In late 19th century London, the life of Enola, a young woman with a free spirit and brilliant intelligence, takes an unexpected turn the day her mother mysteriously disappears. Raised by her mother in an unconventional environment, far from strict Victorian norms, Enola has been educated in the art of critical thinking, fighting, and cunning. However, when her mother vanishes, Enola's life becomes complicated.
Despite the influence of her famous brother, detective Sherlock Holmes, who returns home without giving her the attention she deserves, Enola feels compelled to find her mother on her own. Wasting no time, she plunges into the streets of London, where she quickly faces a series of trials and adrenaline-fueled adventures. Along the way, she meets a young lord seeking to escape his own predicament, and together they form an unexpected alliance.
As Enola follows clues and confronts the dangers of the adult world, she also begins to discover her own sense of identity and strength. The search for her mother becomes an adventure filled with twists, mysteries, and a healthy dose of humor. Enola not only must solve the mystery of the disappearance but also challenge the social expectations of her time and prove that she is not just Sherlock's younger sister but a formidable detective in her own right.
