"The ambassador!" Miss Thorne whispered thrillingly.

XIV

A RESCUE AND AN ESCAPE

Miss Thorne's voice startled Mr. Grimm a little, but he had no doubts.

It was Monsieur Boisségur. Mr. Grimm was going toward the enframed

figure when, without any apparent reason, the ambassador turned and ran

along the hall; and at that instant the lights went out again. For one

moment Grimm stood still, dazed and blinded by the sudden blackness, and

again he started toward the door. Miss Thorne was beside him.

"The lights!" he whispered tensely. "Find the switch!"

He heard the rustle of her skirts as she moved away, and stepped out

into the hall, feeling with both his hands along the wall. A few feet

away, in the direction the ambassador had gone, there seemed to be a

violent struggle in progress--there was the scuffling of feet, and

quick-drawn breaths as muscle strained against muscle. The lights! If he

could only find the switch! Then, as his hands moved along the wall,

they came in contact with another hand--a hand pressed firmly against

the plastering, barring his progress. A light blow in the face caused

him to step back quickly.

The scuffling sound suddenly resolved itself into moving footsteps, and

the front door opened and closed with a bang. Mr. Grimm's listless eyes

snapped, and his white teeth came together sharply as he started toward

the front door. But fate seemed to be against him still. He stumbled

over a chair, and his own impetus forward sent him sprawling; his head

struck the wall with a resounding whack; and then, over the house, came

utter silence. From outside he heard the clatter of a cab. Finally that

died away in the distance.

"Miss Thorne?" he inquired quietly.

"I'm here," she answered in a despairing voice. "But I can't find the

switch."

"Are you hurt?"

"No."

And then she found the switch; the lights flared up. Mr. Grimm was

sitting thoughtfully on the floor.

"That simplifies the matter considerably," he observed complacently, as

he rose. "The men who signaled to me when you entered the embassy will

never let that cab get out of their sight."

Miss Thorne stood leaning forward a little, eagerly gazing at him with

those wonderful blue-gray eyes, and an expression of--of--perhaps it was

admiration on her face.

"Are you sure?" she demanded, at last.

"I know it," was his response.

And just then Monsieur Rigolot, secretary of the embassy, thrust an

inquisitive head timidly around the corner of the stairs. The crash of

glass had aroused him.

"What happened?" he asked breathlessly.

"We don't know just yet," replied Mr. Grimm. "If the noise aroused any

one else please assure them that there's nothing the matter. And you

might inform Madame Boisségur that the ambassador will return home

to-morrow. Good night!"

At his hotel, when he reached there, Mr. Grimm found Miss Thorne's

card--and he drew a long breath; at his office he found another of her

cards, and he drew another long breath. He did like corroborative

details, did Mr. Grimm, and, of course, this--! On the following day

Miss Thorne accompanied him to Alexandria, and they were driven in a

closed carriage out toward the western edge of the city. Finally the

carriage stopped at a signal from Mr. Grimm, and he assisted Miss Thorne

out, after which he turned and spoke to some one remaining inside--a

man.

"The house is two blocks west, along that street there," he explained,

and he indicated an intersecting thoroughfare just ahead. "It is number

ninety-seven. Five minutes after we enter you will drive up in front of

the door and wait. If we don't return in fifteen minutes--come in after

us!"

"Do you anticipate danger?" Miss Thorne queried quickly.

"If I had anticipated danger," replied Mr. Grimm, "I should not have

permitted you to come with me."

They entered the house--number ninety-seven--with a key which Mr. Grimm

produced, and a minute or so later walked into a room where three men

were sitting. One of them was of a coarse, repulsive type, large and

heavy; another rather dapper, of superficial polish, evidently a

foreigner, and the third--the third was Ambassador Boisségur!

"Good morning, gentlemen!" Mr. Grimm greeted them, then ceremoniously:

"Monsieur Boisségur, your carriage is at the door."

The three men came to their feet instantly, and one of them--he of the

heavy face--drew a revolver. Mr. Grimm faced him placidly.

"Do you know what would happen to you if you killed me?" he inquired

pleasantly. "You wouldn't live three minutes. Do you imagine I came in

here blindly? There are a dozen men guarding the entrances to the

house--a pistol shot would bring them in. Put down the gun!"

