CHAPTER TWENTY-TWO: _The Corona Machine_

The detective's hand fell softly upon Frobisher's shoulder warning

him to silence; and this warning was needed. The lustres of the big

glass chandelier were so many flashing jewels; the mirrors of the

girandoles multiplied their candle-lamps; the small gay room was

ablaze; and in the glare Betty stood and laughed. Her white

shoulders rose from a slim evening frock of black velvet; from her

carefully dressed copper hair to her black satin shoes she was as

trim as if she had just been unpacked from a bandbox; and she was

laughing whole-heartedly at a closed sack on the divan, a sack which

jerked and flapped grotesquely like a fish on a beach. Some one was

imprisoned within that sack. Jim Frobisher could not doubt who that

some one was, and it seemed to him that no sound more soulless and

cruel had ever been heard in the world than Betty's merriment. She

threw her head back: Jim could see her slender white throat working,

her shoulders flashing and shaking. She clapped her hands with a

horrible glee. Something died within Frobisher's breast as he heard

it. Was it in his heart, he wondered? It was, however, to be the

last time that Betty Harlowe laughed.

"You can get her out, Francine," she said, and whilst Francine with a

pair of scissors cut the end of the sack loose, she sat down with her

back to it at the writing-table and unlocked a drawer. The sack was

cut away and thrown upon the floor, and now on the divan Ann Upcott

lay in her gleaming dancing-dress, her hands bound behind her back,

and her ankles tied cruelly together. Her hair was dishevelled, her

face flushed, and she had the look of one quite dazed. She drew in

deep breaths of air, with her bosom labouring. But she was unaware

for the moment of her predicament or surroundings, and her eyes

rested upon Francine and travelled from her to Betty's back without a

gleam of recognition. She wrenched a little at her wrists, but even

that movement was instinctive; and then she closed her eyes and lay

still, so still that but for her breathing the watchers at the door

would hardly have believed that she still lived.

Betty, meanwhile, lifted from the open drawer, first a small bottle

half-filled with a pale yellow liquid, and next a small case of

morocco leather. From the case she took a hypodermic syringe and its

needle, and screwed the two parts together.

"Is she ready?" Betty asked as she removed the stopper from the

bottle.

"Quite, Mademoiselle," answered Francine. She began with a giggle,

but she looked at the prisoner as she spoke and she ended with a

startled gasp. For Ann was looking straight at her with the

strangest, disconcerting stare. It was impossible to say whether she

knew Francine or knowing her would not admit her knowledge. But her

gaze never faltered, it was actually terrifying by its fixity, and in

a sharp, hysterical voice Francine suddenly cried out:

"Turn your eyes away from me, will you?" and she added with a shiver:

"It's horrible, Mademoiselle! It's like a dead person watching you

as you move about the room."

Betty turned curiously towards the divan and Ann's eyes wandered off

to her. It seemed as though it needed just that interchange of

glances to awaken her. For as Betty resumed her work of filling the

hypodermic syringe from the bottle, a look of perplexity crept into

Ann Upcott's face. She tried to sit up, and finding that she could

not, tore at the cords which bound her wrists. Her feet kicked upon

the divan. A moan of pain broke from her lips, and with that

consciousness returned to her.

"Betty!" she whispered, and Betty turned with the needle ready in her

hand. She did not speak, but her face spoke for her. Her upper lip

was drawn back a little from her teeth, and there was a look in her

great eyes which appalled Jim Frobisher outside the door. Once

before he had seen just that look--when Betty was lying on Mrs.

Harlowe's bed for Hanaud's experiment and he had lingered in the

treasure-room with Ann Upcott. It had been inscrutable to him then,

but it was as plain as print now. It meant murder. And so Ann

Upcott understood it. Helpless as she was, she shrank back upon the

divan; in a panic she spoke with faltering lips and her eyes fixed

upon Betty with a dreadful fascination.

"Betty! You had me taken and brought here! You sent me to Madame Le

Vay's--on purpose. Oh! The letter, then! The anonymous

letter!"--and a new light broke in upon Ann's mind, a new terror

shook her. "You wrote it! Betty, you! You--the Scourge!"

She sank back and again struggled vainly with her bonds. Betty rose

from her chair and crossed the room towards her, the needle shining

bright in her hand. Her hapless prisoner saw it.

"What's that?" she cried, and she screamed aloud. The extremity of

her horror lent to her an unnatural strength. Somehow she dragged

herself up and got her feet to the ground. Somehow she stood

upright, swaying as she stood.

