About the Book: The Silver Serpent Agatha Oddly
The Silver Serpent is the third book in Lena Jones’s Agatha Oddly series. It was published in September 2019 by HarperCollins Children’s Books. The story centers on thirteen-year-old Agatha, the youngest and newest recruit to the Gatekeeper’s Guild, a secret organization connected to crime-solving and investigations.
Her latest case begins when an assistant at the National Gallery goes missing. What initially appears to be a missing-person investigation soon develops into a much larger mystery.
The book combines middle-grade mystery, detective fiction, adventure, and suspense, making it particularly appealing to readers who enjoy clever young protagonists.
Unveiling Agatha Oddly Who Is the Heroine of The Silver Serpent?
Agatha Oddlow is the heart of the series.
At thirteen, she is already an unusually determined investigator. She is curious, observant, and willing to follow a clue even when doing so becomes risky. But what makes Agatha interesting isn’t simply that she is clever.
She is also connected to the Gatekeeper’s Guild through her mother, who was an important member of the secret organization. As the youngest and newest recruit, Agatha has something to prove.
That personal connection gives the investigation an additional layer. Her cases aren’t simply puzzles to solve; they are also part of her attempt to understand her family and her place within the Guild.
In The Silver Serpent, Agatha’s development becomes particularly important because this is her first official case for the organization.
What Makes The Silver Serpent an Unforgettable Tale?
Spoiler-free summary: Agatha’s first official assignment begins with the disappearance of an assistant at London’s National Gallery.
Instead of treating the case as an ordinary missing-person investigation, Agatha starts connecting the clues. Her investigation takes her through London and toward a much larger conspiracy.
The story gradually raises the stakes as Agatha discovers that there is more behind the disappearance than she initially expected.
One of the most appealing elements is the investigative structure. Readers aren’t simply waiting for Agatha to reveal the answer. The story gives them mysteries, clues, and suspicious circumstances to consider along the way.
The result is a fast-moving detective adventure that encourages readers to keep turning pages.
A Perfect Setting for Mystery
One of the strengths of The Silver Serpent is its setting.
Instead of creating a completely imaginary world, Lena Jones places Agatha’s investigation within London. The National Gallery becomes an important location in the mystery, while Agatha’s wider investigation takes her across the city.
This gives the story a strong sense of place.
London is particularly effective for a detective story because its streets, galleries, historic buildings, and underground spaces naturally create an atmosphere of secrets and discovery.
The official Agatha Oddly website also describes Agatha traveling throughout London and going into the heart of the mystery.
For younger readers, this combination of a recognizable real-world city and a secretive detective organization makes the adventure feel both exciting and believable.
Themes of Friendship, Courage, and Determination
Although The Silver Serpent is built around a mystery, the story also explores themes that make it more than a simple whodunit.
Courage
Agatha repeatedly has to deal with situations that would make anyone hesitate. Her willingness to continue investigating demonstrates the importance of courage when facing difficult challenges.
Friendship
Agatha’s friends remain part of the wider world of the series, giving the story a sense of continuity as she takes on greater responsibilities.
Determination
Perhaps the most important theme is persistence. Agatha doesn’t simply abandon a difficult case when the clues become complicated.
These qualities help explain why young readers can connect with her as a protagonist.
A recent young-reader review also praised Agatha’s bravery and determination, recommending the book for readers interested in mystery and adventure.
How The Silver Serpent Develops the Agatha Oddly Series
One of the best reasons to read The Silver Serpent is the development of Agatha herself.
The earlier books introduce readers to Agatha and her world. By Book 3, she has gained more experience and is ready to take on greater responsibility.
Her connection to the Gatekeeper’s Guild becomes increasingly important, giving the series a larger sense of continuity.
The progression also makes the recommended reading order fairly straightforward:
- The Secret Key – Agatha Oddly Book 1
- Murder at the Museum – Agatha Oddly Book 2
- The Silver Serpent – Agatha Oddly Book 3
While The Silver Serpent can be enjoyed as an individual mystery, reading the books in order gives readers a better understanding of Agatha’s character and her relationships.

Is Agatha Oddly a Good Book Series?
Yes, especially for young mystery readers.
The appeal of Agatha Oddly comes from its combination of an intelligent young heroine, accessible mysteries, friendship, adventure, and a distinctive secret organization.
The books don’t require readers to be fans of complicated fantasy worlds or dark crime fiction. Instead, they offer mysteries that young readers can follow and enjoy.
The series is also useful for children who are beginning to explore detective fiction. Agatha encourages readers to observe details, question assumptions, and look for connections between clues.
