Wogan had an opportunity to make certain. He knelt down and picked up the letter; the foot was a woman's. As he rose up again, the curtain ever so slightly stirred. Wogan pretended to have remarked nothing; he stood easily by the window with his eyes upon his letter and his mind busy with guessing what woman his spy might be. And he remained on purpose for some while in this attitude, designing it as a punishment. So long as he stood by the window that unknown woman cheek by jowl with him must hold her breath, must never stir, must silently endure an agony of fear at each movement that he made. At last he moved, and as he turned away he saw something so unexpected that it startled him. Indeed, for the moment it did more than startle him, it chilled him. He understood that slight stirring of the curtain. The woman now held a dagger in her hand, and the point of the blade stuck out and shone in the moonlight like a flame. Wogan became angry. It was all very well for the woman to come spying into his room; but to take a dagger to him, to think a dagger in a woman's hand could cope with him,--that was too preposterous. Wogan felt very much inclined to sweep that curtain aside and tell his visitor how he had escaped from Newgate and played hide-and-seek amongst the chimney-pots. And although he restrained himself from that, he allowed his anger to get the better of his prudence. Under the impulse of his anger he acted. It was a whimsical thing that he did, and though he suffered for it he could never afterwards bring himself to regret it. He deliberately knelt down and kissed the instep of the foot which protruded from the curtain. He felt the muscles of the foot tighten, but the foot was not withdrawn. The curtain shivered and shook, but no cry came from behind it, and again the curtain hung motionless. Wogan went out of the room and carried the letter to the Prince. The Countess of Berg was still playing upon her harp, and she gave no sign that she remarked his entrance. She did not so much as shoot one glance of curiosity towards him. The Prince carried the letter off to his cabinet, while Wogan sat down beside the Countess and looked about the room. "I have not seen Lady Featherstone this evening," said he. "Have you not?" asked the Countess, easily. "Not so much as her foot," replied Wogan.