Eyes challenged eyes for one long tense instant, and the man carefully

laid the weapon on the table. Mr. Grimm strolled over and picked it up,

after which he glanced inquiringly at the other man--the ambassador's

second guard.

"And you are the gentleman, I dare say, who made the necessary trips to

the ambassador's house, probably using his latch-key?" he remarked

interrogatively. "First for the letters to be signed, and again for the

cigarettes?"

There was no answer and Mr. Grimm turned questioningly to Monsieur

Boisségur, silent, white of face, motionless.

"Yes, Monsieur," the ambassador burst out suddenly. His eyes were fixed

unwaveringly on Miss Thorne.

"And your escape, Monsieur?" continued Mr. Grimm.

"I did escape, Monsieur, last night," the ambassador explained, "but

they knew it immediately--they pursued me into my own house, these two

and another--and dragged me back here! _Mon Dieu, Monsieur, c'est--!_"

"That's all that's necessary," remarked Mr. Grimm. "You are free to go

now."

"But there are others," Monsieur Boisségur interposed desperately, "two

more somewhere below, and they will not allow--they will attack--!"

Mr. Grimm's listless eyes narrowed slightly and he turned to Miss

Thorne. She was a little white, but he saw enough in her face to satisfy

him.

"I shall escort Monsieur Boisségur to his carriage, Miss Thorne," he

said calmly. "These men will remain here until I return. Take the

revolver. If either of them so much as wags his head--_shoot_! You are

not--not afraid?"

"No." She smiled faintly. "I am not afraid."

Mr. Grimm and the ambassador went down the stairs, and out the front

door. Mr. Grimm was just turning to reenter the house when from above

came a muffled, venomous cra-as-ash!--a shot! He took the steps going

up, two at a time. Miss Thorne was leaning against the wall as if dazed;

the revolver lay at her feet. A door in a far corner of the room stood

open; and the clatter of footsteps echoed through the house.

"One of them leaped at me and I fired," she gasped in explanation. "He

struck me, but I'm--I'm not hurt."

She stooped quickly, picked up the revolver and made as if to follow the

dying footsteps. Mr. Grimm stopped her.

"It doesn't matter," he said quietly. "Let them go." And after a while,

earnestly: "If I had dreamed of such a--such a thing as this I should

never have consented to allow you--"

"I understand," she interrupted, and for one instant her outstretched

hand rested on his arm. "The ambassador?"

"Perfectly safe," responded Mr. Grimm. "Two of my men are with him."

XV

MASTER OF THE SITUATION

As the women rose and started out, leaving the gentlemen over their

coffee and cigars, Miss Thorne paused at the door and the blue-gray eyes

flashed some subtle message to the French ambassador who, after an

instant, nodded comprehendingly, then resumed his conversation. As he

left the room a few minutes later he noticed that Mr. Grimm had joined a

group of automaniacs of which Mr. Cadwallader was the enthusiastic

center. He spoke to his hostess, the wife of the minister from Portugal,

for a moment, then went to Miss Thorne and dropped into a seat beside

her. She greeted him with a smile and was still smiling as she talked.

"I believe, Monsieur," she said in French, "you sent a code message to

the cable office this afternoon?"

His eyes questioned hers quickly.

"And please bear in mind that we probably are being watched as we talk,"

she went on pleasantly. "Mr. Grimm is the man to be afraid of.

Smile--don't look so serious!" She laughed outright.

"Yes, I sent a code message," he replied.

"It was your resignation?"

"Yes."

"Well, it wasn't sent, of course," she informed him, and her eyes were

sparkling as if something amusing had been said. "One of my agents

stopped it. I may add that it will not be sent."

The ambassador's eyes grew steely, then blank again.

"Mademoiselle, what am I to understand from that?" he demanded.

"You are to understand that I am absolute master of the situation in

Washington at this moment," she replied positively. The smile on her

lips and the tone of her voice were strangely at variance. "From the

beginning I let you understand that ultimately you would receive your

instructions from Paris; now I know they will reach you by cable

to-morrow. Within a week the compact will be signed. Whether you approve

of it or not it will be signed for your country by a special envoy whose

authority is greater than yours--his Highness, the Prince Benedetto

d'Abruzzi."

"Has he reached Washington?"

"He is in Washington. He has been here for some time, incognito." She

was silent a moment. "You have been a source of danger to our plans,"

she added. "If it had not been for an accident you would still have been

comfortably kept out in Alexandria where Mr. Grimm and I found you.