"You are going to----" she began, and broke off. "Oh, no! You

couldn't! You couldn't!"

Betty put out a hand and laid it on Ann's shoulder and held her so

for a moment, savouring her vengeance.

"Whose face was it bending so close down over yours in the darkness?"

she asked in a soft and dreadful voice. "Whose face, Ann? Guess!"

She shook her swaying prisoner with a gentleness as dreadful as her

quiet voice. "You talk too much. Your tongue's dangerous, Ann. You

are too curious, Ann! What were you doing in the treasure-room

yesterday evening with your watch in your hand? Eh? Can't you

answer, you pretty fool?" Then Betty's voice changed. It remained

low and quiet, but hatred crept into it, a deep, whole-hearted hatred.

"You have been interfering with me too, haven't you, Ann? Oh, we

both understand very well!" And Hanaud's hand tightened upon

Frobisher's shoulder. Here was the real key and explanation of

Betty's hatred. Ann Upcott knew too much, was getting to know more,

might at any moment light upon the whole truth. Yes! Ann Upcott's

disappearance would look like a panic-stricken flight, would have the

effect of a confession--no doubt! But above all these

considerations, paramount in Betty Harlowe's mind was the resolve at

once to punish and rid herself of a rival.

"All this week, you have been thrusting yourself in my way!" she

said. "And here's your reward for it, Ann. Yes. I had you bound

hand and foot and brought here. The water-lily!" She looked her

victim over as she stood in her delicate bright frock, her white silk

stockings and satin slippers, swaying in terror. "Fifteen minutes,

Ann! That fool of a detective was right! Fifteen minutes! That's

all the time the arrow-poison takes!"

Ann's eyes opened wide. The blood rushed into her white face and

ebbed, leaving it whiter than it was before.

"Arrow-poison!" she cried. "Betty! It was you, then! Oh!" she

would have fallen forward, but Betty Harlowe pushed her shoulder

gently and she fell back upon the divan. That Betty had been guilty

of that last infamy--the murder of her benefactress--not until this

moment had Ann Upcott for one moment suspected. It was clear to her,

too, that there was not the slightest hope for her. She burst

suddenly into a storm of tears.

Betty Harlowe sat down on the divan beside her and watched her

closely and curiously with a devilish enjoyment. The sound of the

girl's sobbing was music in her ears. She would not let it flag.

"You shall lie here in the dark all night, Ann, and alone," she said

in a low voice, bending over her, "To-morrow Espinosa will put you

under one of the stone flags in the kitchen. But to-night you shall

lie just as you are. Come!"

She bent over Ann Upcott, gathering the flesh of her arm with one

hand and advancing the needle with the other; and a piercing scream

burst from Francine Rollard.

"Look!" she cried, and she pointed to the door. It was open and

Hanaud stood upon the threshold.

Betty looked up at the cry and the blood receded from her face. She

sat like an image of wax, staring at the open doorway, and a moment

afterwards with a gesture swift as lightning she drove the needle

into the flesh of her own arm and emptied it.

Frobisher with a cry of horror started forward to prevent her, but

Hanaud roughly thrust him back.

"I warned you, Monsieur, not to interfere," he said with a savage

note in his voice, which Jim had not heard before; and Betty Harlowe

dropped the needle on to the couch, whence it rolled to the floor.

She sprang up now to her full height, her heels together, her arms

outstretched from her sides.

"Fifteen minutes, Monsieur Hanaud," she cried with bravado. "I am

safe from you."

Hanaud laughed and wagged his forefinger contemptuously in her face.

"Coloured water, Mademoiselle, doesn't kill."

Betty swayed upon her feet and steadied herself.

"Bluff, Monsieur Hanaud!" she said.

"We shall see."

The confidence of his tone convinced her. She flashed across the

room to her writing-table. Swift as she was, Hanaud met her there.

"Ah, no!" he cried. "That's quite a different thing!" He seized her

wrists. "Moreau!" he called, with a nod towards Francine. "And you,

Monsieur Frobisher, will you release that young lady, if you please!"

Moreau dragged Francine Rollard from the room and locked her safely

away. Jim seized upon the big scissors and cut the cords about Ann's

wrists and ankles, and unwound them. He was aware that Hanaud had

flung the chair from the writing-table into an open space, that Betty

was struggling and then was still, that Hanaud had forced her into

the chair and snatched up one of the cords which Frobisher had

dropped upon the floor. When he had finished his work, he saw that

Betty was sitting with her hands in handcuffs and her ankles tied to

one of the legs of the chair; and Hanaud was staunching with his

handkerchief a wound in his hand which bled. Betty had bitten him

like a wild animal caught in a trap.

