When Art Mysteries Become Personal Adventures
What if a stolen masterpiece could speak to you through your dreams? "Chasing Vermeer" has captivated readers since its 2004 release, selling over a million copies and earning comparisons to "The Da Vinci Code" for younger readers. Blue Balliett's debut novel weaves mathematics, art history, and supernatural elements into an intellectual adventure that J.K. Rowling called "wonderfully intriguing." The book has been translated into 29 languages and adapted into a play performed in schools worldwide. Its popularity sparked renewed interest in Vermeer's paintings, with museum attendance spiking after publication. This puzzle-within-a-story approach has made it a favorite among educators who use it to introduce students to art appreciation and pattern recognition-proving that learning about art history can be as thrilling as any detective story.
Chapitre 2
The Mysterious Letters That Started It All
On a chilly October night in Chicago, as wind whips through the gothic architecture of Hyde Park, three solitary individuals receive identical mysterious letters. Each cream-colored envelope, addressed in precise calligraphy, contains an unsigned message requesting help to solve a centuries-old crime against a great painter. The letters promise substantial rewards - including a share of a potential multimillion-dollar discovery - but warn of grave danger if shown to authorities. Despite their initial skepticism, all three recipients - a university professor, a local bookstore owner, and an elderly art collector - find themselves inexplicably drawn to the possibility of uncovering a historical truth that has remained buried for generations.
Meanwhile, sixth-grader Calder Pillay navigates the halls of the Laboratory School with his ever-present set of pentominoes jingling in his pocket. These mathematical puzzle pieces - each containing five squares arranged in different configurations - serve as both his comfort object and his lens for understanding the world. When his teacher Ms. Hussey, known for her unconventional methods, assigns the class to find stories about letters that changed lives, Calder begins noticing peculiar connections involving the number twelve: twelve letters in "pentominoes," twelve different pentomino shapes, twelve months since his best friend Tommy moved to New York. Though brilliant at recognizing mathematical patterns and solving complex puzzles, he struggles with expressing his ideas in writing assignments, often losing points for organization despite his deep understanding of the material.
His classmate Petra Andalee, equally captivated by Ms. Hussey's mysterious teaching style, possesses a quiet intensity and keen observational skills. Half-Dutch and feeling caught between cultures, she spends lunch periods reading in hidden corners of the library, preferring the company of books to the complicated social dynamics of middle school. Both children live in the intellectual haven of Hyde Park, surrounded by the University of Chicago's imposing buildings and diverse academic community, where they navigate their multicultural identities and complex family expectations - Calder with his mathematician father and artist mother, Petra with her translator father and absence of a mother.
Their separate worlds begin to overlap when they independently spot Ms. Hussey at Powell's used bookstore one rainy afternoon. Through the foggy windows, they watch their teacher frantically purchasing an armload of books with intriguing titles about art forgery, famous heists, and unsolved murders. This chance encounter - and their shared curiosity about their teacher's unusual behavior - forms the catalyst for an unexpected friendship between two observant outsiders. Little do they know that they've been specifically chosen as key players in an international art mystery that will test their combined skills of pattern recognition, historical analysis, and courage in ways they never imagined.
Chapitre 3
Art's Hidden Truths and Unexpected Connections
When Ms. Hussey takes her class on a field trip to the Art Institute of Chicago, Petra and Calder find themselves drawn to exploring beyond the designated areas. Their independent spirits lead them into trouble when they're caught by a guard near a storage room, but Ms. Hussey surprisingly approves of their initiative. The awkward beginnings of their friendship are complicated by classroom teasing and mutual suspicion, yet they share a growing curiosity about the boundaries between art and reality.
Back in the classroom, Ms. Hussey introduces Picasso's provocative idea that "art is a lie that tells the truth" and assigns students to choose household objects that feel like art. This assignment pushes Petra to question what truly makes something art, reflecting on how Caillebotte's "Rainy Day" painting at the Art Institute evokes powerful feelings in her. Meanwhile, she discovers an unusual book called "Lo!" by Charles Fort in Powell's bookstore giveaway box-left there by a mysterious man with suspenders.
