Santu Roy was never known for being careful. Where others saw neat rows of tools and tidy cables, Santu saw possibility—an ancient radio repurposed into a Bluetooth speaker, an old bicycle dynamo hooked to a clutch of LEDs, a salvaged phone battery that could power a dozen small devices. In Ratanpur, a narrow riverside town with a single movie theater and too many mango trees, Santu’s little shop of “almost-trashes” hummed with life. Locals called it Santu Portable because you could always find something useful there that had once been junk.
Kakababu—Keshab Sen—stood apart from most visitors. He had the tired, attentive air of a man who had spent years looking for truth behind simple things. Retired schoolteacher, amateur archaeologist, and occasional solver of local mysteries, Kakababu came to Santu’s shop every Sunday with a newcomer’s curiosity and an old friend’s patience. He liked Santu’s inventions but liked the man more: Santu’s inventiveness reminded Kakababu of how cleverness and kindness could travel together.
One humid afternoon, as monsoon winds loosened the dust on the road, Santu burst into Kakababu’s home with breathless excitement. He clutched a battered metal box—no bigger than a shoe box—its latch rusted, its leather strap frayed.
“Look!” Santu declared, eyes bright. “Portable treasure!”
Kakababu took the box gently. The metal carried the smell of river mud and old paper. Etched faintly on its lid were letters almost worn away: S.P. 1939.
“Where from?” Kakababu asked.
“From the bungalow by the old jetty,” Santu said. “They’re clearing it. Old Mr. Dutta moved cities. The caretakers threw some things out. I snagged this before the garbage cart came.”
Inside the box, carefully wrapped in oilcloth, lay a small brass compass, a yellowing notebook bound in cracked leather, and a folded photograph—two young men in colonial khaki, their smiles easy, the river behind them. The compass needle shivered and then steadied. On the notebook’s first page, in a hand both hurried and exact, was a single line: For journeys that must not be lost.
Kakababu, whose heart quickened at clues, read. The notebook belonged to Samar Prakash—S.P.—a surveyor who had worked mapping the Sundarbans in 1939. The entries spoke of tidal calculations and mangrove markers, but tucked among charts were odd notes: a promised meeting with a man called “Ravi,” a reference to a “portable” that would keep something safe, and, toward the back, a map with an X beneath the inked words: Old Pagla Island.
Kakababu’s mind stitched a hundred possible threads. An old portable—maybe a box, maybe a device—meant secrets hidden during war or flight. 1939 was the eve of upheaval. The Sundarbans had always been a place where maps hid stories, and coastal surveyors often encountered both.
They left that evening, riding Santu’s sputtering scooter toward the jetty. The sky kept the soft purple of coming rain. The bungalow was empty, a hulking memory of verandahs and wide windows. The caretaker, a thin man with tired eyes, nodded when they explained they were only curious; the bungalow’s treasures were already parceled away. He shrugged. “If it was in the gutter, well, that’s how life goes.”
Kakababu turned the compass over and traced its worn casing. The needle pointed not toward north but, annoyingly, toward the bungalow’s old garden. Santu laughed. “Maybe it likes the tea stall.”
They followed the notebook’s map the next morning. Pagla Island was less an island than a raised mudbank, half-swallowed by reeds and the slow generosity of the river. Local fishermen called it Pagla—mad—because the tides there moved in tricks, hiding and revealing patches of land like a child’s game. The map’s X lay under a lone peepal tree, its roots curled like sleeping snakes.
They reached Pagla at low tide, ankle-deep in cool mud. Santu unrolled a tarp and began to dig with a borrowed spade, singing a nonsense song to keep his spirits high. Kakababu watched the sky, conserving patience like store-bought rice. After an hour, there was a hollow in the earth and a small, rusted tin—another portable. It rattled with something inside.
When Santu pried the tin open, five small, brittle envelopes slid free. Each held a slim piece of faded cloth and a thin copper coin stamped with an unfamiliar emblem. Tucked beneath them was a letter, written in a fine hand and signed “Samar.” The letter read, in part: Keep these things with the compass. For safe passage. For remembrance. For those who might return.
Kakababu frowned. Coins and cloth and a compass—remembrance, yes, but what did safe passage mean? He flipped the notebook further. A later entry described a “portable with pictures” given to a “boy with the quick laugh” and advised that any who needed the portable should bring the compass and the phrase “not lost.”
