Frau Katherine and Twonette put aside their tapestry, and went with Yolanda to question Castleman in the arbor.

"Well, uncle, where are our guests?" asked Yolanda.

"They are not at the inn, and have not been there since nearly a fortnight ago," answered Castleman.

"Gone!" cried Yolanda, aflame with sudden anger. "He gave me his word he would not go. I'm glad he's gone, and I hope I may never see his face again. I deemed his word inviolate, and now he has broken it."

"Do not judge Sir Max too harshly," said Castleman; "you may wrong him. I do not at all understand the absence of our friends. Grote tells me they went to the river one night to bathe and did not return. Their horses and arms are at the inn. Their squires, who had left them two hours before, have not been seen since. Grote has heard nothing of our friends that will throw light on their whereabouts. Fearing to get himself into trouble, he has stupidly held his tongue. He was not inclined to speak plainly even to me."

"Blessed Mother, forgive me!" cried Yolanda, sinking back upon a settle. After a long silence she continued: "Two weeks ago! That was a few days after the trouble at the bridge."

"What trouble?" asked Castleman.

"I'll tell you, uncle, and you, tante. Twonette already knows of it," answered Yolanda. "Less than three weeks ago I was with Sir Max near the moat bridge. It was dark--after night--"

"Yolanda!" exclaimed Castleman, reproachfully.

"Yes, uncle, I know I ought not to have been there, but I was," said Yolanda.