Fort's book becomes Petra's obsession. It documents inexplicable phenomena from around the world-venomous snakes appearing in backyards, worms falling with snowflakes, periwinkles raining from the sky. Fort spent twenty-seven years researching these unexplained occurrences, challenging conventional thinking with his philosophy that people often twist reality to fit their expectations rather than seeing what's actually there.
That night, Petra experiences something extraordinary-a vision of an old-fashioned woman in a yellow jacket who seems to recognize her. This profound connection leaves Petra feeling that there is much more to be uncovered about the world than most people realize. The boundary between art and reality begins to blur as Petra senses that paintings might hold secrets beyond their frames, waiting for the right observers to notice them.
Chapitre 4
When Patterns Become Personal
Calder contemplates Ms. Hussey's art assignment while manipulating his pentominoes, mathematical puzzle pieces that help him think. He retrieves a special wooden box with silver inlaid corners-a gift from his Grandma Ranjana. The box features a painting of a thoughtful man in a bathrobe leaning over a table with maps and instruments, possibly a geographer. As afternoon sunlight creates geometric patterns through his leaded glass windows-what his grandmother called a "rainbow bath"-Calder begins describing the box for his assignment.
His work is interrupted when he notices Ms. Hussey and the bookstore owner Mr. Watch helping an irritable elderly woman named Mrs. Sharpe who has stumbled outside. Later that evening, Calder receives a coded letter from his friend Tommy, who has moved to New York. The letter, written in their secret pentomino code, reveals that a boy in Tommy's neighborhood has mysteriously disappeared.
As Calder and Petra's friendship develops over their shared interest in unusual occurrences, they begin connecting dots. When Petra shares excerpts from Fort's book about mysterious disappearances, Calder links it to Tommy's letter about the vanished boy called Frog. While delivering books for Mr. Watch to Mrs. Sharpe's house, Calder makes a stunning discovery-the painting on his wooden box is a reproduction of Vermeer's "The Geographer."
Researching Vermeer at the library, Calder learns that the Dutch painter died penniless despite his extraordinary talent, created only thirty-five known works, and left behind many mysteries about his subjects and techniques. Calder begins noticing patterns in Vermeer's paintings-recurring objects like rugs, maps, and yellow jackets-and wonders if there might be hidden codes in the repetitions and careful geometries.
The connections deepen on Halloween when Petra creates a costume unknowingly resembling a woman from Vermeer's painting "A Lady Writing" from 1665-a painting she's never seen before but somehow dreamed about. This uncanny coincidence startles them both, suggesting forces beyond coincidence might be at work.
Chapitre 5
The Mystery Deepens
The strange coincidences multiply as Calder and Petra discover three more Vermeer paintings featuring the same woman in the yellow jacket from Petra's dream. Fascinated by how Petra dreamed of something she'd never seen, they begin documenting unexplained events, connecting their recent experiences: Calder's box with The Geographer, Petra's dream, their discussions about Charles Fort, and their Halloween costumes.
Their research reveals that Vermeer was baptized on Halloween 1632-the very day they began investigating him-and they discover how little is known about the mysterious artist's life. Calder suggests looking for patterns or secret codes in Vermeer's recurring motifs. After their research, they create a ritual with blue M&Ms to symbolize their secret investigation, agreeing the color blue has "a rare and mysterious taste."
The coincidences become increasingly unsettling. When Calder's father mentions his grandmother's preference for red in Vermeer paintings, it adds to their growing sense that they've fallen inside a puzzle they can't escape. As Calder reflects, "It was one thing if you were using a handful of plastic pieces to find solutions to a puzzle; it was another if you felt like you'd fallen inside a puzzle and couldn't get out."
