He did not speak. He knew not what to say. The serious nature of that theft on the previous night he realised, alas! too well. Had that intricate key plan passed from her hand, then the whole truth would have been out, and Europe must have been suddenly aflame.

As it was, his duty remained towards her, to strive to stifle the scandal and prevent the story either reaching the King’s ears or becoming public property.

Cataldi knew that the key had been stolen, and would probably inform His Majesty, in which case Hubert would be hastily summoned to audience and closely questioned.

In such circumstances what could he explain? Ay, what?

For fully five minutes the pair stood there motionless, save that with his hand he had softly stroked her cheek. Then, unable to repress the passion that arose within his bursting heart, he bent until his lips touched hers in a fierce, passionate caress.

She turned her great, expressive eyes upon his, those eyes that were so deep and fathomless, and sighed heavily as he kissed her. Her beautiful head was thrown back, displaying her slim white throat, around which was a thin platinum chain from which was suspended a tiny platinum locket encrusted with diamonds, a gift of the Tzarina. She was inexpressibly sweet and refined, her soft beauty seeming the more perfect as she stood there inert in the man’s strong arms.

Again his lips met hers. Then to his boundless joy he felt that, at the same instant she kissed him in return.

Yet next second, as though annoyed that she should have flung discretion to the winds, she gently disengaged herself from his embrace, saying in a low, pained voice:

“No, Hubert—I—I mean Mr Waldron—this is madness. I—we can never be anything but friends, alas! though I—”

She broke off short, and hot tears again filled her splendid eyes.
