Which famous detective is Enola's older brother in Enola Holmes 3?

Sherlock Holmes is Enola Holmes’s older brother in Enola Holmes 3.

The film continues the relationship established in the earlier Enola Holmes movies, where Enola is presented as the youngest child in the Holmes family and Sherlock is the famous detective among her older brothers. Henry Cavill reprises the role of Sherlock in the third film, while Millie Bobby Brown returns as Enola.

Sherlock is one of the most recognizable fictional detectives in English literature. He was created by Arthur Conan Doyle and first appeared in the 1887 novel A Study in Scarlet. The Enola Holmes films add a younger sister created by novelist Nancy Springer, making Enola a later, non-canonical addition to the Holmes family rather than a character from Doyle’s original stories.

Mycroft Holmes is another older brother and appears in the first Enola Holmes film, which can make the family relationships easy to mix up. Sam Spade and Hercule Poirot are also famous detectives, but they belong to separate fictional universes.
