed Tom knew how, and Tom regarded this as a compliment.

Soon, to his relief, Mr. Conne took all the papers in the case and left the room, beckoning Tom to follow him. Another man in civilian clothes hurried away and Tom thought he might be going to the dock. It seemed to him that his rather doubtful ability to find a needle in a haystack had not made much of an impression upon these officials, and he wondered ruefully what Mr. Conne thought. He saw that his arrival with the papers had produced an enlivening effect among the officials, but it seemed that he himself was not taken very seriously. Well, in any event, he had made the trip, he had beaten the ship, delivered the message to Garcia.

"I got to go down and turn my grease cup before I forget it," he said, as they came out on the little stone portico again.

Several soldiers who were soon to see more harrowing sights than a bunged-up motorcycle, were gathered about Uncle Sam, gaping at him and commenting upon his disfigurements. Big U. S. A. auto trucks were passing by. A squad of German prisoners, of lowering and sullen aspect, marched by with wheelbarrows full of gray blankets. They were keeping perfect step, through sheer force of habit. Another dispatch-rider (a "local") passed by, casting a curious eye at Uncle Sam. A French child who sat upon the step had one of his wooden shoes full of smoky, used bullets, which he seemed greatly to prize. Several "flivver" ambulances stood across the way, new and roughly made, destined for the front. American naval and military officers were all about.

"We haven't got much time to spare, Tommy," said Mr. Conne, resuming his former seat and glancing at his watch.

"It's only a second. I just got to turn the grease cup."

He hurried down past the child, who called him "M'sieu Yankee," and elbowed his way through the group of soldiers who were standing about Uncle Sam.

"Your timer bar's bent," one of them volunteered.

Tom did not answer, but knelt and turned the grease cup, then wiped the nickel surfaces, bent and dented though they were, with a piece of cotton waste. Then he felt of his tires. Then he adjusted the position of the handle-bar more to his liking and as he did so the poor, dented, glassless searchlight bobbed over sideways as if to look at the middle of the street. Tom said something which was not audible to the curious onlookers. Perhaps Uncle Sam heard.

The local rider came jogging around the corner on his way back. His machine was American-made and a medley of nickel and polished brass. As he made the turn his polished searchlight, with a tiny flag perched jauntily upon it, seemed to be looking straight at Uncle Sam. And Uncle Sam's green-besprinkled,[3] glassless eye seemed to be leering with a kind of sophisticated look at the passing machine. It was the kind of look which the Chicago Limited might give to the five-thirty suburban starting with its load of New York commuters for East Orange, New Jersey.
