CHAPTER L

THE SILVER SHIELD

The Bishop sat at the round table in the centre of the banqueting hall,

sipping water from his purple goblet while the Knight dined.

They were not alone. Lay-brethren, with sandalled feet, moved

noiselessly to and fro; and Brother Philip stood immovable behind the

Reverend Father's chair.

The Bishop discoursed pleasantly of many things, watching Hugh the

while, and blessing the efficacy of the bath. It had, undoubtedly,

cleansed away much beside travel-stains.

The thunder-cloud had lifted from the Knight's brow; his eyes, though

tired, were no longer sombre; his manner was more than usually

courteous and deferential, as if to atone for the defiant brusquerie of

his first appearance.

He listened in absolute silence to the Bishop's gentle flow of

conversation; but this was a trait the Bishop had observed in him

before; and, after all, a lapse into silence could be easily understood

when a man had travelled far, on meagre fare, and found himself seated

at a well-spread board.

Yet the Knight ate but sparingly of the good cheer, so lavishly

provided; and the famous Italian wine, he scarce touched at all.

The meal over, the Bishop dismissed Brother Philip and the attendant

monks, and, rising, went to his chair near the hearth, motioning the

Knight to the one opposite.

Thus they found themselves seated again as they had sat on the night of

the arrival of the Pope's messenger; save that now no fire burned upon

the hearth; no candles were lighted on the table. Instead, the summer

sunshine poured in through open casements.

"Well, my dear Hugh," said the Bishop, "suppose you now tell me the

reason which brings you hither. It must surely be a matter of grave

importance which could cause so devoted a lover and husband to leave

his bride, and go a five days' journey from her, within two weeks of

the bridal day."

"I have come, my lord," said the Knight, speaking slowly and with

evident effort, "to learn from your lips the entire truth concerning

that vision which caused the Prioress of the White Ladies to hold

herself free to renounce her vows, leave her Nunnery, and give herself

in marriage where she had been betrothed before entering the Cloister."

"Tut!" said the Bishop. "The White Ladies have no Prioress. Mother

Sub-Prioress doth exercise the functions of that office until such time

as the Prior and myself shall make a fresh appointment. We are not

here to talk of prioresses, my son, but of that most noble and gracious

lady who, by the blessing of God and our Lady's especial favour, is now

your wife. See to it that you continue to deserve your great good

fortune."

The Knight made no protest at the mention of our Lady; but his left

hand moved to the medallion hanging by a gold chain from his neck,

covered it and clasped it firmly.

The Bishop paused; but finding that the Knight had relapsed into

silence, continued:

"So you wish the entire history of the inspired devotion of the old

lay-sister, Mary Antony--may God rest her soul." Both men crossed

themselves devoutly, as the Bishop named the Dead. "Shall I give it

you now, my son, or will you wait until the morrow, when a good night's

rest shall fit you better to enjoy the recital?"

"My lord," said Hugh, "ere this sun sets, I hope to be many miles on my

homeward way."

"In that case," said the Bishop, "I must tell you this moving story,

without further delay."

So, beginning with her custom of counting the White Ladies by means of

the dried peas, the Bishop gave the Knight the whole history of Mary

Antony's share in the happenings in the Nunnery on the day of his

intrusion, and those which followed; laying especial stress on her

devotion to Mora, and her constant prayers to our Lady to sharpen her

old wits.

The Bishop had undoubtedly intended to introduce into the recital

somewhat more of mysticism and sublimity than the actual facts

warranted. But once launched thereon, his sense of humour could not be

denied its full enjoyment in this first telling of the entire tale.

Full justice he did to the pathos, but he also shook with mirth over

the ludicrous. As he quoted Mary Antony, the old lay-sister's odd

manner and movements could be seen; her mumbling lips, and cunning

wink. And here was Mother Sub-Prioress, ferret-faced and peering; and

here Sister Mary Rebecca, long-nosed, flat-footed, eager to scent out

and denounce wrong doing. And at last the Bishop told of his talk with

Mora in the arbour of golden roses; and lo, there was Mora, devout,

adoring, wholly believing. "Thou hast hid these things from the wise

and prudent and hast revealed them unto babes"; and here, the Bishop

himself, half amused, half incredulous: "An ancient babe! Truly, a

most wise and prudent babe." Then the scene outside the Prioress's

cell when the Bishop unlocked the door; the full confession and the

touching death of old Mary Antony.

