Answer:
“A Retrieved Reformation”
1. At the beginning of the story, Ben Price rightly thinks that the bank robberies under investigation are committed by Jimmy Valentine, because they bear his signature style.
2. Towards the end of the story, Ben Price's opinion changed completely. Despite Jimmy Valentine's changed identity, Ben Price, correctly recognized Jimmy Valentine after the latter confirmed his true identity by unknowingly demonstrating his stylish ingenuity by opening the locked door. Since, Jimmy Valentine decided to surrender himself for arrest, Ben Price must have concluded that Jimmy was actually a changed man, especially now that he had fallen in love with Annabel.
