"Was this the only copy in existence?"
"There are two others--one in the possession of the Secretary, the other in the section which has charge of decoding messages. Both of these are safe, as I ascertained as soon as I discovered that my slip was missing."
A few more questions failed to bring out anything more about the mystery beyond the fact that the a.s.sistant Secretary was certain that he had locked the safe the evening before and he knew that he had found it locked when he arrived that morning.
"All of which," as Taylor declared, "means but little. The safe is of the vintage of eighteen seventy, the old-fashioned kind where you can hear the tumblers drop clean across the room. Look!" and he pointed to the j.a.panned front of the safe where a circular mark, some two inches in diameter, was visible close to the dial.
"Yes, but what is it?" demanded the Secretary.
"The proof that you locked the safe last night," Taylor responded.
"Whoever abstracted the cipher key opened the safe with the aid of some instrument that enabled them clearly to detect the fall of the tumblers.
Probably a stethoscope, such as physicians use for listening to a patient"s heart. Perfectly simple when you know how--particularly with an old model like this."
Finding that there was no further information available, Taylor and the chief left the department, the chief to return to headquarters, Taylor to endeavor to pick up the trail wherever he could.
"It doesn"t look like an inside job," was the parting comment of the head of the Secret Service. "Anyone who had access to the safe would have made some excuse to discover the combination, rather than rely on listening to the click of the tumblers. Better get after the night watchman and see if he can give you a line on any strangers who were around the building last night."
But the night watchman when roused from his sound forenoon"s sleep was certain that no one had entered the building on the previous evening save those who had business there.
"Everybody"s got to use a pa.s.s now, you know," he stated. "I was on the job all night myself an" divvle a bit of anything out of the ordinary did I see. There was Mr. McNight and Mr. Lester and Mr. Greene on the job in the telegraph room, and the usual crowd of correspondents over in the press room, and a score of others who works there regular, an" Mrs.
Prentice, an"--"
"Mrs. who?" interrupted Taylor.
"Mrs. Prentice, wife of th" Third a.s.sistant Secretary. She comes down often when her husband is working late, but last night he must have gone home just before she got there, for she came back a few minutes later and said that the office was dark."
Whatever Taylor"s thoughts were at the moment he kept them to himself--for Prentice was the man from whose safe the cipher key had been abstracted!
So he contented himself with inquiring whether the watchman was certain that the woman who entered the building was Mrs. Prentice.
"Shure an" I"m certain," was the reply. "I"ve seen her and that green evening cape of hers trimmed with fur too often not to know her."
"Do you know how long it was between the time that she entered the building and the time she left?" persisted Taylor.
"That I do not, sir. Time is something that you don"t worry about much when it"s a matter of guarding the door to a building--particularly at night. But I"d guess somewhere about five or ten minutes?"
"Rather long for her to make her way to the office of her husband, find he wasn"t there, and come right back, wasn"t it?"
"Yes, sir--but you must remember I wasn"t countin" the minutes, so to speak. Maybe it was only three--maybe it was ten. Anyhow, it was just nine-thirty when she left. I remember looking at the clock when she went out."
From the watchman"s house, located well over in the northeastern section of the city, Taylor made his way to Madelaine James"s apartment on Connecticut Avenue, discovering that young lady on the point of setting off to keep a luncheon engagement.
"I won"t keep you a minute, Madelaine," promised the Secret Service operative. "Just want to ask what you know about Mrs. Mahlon Prentice?"
"Wife of the Third a.s.sistant Secretary of State?"
Taylor nodded.
"She"s a Chicago woman, I believe. Came here a couple of years ago when her husband received his appointment. Rather good-looking and very popular. I happened to be at a dinner with her last evening and--"
"You what?"
"I was at a dinner at the Westovers" last night," repeated the James girl, "and Mrs. Prentice was among those present. Looked stunning, too.
What"s the trouble?"
"What time was the dinner?" Taylor countered.
"Eight o"clock, but of course it didn"t start until nearly eight-thirty."