To it all the Knight listened silently, shading his face with his right

hand.

"Therefore, my son," concluded Symon of Worcester, "when on a sudden I

remembered our conversation on the lawn, and that I had told you of my

belief that the old lay-sister knew of your visit to the Convent and

had seen you in Mora's cell, I hastened to send you a warning, lest you

should, unwittingly, mention this fact to Mora, and raise a doubt in

her mind concerning the genuineness of the vision, thus destroying her

peace, and threatening her happiness and your own. Hath she already

told you of the vision?"

Still shielding his face the Knight spoke, very low:

"The evening before the messenger arrived, bringing your letter, my

lord, Mora told me of the vision."

"Said you aught concerning my words to you?"

"So soon as she mentioned the name of Mary Antony, I said that I seemed

to recall that you, my lord, had told me she alone knew of my visit to

the Convent. But Mora at once said nay, that it was she herself who

had told me so, even while I stood undiscovered in her cell; but that

afterward the lay-sister had confessed herself mistaken. This seemed

to me to explain the matter, therefore I said no more; nor did I, for a

moment, doubt the truth and wonder of the vision."

"For that, the saints be praised," said the Bishop. "Then no harm is

done. You and I, alone, know the entire story; and you and I, who

would safeguard Mora's happiness with our lives, must see to it that

she never has cause for misgivings."

Hugh d'Argent lifted his head, and looked full at the Bishop.

"My lord," he said, "had there been no vision, no message from our

Lady, no placing by her of Mora's hand in mine, think you she would

have left the Nunnery and come to me?"

"Nay, dear lad, that I know she would not. On that very morning, as I

told you, she set her foot upon the Pope's mandate, and would accept no

absolving from her vows. Naught would suffice, said she, but a direct

vision and revelation from our Lady herself."

"But," said the Knight, slowly, "was there a vision, my lord? Was

there a revelation? Was there a spoken message or a given sign?"

The Bishop met the earnest eyes, full of a deep searching. He stirred

uneasily; then smiled, waving a deprecatory hand.

"Between ourselves, my dear Hugh--though even so, it is not well to be

too explicit--between ourselves of course nothing--well--miraculous

happened, beyond the fact that our Lady most certainly sharpened the

wits of old Antony. Therefore is it, that you undoubtedly owe your

wife to those same wits, and may praise our Lady for sharpening them."

Then it was that the Knight rose to his feet.

"And I refuse," he said, "to owe my wife to sacrilege, fraud, and

falsehood."

The Bishop leaned forward, gripping with both hands the arms of his

chair. His face was absolutely colourless; but his eyes, like blue

steel, seemed to transfix the Knight, who could not withdraw his regard

from those keen points of light.

The Bishop's whisper, when at length he spoke, was more alarming than

if he had shouted.

"Fool!" he said. "Ungrateful, unspeakable fool! What mean you by such

words?"

"Call me fool if you will, my Lord Bishop," said the Knight, "so long

as I give not mine own conscience cause to call me knave."

"What mean you by such words?" persisted the Bishop. "I mean, my lord,

that if the truth opened out an abyss which plunged me into hell, I

would sooner know it than attempt to enter Paradise across the flimsy

fabric of a lie."

Now during many days, Symon of Worcester had worked incessantly,

suffered much, accomplished much, surrendered much, lost much. Perhaps

it is hardly to be wondered at, that, at this juncture, he lost his

temper.

"By Saint Peter's keys!" he cried, "I care not, Sir Knight, whether you

drop to hell or climb to Paradise. But it is my business to see to it

that you do not disturb the peace of mind of the woman you have wed.

Therefore I warn you, that if you ride from here set upon so doing, you

will not reach your destination alive."

The Knight smiled. The film of weariness lifted as if by magic from

his eyes, and they shone bright and serene.

"I cannot draw my sword upon threats, my Lord Bishop; but let those

threats take human shape, and by Saint George, I shall find pleasure in

rendering a good account of them. With this same sword I once did hew

my way through a score of Saracens. Think you a dozen Worcester

cut-throats could keep me from reaching my wife?"

