"Now, what on earth happened?" Pen cried.
Uncle Denny looked at Jim and Jim shook his head. "I'm not going to talk about it," he said. "I've a right to keep silence."
Pen bounced up and down on the seat impatiently. "You haven't any such right, Jim Manning. You've got to tell me what you said about Sara."
"Aw, let's forget it!" answered Jim wearily. "I'm sorry I ever even told Uncle Denny."
He leaned back and closed his eyes and his tired face touched Pen's heart. "You poor dear!" she exclaimed. "It was awfully hard on you to lose the race."
Jim's mother patted her boy's hand. "You are a very blind girl, Penelope," she said. "And I'm afraid it will take long years of trouble to open your eyes. We all must just stand back and wait."
The little look of pre-knowledge that occasionally made Pen's eyes old came to them now as she looked at Jim's mother. "Did you learn easily, Aunt Mary?"
The older woman shook her head. "Heaven knows," she answered, "I paid a price for what little I know, the price of experience. I guess we women are all alike."
When they reached the brownstone front, Jim went to bed at once and the matter of the race was not mentioned among the other three at supper. Pen was offended at what she considered the lack of confidence in her and withdrew haughtily to her room. Uncle Denny went out and did not return until late. Jim's mother was waiting for him in their big, comfortable bedroom.
Dennis peeled off his coat and vest and wiped his forehead. "Mary," he said, "I've been talking to the policeman who helped Jim. He says it was a deliberate knockout Sara gave Jim. He was standing right beside them at the time."
