Frank heard that sigh and faced about quickly.
"Cassie," he said, with anxiety, "you are not feeling well to-night. Your medicine has not cured you?"
She did not look him straight in the face, as she slowly answered:
"No, Frank, my medicine did not cure me, but it helped me go on and play. I was afraid I'd not be able to do that much."
"What is the matter, Cassie?"
"Oh, the same old trouble, Frank—just a lack of nerve and life. I'm discouraged, too."
"About what?"
She hesitated, and then of a sudden she answered:
"I may as well tell you. It's about pop."
