Before she returned the new attendant had vanished, but Dick Walters, in his usual garb, was loitering around the only entrance to the reference room, watching the suspect out of the corner of his eye.
"I'm sorry," Mary reported, "but the Stevens book won't be in until to-morrow," and she was barely able to keep the anxiety out of her voice as she spoke.
Had Dick gotten her signal? Would he be able to trail his man? Could he capture him without being injured? These and a score of other questions rushed through her mind as she saw the German leave the room. Once outside – well, she'd have to wait for Dick to tell her what happened then.
The man who was interested in the chemistry of explosives apparently wasn't in the least afraid of being followed, for he took a bus uptown, alighted at Eighty-third Street, and vanished into one of the innumerable small apartment houses in that section of the city. Walters kept close behind him, and he entered the lobby of the apartment house in time to hear his quarry ascending to the fourth floor. Then he signaled to the four men who had followed him up the Avenue in a government-owned machine – men who had been stationed outside the Library in the event of just such an occurrence – and instructed two of them to guard the rear of the house, while the other two remained in front.
"I'm going to make this haul myself," Walters stated, "but I want you boys to cover up in case anything happens to me. No matter what occurs, don't let him get away. Shoot first and ask questions afterward!" and he had re-entered the house almost before he finished speaking.
On the landing at the third floor he paused long enough to give the men at the rear a chance to get located. Then – a quick ring at the bell on the fourth floor and he waited for action.
Nothing happened. Another ring – and still no response.
As he pressed the button for the third time the door swung slowly inward, affording only a glimpse of a dark, uninviting hall. But, once he was inside, the door closed silently and he heard a bolt slipped into place. Simultaneously a spot light, arranged over the doorway, flashed on and Dick was almost dazzled by the glare. Out of the darkness came the guttural inquiry:
"What do you want?"
"Not a thing in the world," replied Walters, "except to know if a man named Simpson lives here."
"No," came the voice, "he does not. Get out!"
"Sure I will if you'll pull back that bolt. What's the idea, anyhow? You're as mysterious as if you were running a bomb factory or something – "
As he spoke he ducked, for if the words had the effect he hoped, the other would realize that he was cornered and attempt to escape.
A guttural German oath, followed by a rapid movement of the man's hand toward his hip pocket was the reply. In a flash Dick slipped forward, bending low to avoid the expected attack, and seized the German in a half nelson that defied movement. Backing out of the circle of light, he held the helpless man in front of him – as a shelter in case of an attack from other occupants of the apartment – and called for assistance. The crash of glass at the rear told him that reinforcements had made their way up the fire escape and had broken in through the window. A moment later came the sound of feet on the stairs and the other two operatives were at the door, revolvers drawn and ready for action.
But there wasn't any further struggle. Von Ewald – or whatever his real name was, for that was never decided – was alone and evidently realized that the odds were overwhelming. Meekly, almost placidly, he allowed the handcuffs to be slipped over his wrists and stood by as the Secret Service men searched the apartment. Not a line or record was found to implicate anyone else – but what they did discover was a box filled with bombs precisely like those picked up on the scene of the Black Tom explosion, proof sufficient to send the German to the penitentiary for ten years – for our laws, unfortunately, do not permit of the death penalty for spies unless caught red-handed by the military authorities.
That he was the man for whom they were searching – the mysterious "No. 859" – was apparent from the fact that papers concealed in his desk contained full details as to the arrangement of the Nemours plant at Wilmington, Delaware, with a dozen red dots indicative of the best places to plant bombs. Of his associates and the manner in which he managed his organization there wasn't the slightest trace. But the Black Tom explosion, if you recall, was the last big catastrophe of its kind in America – and the capture of von Ewald was the reason that more of the German plots didn't succeed.
The Treasury Department realized this fact when Mary McNilless, on the morning of the day she was to be married to Dick Walters, U. S. S. S., received a very handsome chest of silver, including a platter engraved, "To Miss Mary McNilless, whose cleverness and keen perception saved property valued at millions of dollars."
No one ever found out who sent it, but it's a safe bet that the order came from Washington by way of Wilmington, where the Nemours plant still stands – thanks to the quickness of Mary's Irish eyes.

PHYLLIS DODGE, SMUGGLER EXTRAORDINARY
Bill Quinn tossed aside his evening paper and, cocking his feet upon a convenient chair, remarked that, now that peace was finally signed, sealed, and delivered, there ought to be a big boom in the favorite pastime of the idle rich.
"Meaning what?" I inquired.
"Smuggling, of course," said Quinn, who only retired from Secret Service when an injury received in action forced him to do so.
"Did you ever travel on a liner when four out of every five people on board didn't admit that they were trying to beat the customs officials one way or another – and the only reason the other one didn't follow suit was because he knew enough to keep his mouth shut. That's how Uncle Sam's detectives pick up a lot of clues. The amateur crook never realizes that silence is golden and that oftentimes speech leads to a heavy fine.
"Now that the freedom of the seas is an accomplished fact the whole crew of would-be smugglers will doubtless get to work again, only to be nabbed in port. Inasmuch as ocean travel has gone up with the rest of the cost of living, it'll probably be a sport confined to the comparatively rich, for a couple of years anyhow.
"It was different in the old days. Every steamer that came in was loaded to the eyes and you never knew when you were going to spot a hidden necklace or a packet of diamonds that wasn't destined to pay duty. There were thrills to the game, too, believe me.
"Why, just take the case of Phyllis Dodge…"
Mrs. Dodge [Quinn continued, after he had packed his pipe to a condition where it was reasonably sure to remain lighted for some time] was, theoretically at least, a widow. Her full name, as it appeared on many passenger lists during the early part of 1913, was Mrs. Mortimer C. Dodge, of Cleveland, Ohio. When the customs officials came to look into the matter they weren't able to find anyone in Cleveland who knew her, but then it's no penal offense to give the purser a wrong address, or even a wrong name, for that matter.
While there may have been doubts about Mrs. Dodge's widowhood – or whether she had ever been married, for that matter – there could be none about her beauty. In the language of the classics, she was there. Black hair, brown eyes, a peaches-and-cream complexion that came and went while you watched it, and a figure that would have made her fortune in the Follies. Joe Gregory said afterward that trailing her was one of the easiest things he had ever done.
To get the whole story of Phyllis and her extraordinary cleverness – extraordinary because it was so perfectly obvious – we'll have to cut back a few months before she came on the scene.
For some time the Treasury Department had been well aware that a number of precious stones, principally pearl necklaces, were being smuggled into the country. Agents abroad – the department maintains a regular force in Paris, London, Rotterdam, and other European points, you know – had reported the sale of the jewels and they had turned up a few weeks later in New York or Chicago. But the Customs Service never considers it wise to trace stones back from their owners on this side. There are too many ramifications to any well-planned smuggling scheme, and it is too easy for some one to claim that he had found them in a long-forgotten chest in the attic or some
