Upstairs in her own apartment which she had kept for some days on pretext of illness sat the Princess Margaret, in company' of Madame de Berny, wife of the French minister, and of the Marquis de Coeuvres, Henry's special envoy, and a few other Frenchmen. She was passionately fond of dancing. The adoring cardinal described her as marvellously graceful and perfect in that accomplishment. She had begged her other adorer, the Marquis Spinola, "with sweetest words," that she might remain a few days longer in the Nassau Palace before removing to the Archduke's residence, and that the great general, according to the custom in France and Flanders, would be the one to present her with the violins. But Spinola, knowing the artifice concealed beneath these "sweetest words," had summoned up valour enough to resist her blandishments, and had refused a second entertainment.

It was not, therefore, the disappointment at losing her ball that now made the Princess sad. She and her companions saw that there had been a catastrophe; a plot discovered. There was bitter disappointment and deep dismay upon their faces. The plot had been an excellent one. De Coeuvres had arranged it all, especially instigated thereto by the father of the Princess acting in concurrence with the King. That night when all was expected to be in accustomed quiet, the Princess, wrapped in her mantilla, was to have stolen down into the garden, accompanied only by her maid the adventurous and faithful Philipotte, to have gone through a breach which led through a garden wall to the city ramparts, thence across the foss to the counterscarp, where a number of horsemen under trustworthy commanders were waiting. Mounting on the crupper behind one of the officers of the escort, she was then to fly to the frontier, relays of horses having been provided at every stage until she should reach Rocroy, the first pausing place within French territory; a perilous adventure for the young and delicate Princess in a winter of almost unexampled severity.

On the very morning of the day assigned for the adventure, despatches brought by special couriers from the Nuncius and the Spanish ambassador at Paris gave notice of the plot to the Archdukes and to Conde, although up to that moment none knew of it in Brussels. Albert, having been apprised that many Frenchmen had been arriving during the past few days, and swarming about the hostelries of the city and suburbs, was at once disposed to believe in the story. When Conde came to him, therefore, with confirmation from his own letters, and demanding a detachment of the body-guard in addition to the burgher militiamen already granted by the magistrates, he made no difficulty granting the request. It was as if there had been a threatened assault of the city, rather than the attempted elopement of a young lady escorted by a handful of cavaliers.

The courtyard of the Nassau Palace was filled with cavalry sent by the Archduke, while five hundred burgher guards sent by the magistrates were drawn up around the gate. The noise and uproar, gaining at every moment more mysterious meaning by the darkness of night, soon spread through the city. The whole population was awake, and swarming through the streets. Such a tumult had not for years been witnessed in Brussels, and the rumour flew about and was generally believed that the King of France at the head of an army was at the gates of the city determined to carry off the Princess by force. But although the superfluous and very scandalous explosion might have been prevented, there could be no doubt that the stratagem had been defeated.

Nevertheless, the effrontery and ingenuity of de Coeuvres became now sublime. Accompanied by his colleague, the resident minister, de Berny, who was sure not to betray the secret because he had never known it—his wife alone having been in the confidence of the Princess—he proceeded straightway to the Archduke's palace, and, late in the night as it was, insisted on an audience.

Here putting on his boldest face when admitted to the presence, he complained loudly of the plot, of which he had just become aware, contrived by the Prince of Conde to carry off his wife to Spain against her will, by main force, and by assistance of Flemish nobles, archiducal body-guard, and burgher militia.

It was all a plot of Conde, he said, to palliate still more his flight from France. Every one knew that the Princess could not fly back to Paris through the air. To take her out of a house filled with people, to pierce or scale the walls of the city, to arrange her journey by ordinary means, and to protect the whole route by stations of cavalry, reaching from Brussels to the frontier, and to do all this in profound secrecy, was equally impossible. Such a scheme had never been arranged nor even imagined, he said. The true plotter was Conde, aided by ministers in Flanders hostile to France, and as the honour of the King and the reputation of the Princess had been injured by this scandal, the Ambassador loudly demanded a thorough investigation of the affair in order that vengeance might fall where it was due.

The prudent Albert was equal to the occasion. Not wishing to state the full knowledge which he possessed of de Coeuvres' agency and the King's complicity in the scheme of abduction to France, he reasoned calmly with the excited marquis, while his colleague looked and listened in dumb amazement, having previously been more vociferous and infinitely more sincere than his colleague in expressions of indignation.

The Archduke said that he had not thought the plot imputed to the King and his ambassador very probable. Nevertheless, the assertions of the Prince had been so positive as to make it impossible to refuse the guards requested by him. He trusted, however, that the truth would soon be known, and that it would leave no stain on the Princess, nor give any offence to the King.

Surprised and indignant at the turn given to the adventure by the French envoys, he nevertheless took care to conceal these sentiments, to abstain from accusation, and calmly to inform them that the Princess next morning would be established under his own roof; and enjoy the protection of the Archduchess.
