Edna, daughter of Leonce, was puzzled because her doll had no heart. The ticking of her father's watch gave her an idea. She ripped the doll open and sewed the watch inside. When Leonce missed his watch he suspected a boy, who had called selling ornaments, of stealing it. The boy was searched and allowed to go. Later Edna's doll fell into the river and was being carried away when the boy came along and dived in and brought the doll to the bank. When Edna reached home, she was greatly distressed because the doll's heart had ceased to beat. "I am crying because my doll's heart is drowned," she said. Leonce then guessed what had happened, and found his watch, rather the worse for the immersion. The boy was soon discovered and Edna prettily rewarded him for rescuing her doll.
