1. With good deeds often come great rewards: This theme highlights how performing acts of kindness or helping others can lead to positive outcomes. In the story, the character of Sherlock Holmes exhibits this theme by solving the mystery of the blue carbuncle and rewarding the man who returned it.
2. Nothing good comes from greed: Another theme that can be derived from the story is the idea that greed and selfishness can lead to negative consequences. The characters who are motivated by greed in the narrative face challenges and do not find true success or fulfillment.
