“They run this way, sire,” said David, with respectful ardour:

“If it please your majesty,” interrupted a harsh voice, “I will ask a question or two of this rhymester. There is little time to spare. I crave pardon, sire, if my anxiety for your safety offends.”

“The loyalty,” said the king, “of the Duke d’Aumale is too well proven to give offence.” He sank into his chair, and the film came again over his eyes.

“First,” said the duke, “I will read you the letter he brought:

“ ‘To-night is the anniversary of the dauphin’s death. If he goes, as is his custom, to midnight mass to pray for the soul of his son, the falcon will strike, at the corner of the Rue Esplanade. If this be his intention, set a red light in the upper room at the south-west corner of the palace, that the falcon may take heed.’

“Peasant,” said the duke, sternly, “you have heard these words. Who gave you this message to bring?”

“My lord duke,” said David, sincerely, “I will tell you. A lady gave it me. She said her mother was ill, and that this writing would fetch her uncle to her bedside. I do not know the meaning of the letter, but I will swear that she is beautiful and good.”

“Describe the woman,” commanded the duke, “and how you came to be her dupe.”

“Describe her!” said David, with a tender smile. “You would command words to perform miracles Well, she is made of sunshine and deep shade. She is slender, like the alders, and moves with their grace. Her eyes change while you gaze into them; now round, and then half shut as the sun peeps between two clouds. When she comes, heaven is all about her; when she leaves there is chaos and a scent of hawthorn blossoms. She came to me in the Rue Conti, number twenty-nine.”

“It is the house,” said the duke, turning to the king, “that we have been watching. Thanks to the poet’s tongue, we have a picture of the infamous Countess Quebedaux.”

“Sire and my lord duke,” said David, earnestly, “I hope my poor words have done no injustice. I have looked into that lady’s eyes. I will stake my life that she is an angel, letter or no letter.”

The duke looked at him steadily. “I will put you to the proof,” he said, slowly. “Dressed as the king, you shall, yourself, attend mass in his carriage at midnight. Do you accept the test?”

David smiled. “I have looked into her eyes,” he said. “I had my proof there. Take yours how you will.”

Half an hour before twelve the Duke d’Aumale with his own hands set a red lamp in a south-west window of the palace. At ten minutes to the hour, David, leaning on his arm, dressed as the king, from top to toe, with his head bowed in his cloak, walked slowly from the royal apartments to the waiting carriage. The duke assisted him inside and closed the door. The carriage whirled away along its route to the cathedral.

On the qui vive at a house at the corner of the Rue Esplanade was Captain Tetreau with twenty men, ready to pounce upon the conspirators when they should appear.

But it seemed that, for some reason, the plotters had slightly altered their plans. When the royal carriage had reached the Rue Christopher, one square nearer than the Rue Esplanade, forth from it burst Captain