"Yes, you warned me, Mademoiselle, the first morning I met you,"

Hanaud said with a savage irony, "that you didn't wear a wrist-watch,

because you hated things on your wrists. My apologies! I had

forgotten!"

He went back to the writing-table and thrust his hand into the

drawer. He drew out a small cardboard box and removed the lid.

"Five!" he said. "Yes! Five!"

He carried the box across the room to Frobisher, who was standing

against the wall with a face like death.

"Look!"

There were five white tablets in the box.

"We know where the sixth is. Or, rather, we know where it was. For

I had it analysed to-day. Cyanide of potassium, my friend! Crunch

one of them between your teeth and--fifteen minutes? Not a bit of

it! A fraction of a second! That's all!"

Frobisher leaned forward and whispered in Hanaud's ear. "Leave them

within her reach!"

His first instinctive thought had been to hinder Betty from

destroying herself. Now he prayed that she might, and with so

desperate a longing that a deep pity softened Hanaud's eyes.

"I must not, Monsieur," he said gently. He turned to Moreau. "There

is a cab waiting at the corner of the Maison Grenelle," and Moreau

went in search of it. Hanaud went over to Ann Upcott, who was

sitting upon the divan her head bowed, her body shivering. Every now

and then she handled and eased one of her tortured wrists.

"Mademoiselle," he said, standing in front of her, "I owe you an

explanation and an apology. I never from the beginning--no, not for

one moment--believed that you were guilty of the murder of Madame

Harlowe. I was sure that you had never touched the necklace of pink

pearls--oh, at once I was sure, long before I found it. I believed

every word of the story you told us in the garden. But none of this

dared I shew you. For only by pretending that I was convinced of

your guilt, could I protect you during this last week in the Maison

Grenelle."

"Thank you, Monsieur," she replied with a wan effort at a smile.

"But, for to-night, I owe you an apology," he continued. "I make it

with shame. That you were to be brought back here to the tender

mercies of Mademoiselle Betty, I hadn't a doubt. And I was here to

make sure you should be spared them. But I have never in my life had

a more difficult case to deal with, so clear a conviction in my own

mind, so little proof to put before a court. I had to have the

evidence which I was certain to find in this room to-night. But I

ask you to believe me that if I had imagined for a moment the cruelty

with which you were to be handled, I should have sacrificed this

evidence. I beg you to forgive me."

Ann Upcott held out her hand.

"Monsieur Hanaud," she replied simply, "but for you I should not be

now alive. I should be lying here in the dark and alone, as it was

promised to me, waiting for Espinosa--and his spade." Her voice

broke and she shuddered violently so that the divan shook on which

she sat.

"You must forget these miseries," he said gently. "You have youth,

as I told you once before. A little time and----"

The return of Nicolas Moreau interrupted him; and with Moreau came a

couple of gendarmes and Girardot the Commissary.

"You have Francine Rollard?" Hanaud asked.

"You can hear her," Moreau returned dryly.

In the corridor a commotion arose, the scuffling of feet and a

woman's voice screaming abuse. It died away.

"Mademoiselle here will not give you so much trouble," said Hanaud.

Betty was sitting huddled in her chair, her face averted and sullen,

her lips muttering inaudible words. She had not once looked at Jim

Frobisher since he had entered the room; nor did she now.

Moreau stooped and untied her ankles and a big gendarme raised her

up. But her knees failed beneath her; she could not stand; her

strength and her spirit had left her. The gendarme picked her up as

if she had been a child; and as he moved to the door, Jim Frobisher

planted himself in front of him.

"Stop!" he cried, and his voice was strong and resonant. "Monsieur

Hanaud, you have said just now that you believed every word of

Mademoiselle Ann's story."

"It is true."

"You believe then that Madame Harlowe was murdered at half-past ten

on the night of the 27th of April. And at half-past ten Mademoiselle

here was at Monsieur de Pouillac's ball! You will set her free."

Hanaud did not argue the point.

"And what of to-night?" he asked. "Stand aside, if you please!"

Jim held his ground for a moment or two, and then drew aside. He

stood with his eyes closed, and such a look of misery upon his face

as Betty was carried out that Hanaud attempted some clumsy word of

condolence:

"This has been a bitter experience for you, Monsieur Frobisher," he

began.

"Would that you had taken me into your confidence at the first!" Jim

cried volubly.