Please remember, Monsieur, that we will accomplish what we set out to

do. Nothing can stop us--nothing."

At just about the same moment the name of Prince d'Abruzzi had been used

in the dining-room, but in a different connection. Mr. Cadwallader was

reciting some incident of an automobile trip in Italy when he had been

connected with the British embassy there.

"The prince was driving," he said, "and one of the best I ever saw.

Corking chap, the prince; democratic, you know, and all that sort of

thing. He was one scion of royalty who didn't mind soiling his hands by

diving in under a car and fixing it himself. At that time he was

inclined to be wild--that was eight or nine years ago--but they say now

he has settled down to work, and is one of the real diplomatic powers of

Italy. I haven't seen him for a half dozen years."

"How old a man is he?" asked Mr. Grimm carelessly.

"Thirty-five, thirty-eight, perhaps; I don't know," replied Mr.

Cadwallader. "It's odd, you know, the number of princes and blue-bloods

and all that sort of thing one can find knocking about in Italy and

Germany and Spain. One never hears of half of them. I never had heard

of the Prince d'Abruzzi until I went to Italy, and I've heard jolly well

little of him since, except indirectly."

Mr. Cadwallader lapsed into silence as he sat staring at a large group

photograph which was framed on a wall of the dining-room.

"Isn't that the royal family of Italy?" he asked. He rose and went over

to it. "By Jove, it is, and here is the prince in the group. The picture

was taken, I should say, about the time I knew him."

Mr. Grimm strolled over idly and stood for a long time staring at the

photograph.

"He can drive a motor, you know," said Mr. Cadwallader admiringly. "And

Italy is the place to drive them. They forgot to make any speed laws

over there, and if a chap gets in your way and you knock him silly they

arrest him for obstructing traffic, you know. Over here if a chap really

starts to go any place in a hurry some bally idiot holds him up."

"Have you ever been held up?" queried Mr. Grimm.

"No, but I expect to be every day," was the reply. "I've got a new

motor, you know, and I've never been able to see how fast it is. The

other evening I ran up to Baltimore with it in an hour and thirty-seven

minutes from Alexandria to Druid Hill Park, and that's better than forty

miles. I never did let the motor out, you know, because we ran in the

dark most of the way."

Mr. Grimm was still gazing at the photograph.

"Did you go alone?" he asked.

"There's no fun motoring alone, you know. Señorita Rodriguez was with

me. Charming girl, what?"

A little while later Mr. Grimm sauntered out into the drawing-room and

made his way toward Miss Thorne and the French ambassador. Monsieur

Boisségur rose, and offered his hand cordially.

"I hope, Monsieur," said Mr. Grimm, "that you are no worse off for

your--your unpleasant experience?"

"Not at all, thanks to you," was the reply. "I have just thanked Miss

Thorne for her part in the affair, and--"

"I'm glad to have been of service," interrupted Mr. Grimm lightly.

The ambassador bowed ceremoniously and moved away. Mr. Grimm dropped

into the seat he had just left.

"You've left the legation, haven't you?" he asked.

"You drove me out," she laughed.

"Drove you out?" he repeated. "Drove you out?"

"Why, it was not only uncomfortable, but it was rather conspicuous

because of the constant espionage of your Mr. Blair and your Mr. Johnson

and your Mr. Hastings," she explained, still laughing. "So I have moved

to the Hotel Hilliard."

Mr. Grimm was twisting the seal ring on his little finger.

"I'm sorry if I've made it uncomfortable for you," he apologized. "You

see it's necessary to--"

"No explanation," Miss Thorne interrupted. "I understand."

"I'm glad you do," he replied seriously. "How long do you intend to

remain in the city?"

"Really I don't know--two, three, four weeks, perhaps. Why?"

"I was just wondering."

Señorita Rodriguez came toward them.

"We're going to play bridge," she said, "and we need you, Isabel, to

make the four. Come. I hate to take her away, Mr. Grimm."

Mr. Grimm and Miss Thorne rose together. For an instant her slim white

hand rested on Mr. Grimm's sleeve and she stared into his eyes

understandingly with a little of melancholy in her own. They left Mr.

Grimm there.