Their fears materialize on November 5th when they discover shocking news: the Vermeer painting "A Lady Writing" has been stolen while in transit between Washington D.C. and the Art Institute of Chicago. The newspaper headline "VERMEER VANISHES" confirms their worst fears-the painting they'd been mysteriously drawn to has disappeared, with a note left behind reading "YOU WILL COME TO AGREE WITH ME." Both children realize their strange experiences weren't coincidental.
At school, Ms. Hussey appears with her arm in a sling from a fall during a power outage, adding to the mounting sense of wrongness. When they spot Ms. Hussey meeting secretly with Mr. Watch at Powell's bookstore, their suspicions deepen further. The mystery has moved from the realm of coincidence into something far more sinister and personal.
Chapitre 6
Art World in Chaos
The theft of Vermeer's masterpiece creates immediate worldwide uproar. Ms. Hussey's classroom transforms into a combination museum and laboratory with walls plastered with Vermeer reproductions. Students examine paintings through magnifying glasses, studying details and recording conclusions about which works are "real." While the classroom buzzes with excitement, the art world engages in angry, closed-door discussions about recovering the painting without yielding to blackmail.
The public rebels against art experts, feeling entitled to their own opinions about Vermeer's work. When Ms. Hussey's class votes that Vermeer's early and late works are indeed suspicious, she responds with uncharacteristic flatness, looking frightened.
Meanwhile, Mrs. Sharpe invites Calder and Petra for tea in her Vermeer-inspired home with blue Delft tile and Dutch furnishings. During their tense conversation, she expresses admiration for the thief's intelligence and echoes Fort's belief that "people don't look carefully enough at what is around them." Her lack of distress about the theft strikes the children as suspicious.
After tea, Calder receives another coded letter from Tommy, only to discover Tommy's phone has been disconnected. Meanwhile, Petra learns her father has left on a mysterious business trip. While discussing these developments, Petra has a vision of the Lady Writing speaking to her, leading her to believe the painting might be hidden in a dark wooden storage place.
The next morning, Ms. Hussey presents a hypothetical scenario to her class about receiving a threatening letter from a thief. Petra realizes this matches a letter she found on Harper Avenue and writes Calder a note about it. When Ms. Hussey confiscates their note, the children grow concerned about their teacher's unusual behavior.
Another full-page ad from the thief appears in newspapers worldwide with the message: "You have come to agree with me. They will come to agree with you." The ad creates renewed public interest, with previous messages having sparked demonstrations and merchandise. Ms. Hussey questions whether the thief might be more than one person, adding another layer to the mystery.
Chapitre 7
Dangerous Discoveries
Calder delivers books to Mrs. Sharpe, using the opportunity to explore her house for clues. He notices several wardrobes similar to those in Vermeer paintings and numerous hiding places. Later, he receives a coded letter from Tommy that suggests Tommy needs rescue. Calder and Petra spend the weekend selling brownies to raise money for Tommy and his mother.
On Sunday, they learn that Mrs. Sharpe has gone to the police about receiving a threatening letter matching the one Ms. Hussey described to the class. Calder's father reveals that Mrs. Sharpe's husband was a Vermeer scholar who had been murdered in Europe decades ago while researching the artist. That night, police cars surround Mrs. Sharpe's house while Calder and Petra wonder if Mrs. Sharpe might be cleverly framing herself.
The next day at school, Ms. Hussey is absent, and rumors spread that she's been arrested as a suspect in the Vermeer theft. Her class erupts in chaos, with students arguing about her innocence and accusing each other of betrayal. The substitute teacher struggles to maintain control, eventually distributing word problems to keep everyone occupied.
News breaks that both Ms. Hussey and Mrs. Sharpe received the same threatening letter about the Vermeer theft. Ms. Hussey returns to school, visibly nervous despite police protection. The class learns that Mrs. Sharpe's husband was a Vermeer expert who died mysteriously in Amsterdam thirty-one years ago after claiming a breakthrough discovery about Vermeer's work.