"Would you have believed me if I had?" asked Hanaud, and Jim was

silent. "As it was, Monsieur Frobisher, I took a grave risk which I

know now I had not the right to take and I told you more than you

think."

He turned away towards Moreau.

"Lock the courtyard doors and the door of the house after they have

gone and bring the keys here to me."

Girardot had made a bundle of the solution, the hypodermic syringe,

the tablets of cyanide, and the pieces of cord.

"There is something here of importance," Hanaud observed and,

stooping at the writing-table, he picked up a square, flat-topped

black case. "You will recognise this," he remarked to Jim as he

handed it to Girardot. It was the case of a Corona typewriting

machine; and from its weight, the machine itself was clearly within

the case.

"Yes," Hanaud explained, as the door closed upon the Commissary.

"This pretty room is the factory where all those abominable letters

were prepared. Here the information was filed away for use; here the

letters were typed; from here they were issued."

"Blackmailing letters!" cried Jim. "Letters demanding money!"

"Some of them," answered Hanaud.

"But Betty Harlowe had money. All that she needed, and more if she

chose to ask for it."

"All that she needed? No," answered Hanaud with a shake of the head.

"The blackmailer never has enough money. For no one is so

blackmailed."

A sudden and irrational fury seized upon Frobisher. They had agreed,

he and Hanaud, that there was a gang involved in all these crimes.

It might be that Betty was of them, yes, even led them, but were they

all to go scot-free?

"There are others," he exclaimed. "The man who rode this

motor-cycle----"

"Young Espinosa," replied Hanaud. "Did you notice his accent when

you stopped at the fork of the roads in the Val Terzon? He did not

mount his cycle again. No!"

"And the man who carried in the--the sack?"

"Maurice Thevenet," said Hanaud. "That promising young novice. He

is now at the Depot. He will never get that good word from me which

was to unlock Paris for him."

"And Espinosa himself--who was to come here to-morrow----" he stopped

abruptly with his eyes on Ann.

"And who murdered Jean Cladel, eh?" Hanaud went on. "A fool that

fellow! Why use the Catalan's knife in the Catalan's way?" Hanaud

looked at his watch. "It is over. No doubt Espinosa is under lock

and key by now. And there are others, Monsieur, of whom you have

never heard. The net has been cast wide to-night. Have no fear of

that!"

Moreau returned with the keys and handed them to Hanaud. Hanaud put

them into a pocket and went over to Ann Upcott.

"Mademoiselle, I shall not trouble you with any questions to-night.

To-morrow you will tell me why you went to Madame Le Vay's ball. It

was given out that you meant to run away. That, of course, was not

true. You shall give me the real reason to-morrow and an account of

what happened to you there."

Ann shivered at the memories of that night, but she answered quietly.

"Yes. I will tell you everything."

"Good. Then we can go," said Hanaud cheerfully.

"Go?" Ann Upcott asked in wonderment. "But you have had us all

locked in."

Hanaud laughed. He had a little surprise to spring on the girl, and

he loved surprises so long as they were of his own contriving.

"Monsieur Frobisher, I think, must have guessed the truth. This

house, Mademoiselle, the Hôtel de Brebizart is very close, as the

crow flies, to the Maison Grenelle. There is one row of houses, the

houses of the street of Charles-Robert, between. It was built by

Etienne Bouchart de Grenelle, President of the Parliament during the

reign of Louis the Fifteenth, a very dignified and important figure;

and he built it, Mademoiselle--this is the point--at the same time

that he built the Maison Grenelle. Having built it, he installed in

it a joyous lady of the province from which it takes its name--Madame

de Brebizart. There was no scandal. For the President never came

visiting Madame de Brebizart. And for the best of reasons. Between

this house and the Maison Grenelle he had constructed a secret

passage in that age of secret passages."

Frobisher was startled. Hanaud had given credit to him for an

astuteness which he did not possess. He had been occupied heart and

brain by the events of the evening, so rapidly had they followed one

upon the other, so little time had they allowed for speculations.

"How in the world did you discover this?" he asked.

"You shall know in due time. For the moment let us content ourselves

with the facts," Hanaud continued. "After the death of Etienne de

Grenelle, at some period or another the secret of this passage was

lost. It is clear, too, I think that it fell into disrepair and

became blocked. At all events at the end of the eighteenth century,

the Hôtel de Brebizart passed into other hands than those of the

owner of the Maison Grenelle. Simon Harlowe, however, discovered the

secret. He bought back the Hôtel de Brebizart, restored the passage

and put it to the same use as old Etienne de Grenelle had done. For

here Madame Raviart came to live during the years before the death of

her husband set her free to marry Simon. There! My little lecture

is over. Let us go!"