Something in the tone with which the Knight spoke these final words

calmed the Bishop; something in the glance of his eye quelled the angry

Prelate. In the former he recognised a depth of love such as he had

not hitherto believed possible to Hugh d'Argent; in the latter, calm

courage, nay, a serene joy at the prospect of danger, against which his

threats and fury could but break themselves, even as stormy waves

against the granite rocks of the Cornish coast.

The Bishop possessed that somewhat rare though valuable faculty, the

ability to recognise instantly, and instantly to accept, the

inevitable. Also when he had made a false move, he knew it, and was

preparing to counteract it almost before his opponent had perceived the

mistake.

So rarely was the Bishop angry, that his anger now affected him

physically, with a sickening sense of faintness. With closed eyes, he

leaned his head against the back of the chair. His face, always white

and delicate, now appeared as if carved in ivory. His lips fell apart,

but no breath issued from them. Except for a slight twitching of the

eyelids, the Bishop's countenance was lifeless.

Startled and greatly alarmed, Hugh looked around for some means whereby

he might summon help, but could see none.

Hastening to the table, he poured wine into the Venetian goblet,

brought it back, and moistened the Bishop's lips. Then kneeling on one

knee loosed the cold fingers from their grip.

Presently the Bishop opened his eyes--no longer points of blue steel,

but soft and dreamy like a mist of bluebells on distant hills. He

looked, with unseeing gaze, into the anxious face on a level with his

own; then turned his eyes slowly upon the ruby goblet which the Knight

had lifted from the floor and was trying to hold to his lips.

Waving it away, the Bishop slipped the finger and thumb of his left

hand into his sash, and drew out a small gold box of exquisite

workmanship, set with emeralds.

At this he gazed for some time, as if uncertain what to do with it;

then touched a spring and as the lid flew open, sat up and took from

the box a tiny white tablet. This he dropped into the wine.

The Knight, watching with anxious eyes, saw it rapidly dissolve as it

sank to the bottom.

But all consciousness of the tablet, the wine, or the kneeling Knight,

appeared to have instantly faded from the Bishop's mind. He lay back

gazing dreamily at a banner which, for no apparent reason, stirred and

wafted to and fro, as it hung from an oaken beam, high up among the

rafters.

"Wherefore doth it waft?" murmured the Bishop, thereby adding greatly

to the Knight's alarm. "Wherefore?--Wherefore?--Wherefore doth it

waft?"

"Drink this, Reverend Father," urged the Knight. "I implore you, my

dear lord, raise yourself and drink."

"Methinks there must be a draught," mused the Bishop.

"Yea, truly," said the Knight, "of your famous Italian wine. Father, I

pray you drink."

"Among the rafters," said the Bishop. But he sat up, took the goblet

from the Knight's hand, and slowly sipped its contents.

Almost at once, a faint tinge of colour shewed in his cheeks and on his

lips; his eyes grew bright. He smiled at the Knight, as he placed the

empty goblet on the table beside him.

"Ah, my dear Hugh," he said, extending his hand; "it is good to find

you here. Let us continue our conversation, if you are sufficiently

rested and refreshed. I have much to say to you."

In the reaction of a great relief, Hugh d'Argent seized the extended

hand and fervently kissed the Bishop's ring.

It was the reverent homage of a loyal heart. Symon of Worcester, as

with a _Benedicite_ he graciously acknowledged it, suffered a slight

twinge of conscience; almost as unusual an experience as the ebullition

of temper. He took up the conversation exactly at that point to which

it best suited him to return, namely, there where he had made the first

false step.

"Therefore, my dear Hugh, I have now given you in detail the true

history of the vision, making it clear that we owe it, alas! to earthly

devotion, rather than to Divine interposition--though indeed the one

may well be the means used by the other. It remains for us to

consider, and to decide upon, the best line to take with Mora in order

to safeguard most surely her peace of mind, and permanently to secure

her happiness."

"I have considered, Reverend Father," said the Knight, simply; "and I

have decided."

"What have you decided to do, my son?" questioned Symon of Worcester,

in his smoothest tones.

"To make known to Mora, so soon as I return, the entire truth."

The Bishop cast his eyes upward, to see whether the banner still waved.

It did.

Undoubtedly there must be a current of air among the rafters.

"And what effect do you suppose such a communication will have, my son,

upon the mind of your wife?"

"I am not called to face suppositions, Reverend Father; I am simply

confronted by facts."