Later, Petra overhears Ms. Hussey on the phone saying "it is here" before breaking into tears. Concerned for their teacher's safety, Petra and Calder decide to actively search for the painting, theorizing it might be hidden at University School. Using pentominoes as guides and clues, they begin systematically mapping and searching the school buildings, focusing on Gracie Hall.
Chapitre 8
The Final Puzzle Pieces
Calder and Petra convince Mrs. Trek, the Lower School principal, to let them into the basement to complete their "mapping project." While searching the supply room, they discover a small package wrapped in brown paper behind some picture frames-the right size for the Vermeer painting. When Mrs. Trek returns unexpectedly, Petra distracts her while Calder stays hidden with the package. Mrs. Trek locks the basement door, accidentally trapping Calder inside.
While Petra desperately tries to find a way to free him, Calder waits in complete darkness, comforting himself by thinking about the treasure he might be holding and creating pentomino puzzles in his mind to pass the time.
Walking home alone while Calder is sick, Petra finds a scrap of paper in Mrs. Sharpe's hedge-another letter beginning "Dear Friend, I would like your help in identifying a crime that is now centuries old..." They place it in their Geographer's box, worried they might be in danger.
Meanwhile, a new book called "The Vermeer Dilemma: What Happens Now?" appears in stores for just $1.50, discussing how the theft has positively engaged the public with art. People worldwide are examining Vermeer's work with newfound interest, even questioning expert opinions about authenticity.
Walking to school, Petra and Calder discover an ambulance outside Mrs. Sharpe's house. The elderly woman has broken her leg in a fall and entrusts them with mailing a letter addressed to Ms. Hussey. The children debate opening it first, with Calder suggesting they steam it open and reseal it in a new envelope. As they argue about the ethics of this "detective work," a stranger accidentally knocks the letter from Calder's hand and drops it into the mail slot before they can decide.
When they visit Mrs. Sharpe in the hospital later, she thanks them for mailing her letter and offers them chocolate lollipops instead of tea. Despite initially scolding them for almost opening her mail, she softens and shares that she wrote to Ms. Hussey about their shared Nantucket connection.
Chapitre 9
The Truth Revealed
After visiting Mrs. Sharpe, Calder receives exciting news that Tommy and his mother are moving back to Hyde Park. Tommy also mentions that Frog was found in Washington D.C. and had sent a postcard of the stolen Vermeer from the National Gallery. Determined to continue their search, Petra and Calder explore King Hall at the University School, looking for paneling where the painting might be hidden.
Finding nothing, they cross to Delia Dell Hall, an elaborate Gothic building with carved wood panels, leaded glass windows, and hidden doors. As they explore the ornate rooms and staircases, Petra suddenly makes a connection between the building's features and Mrs. Sharpe's pentomino word game-"monkey, panel, vines, flute, finds."
That night, Petra reconsiders her suspicions about Mrs. Sharpe and Ms. Hussey, wondering if her imagination has run wild. But by morning, her practical reasoning seems cowardly, and she embraces possibility again. Her mood shifts dramatically when she reads the newspaper and discovers a new letter from the thief threatening to destroy A Lady Writing by January 11th if museums don't change the attributions of certain Vermeer paintings.
Horrified, Petra and Calder decide to investigate Delia Dell Hall themselves. At the hall, they encounter a man with thick eyebrows and a foreign accent whom Petra recognizes from the post office. Taking a basement entrance, they explore the building's maze-like interior until they spot Petra's father carrying a suspicious rectangular package and meeting with the foreign man.
Calder and Petra formulate a plan to return to Delia Dell that night. During their conversation, they discover they share the same birthday-both turning twelve on December 12th. Calder realizes this connection to twelves might be significant to the puzzle they're solving.
That evening, they sneak into Delia Dell Hall after spotting the post office man leaving. Working methodically through the dark building with a faltering flashlight, they search for hidden compartments. Calder has a revelation about the number twelve and leads Petra to the twelfth step of the staircase. Beneath it, they discover a hidden panel containing the stolen Vermeer painting wrapped in velvet. They're moved to tears by the delicate beauty of the Lady, noticing she wears exactly twelve pearls-ten in her necklace plus two earrings.