XVI

LETTERS FROM JAIL

For two weeks Signor Pietro Petrozinni, known to the Secret Service as

an unaccredited agent of the Italian government, and the self-confessed

assailant of Señor Alvarez of the Mexican legation, had been taking his

ease in a cell. He had been formally arraigned and committed without

bail to await the result of the bullet wound which had been inflicted

upon the diplomatist from Mexico at the German Embassy Ball, and, since

then, undisturbed and apparently careless of the outcome, he had spent

his time in reading and smoking. He had answered questions with only a

curt yes or no when he deigned to answer them at all; and there had been

no callers or inquiries for him. He had abruptly declined a suggestion

of counsel.

Twice each day, morning and night, he had asked a question of the

jailer who brought his simple meals.

"How is Señor Alvarez?"

"He is still in a critical condition." The answer was always the same.

Whereupon the secret agent would return to his reading with not a shadow

of uneasiness or concern on his face.

Occasionally there came a courteous little note from Miss Thorne, which

he read without emotion, afterward casting them aside or tearing them

up. He never answered them. And then one day there came another note

which, for no apparent reason, seemed to stir him from his lethargy.

Outwardly it was like all the others, but when Signor Petrozinni scanned

the sheet his eyes lighted strangely, and he stood staring down at it as

though to hide a sudden change of expression in his face. His gaze was

concentrated on two small splotches of ink where, it seemed, the pen

had scratched as Miss Thorne signed her name.

The guard stood at the barred door for a moment, then started to turn

away. The prisoner stopped him with a quick gesture.

"Oh, Guard, may I have a glass of milk, please?" he asked. "No ice. I

prefer it tepid."

He thrust a small coin between the bars; the guard accepted it and

passed on. Then, still standing at the door, the prisoner read the note

again:

"MY DEAR FRIEND:

"I understand, from an indirect source, that there has been a marked

improvement in Señor Alvarez's condition, and I am hastening to send you

the good news. There is every hope that within a short while, if he

continues to improve, we can arrange a bail bond, and you will be free

until the time of trial anyway.

"Might it not be well for you to consult an attorney at once? Drop me a

line to let me know you received this.

"Sincerely,

"ISABEL THORNE."

Finally the prisoner tossed the note on a tiny table in a corner of his

cell, and resumed his reading. After a time the guard returned with the

milk.

"Would it be against the rules for me to write an answer to this?"

queried Signor Petrozinni, and he indicated the note.

"Certainly not," was the reply.

"If I might trouble you, then, for pen and ink and paper?" suggested the

signor and he smiled a little. "Believe me, I would prefer to get them

for myself."

"I guess that's right," the guard grinned good-naturedly.

Again he went away and the prisoner sat thoughtfully sipping the milk.

He took half of it, then lighted a cigarette, puffed it once or twice

and permitted the light to die. After a little there came again the

clatter of the guard's feet on the cement pavement, and the writing

materials were thrust through the bars.

"Thank you," said the prisoner.

The guard went on, with a nod, and a moment later the signor heard the

clangor of a steel door down the corridor as it was closed and locked.

He leaned forward in his chair with half-closed eyes, listening for a

long time, then rose and noiselessly approached the cell door. Again he

listened intently, after which he resumed his seat. He tossed away the

cigarette he had and lighted a fresh one, afterward holding the note

over the flame of the match. Here and there, where the paper charred in

the heat, a letter or word stood out from the bare whiteness of the

paper, and finally, a message complete appeared between the innocuous

ink-written lines. The prisoner read it greedily:

"Am privately informed there is little chance of Alvarez's recovery.

Shall I arrange escape for you, or have ambassador intercede? Would

advise former, as the other might take months, and meeting to sign

treaty alliance would be dangerously delayed."

Signor Petrozinni permitted the sputtering flame to ignite the paper,

and thoughtfully watched the blaze destroy it. The last tiny scrap

dropped on the floor, burned out, and he crushed the ashes under his

heel. Then he began to write:

"My Dear Miss Thorne:

"Many thanks for your courteous little note. I am delighted to know of

the improvement in Señor Alvarez's condition. I had hoped that my

impulsive act in shooting him would not end in a tragedy. Please keep me

informed of any further change in his condition. As yet I do not see the

necessity of consulting an attorney, but later I may be compelled to do

so.

"Respectfully,

"Pietro Petrozinni."