"Precisely, my son, precisely," replied the Bishop, pressing his

finger-tips together, and raising them to his lips. "Yet even while

dealing with causes, it is well sometimes to consider effects, lest

they take us wholly unawares. Do you realise that, as your wife felt

justified in leaving the Nunnery and wedding you, solely by reason of

our Lady's miraculously accorded permission, when she learns that that

permission was not miraculous, she will cease to feel justified?"

"I greatly fear it," said the Knight.

"Do you yourself now consider that she was not justified?"

"Nay!" answered the Knight, with sudden vehemence. "Always, since I

learned how we had been tricked by her sister, I have held her to be

rightfully mine. Heaven knew, when she made her vows, that I was

faithful, and she therefore still my betrothed. Heaven allowed me to

discover the truth, and to find her--alive, and still unwed. To my

thinking, no Divine pronouncement was required; and when the Holy

Father's mandate arrived bringing the Church's sanction, why then

indeed naught seemed to stand between us. But Mora thought otherwise."

A tiny gleam came into the Bishop's eyes; an exceedingly refined

edition of the look of cunning which used to peep out of old Mary

Antony's.

"Have you ever heard tell, my son, that two negatives make an

affirmative? Think you not that, in something the same way, two

deceptions may make a truth. Mora was deceived into entering the

Convent, and deceived into leaving it; but from out that double

deception arises the great truth that she has, in the sight of Heaven,

been all along yours. The first deception negatives the second, and

the positive fact alone remains that Mora is wedded to you, is yours to

guard and shield from sorrow; and those whom God hath joined together,

let no man put asunder."

Hugh d'Argent passed his hand across his brow.

"I trust the matter may appear thus to Mora," he said.

The banner still wafted, gently. The Bishop gave himself time to

ponder whence that draught could come.

Then: "It will not so appear," he said. "My good Hugh, when your wife

learns from you that she was tricked by Mary Antony, she will go back

in mind to where she was before the spurious vision, and will feel

herself to be still Prioress of the White Ladies."

"I have so felt her, since the knowledge reached me," agreed the Knight.

The efficacy of the soothing drug taken by the Bishop was strained to

its utmost.

"And what then do you propose to do, my son, with this wedded Prioress?

Do you expect her to remain with you in your home, content to fulfil

her wifely duties?"

"I fear," said the Knight sadly, "that she will leave me."

"And I am certain she will leave you," said the Bishop.

"It was largely this fear for the future which brought me at once to

you, my lord. If Mora desires, as you say, to consider herself as she

was, before she was tricked into leaving the Convent, will you arrange

that she shall return, unquestioned, to her place as Prioress of the

White Ladies of Worcester?"

"Impossible!" said the Bishop, shortly. "It is too late. We can have

no Madonna groups in Nunneries, saving those carven in marble or stone."

To which there followed a silence, lasting many minutes.

Then the Knight said, with effort, speaking very low: "It is _not_ too

late."

Instantly the keen eyes were searching his face. A line of crimson

leapt to the Bishop's cheek, as if a whip-lash had been drawn across it.

Presently: "Fool!" he whispered, but the word savoured more of pitying

tenderness than of scorn. Alas! was there ever so knightly a fool, or

so foolish a knight! "What was the trouble, boy? Didst find that

after all she loved thee not?"

"Nay," said Hugh, quickly, "I thank God, and our Lady, that my wife

loves me as I never dreamed that such as I could be loved by one so

perfect in all ways as she. But--at first--all was so new and strange

to her. It was wonder enough to be out in the world once more, free to

come and go; to ride abroad, looking on men and things. I put her

welfare first. . . . Nay, it was easy, loving her as I loved, also

greatly desiring the highest and the best. Father, I wanted what you

spoke of as the Madonna in the Home. Therefore--'twas I who made the

plan--we agreed that, the wedding having of necessity been so hurried,

the courtship should follow, and we would count ourselves but

betrothed, even after reaching Castle Norelle, for just so many days or

weeks as she should please; until such time as she herself should tell

me she was wishful that I should take her home. But--each day of the

ride northward had been more perfect than that which went before; each

hour of each day, sweeter than the preceding. Thus it came to pass

that on the very evening of our arrival at Mora's home, after parting

for the night at the door of her chamber, we met again on the

battlements, where years before we had said farewell; and there, seated

in the moonlight, she told me the wonder of our Lady's grace in the

vision; and, afterwards, in words of perfect tenderness, the even

greater wonder of her love, and that she was ready on the morrow to

ride home with me. So we parted in a rapture so deep and pure, that

sleep came, for very joy of it. But early in the morning I was wakened

by a rapping at my door, and there stood Brother Philip, holding your

letter, Reverend Father."