He bowed low to Ann like a lecturer to his audience and unlatched the

double doors of the big buhl cabinet in the recess of the wall. A

cry of surprise broke from Ann, who had risen unsteadily to her feet.

The cabinet was quite empty. There was not so much as a shelf, and

all could see that the floor of it was tilted up against one end and

that a flight of steps ran downwards in the thickness of the wall.

"Come," said Hanaud, producing his electric torch. "Will you take

this, Monsieur Frobisher, and go first with Mademoiselle. I will

turn out the lights and follow."

But Ann with a little frown upon her forehead drew sharply back. She

put a hand to Hanaud's sleeve and steadied herself by it. "I will

come with you," she said. "I am not very steady on my legs."

She laughed her action off but both men understood it. Jim Frobisher

had thought her guilty--guilty of theft and murder. She shrank from

him to the man who had had no doubt that she was innocent. And even

that was not all. She was wounded by Jim's distrust more deeply than

any one else could have wounded her. Frobisher inclined his head in

acknowledgment and, pressing the button of the torch, descended five

or six of the narrow steps. Moreau followed him.

"You are ready, Mademoiselle? So!" said Hanaud.

He put an arm about her to steady her and pressed up a switch by the

open doors of the cabinet. The room was plunged in darkness. Guided

by the beam of light, they followed Frobisher on to the steps.

Hanaud closed the doors of the cabinet and fastened them together

with the bolts.

"Forward," he cried, "and you, Mademoiselle, be careful of your heels

on these stone steps."

When his head was just below the level of the first step he called

upon Frobisher to halt and raise the torch. Then he slid the floor

board of the cabinet back into its place. Beneath this a trap-door

hung downwards. Hanaud raised it and bolted it in place.

"We can go on."

Ten more steps brought them to a tiny vaulted hall. From that a

passage, bricked and paved, led into darkness. Frobisher led the way

along the passage until the foot of another flight of steps was

reached.

"Where do these steps lead, my friend?" Hanaud asked of Frobisher,

his voice sounding with a strange hollowness in that tunnel. "You

shall tell me."

Jim, with memories of that night when he and Ann and Betty had sat in

the dark of the perfumed garden and Ann's eyes had searched this way

and that amidst the gloom of the sycamores, answered promptly:

"Into the garden of the Maison Grenelle."

Hanaud chuckled.

"And you, Mademoiselle, what do you say?"

Ann's face clouded over.

"I know now," she said gravely. Then she shivered and drew her cloak

slowly about her shoulders. "Let us go up and see!"

Hanaud took the lead. He lowered a trap-door at the top of the

steps, touched a spring and slid back a panel.

"Wait," said he, and he sprang out and turned on a light.

Ann Upcott, Jim Frobisher and Moreau climbed out of Simon Harlowe's

Sedan chair into the treasure room.

CHAPTER TWENTY-THREE: _The Truth About the Clock on the Marquetry

Cabinet_

To the amazement of them all Moreau began to laugh. Up till now he

had been alert, competent and without expression. Stolidity had been

the mark of him. And now he laughed in great gusts, holding his

sides and then wringing his hands, as though the humour of things was

altogether unbearable. Once or twice he tried to speak, but laughter

leapt upon the words and drowned them.

"What in the world is the matter with you, Nicolas?" Hanaud asked.

"But I beg your pardon," Moreau stammered, and again merriment seized

and mastered him. At last two intelligible words were heard. "We,

Girardot," he cried, settling an imaginary pair of glasses on the

bridge of his nose, and went off into a fit. Gradually the reason of

his paroxysms was explained in broken phrases.

"We, Girardot!--We fix the seals upon the doors--And all the time

there is a way in and out under our nose! These rooms must not be

disturbed--No! The great Monsieur Hanaud is coming from Paris to

look at them. So we seal them tight, we, Girardot. My God! but we,

Girardot look the fool! So careful and pompous with our linen bands!

We, Girardot shall make the laughter at the Assize Court! Yes, yes,

yes! I think, we, Girardot shall hand in our resignation before the

trial is over?"

Perhaps Moreau's humour was a little too professional for his

audience. Perhaps, too, the circumstances of that night had dulled

their appreciation; certainly Moreau had all the laughter to himself.