This done the secret agent carefully cleaned the ink from the pen,

wiping it dry with his handkerchief, then thrust it into the half empty

glass of milk. The fluid clung to the steel nib thinly; he went on

writing with it, between the lines of ink:

"I am in no danger. I hold credentials to United States, which, when

presented, will make me responsible only to the Italian government as

special envoy, according to international law. Arrange escape for one

week from to-night; use any money necessary. Make careful arrangements

for the test and signing of compact for two nights after."

Again the prisoner cleaned the steel nib, after which he put it back in

the bottle of ink, leaving it there. He waved the sheet of paper back

and forth to dry it, and at last scrutinized it minutely, standing under

the light from the high-up window of his cell. Letter by letter the milk

evaporated, leaving the sheet perfectly clean and white except for the

ink-written message. This sheet he folded, placed in an envelope, and

addressed.

Later the guard passed along the corridor, and Signor Petrozinni thrust

the letter out to him.

"Be good enough to post that, please," he requested. "It isn't sealed. I

don't know if your prison rules require you to read the letters that go

out. If so, read it, or have it read, then seal it."

For answer the guard dampened the flap of the envelope, sealed it,

thrust it into his pocket and passed on. The secret agent sat down

again, and sipped his milk meditatively.

One hour later Mr. Grimm, accompanied by Johnson, came out of a

photographer's dark room in Pennsylvania Avenue with a developed

negative which he set on a rack to dry. At the end of another hour he

was sitting at his desk studying, under a magnifying glass, a finished

print of the negative. Word by word he was writing on a slip of paper

what his magnifying glass gave him and so, curiously enough, it came to

pass that Miss Thorne and Chief Campbell of the Secret Service were

reading the hidden, milk-written message at almost the identical moment.

"Johnson got Petrozinni's letter from the postman," Mr. Grimm was

explaining. "I opened it, photographed it, sealed it again and remailed

it. There was not more than half an hour's delay; and Miss Thorne can

not possibly know of it." He paused a moment. "It's an odd thing that

writing such as that is absolutely invisible to the naked eye, and yet

when photographed becomes decipherable in the negative."

"What do you make of it?" Mr. Campbell asked. The guileless blue eyes

were alive with eagerness.

"Well, he's right, of course, about not being in danger," said Mr.

Grimm. "If he came with credentials as special envoy this government

must respect them, even if Señor Alvarez dies, and leave it to his own

government to punish him. If we were officially aware that he has such

credentials I doubt if we would have the right to keep him confined; we

would merely have to hand him over to the Italian embassy and demand his

punishment. And, of course, all that makes him more dangerous than

ever."

"Yes, I know that," said the chief a little impatiently. "But who is

this man?"

"Who is this man?" Mr. Grimm repeated as if surprised at the question.

"I was looking for Prince Benedetto d'Abruzzi, of Italy. I have found

him."

Mr. Campbell's clock-like brain ticked over the situation in detail.

"It's like this," Mr. Grimm elucidated. "He has credentials which he

knows will free him if he is forced to present them, but I imagine they

were given to him more for protection in an emergency like this than for

introducing him to our government. As the matter stands he can't afford

to discover himself by using those credentials, and yet, if the Latin

compact is signed, he must be free. Remember, too, that he is accredited

from three countries--Italy, France and Spain." He was silent for a

moment. "Naturally his escape from prison would preserve his incognito,

and at the same time permit him to sign the compact."

There was silence for a long time.

"I believe the situation is without precedent," said Mr. Campbell

slowly. "The special envoy of three great powers held for attempted--!"

"Officially we are not aware of his purpose, or his identity," Mr. Grimm

reminded him. "If he escaped it would clarify the situation

tremendously."

"If he escaped!" repeated Mr. Campbell musingly.

"But, of course, the compact would not be signed, at least in this

country," Mr. Grimm went on tentatively.

Mr. Campbell gazed straight into the listless eyes of the young man for

a minute or more, and gradually full understanding came home to him.

Finally he nodded his head.

"Use your own judgment, Mr. Grimm," he directed.

XVII

A CALL ON THE WARDEN

The restful silence of night lay over the great prison. Here and there

in the grim corridors a guard dozed in the glare of an electric light;

and in the office, too, a desk light glimmered where the warden sat at

his desk, poring over a report. Once he glanced up at the clock--it was

five minutes of eleven--and then he went on with his reading.