"Alas!" said the Bishop. "Would that I had known she would have

whereby to explain away thy memory of that which I had said."

Yet the Bishop spoke perfunctorily; he spoke as one who, even while

speaking, muses upon other matters. For, within his secret soul, he

was fighting the hardest temptation yet faced by him, in the whole

history of his love for Mora.

By rapid transition of mind, he was back on the seat in the garden of

the White Ladies' Nunnery, left there by Mary Antony while she went to

fetch the Reverend Mother. He was looking up the sunny lawn toward the

cloisters, from out the shade of the great beech tree. Presently he

saw the Prioress coming, tall and stately, her cross of office gleaming

upon her breast, her sweet eyes alight with welcome. And at once they

were talking as they always talked together--he and she--each word

alive with its very fullest meaning; each thought springing to meet the

thought which matched it.

Next he saw himself again on that same seat, looking up the lawn to the

sunlit cloisters; realising that never again would the Prioress come to

greet him; facing for the first time the utter loneliness, the

irreparable loss to himself, of that which he had accomplished for Hugh

and Mora.

The Bishop's immeasurable loss had been Hugh's infinite gain. And now

that Hugh seemed bent upon risking his happiness, the positions were

reversed. Would not his loss, if he persisted, be the Bishop's gain?

How easy to meet her on the road, a few miles from Worcester; to

proceed, with much pomp and splendour, to the White Ladies' Nunnery; to

bid them throw wide the great gates; to ride in and, then and there,

reinstate Mora as Prioress, announcing that the higher service upon

which the Holy Father had sent her had been duly accomplished. Picture

the joy in the bereaved Community! But, above and beyond all, picture

what it would mean to have her there again; to see her, speak with her,

sit with her, when he would. No more loneliness of soul, no more

desolation of spirit; and Mora's conscience at rest; her mind content.

But at that, being that it concerned the woman he loved, the true soul

of him spoke up, while his imaginative reason fell silent.

Never again could the woman who had told Hugh d'Argent, in words of

perfect tenderness, the wonder of her love, and that she was ready on

the morrow to ride home with him, be content in the calm of the

Cloister.

If Hugh persisted in this folly of frankness and disturbed her peace,

she might leave him.

If the Bishop made the way easy, she might return to the Nunnery.

But all the true life of her would be left behind with her lover.

She would bring to the Cloister a lacerated conscience, and a broken

heart.

Surely the two men who loved her, if they thrust away all thought of

self, and thought only of her, could save her this anguish.

At once the Bishop resolved to do his part.

"My dear Hugh," he said, "you did well to come to me in order to

consult over these plans before taking the irrevocable step which

should set them in motion. I, alone, could reinstate your wife as

Prioress of the White Ladies; moreover my continued presence here would

be essential, to secure her comfort in that reinstatement. And I shall

not be here. I am shortly leaving Worcester, leaving this land and

returning to my beauteous Italy. The Holy Father has been pleased to

tell me privately of high preferment shortly to be offered me. I have

to-day decided to accept it. I return to Italy a Cardinal of Holy

Church."

Hugh rose to his feet and bowed. An immense scorn blazed in his eyes.

"My Lord High Cardinal, I congratulate you! That a cardinal's hat

should tempt you from your cathedral, from this noble English city,

from your people who love you, from the land of your birth, may perhaps

be understood. But that, for the sake of Church preferment, however

high, you should willingly depart, leaving Mora in sorrow, Mora in

difficulty, Mora needing your help----"

The Knight paused, amazed. The Bishop, who seldom laughed aloud, was

laughing. Yet no! The Bishop, who never wept, seemed near to weeping.

The scales fell from Hugh's eyes, even before the Bishop spoke. He

realised a love as great as his own.

"Ah, foolish lad!" said Symon of Worcester; "bent upon thine own ways,

and easy to deceive. When I spoke of going, I said it for her sake,

hoping the prospect of my absence might hold you from your purpose.