"And what time did Mrs. Prentice leave?"
"A few minutes after I did. She was just going up for her wraps as I came downstairs at eleven o"clock."
"You are certain that she was there all evening--that she didn"t slip out for half an hour or so?"
"Of course I"m sure, Mell," the girl replied, a trace of petulance in her voice. "Why all the questions? Do you suspect the wife of the Third a.s.sistant Secretary of State of robbing a bank?"
"Not a bank," Taylor admitted, "but it happens that the safe in her husband"s office was opened last night and a highly important slip of paper abstracted. What"s more, the watchman on duty in the building is ready to swear that Mrs. Prentice came in shortly before nine-thirty, and went out some five or ten minutes later, stating that her husband had evidently finished his work and left."
"That"s impossible! No matter what the watchman says, there are a score of people who dined with Mrs. Prentice last evening and who know that she didn"t leave the Westovers" until after eleven. Dinner wasn"t over by nine-thirty, and she couldn"t have gotten to the State Department and back in less than twenty minutes at the inside. It"s ridiculous, that"s all!"
"But the watchman!" exclaimed Taylor. "He knows Mrs. Prentice and says he couldn"t miss that green-and-fur coat of hers in the dark. Besides, she spoke to him as she was leaving."
Madelaine James was silent for a moment, and a tiny frown appeared between her eyes, evidence of the fact that she was doing some deep thinking.
Then: "Of course she spoke! Anyone who would go to the trouble of copying Mrs. Prentice"s distinctive cloak would realize that some additional disguise was necessary. Last night, if you remember, was quite cold. Therefore it would be quite natural that the woman who impersonated Mrs. Prentice should have her collar turned up around her face and probably a drooping hat as well. The collar, in addition to concealing her features, would m.u.f.fle her voice, while the watchman, not suspecting anything, would take it for granted that the green cloak was worn by the wife of the Under Secretary--particularly when she spoke to him in pa.s.sing."
"You mean, then, that some one deliberately impersonated Mrs. Prentice and took a chance on getting past the watchman merely because she wore a cloak of the same color?"
"The same color--the same style--practically the same coat," argued Miss James. "What"s more, any woman who would have the nerve to try that would probably watch Prentice"s office from the outside, wait for the light to go out, and then stage her visit not more than five minutes later, so"s to make it appear plausible. How was the safe opened?"
"Stethoscope. Placed the cup on the outside, and then listened to the tumblers as they fell. Simplest thing in the world with an antiquated box like that."
"What"s missing?"
By this time Taylor felt that their positions had been reversed. He, who had come to question, was now on the witness stand, while Madelaine James was doing the cross-examining. But he didn"t mind. He knew the way the girl"s mind worked, quickly and almost infallibly--her knowledge of women in general and Washington society in particular making her an invaluable ally in a case like this.
"A slip of paper some six inches long and two inches wide," he said, with a smile. "The key to the Carruthers Code, probably the most efficient cipher in the world, but now rendered worthless unless the original slip is located before it reaches some foreign power."
"Right!" snapped Miss James. "Get busy on your end of the matter. See what you can find out concerning this mysterious woman in the green cloak. I"ll work along other and what you would probably call strictly unethical lines. I"ve got what a man would term a "hunch," but in a woman it is "intuition"--and therefore far more likely to be right. See you later!" and with that she was off toward her car.
"But what about your luncheon engagement?" Taylor called after her.
"Bother lunch," she laughed back over her shoulder. "If my hunch is right I"ll make your chief pay for my meals for the next year!"
The next that Taylor heard from his ally was a telephone call on the following evening, instructing him to dig up his evening clothes and to be present at a certain reception that evening.
"I have reason to believe," said Madelaine"s voice, "that the lady of the second green cloak will be present. Anyhow, there"ll be several of your friends there--including myself, Mrs. Armitage, and an amba.s.sador who doesn"t stand any too well with the Administration. In fact, I have it on good authority that he"s on the verge of being recalled. Naturally we don"t want him to take a slip of paper, some six inches by two, with him!"