At the inn that night, over steaming rice and fish, Kakababu and Santu went through the possibilities. Maybe the portable was a kit for navigation. Maybe it was a family heirloom stuffed with tokens of courage to take on journeys. Or perhaps it was something deeper, left to comfort those fleeing sudden danger—proof of identity, of belonging. kakababu o santu portable
They decided to ask around. The photograph led them next to the river’s oldest house, where Mrs. Banerjee, eighty and sharp as the cut of winter, lived with parrots and memory. She recognized one of the men in the photograph at once. “Ravi,” she whispered. “He married my cousin before the war. He went to Calcutta and then—” Her eyes shifted toward the window. “He never came back.”
Mrs. Banerjee remembered talk of people leaving the region hurriedly during those years, carrying only what they could. “They called some things ‘portables’ then,” she said. “Small boxes of life—letters, coins, photographs—so families could start again.” Her voice softened. “If you find it, give it someone who remembers them.”
That night, rain came, heavy and clean. The town smelled of wet earth. Kakababu slept poorly, turning the notebook’s clues in his head. The phrase “not lost” nagged at him. It felt less like an instruction and more like a promise—an assurance tucked into a compass case so later hands would know what to do.
Three days later, at the market, a young woman interrupted Santu while he bartered for a used battery. She had the shape of someone who had walked away from a bigger life: precise jaw, wary eyes. Her name was Anu Dutta—the granddaughter of the bungalow’s owner. She had come back to help clear the family home and, she said, to understand the fragments of a past she did not know.
When Kakababu showed her the brass compass and the photograph, she broke down quietly. “Ravi was my grandfather’s friend,” she said between tears. “They left letters and small things for those who might return, but my family never had much to keep.” She held the compass as if it were fragile glass. “My grandmother always kept talking about a portable her cousin had—’kept things safe,’ she’d say. We thought it was a story.”
Kakababu observed the worn coins, the cloth pieces, the letter. He told Anu of the notebook’s instruction and the X on Pagla. He did not bring up theories of treasure or secrets; the objects were plainly ordinary. What mattered, he decided, was their meaning.
They followed the next note in the notebook—Samar’s neat handwriting led them to an old post office ledger. With permission, the postmaster showed them grease-stained registers. Under the year 1940, there was a penciled entry about evacuees and a sealed packet labeled simply: “For Ravi—if he returns.” The packet had never left the ledger. The clerk recalled a rumor: a chest had gone missing from the docks around the time of a violent storm.
Kakababu’s curiosity hardened into conviction. The portable, he suspected, was not a single object but a set of keepsakes scattered when people fled. The compass and the envelopes were breadcrumbs. Someone—Samar, perhaps—had hidden the rest.
On the creek bank, near the old ferry crossing, Kakababu and Santu searched for the missing chest. The tide moved in with the dirty patience of the river, and fisherman’s huts crowded the bank. A boy playing with a tin boat pointed them toward a collapsed warehouse where birds nested in rafters. Inside, beneath a pile of rotting sacks, was a wooden chest sealed with an iron latch. It looked like a coffin for memories.
The latch balked, then yielded to Santu’s improvised tools. Inside lay a portable the size of a satchel: a leather-bound album, dried flowers pressed between pages, a bundle of letters tied with thread, and a small carved box of sandalwood. The carved box, when opened, revealed a single object—an old silver locket containing a faded photograph of two smiling faces and a pressed strip of paper with the word “home.”
Anu’s face, when they presented these things, was quiet astonishment. The locket was Ravi’s, her grandmother later told them, a token carried from one land to another. The album was Samar’s—he had collected the faces of those who had left, a memory for those who had stayed. The letters contained small instructions: who to look for, where to hide, a request to share these portables with those who sought them with the compass and the phrase.
It became clear: S.P. had not merely been charting river channels—he had been keeping a map of human connections. In times of chaos, people split tokens among trusted places so their identity and memory could survive even if they could not. The “portable” was both object and idea: portable hope, portable identity.
The town buzzed with the news that these items had returned. For some, it was a simple return of heirlooms. For others, it stitched together stories once broken. Anu organized a small ceremony by the river where elderly residents and descendants gathered. They passed the compass between hands, read Samar’s notes aloud, and let the words “not lost” settle like a benediction.