But now truly am I convinced that you are bent upon risking your own

happiness, and imperilling hers. Therefore will I devise some means of

detaining the Holy Father's messenger, so that my answer need not be

given until two weeks are past. You will reach Mora, at longest, five

days from this. As soon as she decides what she will do, send word to

me by a fast messenger. Should she elect to return to the Nunnery,

state when and where, upon the road, I am to meet her. Her habit as

Prioress, and her cross of office, I have here. The former you

returned to me, from the hostel; the latter I found in her cell. You

must take them with you. If she returns, she must return fully robed.

If, on the other hand, she should decide to remain with you; if--as may

God grant--she is content, and requires no help from me, send me this

news by messenger. I can then betake myself to that fair land to which

I first went for her sake; left for her sake, and to which I shall most

gladly return, if her need of me is over. The time I state allows a

four days' margin for vacillation."

"My lord," said the Knight, humbly, "forgive the wrong I did you.

Forgive that I took in earnest that which you meant in jest; or rather,

I do truly think, that which you hoped would turn me from my purpose.

Alas, I would indeed that I might rightly be turned therefrom."

"Hugh," said the Bishop, eagerly, "you deemed her justified in coming

to you, apart from any vision."

"True," replied the Knight, "but I cannot feel justified in taking her,

and all she would give me, knowing she gives it, with a free heart,

because of her faith in the vision. Moments of purest joy would be

clouded by my secret shame. Being aware of the deception, I too should

be deceiving her; I, whom she loves and trusts."

"To withhold a truth is not to lie," asserted the Bishop.

"My lord," replied Hugh d'Argent, rising to his feet and standing

erect, his hand upon his sword, "I cannot reason of these things; I

cannot define the difference between withholding a truth and stating a

lie. But when mine Honour sounds a challenge, I hear; and I ride out

to do battle--against myself, if need be; or, if it must so be, against

another. On Eastern battle-fields, in Holy War, I won a name known

throughout all the camp, known also to the enemy: 'The Knight of the

Silver Shield.' Our name is Argent, and we ever have the right to

carry a pure silver shield. But I won the name because my shield was

always bright; because not once in battle did it fall in the dust;

because it never was allowed to tarnish. So bright it was, that as I

rode, bearing it before me, reflecting the rays of the sun, it dazzled

and blinded the enemy. My lord, I cannot tarnish my silver shield by

conniving at falsehood, or keeping silence when mine Honour bids me

speak."

Looking at the gallant figure before him, the Bishop's soul responded

to the noble words, and he longed to praise them and applaud. But he

thought of Mora's peace of mind, Mora's awakened heart and dawning

happiness. For her sake he must make a final stand.

"My dear Hugh," he said, "all this talk, of a silver shield and of the

challenge of honour, is well enough for the warrior on the

battle-field. But the lover has to learn the harder lesson; he has to

give up Self, even the Self which holds honour dear. When you polished

your silver shield, keeping it so bright, what saw you reflected

therein? Why, your own proud face. Even so, now, you fear the

faintest tarnish on your sense of honour, but you will keep that silver

shield bright at Mora's expense, riding on proudly alone in your glory,

reflecting the sun, dazzling all beholders, while your wife who loved

and trusted you, Mora, who told you the sweet wonder of her love in

words of deepest tenderness, lies desolate in the dark, with a

shattered life, and a broken heart. Hugh, I would have you think of

the treasure of her golden heart, rather than of the brightness of your

own selfish, silver shield."

"Selfish!" cried the Knight. "Selfish! Is it selfish to hold honour

dear? Is it selfish to be ashamed to deceive the woman one loves?

Have I, who have so striven in all things to put her welfare first,

been selfish towards my wife in this hour of crisis?"

He sat down, heavily; leaned his elbows on his knees, and dropped his

head into his hands.

This attitude of utter dejection filled the Bishop with thankfulness.

Was he, in the very moment when he had given up all hope of winning,

about to prove the victor?

"Perilously selfish, my dear Hugh," he said. "But, thank Heaven, no

harm has yet been done. Listen to me and I will shew you how you may

keep your honour safely untarnished, yet withhold from Mora all

knowledge which might cause her disquietude of mind, thus securing her

happiness and your own."
