Irene returned the laugh with one equally insincere, saying to her guest:
"Help yourself to whatever books you like, neighbor. Carry them home, read them and return them at your convenience."
"You are exceedingly kind," answered Agatha and resumed her examination of the titles. Mary Louise had not observed the tell-tale expression on Miss Lord's face but she was shrewd enough to detect an undercurrent of ice in the polite phrases passing between her companions. She was consumed with curiosity to know more of the letter which Irene had found in the book but did not again refer to it in the presence of their visitor.
It was not long before Agatha rose to go, a couple of books tucked beneath her arm.
"Will you ride with me to Millbank to-morrow?" she asked, glancing from one face to another.
Mary Louise looked at Irene and Irene hesitated.
"I am not very comfortable without my chair," she said.
"You shall have the rear seat all to yourself, and it is big and broad and comfortable. Mary Louise will ride with me in front. I can easily drive the car up here and load you in at this very porch. Please come!"
"Very well, since you are so kind," Irene decided, and after a few more kindly remarks the beautiful Miss Lord left them and walked with graceful, swinging stride down the path to the road and down the road toward the Bigbee house.
