The Mystery of Carlitos: Mexican Mystery Stories #2

In Short

This briskly paced juvenile mystery follows three American girls—Jo Ann, Peggy, and Florence—who are vacationing in the Mexican highlands. Their encounter with a family of impoverished charcoal makers leads them to discover a young boy, Carlitos, whose striking blue eyes suggest a secret heritage. As the girls navigate the perils of the landscape, they stumble upon a plot involving a stolen silver mine and a ruthless local boss. A relic of 1930s children’s literature, the book captures the era’s adventurous spirit, blending lighthearted camaraderie with high-stakes peril.

The Story

The story opens as Jo Ann, Peggy, and Florence settle into a mountain camp near a cave inhabited by a struggling family. Jo Ann is immediately struck by the presence of a boy among the family who possesses deep blue eyes, a feature that distinguishes him from his companions. When the girls’ food supplies go missing, Jo Ann’s investigation eventually clears the cave-dwelling family of wrongdoing, but she becomes obsessed with uncovering the mystery of the boy’s origins.

The plot accelerates when the charcoal-making family is forced to flee their home due to the influence of a shadowy antagonist. The girls discover that the boy is named Carlitos and that he was abducted from his true family, who were subsequently wronged by a greedy mine owner. As the girls grow closer to the family, they learn that the "boss" of a nearby mansion is the same man who orchestrated the theft of a silver mine, known as La Esperanza, which rightfully belongs to the boy’s kin.

Determined to help, the girls begin tracking the kidnapper through the jagged, dangerous terrain. During a tense confrontation, Jo Ann attempts a daring rescue of Carlitos using a rope and a pistol, only to be captured herself by the villain. The kidnapper forces the girls and Carlitos to trek into a dark ravine, intending to silence them permanently. However, their resourcefulness pays off; by leaving a trail of clues—including a belt dropped on the path—they provide enough evidence for their rescue.

The story reaches its climax when the girls’ fathers and the local authorities intercept the captor. The villain is thwarted, and it is revealed that Carlitos’s true uncle, Mr. Eldridge, has been searching for him. The stolen mine is reclaimed, and in gratitude, the girls are gifted shares in the enterprise. The book concludes on a hopeful note, with the mine renamed the "New Hope Mine" to symbolize a fresh start for Carlitos, his protectors, and the girls, cementing a lasting bond of friendship forged in the mountain wilderness.

How It Unfolds

The discovery of the mystery While exploring near a mountain cave, Jo Ann notices a boy with unusual blue eyes living among a group of charcoal makers. This observation sparks a persistent curiosity in her, leading the girls to believe that the boy is not who he appears to be.

The missing supplies After the girls find their camp supplies stolen, they briefly suspect their neighbors, but Jo Ann soon discovers evidence that someone else is responsible. This incident serves as the catalyst for the girls to begin tracking the movements of local strangers.

The hunt begins When Carlitos and his charcoal-making guardians disappear, the girls realize they must take action to find the boy. They enlist the help of the father of the family and begin a perilous journey across the mountains on horseback.

The confrontation The girls track the kidnapper to a hidden location and attempt a rescue, but they are quickly overpowered. This harrowing sequence shifts the tone from an investigative mystery to a race for survival as they are held as prisoners in a deep ravine.

The resolution The arrival of the girls’ fathers leads to a successful rescue and the capture of the antagonist. With the truth revealed, the stolen mine is returned to its rightful owners, and the mystery of the blue-eyed boy is finally put to rest.

The People

Jo Ann is the driving force of the narrative, a proactive and courageous teenager who refuses to let a mystery go unsolved. Her tenacity is the engine of the plot, pushing the group into dangerous situations. Peggy serves as a more cautious foil, often providing the voice of reason or humor, while Florence acts as the group’s essential translator, using her grasp of Spanish to bridge the gap between the girls and the local residents.

Carlitos is the enigmatic centerpiece of the story. Though he begins as a silent, mysterious figure, he emerges as a resilient child who has been displaced from his heritage. The antagonist, referred to simply as the "boss," represents unchecked greed; he is a looming, mustache-twirling villain who exploits the local population and will stop at nothing to protect his stolen wealth. Through the girls’ intervention, these characters are transformed: the boss is brought to justice, the charcoal-making family receives life-changing support, and the girls find their confidence and worldliness expanded by their brush with danger.

In Its Own Voice

“Just wait till I get a chance to demonstrate my marksmanship, Peg; I’ll show you that I am a good shot.”

Jo Ann asserts her capability and confidence to her friend before they embark on a dangerous mission to confront a bear.

“I’m going to solve the mystery.”

Jo Ann makes this bold declaration to her friends after finding evidence that exonerates the cave family of theft.

“Didn’t you say that Esperanza means hope? It’ll mean new hope now for Carlitos and José and his family—and for us too.”

Jo Ann reflects on the symbolic significance of the reclaimed silver mine at the end of the journey.

What It's Really About

At its heart, the book explores the themes of agency, justice, and the bridge between disparate social worlds. The narrative posits that curiosity and moral courage are enough to right systemic wrongs, even when those wrongs involve powerful, predatory figures. It asks the reader to consider the value of empathy: the girls do not simply solve a puzzle; they actively choose to integrate themselves into the lives of the local population, proving that true "hope" arises from mutual support and fairness. The story emphasizes that privilege, when used with integrity, becomes a tool for restoration rather than oppression.

Why Read It Today

Readers who enjoy vintage "girl detective" fiction will find a familiar, comforting rhythm here. The book captures a specific, idealized mid-1930s perspective on travel and adventure, and the prose is straightforward and punchy. It feels like a time capsule of a more earnest, if occasionally simplistic, era of juvenile literature.

However, modern readers should be aware that the book reflects the period's attitudes toward race and class. The depiction of the "peons" and the local population is filtered through a paternalistic lens common to the 1930s, often portraying them as simple, impoverished, and dependent on the charity of the American protagonists. While the girls are genuinely kind and seek to help, the dialogue and narrative voice frequently lean into dated stereotypes that may feel jarring today. Despite these limitations, the book remains a quick, engaging read for those interested in the evolution of the mystery genre. It is an excellent choice for a reader who appreciates a fast-moving plot and a dash of historical nostalgia, provided they are prepared to navigate the period-specific tropes that define its worldview.
