Speedy was an ambitious mouse. She didn't want to be stuck in her cage with her dull sisters, she wanted to get out and see the world!
Speedy's boy was very upset when he found that she had escaped from her cage but never lost hop that she would return to him.
He tried to set up traps to catch her but she was too smart for that. As a final attempt to catch her, her boy put her cage on the floor before he went out.
Would she come back to him? Would she be in the cage when he arrived home?
