"My sister-in-law," she continued, "has laid her burdens upon Providence at every crisis in her life, and Providence, I must confess, has responded nobly, so far--" "Yes," said Katharine, with a laugh, for she liked the rashness which irritated the rest of the family.

"My mother's bulls always turn into cows at the critical moment." "Well," said Mrs.Milvain, "I'm glad you have some one to protect you from bulls now." "I can't imagine William protecting any one from bulls," said Katharine.
It happened that Mrs.Cosham had once more produced her pocket volume of Shakespeare, and was consulting Ralph upon an obscure passage in "Measure for Measure." He did not at once seize the meaning of what Katharine and her aunt were saying; William, he supposed, referred to some small cousin, for he now saw Katharine as a child in a pinafore; but, nevertheless, he was so much distracted that his eye could hardly follow the words on the paper.

A moment later he heard them speak distinctly of an engagement ring.
"I like rubies," he heard Katharine say.
"To be imprison'd in the viewless winds, And blown with restless violence round about The pendant world...." Mrs.Cosham intoned; at the same instant "Rodney" fitted itself to "William" in Ralph's mind.

He felt convinced that Katharine was engaged to Rodney.

His first sensation was one of violent rage with her for having deceived him throughout the visit, fed him with pleasant old wives' tales, let him see her as a child playing in a meadow, shared her youth with him, while all the time she was a stranger entirely, and engaged to marry Rodney.
But was it possible?
Surely it was not possible.
