What is the evidence that Holmes belongs to Detectives Gregson and Lestrade?

Sherlock Holmes belongs to the fictional Sherlock Holmes universe created by Sir Arthur Conan Doyle. In Doyle's stories, Holmes collaborates with a number of characters, including Detectives Gregson and Lestrade, who are often presented as local police officers seeking his assistance in solving various cases. The evidence that Holmes belongs to Gregson and Lestrade can be found in the following aspects:

1. Canon stories: In the original Sherlock Holmes canon, there are multiple instances where Holmes is referred to as assisting or working closely with both Gregson and Lestrade. They appear alongside Holmes in various adventures, such as "A Study in Scarlet," "The Adventure of the Norwood Builder," and "The Adventure of the Red Circle," among others.

2. Collaboration: Both Gregson and Lestrade are often portrayed as seeking Holmes' expertise and relying on his incredible deductions to assist in their investigations. They regularly turn to him for help, recognizing his exceptional detective skills.

3. Acknowledgment by Holmes: Sherlock Holmes himself acknowledges his collaboration with Gregson and Lestrade. He often discusses his partnership with them, referring to them as "Scotland Yard's finest" or addressing them as respected colleagues.

4. Complementary skills: Gregson and Lestrade, while competent detectives in their own right, often recognize Holmes' superior deductive abilities and unique approach to crime-solving. They appreciate his expertise and frequently call on him for assistance, which further strengthens the evidence of their collaboration.

It should be noted that Sherlock Holmes exists in various adaptations beyond the original canon, including movies, TV shows, and other literary works. In some of these adaptations, Holmes may have different relationships with Gregson and Lestrade. However, the evidence mentioned above is specific to the original Sherlock Holmes stories by Sir Arthur Conan Doyle.

Based on the Sherlock Holmes stories written by Sir Arthur Conan Doyle, the evidence that Holmes belongs to Detectives Gregson and Lestrade can be inferred from the following:

1. Collaborative Cases: Holmes frequently assists both Detective Gregson from Scotland Yard and Detective Lestrade from the Metropolitan Police in their investigations. This suggests a professional relationship and mutual dependence.

2. Acknowledgments: In several stories, both Gregson and Lestrade acknowledge Holmes' superior deductive skills and rely on his expertise to solve complex cases. They often seek his assistance and value his analytical insights.

3. Overlapping Investigations: It is common for Holmes to be involved in cases that either Gregson or Lestrade is already working on. This suggests a level of involvement and an established connection between them.

4. Mutual Respect: Although there are occasional friendly rivalries and disagreements between Holmes and the detectives, there is an underlying respect between all parties. Holmes recognizes their competence and occasionally gives credit to their investigative progress.

It is important to note that Holmes does not exclusively work with either Gregson or Lestrade, and he also collaborates with other detectives and clients throughout the stories. However, the aforementioned evidence suggests a consistent association and partnership between Holmes, Gregson, and Lestrade.
