There was something so peculiarly aggressive in the duke's manner that an angry retort trembled on Paul's lips.

"Did you not receive it from a lady?"

Then the truth flashed upon Paul. This signet must have belonged to the duke, inasmuch as it bore his motto. An historic heirloom, it had been given by him to the Princess Natalie, and had been lost by her in the secret pa.s.sage where Paul had found it. No wonder that Bora was incensed at its re-appearance in this fashion! Jealousy caused him to draw an altogether erroneous conclusion, and unfortunately it was impossible for Paul to set him right without entering into the particulars of his sojourn at Castel Nuovo.

"A lady gave you that ring."

"There your grace errs."

"That's a lie," cried Bora savagely.

"Softly, your grace," remonstrated Radzivil, glancing nervously around. "Let us have no scandal in public." With difficulty Paul restrained his anger.

"Your grace's language is extremely offensive, but I am willing to make all allowances. I do not wish to quarrel with you. This seal was not given to me by a lady. I found it, and you claim it as yours. I am quite willing to restore it."

Bora took Paul's self-restraint for cowardice.

"You found it? Where? When? Under what circ.u.mstances?"

"Those are questions that I must decline to answer."

"You refuse?"

"Most certainly."

"Then you shall fight me."

Paul, thoroughly roused by the duke's arrogant manner, was not at all averse to accepting this challenge.

Then he thought of Barbara. The affair could not be hidden. She would learn that his first act on coming into Czernova was to fight a duel with her future consort. He would thus appear in her eyes as a brawling swashbuckler presuming on her affection to protect him from the consequences of his acts.

"No, your grace, I shall not fight," he replied quietly.

"Finding it easier to meet Afghans than a Czernovese," sneered Bora.

"Have you ever noticed, Radzivil, how brave these English are against all the savage races of the world,--how reluctant to face the European? If you will not fight I cannot, of course, compel you. But I can at least brand you as a coward."

And lifting the cane that he carried he brought it down heavily across Paul's cheek.

"Your grace!" exclaimed Radzivil, and filled with disgust and anger he walked away to the far end of the balcony.

The bronze had faded from Paul's face leaving it deadly white save for a livid stripe on the left cheek.

"Will you fight me now?" said the duke with a sneering smile and raising his cane again, "or does your cowardice require a further stimulus?"

"Fight you? Yes, by heaven!" said Paul, with a deep inspiration. "Send your second here without delay to meet mine. I hold no further parley with you. My sword shall speak for me."

A gleam of ferocious joy pa.s.sed over the duke's face.

"My second shall attend yours within an hour. But first a caution to Radzivil. He hath too talkative a tongue, and this matter must be kept secret."

He turned from Paul, who sat down, the cynosure of many eyes. The loungers on the balcony, the hotel-attendants, the pa.s.sers-by on the boulevard, had seen the duke's action, and concluded that in his usual sweet fashion he was simply chastising the impertinence of one of his own subordinates.

And as Paul sat there thinking, first of the insult he had received, and then of the fair, graceful head of Barbara pillowed on the breast of this savage, he felt the devil of hatred rising within him.

"By G.o.d, I'll kill him!" he muttered between his set teeth. "I shall be doing Barbara a service. He to marry her, forsooth!"

The Duke of Bora, not at all ashamed of his display of pa.s.sion, vexed only that Radzivil should have shown such marked disapproval, moved forward to the table where the premier sat with wine before him.

The latter durst offer no more than mild remonstrances, for he occupied a delicate position. It was not polite to make an enemy of one destined to be the Prince Consort of Czernova.

"Your grace, you forget that duelling is forbidden by the law."

"I am the heir-apparent, and above the law," returned Bora haughtily.

"You will not find the princess taking that view of the matter.

Remember how earnest she was in advocating the Anti-duelling Act. For one of her own ministers to fly in the face of it is to treat her with contempt. Your grace is acting very unwisely--acting in a manner, pardon me for saying it, that may lead to the forfeiture of her hand."

"Bah! my good Radzivil, be but discreet and she will never hear of it.

Remember," he added with a menacing air, "if her Highness becomes cognizant of this affair I shall know who was her informant."

He tossed off a gla.s.s of wine, and shot a ferocious glance in Paul's direction.

"Who could avoid blazing forth?" he presently remarked. "Do you know, Radzivil, that that sapphire seal was a gift of mine to Natalie?

Whenever I have had occasion to refer to it she has looked embarra.s.sed--why?"

"Probably because she lost it, and has not liked to say so; and inasmuch as it is now in the Englishman's hands it is evident that he must have found it."

"The finding of the seal would be a very innocent matter; why, then, does he refuse to state the circ.u.mstances?"

Radzivil did not reply, as he might very well have replied, that the mildest-natured individual would have taken umbrage at the duke's insolent manner. He merely remarked,--

"What would your grace infer?"

"That the seal was given to yon fellow by Natalie herself."

"Your grace must be mistaken. This is Captain Woodville's first visit to Czernova. When and where could the princess have seen him?"

"Where? Why not in Dalmatia? Ah! light at last," muttered Bora, grinding his teeth and gripping his sabre-hilt with a murderous look towards the distant Paul.

"Your grace, explain."

"Why did Natalie extend her stay in Dalmatia from three to six months?

There is the cause," he added, indicating Paul.

"A secret amour with him at a time when she was affianced to you! You wrong the princess," said Radzivil coldly.

"Wait!" exclaimed the duke, excitement gleaming from his eyes. "Why did she return so melancholy in mood that I almost doubted whether she were the lively Natalie of former days? There is the cause!" he added, again indicating Paul.
