A flawless diamond. A perfect thief. A mystery hidden in plain sight.

In the heart of Kolkata's legendary Bow Bazar lies Diamond Jewelers, a prestigious gem boutique renowned for its exquisite stones and impeccable reputation. But when a high-value diamond vanishes without a trace?despite state-of-the-art security and constant surveillance?the store's quiet prestige is shattered.

Enter Deepak Barik, a seemingly polished customer with an eye for quality?and a secret agenda. With nothing but a missing payment card and a polite smile, he walks out of the shop... and with him, the prized diamond disappears.

With no signs of forced entry, no lapses in protocol, and no suspicious activity on camera, store manager Anil Sharma is left with more questions than answers. Fearing public scandal and reputational ruin, he turns to Durjoy Bhattacharya, a discreet and cerebral private detective known for solving the unsolvable.

As Dujo picks apart the threads of the theft, he uncovers a trick so bold, so subtle, that even the cameras were fooled. But catching a thief who choreographs his crimes like a performance?and disappears into Mumbai's sprawling chaos?will take more than sharp observation. It will take instinct, patience, and a mind as sharp as the stone that was stolen.

Diamond Jewelers Mystery is a gripping detective thriller that blends the elegance of a heist with the intellectual thrill of investigation. Set between the glitter of Kolkata's gem market and the shadows of Mumbai's streets, this story will keep you turning pages until the very last reveal.