Jim Frobisher was driven to the little Louis Quinze clock upon the

marquetry cabinet. He never could for a moment forget it. So much

hung for Betty Harlowe upon its existence. Whatever wild words she

might have used to-night, there was the incontrovertible testimony of

the clock to prove that she had had no hand whatever in the murder of

Mrs. Harlowe. He drew his own watch from his pocket and compared it

with the clock.

"It is exact to the minute," he declared with a little accent of

triumph. "It is now twenty-three minutes past one----" and suddenly

Hanaud was at his side with a curious air of alertness.

"Is it so?" he asked, and he too made sure by a comparison with his

own watch that Frobisher's statement was correct. "Yes.

Twenty-three minutes past one. That is very fortunate."

He called Ann Upcott and Moreau to him and they all now stood grouped

about the cabinet.

"The key to the mystery about this clock," he remarked, "is to be

found in the words which Mademoiselle Ann used, when the seals were

removed from the doors and she saw this clock again, in the light of

day. She was perplexed. Isn't that so, Mademoiselle?"

"Yes," Ann returned. "It seemed to me--it seems to me still--that

the clock was somehow placed higher than it actually is----"

"Exactly. Let us put it to the test!"

He looked at the clock and saw that the hands now reached twenty-six

minutes past one.

"I will ask you all to go out of this room and wait in the hall in

the dark. For it was in the dark, you will remember, that

Mademoiselle descended the stairs. I shall turn the lights out here

and call you in. When I do, Mademoiselle will switch the lights on

and off swiftly, just as she did it on the night of the 27th of

April. Then I think all will be clear to you."

He crossed to the door leading into the hall, and found it locked

with the key upon the inside.

"Of course," he said, "when the passage is used to the Hôtel de

Brebizart, this door would be locked."

He turned the key and drew the door towards him. The hall gaped

before them black and silent. Hanaud stood aside.

"If you please!"

Moreau and Frobisher went out; Ann Upcott hesitated and cast a look

of appeal towards Hanaud. Her perplexities were to be set at rest.

She did not doubt that. This man had saved her from death when it

seemed that nothing could save her. Her trust in him was absolute.

But her perplexities were unimportant. Some stroke was to be

delivered upon Betty Harlowe from which there could be no recovery.

Ann Upcott was not a good hater of Betty's stamp. She shrank from

the thought that it was to be her hand which would deliver that

stroke.

"Courage, Mademoiselle!"

Hanaud exhorted her with a friendly smile and Ann joined the others

in the dark hall. Hanaud closed the door upon them and returned to

the clock. It was twenty-eight minutes past one.

"I have two minutes," he said to himself. "That will just do if I am

quick."

Outside the three witnesses waited in the darkness. One of the three

shivered suddenly so that her teeth rattled in her mouth.

"Ann," Jim Frobisher whispered and he put his hand within her arm.

Ann Upcott had come to the end of her strength. She clung to his

hand spasmodically.

"Jim!" she answered under her breath. "Oh, but you were cruel to me!"

Hanaud's voice called to them from within the room.

"Come!"

Ann stepped forward, felt for and found the handle. She threw open

the door with a nervous violence. The treasure-room was pitch dark

like the hall. Ann stepped through the doorway and her fingers

reached for the switch.

"Now," she warned them in a voice which shook.

Suddenly the treasure-room blazed with light; as suddenly it was

black again; and in the darkness rose a clamour of voices.

"Half-past ten! I saw the hour!" cried Jim.

"And again the clock was higher!" exclaimed Ann.

"That is true," Moreau agreed.

Hanaud's voice, from the far corner of the room, joined in.

"Is that exactly what you saw, Mademoiselle, on the night of the

twenty-seventh?"

"Exactly, Monsieur."

"Then turn on the lights again and know the truth!"

The injunction was uttered in tones so grave that it sounded like a

knell. For a second or two Ann's fingers refused their service.

Once more the conviction forced itself into her mind. Some

irretrievable calamity waited upon the movement of her hand.

"Courage, Mademoiselle!"

Again the lights shone, and this time they remained burning. The

three witnesses advanced into the room, and as they looked again,

from close at hand and with a longer gaze, a cry of surprise broke

from all of them.

There was no clock upon the marquetry cabinet at all.

But high above it in the long mirror before which it stood there was

the reflection of a clock, its white face so clear and bright that

even now it was difficult to disbelieve that this was the clock

itself. And the position of the hands gave the hour as precisely

half-past ten.

"Now turn about and see!" said Hanaud.

