But Chester’s laugh dies away as the sentries at the gate bar their passage by crossed pikes, and their ensign says hoarsely: “The countersign, señor!”

Santa Maria de la Cruz” whispers Guy.

The pikes drop as the officer waves his sword, and they step past him through the heavy Gothic archway. At this moment a light flashing from a flambeau stuck into a niche in the heavy masonry falls upon the lady, outlining her figure more strongly. Catching sight of this the Spanish officer doffs his steel cap, and bowing to the very ground, says: “Had I known it was you, Excelentisima, my challenge would not have been so peremptory!”

“You but did your duty, señor,” says the unknown. A second later she has left Guy’s arm and having taken the young officer aside, who stands before her with uncovered bended head, is whispering something to him in Spanish very rapidly.

A portion of the ensign’s answer comes to Guy’s ear: “No, Excelentisima, he has not arrived from Brussels.”

“Then papa will not be anxious for me this night,” says the lady quickly. Retaking Chester’s arm she says to the young officer: “You will attend us to the quarters of the Countess of Mansfeld.”

A moment later, preceded by the Spanish ensign, they pass through the gateway to the main parade ground of the Citadel, and passing between piles of cannon balls and all the vast implements of attack and defense of the great fortress, move towards what are apparently the officers’ quarters. From the windows of one of these, evidently much larger and more commodious and elegant than the rest, come the lights of festival and the music of the dance. Situated immediately in the rear of the bastion of Paciotto, the distance to this is quite short, and Guy has little chance of conversation with his companion, being compelled to speed by the storm, which is still cold and biting, and causes the lady to hug her wraps very tightly about her.

They enter at a little side door of the house, a man servant in gorgeous livery receiving them and immediately bowing to the earth.

“The countess expected me?” remarks Guy’s charge hurriedly. [[29]]

“Yes, Excelentisima, the fête of this evening is in your honor. You have been detained? It is now near midnight,” answers the servitor, again bowing.