Kakababu, who had solved mysteries of missing cattle and mislaid deeds, found this recovery different. There was no villain to reveal, no conspiracy to unravel—only the patient, human work of memory. Santu Portable, once a name for a shop of salvaged goods, became a phrase for what they had done: to make the small portable things that carry a life travel again between hands that could keep them.
Before he left Ratanpur, Kakababu sat with Anu by the river at dusk. Boats slid along the water like ink strokes. She held the locket and the compass in her palms, and he watched her smile, something honest and soft.
“Will you keep them?” she asked.
“For now,” Kakababu said. “Things that travel sometimes want to stay put.”
Santu stood nearby, cigarette forgotten, eyes reflecting lantern light. He loved how objects could be coaxed into new lives. “We’ll call my cart Santu Portable and take these things to people who need them,” he said. “Portable, yes—but not lost.”
Kakababu laughed softly. He had always liked that word: portable. It meant movable, yes, but it also meant possible—capable of carrying meaning across time and tide.
As they packed to leave, Kakababu slipped the little notebook back into its oilcloth and placed the compass on top. He thought of Samar Prakash, who had hidden small promises in the mud and the maps, trusting that someone later would find them and make good on the past.
The river moved on. The monsoon passed. People kept their lives, salvaging what they could. And in the quiet that followed, a battered metal box with the letters S.P. painted on its lid rested on a shelf in Santu’s shop, a small shrine to the truth that some things are portable—and that, with care, they need never be lost.
Kakababu and Santu are the ultimate duo of Bengali adventure literature, and their "portable" appeal—their ability to transition from the printed page to the big screen and now into our pockets via digital media—is a testament to their enduring legacy. Created by the legendary Sunil Gangopadhyay, Raja Roychowdhury (better known as Kakababu) and his nephew Santu represent a unique blend of intellect, physical grit, and unwavering curiosity. The Dynamic Duo: Brains, Brawn, and a Crutch
At the heart of every Kakababu adventure is a fascinating subversion of the typical "action hero." Kakababu is an ex-Director of the Archaeological Survey of India who lost a leg in a tragic accident. Far from being a limitation, his crutch becomes a symbol of his resilience—and occasionally a formidable weapon.
Santu, his teenage (and later young adult) nephew, serves as the reader's surrogate. He is the legs of the operation, the quick thinker in a crisis, and the one who often balances Kakababu’s stoic, sometimes reckless obsession with historical mysteries.

In the vast, vibrant landscape of Bengali literature, few characters have captured the imagination of readers across generations quite like Raja Roychowdhury—better known as Kakababu—and his intrepid nephew, Santu. While the series is famous for its globetrotting adventures, historical mysteries, and archaeological thrills, one specific phrase has recently sparked a wave of nostalgia and practicality among fans: "Kakababu o Santu Portable."
But what exactly does "portable" mean in the context of a book series that spans over 35 novels? Is it a new app? A special edition? Or is it a state of mind? This article dives deep into the legacy of Sunil Gangopadhyay’s iconic creations and explores why the "portable" nature of their adventures is the secret to their enduring success.
Physical books take up space. A complete set of the Kakababu series could fill an entire shelf. Modern urban living, characterized by smaller apartments, encourages digital minimalism. A portable collection offers the best of both worlds: a rich library without physical clutter.
Kakababu (Raja Roy Chowdhury): He is arguably one of the most unique protagonists in Indian literature. A hero in a wheelchair who is not defined by his disability but by his capability. He represents the mind—calm, analytical, and authoritative. He commands respect not through physical dominance, but through sheer presence.
Santu (Sunil Roy Chowdhury): Santu is the reader’s surrogate. He is young, impulsive, brave, and occasionally prone to getting into trouble. He represents the body—the action. The magic of the series lies in the interplay between the two. Kakababu cannot move without help, and Santu cannot solve the mystery without guidance.
The term "Portable" has exploded in the digital age. Since the death of Sunil Gangopadhyay in 2012, there has been a massive surge in the digitization of his works. Today, a student in London or a software engineer in San Francisco can type "Kakababu o Santu portable" into a search engine and instantly find a complete collection in EPUB or PDF format. While copyright laws are strictly observed by publishers (like Ananda Publishers), the demand for a portable digital library has led to official e-book releases, making the entire series weigh less than a gram.