The clock itself stood upon the shelf of the Adam mantelpiece and

there staring at them, the true hour was marked. It was exactly

half-past one; the long minute hand pointing to six, the shorter hour

hand on the right-hand side of the figure twelve, half-way between

the one and the two. With a simultaneous movement they all turned

again to the mirror; and the mystery was explained. The shorter

hour-hand seen in the mirror was on the left-hand side of the figure

twelve, and just where it would have been if the hour had been

half-past ten and the clock actually where its reflection was. The

figures on the dial were reversed and difficult at a first glance to

read.

"You see," Hanaud explained, "it is the law of nature to save itself

from effort even in the smallest things. We live with clocks and

watches. They are as customary as our daily bread. And with the

instinct to save ourselves from effort, we take our time from the

position of the hands. We take the actual figures of the hours for

granted. Mademoiselle comes out of the dark. In the one swift flash

of light she sees the hands upon the clock's face. Half-past ten!

She herself, you will remember, Monsieur Frobisher, was surprised

that the hour was so early. She was cold, as though she had slept

long in her arm-chair. She had the impression that she had slept

long. And Mademoiselle was right. For the time was half-past one,

and Betty Harlowe had been twenty minutes home from Monsieur de

Pouillac's ball."

Hanaud ended with a note of triumph in his voice which exasperated

Frobisher.

"Aren't you going a little too fast?" he asked. "When the seals were

removed and we entered this room for the first time, the clock was

not upon the mantelshelf but upon the marquetry cabinet."

Hanaud nodded.

"Mademoiselle Upcott told us her story before luncheon. We entered

this room after luncheon. During the luncheon hours the position of

the clock was changed." He pointed to the Sedan chair. "You know

now with what ease that could be done."

"'Could, could!'" Frobisher repeated impatiently. "It doesn't follow

that it was done."

"That is true," Hanaud replied. "So I will answer now one of the

questions in your memorandum. What was it that I saw from the top of

the Terrace Tower? I saw the smoke rising from this chimney into the

air. Oh, Monsieur, I had paid attention to this house, its windows,

and its doors, and its chimney-stacks. And there at midday, in all

the warmth of late May, the smoke was rising from the chimney of the

sealed room. There was an entrance then of which we knew nothing!

And somebody had just made use of it. Who? Ask yourself that! Who

went straight out from the Maison Grenelle the moment I had gone, and

went alone? That clock had to be changed. Apparently some letters

also had to be burnt."

Jim hardly heard the last sentence. The clock still occupied his

thoughts. His great argument had been riddled; his one dream of

establishing Betty's innocence in despite of every presumption and

fact which could be brought against her had been dispelled. He

dropped on to a chair.

"You understood it all so quickly," he said with bitterness.

"Oh, I was not quick!" Hanaud answered. "Ascribe to me no gifts out

of the ordinary run, Monsieur. I am trained--that is all. I have

been my twenty minutes in the bull-ring. Listen how it came about!"

He looked at Frobisher with a comical smile. "It is a pity our eager

young friend, Maurice Thevenet, is not here to profit by the lesson.

First of all, then! I knew that Mademoiselle Betty was here doing

something of great importance. It may be only burning those letters

in the hearth. It may be more. I must wait and see. Good! There,

standing before the mirror, Mademoiselle Ann makes her little remark

that the clock seemed higher. Do I understand yet? No, no! But I

am interested. Then I notice a curious thing, a beautiful specimen

of Benvenuto Cellini's work set up high and flat on that mantelshelf

where no one can see it. So I take it down, and I carry it to the

window, and I admire it very much and I carry it back to the

mantelshelf; and then I notice four little marks upon the wood which

had been concealed by the flat case of the jewel; and those four

little marks are just the marks which the feet of that very pretty

Louis Quinze clock might have made, had it stood regularly there--in

its natural place. Yes, and the top of that marquetry cabinet so

much lower than the mantelshelf is too the natural place for the

Cellini jewel. Every one can see it there. So I say to myself: 'My

good Hanaud, this young lady has been rearranging her ornaments.'