Chapitre 10
The Mystery Unravels
Carefully wrapping the painting, they attempt to escape, triggering an alarm as they flee into the night. A mysterious man chases them through the playground. When Calder falls, he bravely threatens to damage his bundle (which actually contains only newspapers and a sign) if the man approaches. Petra reaches a restaurant and finds a university police officer, but when they return to the playground, they find only Calder's bloodied sweatshirt. Meanwhile, the man steals the real painting from the police car.
Distraught after failing to protect Calder, Petra waits at home while everyone searches for him. Suddenly sensing the Lady is nearby, she grabs a snow shovel and investigates the neighboring Castiglione's tree house. Finding boot prints beneath it, she cautiously climbs up and discovers Calder curled around the painting bundle, injured but alive.
The FBI investigation reveals the thief was actually Xavier Glitts, "Glitter Man," leader of an international crime ring with advanced degrees and homes worldwide. His elaborate scheme involved posing as Tommy's stepfather "Old Fred" while gathering ideas from Ms. Hussey about Vermeer attribution. He planned to sell the painting for sixty million dollars, making it appear destroyed while confusing authorities with his three letters to different recipients.
Mrs. Sharpe's husband had discovered something revolutionary about Vermeer's paintings before his mysterious murder, and she believes the woman in "A Lady Writing" has been sending her messages to clear Vermeer's name. The children discover numerous connections involving the number twelve: twelve people with twelve letters in each name, pentomino letters in everyone's first initials, and significant dates.
Within weeks of solving the mystery, several Vermeer paintings worldwide are relabeled as "Attributed to Johannes Vermeer." Mrs. Sharpe rewards Calder and Petra with meaningful gifts-an antique globe and carpet for Calder, and a writing desk and Dutch pearls for Petra.
Through their adventure, Calder and Petra learn that seeing isn't just looking-it's understanding the patterns that connect us all, and recognizing that sometimes what appears to be coincidence might actually be something far more meaningful. As Mrs. Sharpe suggests, perhaps the Lady herself had been waiting centuries for the right observers to notice her silent messages and solve a centuries-old artistic mystery.
Chapitre 11
Art's Enduring Mysteries
The story of "Chasing Vermeer" reminds us that art isn't just something to be passively observed in museums-it's a living conversation across centuries. Johannes Vermeer, who died penniless despite his extraordinary talent, created only thirty-five known paintings, yet his work continues to captivate and mystify viewers hundreds of years later.
What makes this story so compelling is how it transforms art appreciation from a stuffy academic exercise into an exciting adventure. The pentominoes that Calder carries become more than just mathematical puzzles-they're tools for understanding how patterns connect seemingly unrelated events. Charles Fort's philosophy that "people don't look carefully enough at what is around them" becomes a guiding principle for the young detectives and for readers alike.
The book challenges us to question whether coincidences are truly random or if they might reveal deeper patterns we've simply failed to notice. When Petra dreams of a woman in a painting she's never seen, when Calder's wooden box contains a reproduction of "The Geographer," when both children discover they share a birthday-these connections suggest that perhaps we're all part of larger patterns waiting to be discovered.
Most importantly, the story reminds us that expertise isn't always found where we expect it. Two observant twelve-year-olds notice what art experts and FBI agents miss because they approach the mystery with open minds, willing to see connections that others dismiss. As Mrs. Sharpe tells them, "You've been brave enough to trust your own eyes."
In a world increasingly dominated by specialists and experts, "Chasing Vermeer" makes a compelling case for the value of interdisciplinary thinking-combining art, mathematics, history, and intuition to solve problems that can't be addressed through any single approach. Perhaps that's why the book continues to captivate readers of all ages, reminding us that the greatest mysteries often hide in plain sight, waiting for someone curious enough to really look.