But do I guess why? No, my friend. I told you once, and I tell you

again very humbly, that we are the servants of Chance. Chance is a

good mistress if her servants do not go to sleep; and she treated me

well that afternoon. See! I am standing in the hall, in great

trouble about this case. For nothing leads me anywhere. There is a

big old-fashioned barometer like a frying-pan on the wall behind me

and a mirror on the opposite wall in front of me. I raise my eyes

from the floor and by chance I see in the mirror the barometer behind

me. By chance my attention is arrested. For I see that the

indicator in the barometer points to stormy weather--which is

ridiculous. I turn me about so. It is to fine weather that the

indicator points. And in a flash I see. I look at the position of

the hand without looking at the letters. If I look the barometer in

the face the hand points to the fair weather. If I turn my back and

look into the mirror the hand points to the stormy weather. Now

indeed I have it! I run into the treasure-room. I lock the door,

for I do not wish to be caught. I do not move the clock. No, no,

for nothing in the world will I move that clock. But I take out my

watch. I face the mirror. I hold my watch facing the mirror, I open

the glass and I move the hands until in the mirror they seem to mark

half-past ten. Then I look at my watch itself. It is half-past one.

So now I know! Do I want more proof? Monsieur, I get it. For as I

unlock the door and open it again, there is Mademoiselle Betty face

to face with me! That young girl! Even though already I suspect her

I get a shock, I can tell you. The good God knows that I am hardened

enough against surprises. But for a moment the mask had slipped from

her face. I felt a trickle of ice down my spine. For out of her

beautiful great eyes murder looked."

He stood held in a spell by the memory of that fierce look. "Ugh,"

he grunted; and he shook himself like a great dog coming up out of

the water.

"But you are talking too much, Monsieur Frobisher," he cried in a

different voice, "and you are keeping Mademoiselle from her bed,

where she should have been an hour ago. Come!"

He drove his companions out into the hall, turned on the lights,

locked the door of the treasure-room and pocketed the key.

"Mademoiselle, we will leave these lights burning," he said gently to

Ann, "and Moreau will keep watch in the house. You have nothing to

fear. He will not be far from your door. Good night."

Ann gave him her hand with a wan smile.

"I shall thank you to-morrow," she said, and she mounted the stairs

slowly, her feet dragging, her body swaying with her fatigue.

Hanaud watched her go. Then he turned to Frobisher with a whimsical

smile.

"What a pity!" he said. "You--she! No? After all, perhaps----" and

he broke off hurriedly. Frobisher was growing red and beginning to

look "proper"; and the last thing which Hanaud wished to do was to

offend him in this particular.

"I make my apologies," he said. "I am impertinent and a gossip. If

I err, it is because I wish you very well. You understand that?

Good! Then a further proof. To-morrow Mademoiselle will tell us

what happened to her to-night, how she came to go to the house of

Madame Le Vay--everything. I wish you to be present. You shall know

everything. I shall tell you myself step by step, how my conclusions

were reached. All your questions shall be answered. I shall give

you every help, every opportunity. I shall see to it that you are

not even called as a witness of what you have seen to-night. And

when all is over, Monsieur, you will see with me that whatever there

may be of pain and distress, the Law must take its course."

It was a new Hanaud whom Frobisher was contemplating now. The

tricks, the Gasconnades, the buffooneries had gone. He did not even

triumph. A dignity shone out of the man like a strong light, and

with it he was gentle and considerate.

"Good night, Monsieur!" he said, and bowed; and Jim on an impulse

thrust out his hand.

"Good night!" he returned.

Hanaud took it with a smile of recognition and went away.

Jim Frobisher locked the front door and with a sense of desolation

turned back to the hall. He heard the big iron gates swing to. They

had been left open, of course, he recognised, in the usual way when

one of the household was going to be late. Yes, everything had been

planned with the care of a commander planning a battle. Here in this

house, the servants were all tucked up in their beds. But for

Hanaud, Betty Harlowe might at this very moment have been stealing up

these stairs noiselessly to her own room, her dreadful work

accomplished. The servants would have waked to-morrow to the

knowledge that Ann Upcott had fled rather than face a trial.

Sometime in the evening, Espinosa would have called, would have been

received in the treasure-room, would have found the spade waiting for

him in the great stone-vaulted kitchen of the Hôtel de Brebizart.

Oh, yes, all dangers had been foreseen--except Hanaud. Nay, even he

in a measure had been foreseen! For a panic-stricken telegram had

reached Frobisher and Haslitt before Hanaud had started upon his work.

"I shall be on the stairs, Monsieur, below Mademoiselle's door, if

you should want me," said Moreau.

Jim Frobisher roused himself from his reflections.

"Thank you," he answered, and he went up the stairs to his room. A

lot of use to Betty that telegram had been, he reflected bitterly!

"Where was she to-night?" he asked, and shut up his mind against the

question.

He was to know that it was precisely that panic-stricken telegram and

nothing else which had brought Betty Harlowe's plans crashing about

her ears.
